Nick Sercombe “We’ve fi nally realised our dairying dream” 14

This issue contains our annual calf rearing special, which always proves

popular in our independent surveys. And readers should be pleased with this year’s offering, which comprises features on how to increase heifer rearing effi ciency and maximise the return on the considerable investment made in growing replacement stock. Starting on page 23, we’ve information about new tools and innovations that can help monitor and improve calf growth rates, as well as an article on liver fl uke and the impact that the parasite can have on achieving that all-important 24-month target for age at fi rst calving.A recent study has also shown that calf birth weights may be lower than they were just a few years ago on some units – particularly those that are cross breeding. So it may be prudent to check your calf weights and ensure that you’re not overfeeding your young calves. Sticking with the next generation – this time of the dairy producer variety –

we have an inspiring story, on page 14, about a young couple who fi nally have a fi rm footing on the dairying ladder. And they’re managing and milking some of their own cows, as part of a larger herd, on an impressive new unit. Investing in new facilities may seem extravagant in this tough and volatile economic climate, but one business consultant says that it could make sound business sense on some units. Not only could targeted investment help to reduce costs, but now may also be an ideal time to get a good deal from local suppliers and tradesmen. See page 45 to fi nd out more.Roger Evans offers some sobering food for thought on dairy unit security, as well as his views on ‘extreme vegans’, on page 20. And we’ve an inspiring ‘Overalls off’ star – a Cumbria-based fi rst responder – on page 12. Find out more about his invaluable life-saving role and see if it motivates you to try to set aside some time to volunteer.

Take action now to get ahead

Added sugars will be essential this winter

Still time to spray grassland weeds

Face the reality of global markets – and the price volatility that goes with them. That was the message to delegates from independent agricultural economist Sean Rickard, speaking at the Organic Milk Suppliers Co-operative conference in October.The ‘Positive Dairying: winning in a global marketplace’ event saw producers, industry leaders and stakeholders pack the National Motorcycle Museum in Birmingham to listen to a range of speakers delivering their opinions on the future of UK dairying.Mr Rickard focused on the future options for those in this sector. “UK dairy farming is now part of a global industry and is, therefore, subject to the vicissitudes of short-term shocks to global markets, and longer-term global trends,” he said. “Even relatively small mismatches between supply and demand lead to

large fluctuations in price. Surviving producers must learn to cope with greater volatility.“The dairy industry needs a new mindset and not only to deal with short- term volatility, but also to rise to the longer-term global opportunities and sustainability challenges,” he explained. He added that individual producers have four options: “The first is to leave the

industry. The second is to adjust by increasing productivity and/or increasing returns, which is obviously only an option where the farm has the scope and ability to improve. “Thirdly, they can adopt a ‘buffer capability’ strategy whereby they are able to weather an input or output price shock without substantial change. Or, a fourth option is to make a radical change by investing in horizontal or vertical diversification, but this is high risk and, in truth, only a few will succeed here.“Worldwide, the underlying trend in demand for dairy products is expected to rise at a rate of 2% per year and the removal of EU quotas gives the UK dairy industry an opportunity. “Remember, we have some of the best dairy dairies in the world,” he concluded. “This gives us enormous opportunities. Let’s take action now to get ahead.”

Producers looking to maximise milk from forage this winter are being warned to ensure that rations include a minimum of 5% added sugars and that they don’t exceed a 3:1 ratio of starch-to-sugar.“Cereals may be cheap this year, but over relying on starch to supply fermentable energy risks triggering sub-acute ruminal acidosis,” said KW nutritionist Mark Scott. “Sugars reduce that risk, and are essential to drive microbial breakdown of forage fibre in the rumen and capture the rapidly available protein in grass silages. “But the residual sugars in preserved

forages aren’t particularly accessible, so extra sugars are needed or the rate and extent of fibre digestion won’t be as great, and milk-from-forage will be reduced.”Trouw Nutrition data shows that first- cut silages averaged 68% digestibility this year, yet it only takes a reduction of between 4% and 5% in forage digestibility, from imbalanced energy supply in the rumen, to cut that to 65%. “Make the most of forage by keeping available sugar levels above that 5% threshold,” Mr Scott adds. “That typically means adding around 2.5kg per cow per

day of a high sugar molasses-based liquid feed, such as cane molasses, or around 6kg of a highly cost-effective whey permeate-based feed, like LactoBoost.”

There is still time to spray weeds like docks and dandelions and buttercups in grass fields – but only just. Treating them now will save a job early next year, when there are plenty of other tasks to do and opportunities can be limited if spring comes late.“This is quite a good time to spray translocated products on grassland – as long as temperatures hold up and weeds are leafy and actively growing,” says Dow AgroSciences’ Brent Gibbon.“It is also important to have at least

seven days of relatively mild weather after application, to allow the herbicide to work fully. Take note of the weather forecast before getting the sprayer out or phoning the contractor.“The odd frosty night during a fine week should not be a problem – but once there is a run of two or three consecutive frosts, weeds will stop growing and it will be too late to spray,” he adds. “It is essential that the leaves are dry when treated, so do not spray after or just before rain.”

Docks in fields that had final cuts of silage taken a few weeks ago are now at the perfect rosette stage for spraying, as are any thistles that were topped in late summer. “But it is not worth spraying old and tatty weeds, like docks with leaves made threadbare from disease or insect attack.“And be aware that some products, such as Thistlex and PastorPro, must not be used after 31 October, although others like DoxstarPro and Forefront T can be used after this date.”

The Jersey cow’s ability to turn grass into high quality milk – up to 20% higher in protein

and calcium than that produced by other breeds – certainly contributes to its status as the second most popular dairy breed in the world, after the Holstein.But for the focused group of Jersey dairy producers on the Channel Island, which gave the cow its name more than 400 years ago, the challenge of producing milk as efficiently as possible is exactly the same as for any other producer. “The island herd is able to maintain an outstandingly high health status – Jersey is officially free from bovine TB, brucellosis and EBL, BVD, IBR and leptospirosis,” says Andrew le Gallais, one of the island’s producers and chairman of Jersey Dairy, the farmer-owned processor co-operative. “But our costs of production is high relative to herds on the mainland and to be able to continue to milk Jerseys profitably and sustainably we must manage our units as efficiently as possible,” Jersey Dairy processes more than 250,000 litres of milk every week and produces a range of luxury dairy products, including long-life milk, cream, butter, cheese, ice cream and yoghurt. These are supplied both locally and exported to high-value developing world markets, such as China. “All our products have a unique and very clear provenance and a strong brand image, but like any other producers we must continually strive to keep our production costs as low as possible,” adds Andrew.

Carbon-footprint assessmentsTo help its producers identify opportunities to improve efficiency, Jersey Dairy recently commissioned Alltech E-CO2 to undertake carbon footprint assessments for each of its 21 producer suppliers. Industry research shows that the most efficient dairy herds are those with the lowest carbon footprint.

As the squeeze on milk price continues,

producers could be forgiven for placing their

herd’s carbon footprint low on their list of

priorities. But assessing herd emissions can also

identify where financial savings can be made.

“The Swift-EA environmental assessments con-sistently highlight areas where producers can often make significant financial savings,” says Alltech E-CO2’s Victoria Roberts.“With 80% of the carbon emissions associated with the production of a litre of milk coming from the dairy unit, there’s plenty to work with. However, many producers assume that any move to reduce their carbon footprint is bound to add cost. But, actually, the opposite is true.”Ms Roberts explains that a unit’s carbon footprint is the total volume of greenhouse gas (GHG) emissions caused directly or indirectly by that farm divided by the output generated in the same period. “The dairy unit’s carbon footprint quantifies the emissions of the three major GHGs relating to the unit’s output before it leaves the farm gate.”The gasses produced are carbon dioxide (CO2), from fossil fuel combustion for example; nitrous oxide (N20), from the degradation of crop residue and nutrients in the soil; and methane (CH4), from rumen fermentation and waste and manure management.The 21 unit assessments revealed a significant variation in the carbon emissions of the Jersey dairy herds on the island. The carbon footprints ranged from 2.32kg CO2 emitted per litre of milk produced to 1.105kg CO2 emitted per litre, with the weighted average carbon footprint for the whole group equating to 1.183kg CO2 emitted per litre (FPCM).“And, interestingly, the herd with the largest carbon footprint had a very low milk yield, which means the farm inputs and cow enteric emissions – which represent around 40% of total dairy farm GHG emissions – are being offset against much fewer litres of milk than the average farm, which was producing 5,432 litres per cow.”

Financial benefitsOnce in possession of the basic carbon footprint analysis, using Alltech E-CO2’s Dairy ‘What If?’ Tool allows the Jersey Dairy suppliers to examine the effects and potential financial benefits of different management decisions. Following the input of basic data including herd size and average cow liveweight and milk price received, the tool then asks for yield, culling, fertility, calving interval, feed regime and crop/resource use information. It incorporates a dashboard-style presentation of current carbon emissions per litre of milk produced and the potential ‘what if’ implications – and the financial impact – of different management changes.

“For example, we know that by improving the health of the rumen and the cow, more milk will be produced while at the same time lowering methane emissions. And healthy cows live longer, lowering culling and replacement rates,” says Ms Roberts. “Emissions spread across a short milking life are very ineffi cient, whereas if they can be spread across more lactations you help to offset the emissions produced during the unproductive rearing period.

Cost savingsAll these factors boost your on-farm effi ciency and potential profi tability, while at the same time reducing your environmental impact.”The tool shows that increasing the average milk yield to that achieved by the top 20% of units on the island would

save £440 per cow per year. In addition, more signifi cant savings could be achieved by reducing average cow culling and feed rates.“For example, cutting the average culling rate of 19% to 17% would save a herd £3,393. And by reducing the average herd feeding rate of 0.33kg per litre to a target of 0.3kg per litre – well within reach of this group of suppliers – an extra £7,402 per million litres of milk could be found,” says Ms Roberts. She adds that if the herd with the highest calving interval (455 days) could reduce it to that of the farm with the lowest interval (365 days), this unit could save £15,477.Alltech E-CO2 is also able to advise the group on a raft of additional savings, identifying more effi cient fuel, electricity and fertiliser use as key targets. “Diesel fuel use for the group is actually

For Rob Perchard, who runs 260 cows plus followers at La Ferme in St Martin and supplies milk to Jersey Dairy, it’s absolutely crucial that he manages his fragmented land block as effi ciently and sustainably as possible.“We own around 40 hectares with only 25 hectares based around the unit, but because of a benefi cial historical association with the Jersey Royal potato company we do have access to additional ground after their crop has been lifted in May,” he explains. “This allows us to sow maize on this ground and even the occasional crop of grass. But it does mean that our fi elds are spread around the island and that there are always going to be restrictions on our ability of be effi cient.”Fortunately, producers on Jersey have been able to import international pure Jersey bull semen since 2008 and this means the Perchards have been able to

good at 75 litres per herd, but a 10-litre reduction could unlock another £1,000 per cow. More regular maintenance of farm machinery, changing oil frequently, removing unnecessary weight and keeping types well infl ated and balanced will help kit to last longer and reduce fuel consumption.”On the other hand, the average electricity use within the group was high at 0.106kWh per litre. Cleaning light fi ttings, bulbs and fans so that they perform at optimum levels, can make a signifi cant difference and further reduce a unit’s carbon footprint.And the average nitrogen applied for the group was 120kg/ha. “The top 20% carbon performing units are around half that meaning that another £3,000 could be saved here through precision fertiliser application or the use of natural alternatives,” adds Ms Roberts. l

produce more milk from fewer cows.“During the past few years we have been able to increase output thanks to the use of better genetics. Previously we had been hitting a 5,000-litre annual herd average ceiling, but now the herd is yielding 6,300 litres and production is still rising. So as long as we have the quota available we are more effi cient than we were.”With both government and consumer support that values the Jersey cow heritage on the island – and therefore relative acceptance of a premium price for the high value milk he produces – Mr Perchard recognises he is in a stronger position than many mainland UK producers. However, in common with other producers on Jersey, his cost of production is high.“It’s more than 40ppl and this is largely due to our fragmented land base, as well as competition from the potato

and horticultural sectors that drives up rents. Most inputs have to be brought onto the island, which is also costly. “Our fi elds are also small and, invariably, a few miles apart and we have to cart water and slurry to pastures that are a signifi cant distance away. So any initiative that helps us to identify opportunities to be more effi cient has to be welcomed,” Mr Perchard adds.

A flyer brought home from school by his children five years ago was the start of Kendal-based producer James Robinson’s

journey to becoming a fully trained first responder. “It was asking for volunteers to join the local Endmoor and District First Responders and I thought it was a good idea, particularly in an area that’s large but sparsely populated. Knowing that such a group existed made me a feel a little bit safer, but I also saw it as an opportunity to learn some new – and life saving – skills and to give something back to the community.”So began the application process, followed by two months of training – just a few hours each week that he fitted in around his duties on his family’s 125-cow pedigree Dairy Shorthorn organic unit.“Basically it was an intensive first-aid course, plus a bit more. Our role is to respond to life-threatening medical emergencies that require an immediate response. In some more remote areas of Cumbria it can take paramedics a while to get to a patient. So our role is to be able to respond first and offer medical assistance while the paramedics are on their way. It’s very much about speed and saving lives.”James says that if someone has a cardiac arrest, every minute counts. “For each minute they go without help, their chance of survival falls by 10%. So those first few minutes really are crucial.” All first responders are equipped with a pager, which alerts them instantly to an emergency and its nature. “For example, it may say that there’s a 50-year-old female with left-side chest pain – signs of a possible heart attack. And we only need to press one button to say we’re on our way.”Equipped with oxygen and a defibrillator, James will drop everything and jump into his vehicle – particularly if it’s just minutes away. “If it’s at the other side of the area we cover and I’m in the middle of milking or calving a cow, I may press the ‘cannot attend’ button. There will be other first responders who are much closer to the casualty. If it’s close by, I’ll just go – the cows can wait if it’s a matter of life or death,” he says.James ‘responded’ more than 100 times in 2014 and has been on 50 ‘shouts’ so far this year. “It’s all voluntary and part of our role is also to fund raise for the service, which is part of the North West Ambulance Service,” he explains.Training is also on-going. It’s vital to stay up to date and there are also annual re-assessments too. That said, he said that anyone can use a defibrillator. “Don’t be afraid to use one if you think someone is having a cardiac arrest. They deliver verbal instructions and talk you through what you need to do. If someone is having a cardiac arrest and you do nothing then they will die. So don’t be afraid to have a go!”

The very best of both worlds

Being named runner up in Promar’s Milkminder Manager of the year

competition – and also being highly commended at this year’s Cream Awards – are the icing on the cake for producer Nick Sercombe. He’s farm manager at Knaptoft Hall Farm, near Lutterworth in Leicestershire, and is charged with looking after the Hall

family’s recently expanded herd. Nick’s wife, Louisa, has recently given up her job as a Promar farm business secretary to join him at the unit and will take on responsibility for calf rearing.“And I can’t wait – we’ve been waiting a long time for this. We’re fi nally realising our dream of managing a dairy business together,” she says.

The couple’s dream was to run their own herd, possibly on a county council holding. They’ve had a few cows of their own since 2005, mainly Jerseys and Holstein Friesians that they liked to show, which were run at Nick’s brother’s dairy unit near Melton Mowbray. Numbers had expanded to 60 by 2010 and by 2012 they had started to lose hope of fi nding a

tenancy. They’d decided to wait for just 12 more months and, if unable to secure one, to sell the herd.But then their luck turned in 2013. Louisa was contracted to carry out some farm secretarial work for Knaptoft Hall Farm and was told that the business was looking for a new manager. “So I mentioned it to Nick,” she says. “And he decided to apply. He beat 50 other applicants and got the job. It felt right – like it was meant to be.”That was in October 2013 and the good fortune continued – the couple were also able to take their cows with them. Neville Hall bought some of the Sercombe’s herd – they contributed to the herd’s expansion from 240 cows to today’s 300 head. “But we also kept ownership of some cows. It’s great to be able to continue with our pedigree prefi x, particularly because we enjoy showing and taking part in herd competitions. “And we also have the opportunity to manage them on one of the newest and best equipped unit’s in the UK,” explains Nick.

New facilitiesThe dairy unit is, indeed, brand new. A 50-point Dairymaster rotary parlour and sand-bedded cubicle housing for up to 500 cows was built on green land in 2014/2015. It replaces the 445-hectare farm’s existing and somewhat dilapidated facilities. The herd was moved to the new set up on

September 21, 2015. “It’s been extremely exciting and the cows were very quick to adapt to the new parlour,” says Nick.“I haven’t milked cows for eight years and I never really liked it,” adds Louise. “But milking in the rotary is a pleasure. There’s no stress – for the cows or the milkers – and it’s quiet and easy to operate.” The collecting yard has a backing gate with a scraper on it – Louisa says that this is a UK fi rst. And the cows are happy to come in to be milked: “They seem to enjoy a little trip on the roundabout!”It’s also quick. It was taking four hours to milk the herd through the old 24:12 herringbone parlour, but now it takes just 80 minutes. Nick had hand in the new site’s design and says that he’s always preferred rotary parlours, particularly for larger herds. “We have plans to increase cow numbers to 650 cows and the new parlour can easily handle a herd of that size. It is capable of milking 230 cows per hour. And the housing has also been designed and positioned so that it can be easily expanded when cow numbers increase.Yields increased when Nick took over the management of the herd – from around 7,000 litres to 9,000 litres, at 4.05% butterfat and 3.50% protein. “Individual cows are averaging 34 litres a day at the moment and we’ve certainly seen a few extra litres since moving to the new set up.”

Improved cow comfort has certainly made a difference, according to Louisa. “The old cubicles were built in the 1960s and they were so short that even I couldn’t lie down in them,” she says.The herd is calved all year round and managed – and split – into four groups: high and low yielders, freshly calved cows and heifers. “Come the spring, I think we’ll turn out the low yielding group and the far-off dry cows to grass, but the other groups will remain inside and fed a TMR. It gives us more control over their ration,” says Nick.

Free reinThe TMR comprises maize, wholecrop and grass silages plus a blend and provides the high yielding group with maintenance plus 30 litres. Individuals are topped up to yield with concentrates fed at a rate of 0.4kg/litre.With the free rein that Nick has to run the herd his way, and multimillion-pound facilities to do it with, it’s little wonder that he and Louisa no longer have a hankering to run their own unit. “In many ways we already are,” says Nick. “It’s just like having our own unit. I have daily meetings with Neville, but he trusts me to make key decisions. We also have a regular salary and fewer fi nancial worries than we would if this were our own business. We’re doing what we love – what more is there to say?” l

Falling average birth weight of Holstein heifer calves demands lower feed rates

Are you overfeeding your new borns?A study showing a decline in the average weight of heifer

Birth weights of Holstein calves have declined in recent years

F E E D I N G

The average birth weight of a Holstein heifer calf has fallen by 15kg during

the past three years, according to a study carried out by feed manufacturer ForFarmers. Figures show a drop in average birth weight from 51kg in 2012, to 36kg in 2015. There are several reasons behind the decline, which is due to changes in herd genetics. There is an

large variation in calf birth weights, with the study showing a range of between 26kg and 47kg on a single unit,” says Miss Kennerley. “Producers are, therefore, encouraged to treat calves as individuals and alter feed levels appropriately, rather than sticking to more general feeding plans.” The company’s study showed results for Holstein Heifer calves, but with more units looking at reducing cow size through genetics and cross breeding, one Cheshire-based unit is putting the information into practice with their Holstein Friesian cross-bred herd.Father-and-son partnership, David and Adam Challoner, run their 200-cow herd at New Pale Farm in Manley, Cheshire.The unit follows a twin block-calving system, with one group calving early, between January and April, and the second between August and October. The calving system was initially set up because it gave heifers a ‘second chance’ if they weren’t big enough to serve for 24-month-old calving. But the focus on heifer rearing during the past few years has helped to ensure that heifers are big enough to serve from 13.5 months of age, so they remain within their block, and avoid unnecessary costs by running into the next block and calving at 30 months old or older. The family has been working with Miss Kennerley on all aspects of heifer rearing since August 2013 and is seeing great progress following changes to the unit’s calf weighing and feeding regimes.

Accurate recordsAdam now weighs calves at birth to get an accurate record of weights. This is particularly important because the cross-bred calves on the unit are smaller at birth than a typical Holstein calf. There is also a large variation in birth weights due to the variety of different crosses

within the herd. By knowing the average birth weight, which is around 35kg, Miss Kennerley and Adam have been able to work together to tailor the calf diet to make sure the correct amount of milk is being fed. The aim of early feeding is to double birth weight by eight weeks of age and this equates to a daily live weight gain (DLWG) of 0.63kg.One of the most significant changes to the unit’s young stock management has been the introduction of milk replacer.

Individual feedingCalves were previously bucket fed with waste milk, but Adam now uses ForFarmers’ VitaMilk calf milk replacer, fed using a group teat feeder. “We split the calves into pens of six, according to their age and weight, and invested in teat feeders and a tub mixer,” he explains. “The powder is easy to handle and the teat feeders are a much simpler way to feed the calves. The group feeders also have individual compartments for each calf to ensure that the slower drinkers get all their milk, and the faster drinkers don’t get too much.”With the calves being smaller than a more typical black-and-white calf, they start on four litres per day of milk replacer based on their birth weight. “As the feed rate is quite low, it is fed at a higher concentration – 16% – to get as much energy into the calves as possible,” explains Miss Kennerley. The unit’s latest spring-born heifers are doing well and achieved an average DLWG of 0.78kg, which is slightly above target. And more than 90% of them achieved their target weight. “Our aim is for heifers to calve and enter the milking herd by 24 months old and to ensure that they are big enough to perform well,” explains Adam. “We feel we are achieving this with well-fed heifers, but are also doing so in the most cost effective way.” l

increased use of easy-calving sires and cross breeding, as well as rise in the use of sexed semen, which is leading to more heifers giving birth to heifers. All these factors are contributing to lower birth weights.And, in response to these findings, producers need to ensure they are reducing initial calf milk feeding rates accordingly. “The rule of thumb is to feed the equivalent of 5% of the calf’s body weight for the first 10 days of life, as this matches the capacity of the calf’s abomasum,” explains ForFarmers’ young stock specialist Rachael Kennerley, who led the study.“Failing to reduce the amount of milk fed per feed, based on lower birth weights, can result in overfeeding and this negatively impacts calf health due to excess milk spilling over from the abomasum into the rumen and can also compromise the calf’s longer term growth.“Once in the rumen, excess milk ferments and produces VFAs and lactic acid. These significantly reduce the calf’s rumen pH,” she explains.“This, in turn, can result in rumen acidosis, with scouring, bloat and reduced feed intake being just some of the short-term consequences. In the longer term, this over feeding can also result in calves suffering from impaired growth, inflammation of the stomach lining and increased susceptibility to illness.”

Feeding requirements The figures suggest that the average 36-kilogramme calf should be restricted to 1.8litre feeds from birth, compared to the 51-kilogramme calf that could safely consume 2.5-litre feeds just three years ago. These changes mean that extra care must be taken when feeding protocols are put in place.Ensuring that feed rates are right early on can also help avoid problems later with weaning. At weaning calves are traditionally grouped according to age, but if smaller and lighter calves have not been identified and fed appropriately early on, by weaning time they will be significantly behind their target weight and at increased risk of bullying from bigger calves. This will also result in low feed intakes and slower growth rates. For producers looking to maximise early growth rates and secure the long-term performance of their calves, it is vital to recognise this changing calf-weight trend and respond accordingly. “Even within individual units there can be a

Shropshire-based dairy producer and award-winning

columnist Roger Evans tells a shocking story of

vandalism that will drive even the most trusting

producers out to buy a few new padlocks.

A F E W W O R D S F R O M R O G E R E V A N S

Do you lock the door of your dairy every night? Of course you do. What about your medicine cabinet? Oh, that too? Well done. Or is

it only done when your farm assurance visit is due? When your farm assurance visit is due, do you have to dash off to your local supplier to buy two new padlocks because you use the two that you have so rarely that you can’t remember where they are? Although farm theft is apparently on the rise, most of us come from a background where we trusted that everything was fairly safe. But times change and we have had to move into a world that has to lock things up – and remove keys! That is because of straightforward theft. But have you ever thought about sabotage? I’ve heard about a couple of dairy herds that have been deliberately let out onto roads, but of most concern was the story I heard of a farm that had its dairy seriously trashed. As far as I know nothing was taken, but the damage was extensive. All the management records were destroyed beyond recognition, including all the service records. Who would do such a thing? Well you don’t have to look far to work that out, because the people responsible for the vandalism couldn’t resist leaving their calling card daubed on the dairy walls. ‘Milking cows is cruel’, or words to that effect, is the unmistakable calling card of vegans. Vegans intrigue me. If someone wants to adopt a vegan lifestyle I would not presume to have any problems with that. But for most vegans that does not suffice. They want everyone else to be vegan as well. There are countless letters published in both national and local newspapers about animal welfare, or the lack of it. And, if you read between the lines, they have a ‘vegan agenda’ behind them. The vegan concept is embraced with the sort of evangelical zeal that years and years ago, sent knights to the crusades and now, apparently, sends people to trash dairies on farms. There is a sort of adage that says that people support these causes because they haven’t got a proper life of their own. And you have to wonder if there is not an element of truth in that. But it seems that writing letters is just not enough for some and they have to stray into irresponsible and illegal activity. The implications for dairy producers are serious. What if they did break into your dairy and medicine cabinet? What if your afternoon milk was in the tank and they put some antibiotic in it? How would you know? You wouldn’t, would you? Well, not until the dairy gave you a ring the next day. Dairy producers have a tough life – it’s diffiuclt enough without crap milk prices – but I’ve never tried to come over as a victim. But it would be quite easy to think that life keeps chipping away at us. Whether it’s a reduced single farm payment or the coursers who are after my beloved hares, we mustn’t let the buggers beat us.

System (GPS) on farms in the Netherlands, France and the US and more recently on UK units. These units can see the effects of changes on parameters like growth rates, effi ciency and the economic costs of the heifer rearing programme.Estimates – or predictions – are based on the animal, environment and ration details. “It takes account of data such as body weight, condition, age as well as the season, ambient temperature and grazing topography, plus all dietary details from dry matter, energy, protein concentrations to vitamins and minerals and the feeding methods used,” explains Dr Quigley.“From this, the model can estimate intakes and total feed cost,” he adds. “It will predict growth and, by changing parameters, producers can see the effect on performance and profi tability of changes in feeding, management and factors including weaning and age at fi rst calving.”He says that using a model to predict rearing costs and monitor performance at each growth stage is giving heifer rearers the confi dence they need to alter rations and improve diets that will help to achieve their targets. “It can calculate the value of the heifers and make sure they are worth more than their rearing costs. And, even if it’s not this extreme, it may show that improving the diet and adding a small cost at some stage in the programme actually reduces the overall rearing period and total rearing costs. Most importantly producers can use it to identify gaps in their heifer-rearing programme and improve management.”

Growth ratesDevon-based producer Jack Elliot is modifying his calf diets and management in a quest to calve mature, well-grown heifers at 24 months old, or less. As part of this, he’s using Cargill’s GPS to help him achieve higher growth rates, particularly in the pre-weaning phase. “At the moment we’re calving heifers at 26 months old,” says Jack, who has increased cow numbers during the past fi ve years from 120 to 250 at Hunshaw Farm, Little Torrington. Output has increased too, with average yield standing at 10,500 litres on three- times-a-day milking. “Calving at between 22 and 24 months old will reduce rearing costs and free up space,” he adds. “But we need to make sure we’re achieving growth targets cost effectively.”

Cargill’s calf and heifer specialist Bianca Theeruth has used Jack’s data and management criteria in the GPS to predict the increase in growth rates that could be achieved by increasing milk replacer from the current 600g/day fed in two feeds from day three to fi ve weeks old, then halving rates and feeding once a day in week six prior to weaning. “The pre-weaning phase is the most effi cient for daily live-weight gain and we want to capitalise and make sure the gain is not lost post-weaning,” she says. “So we looked at the effect of increasing milk replacer under the same feeding system and maintaining starter feed to appetite and straw. The target on his unit is to double calf birth weights in 60 days and keep to a six-week weaning system. Achieving this, and by maintaining post weaning growth rates, Jack should see bulling heifers reach between 55% and 60% of their mature body weight at between 13 and 15 months old – about 375kg.”Using the GPS predictions and keeping other feeds the same, Jack has increased milk replacer feeding to 680g of powder for the fi rst fi ve weeks, then 340g in week six. The model predicts an increase in daily live weight gain from 590g a day to 620g.The model also predicts post weaning growth rates of 820g a day that gives an average rate of 720g a day during the fi rst three months of life. Progress so far has been good and Jack has seen actual growth rates match the predictions. “We’re not seeing any checks in growth at weaning either,” adds Jack. “After fi ve years of focussing on the milking herd, we’re now improving heifer rearing through more accurate feeding, monitoring – including regular weighing – and management.” l

‘Model’ heifer rearing can improve performance

‘Manage what you can measure’ is Jim Quigley’s mantra when

it comes to calf and heifer rearing. Cargill’s technical research manager says that it is impossible for producers to make a good job of heifer rearing with limited information.“Using the ‘eyeball’ method – for example just noting that ‘she looks big enough’ – might work sometimes, but it’s pretty hit and miss,” says Dr Quigley. “So often the extent of data recording on heifer rearing units is nothing more than a mark on the post, noting heifer heights.”He says that better heifer feeding and rearing protocols are the way forward. “This is key to improving dairy herd effi ciency. There’s too much money left on the table as a result of poor feeding and management decisions from birth until calving.”

Gene expressionJustifying his call for improved young stock rearing, Dr Quigley refers to data that shows that pre-weaning gain can alter gene expression. “Heifers will produce more milk in their fi rst lactation and work has shown that every kilogramme of average pre-weaning daily weight gain resulted in an extra 850kg of milk in the heifer’s fi rst lactation. “Age at fi rst calving, rearing costs and fi rst lactation yield are all good indications of heifer rearing effi ciency,” he adds. “For example, trials have shown that heifers should achieve 75% or more of the milk yield of mature cows in the herd. We also know that small heifers eat less, produce less milk and leave the herd earlier. “And fi rst lactation and lifetime milk production are optimised in heifers calving at between 22 and 24 months old. Heifers calving outside this range are associated with higher rearing costs, health problems, increased culling and lower lifetime profi t.”Dr Quigley acknowledges that achieving the optimum age at fi rst calving is management intensive. “But if producers take advantage of defi ned targets and monitor progress they can see where they’re going. And using models to simulate the growth of young stock – from birth through to calving – will mean that they can see the impact that changes in management might have on their rearing system”Cargill is already seeing the benefi ts of its Calf and Heifer Growth Prediction

Protect heifers from liver fl uke to optimise age at fi rst calving

Protect your investment

More producers should be checking to see if cattle parasites

pose a potential threat to the effi ciency and profi tability of their herd. Liver fl uke infestation, in particular, can impact on heifer growth rates, as well as fertility. And mature cows can

also experience a reduction in milk yield and fertility – both of which can make a serious dent in the business’ bottom line, if they’re infected with liver fl uke.Bulk milk antibody tests (ELISA) performed by NML during the past 12 months have identifi ed that, of the

samples taken, 43% of herds have been exposed to liver fl uke. And, with liver fl uke reported to cost the agricultural industry £300 million a year and having an economically signifi cant effect on milk yields, managing the infection in young stock could have signifi cant benefi ts to long-term dairy herd performance.So, what is ‘best practice’ advice on preventing liver fl uke in young stock – and treating any infected cattle – to help reduce the associated costs of the disease and maximise margins?“The key here is to achieve good levels of fl uke control in young stock, so they enter the milking herd free of infection,” says vet Andy Forbes, who is Honorary Professor at the University of Glasgow’s

Preventing and controlling liver fl uke in young stock will not

only safeguard heifer growth and fertility, but can also serve

to protect milking herd productivity. We spoke to one of the

UK’s leading cattle vets to fi nd out more.

costly – effect on fertility. And it’s no longer a parasite that’s confi ned to the wetter parts of the UK. Even the drier eastern regions are seeing cases of the disease. Producers are advised to monitor their herds for liver fl uke, by testing bulk milk for antibody levels and then, if levels are of concern, by looking for liver fl uke eggs in cow faeces.

Milk withdrawalDr Forbes says that if treatment is necessary, as is increasingly the case and even in areas that were traditionally too dry to allow the host snails to survive and thrive, then it can be diffi cult due to the required milk withdrawal following treatment. “One option is to administer fl ukicide routinely at drying off. But it’s not ideal. Treating the entire herd at the same time is preferable because this can have a substantial effect on the amount of larvae and eggs shed onto pasture and can help to control the parasite more effectively. But the ‘drying off’ dose does offer individual animals some protection. As does preventing animals from grazing in, and close to, known wet areas where the snail hosts live.”Monitoring heifers for signs of the parasite and treating accordingly will play a signifi cant role in preventing a liver fl uke problem in the milking herd later on. “Young stock are often grazed on ‘rougher’, wetter pasture – grassland that would be readily poached by larger milking cows. And yet it’s here that they could be more likely to come into contact with the snail host and ingest larvae,” says Dr Forbes.“Think about where heifers are grazed, with a view to preventing infestation.” Signs of liver fl uke in heifers include a decline in expected growth rates and perhaps a reduced conception to fi rst service rate. “Mature fl uke migrate to the liver and can cause signifi cant damage. Because the liver regulates the heifers’ hormonal balance, fertility can be compromised.”If you think your heifers may have a liver fl uke problem, he suggested a bulk milk ELISA test on the milking herd fi rst: “If it’s not in the milking herd then it’s unlikely to be in the young stock, so that’s a good starting point.“If the bulk milk test is positive and antibody levels are signifi cant, a faecal egg count in the milking herd can further gauge the level of infestation and help determine the need for treatment. A faecal egg count test can be also be used to test heifers.

“It’s vital to assess the heifers and treat them periodically – as and when necessary rather than routinely – to minimise the use of fl ukicides. The good news is that, when treating heifers, there’s no milk to withhold so they can be treated as a group and this offers better control of the parasite.“Liver fl uke infection can increase heifer age at puberty – a recently study showed a typical delay of at least a month. This can lead to later fi rst service and push up the cost of rearing replacements. “This can be felt particularly keenly in block-calving herds, where a delay in calving can signifi cantly disrupt a tight – and effi cient – calving pattern.“For some herd, tackling the problem at heifer level will be suffi cient to achieve good control. For others, routinely using a fl ukicide at drying off may be the best approach, but it won’t necessarily have an impact on pasture contamination and re-infestation,” says Dr Forbes.

Spring-calving ‘advantage’“Spring-calving herds have an advantage here. The whole herd can be treated at drying off – typically around Christmas time – and because they’re all treated at once and usually housed then there’s only a small chance of them picking up a new infection. And there will be no eggs being passed out in the dung when they go out to pasture in the spring.”Due to the complicated lifecycle of liver fl uke and the issues surrounding milk withholding periods, Dr Forbes recommends that, if producers think they have a problem, they should talk to their vet for advice on how to best prevent and control it in their herd. “This will not only safeguard heifer growth and milking cow productivity – and overall herd fertility – but it will also make sure that any fl ukicide treatments are both appropriate and effective.” l

School of Veterinary Medicine and also a technical representative of the industry stewardship organisation COWS (Control of Cattle Worms). This is an industry-led steering group, which promotes sustainable control strategies for managing cattle parasites.“Not only will controlling liver fl uke in heifers help to ensure that the milking herd’s performance is not affected by the disease, it also avoids the issue of managing fl ukicide milk withdrawal periods,” he explains. There are currently no zero-milk-withdrawal period products licenced for use on dairy cows, so controlling the parasite in lactating animals can be tricky.A typical sign of liver fl uke is a drop in milk yield. It may only be a slight decrease in some instances, but liver fl uke costs the UK dairy industry £5.8m each year in lost production alone. And as its name suggests, liver fl uke can also cause severe damage to the cow’s liver and this can also have a knock on – and

New kit and initiatives to help producers meet heifer growth targets

Maximise calf potentialWith such a glut of products and programmes, all designed to improve the effi ciency of calf

and heifer rearing, realising a 24-month target calving age should be in reach for all producers.

We highlight a few of the latest innovations.

Initiative keeps calf growth on track XLVets has launched an initiative designed to help producers check that calf growth rates, during the fi rst eight weeks of life, are on track to ensure that they calve down, as heifers, at the target age of between 22 and 24 months old. Called Calf Tracker, it is based on measuring and monitoring fi ve key performance indicators: growth rate to weaning, total mortality, pneumonia rate, scour rate, and total protein level in the blood.“To maximise lifetime production, the optimum age for fi rst calving is between 22 and 24 months. Calculating back, this means that heifer calves need to average growth rates of between 850g and 1kg per day, so that they can be served at between 13 and 15 months old. At this point they need to have reached 60% of their adult bodyweight,” explains Westmorland Veterinary Group’s Kirsty Ranson, heads up the XLVets steering group on the initiative.

“So a calf’s growth rate in the fi rst eight weeks of life has a massive impact on its future performance.”She adds that the aim of the initiative is to help producers to accelerate growth rates in young calves: “And to enjoy the benefi ts of getting heifers in-calf sooner. This not only reduces rearing costs, but also means fi nancial returns will be gained sooner.” Producers can access the initiative through their local XLVets’ vet practice and they will receive a starter pack to support their monitoring activities. This

includes a weigh band for measuring calves and a guidance sheet on how to calculate weights. “By monitoring growth rates, producers and their vets can see whether calf performance is on track or whether investigations are needed into aspects of health and management to improve it. Poor growth could be the result of underfeed milk powder, disease, or cold weather,” says Miss Ranson. “Another aspect to be assessed is how well antibodies are being transferred from the colostrum and conferring immunity to the calf. Vets will be taking blood samples from calves in their fi rst week of life and measuring the total protein level. They will look at the average as well as the variation, because these fi gures will fl ag up whether changes to colostrum management and feeding are needed.“And with more than 40 XLVets practices offering the scheme, we will be compiling the data so that calf performance can be benchmarked within a practice, and also across our practices nationwide.”

Cold-weather pointers to maintain daily live-weight gain• Make sure every calf receives adequate quality colostrum• Step up energy intake – by increasing the amount of milk offered per

day. Increasing the oil content of the milk replacer from 16% to 20% has a negligible effect on daily energy intake

• Increase the level of milk solids by 100g per day for every 10°C temperature drop below 20°C to maintain growth rates.

• Reduce cold drafts and maintaining adequate ventilation. • Install a system to drain moisture, where neccessary• Ensure bedding is kept clean and dry and provide plenty of deep

straw bedding – it provides insulation and reduces body heat loss• Use calf jackets • Provide an external heat source close to calves

Tool kit to maximise heifer potential

Heatwave is forecast to increase growth rates

A programme designed to help producers ‘grow’ more profi table cows has been launched by Volac. Called Feed For Growth, it features a ‘road map’, accompanying calculator and comprehensive set of technical guides.Feed For Growth allows producers to really focus on young stock management – from day one – to help ensure that heifer replacements calve between 23 and 25 months of age. This is the optimum age, according to Royal Veterinary College research fi ndings, that concluded that cattle lived longer, had fewer problems in later life and subsequently produced more milk per day throughout their life compared with heifers that calved at a later age.The programme enables producers to create their own heifer rearing ‘road map’, which sets individual unit objectives and helps producers to track performance and continually review it. This allows then to check

Winner of the RABDF Livestock and Machinery Innovation award, at this year’s Livestock Event, the Pyon Products’ Heatwave Milkwarmer can feed up tot 30 calves and, according to the manufacturer, offers many benefi ts over cold milk feeding. Not least are higher daily live weight gains and healthier stock, since warm milk is digested more effi cienctly. The company also claims that it’s hygienic, because the milk is stored cold – saves time and also reduces waste. The system allows just one bulk reservoir of cold milk to be prepared each day. The milk is then heated just before being delivered to the teat, allowing the calf to access warm milk on multiple occasions during the day. This unique ‘once a day’ system makes milk available all day.Not only will dairy heifers benefi t, but bull calves will also develop faster, and can be ready for market a week earlier, according to the manufacturer. The system is available from Wynnstay and costs £385 plus VAT.

that each animal is on target to reach puberty by nine months old, fi rst service at between 13 and 14 months old and conception by 15 months of age. An on-line calculator sets growth targets and the level of feed required, while back up technical information offers advice on all three external infl uencing performance factors – environment, health and nutrition.“Producers spend 20% of their total

annual farm investment on rearing replacements. But 22.5% of live-born heifers fail to make their fi rst lactation and for the remainder ‘breakeven’ is not achieved until at least the middle of their second lactation,” says Volac’s Jackie Bradley. “This ‘tool kit’ will enable producers to better understand, plan, manage and review, and ultimately maximise their herd’s untapped potential.”




Are you ready for winter?Volac is reminding producers that falling temperatures mean that calves may require more milk in order to maintain growth rates and immune function. To achieve targeted performance they will require additional feed and management.Calves can grow at an average 0.8kg per day in their fi rst few weeks under normal conditions if fed suffi cient levels of milk – 900g of milk solids, alongside dry feed and water, that’s when the environmental temperature

ranges between 15°C and 25°C, what’s termed the thermoneutral zone.During the fi rst three weeks of life and when temperatures plummet to less than 15°C, they’ll start using energy from feed to keep warm. High risk calves – those that experienced a diffi cult birth and twins – are more vulnerable and will feel cold at higher temperatures. In fact daily energy requirements increase by up to 30% once the temperature drops below freezing. By their fourth week, they’ll be more robust and won’t feel the cold until

about 0°C. However, high moisture levels and draughts will dramatically increase their susceptibility to cold stress. Draughts of just 5mph will make calves feel between 8°C and 10°C colder.Cold stress results in energy being diverted from growth to maintaining body temperature. Consequently growth rates will fall and the calf will become more susceptible to disease, such as respiratory infections and scours, because less energy is also available for immune function.

Milk replacer supports health and performanceA calf milk replacer, which the manufacturer claims will help to ensure that calves get off to the best possible start, is now available from Wynnstay.Turbo Start has been formulated to comply with the ‘life start’ concept, which is based on on-going research into how to get calves growing quickly and healthily. Alongside specifi c management protocols, this milk can help producers to rear profi table animals that are set to calve at between 22 and 24 months old.The product is a highly digestible whey-based milk powder with added oils to supply energy. This milk powder also has the additional benefi ts of high levels of vitamin E,

to support immune function, along with Greenline, which is a synergetic blend of ingredients designed to support optimum health and animal performance.The milk can be fed via bucket, teat or computerised machine. Typical recommended intakes would be a minimum of 900g/head/day. Designed to be fed as part of an accelerated growth feeding programme with a delicately balanced amino acid profi le, the company says that this milk allows producers to feed at higher rates without digestive upset. It adds that Jersey calves, in particular, will thrive from higher protein levels, making the milk replacer the perfect choice for anybody looking to unleash the genetic potential of their future herd.

Running a tight ship relies on smart monitoring tools

Caught by the collar

S ilent Herdsman has been a significant investment for Richard Blackburn

but he is adamant that it’s easily paying for itself. During the past seven years he has doubled cow numbers to 400 Holstein Friesians. He’s also built new cubicle housing and taken on a management system that records cow movement, eating and rumination data through collars and a wireless aerial linked to his PC and mobile phone. More cows called for accurate monitoring and recording. Working closely with his vet, Den Leonard of Lambert Leonard and May, he identified health and fertility as the key target areas to concentrate on. Starting with fertility, and recognising

there was progress to be made, Richard swapped his old fertility monitoring system for Silent Herdsman. “We were increasing cow numbers and needed more collars so it was an obvious time to go for a more up-to-date and reliable system,” says Richard.He also joined the vet practice’s Vet-Synch fertility management programme, which involves the vet monitoring and synchronising the non-pregnant cows every week from 45 days post calving. Two years on and Richard is reaping the rewards, not least from Silent Herdsman. The frequent data updates, thanks to an aerial strategically placed in the yard, means that he and his team are now working with more accurate and reliable

information than they were in the past. “It’s improved our heifer management too,” he adds. “We have an aerial in the heifer yard and collars are put on when they are 13 months old so we can pick up heats from movement data as well as observation. We don’t intervene and induce heats, but we still want to calve them at 24 months old. Heifers are served with sexed semen and the timing of insemination is highly important. The collars have been a huge help.”The NMR data provides tangible evidence too, with most of the herd’s results now within the top 25% of NMR herds. With a fall in calving interval from 430 days to 380 days as shown in Figure 1, the latest data shows that 81% of cows are served within 80 days of calving and 51% of the cows are in calf 100 days post calving. Average calving to conception is 115 days and conception rates have increased from 23% to 42% during the past two years, since Silent Herdsman has been in operation.

Work ‘by the screen’Some of the credit, though, goes to Richard and his assistant Graham

Latest Health AlertThe new mySilent Herdsman Health Alert software service provides early identification of animal illness through 24/7 eating and rumination monitoring. It has been proven to accurately and reliably alert producers to the signs of illness – most typically the early onset of acidosis, ketosis, mastitis and lameness. Early indications of health problems mean that preventative action can be taken. All Silent Herdsman collars can provide eating and rumination data and alerts can be accessed through an annual licence fee, which costs £1200 for a for a 200-cow herd.

Cost:benefitCatching a potential case of clinical mastitis early by using mySilent Herdsman Health Alert can result in significant savings. “A ‘typical’ case of mastitis, based on the frequency and severity of the different types of mastitis, costs between £200 to £250,” says dairy vet Den Leonard. “A 10% reduction in mastitis rate in a 100-cow herd is, therefore, worth between £2,000 and £2,500. For a herd of 400 cows, this is between £8,000 and £10,000.”Early notification of ‘vulnerable’ cows gives producers the opportunity to intervene with a holistic treatment at a fraction of the cost of treating a mastitis case.

Routledge. They do all the AI work ‘by the screen’, picking up heats off the PC or their mobile phones and then inseminating cows at the optimum time. In addition, the whole farm team plays a part in heat detection and herd health by being vigilant and observing cows at every opportunity.And more benefits are achieved through the latest Silent Herdsman development. In January 2015 Richard upgraded to mySilent Herdsman Health Alert, so he now monitors eating and rumination patterns and receives alerts on his farm PC and phone. The combination of rumination and

eating is an indicator of a cow’s well-being – a change from the normal pattern can signify the onset of illness. “We can see her eating and rumination patterns and often there’s no need to panic if one or the other dip a bit, but when they’re both down then that’s the time to pay very close attention,” says Richard.“Cows are highlighted on the screen with a ‘health alert’ flag and we might then mark her and keep an eye on her for 24 hours,” adds Richard. “But so far we’ve found that it’s a pretty sure sign that she’s going down with an udder infection that, without early

intervention, could develop into a case of mastitis. Often the health alert confirms our suspicions.” Richard and his team have also noticed a strong correlation between decreased rumination time and bulling activity. “If she’s meant to be bulling and I see her rumination has fallen I can be pretty sure she’s ready for serving.”

Early warning systemWhile he knows that good stockmanship is important and Silent Herdsman won’t manage herd fertility and health single-handedly, he is finding the Health Alert features to be a reliable early warning system. “As the herd has grown, our pool of skilled labour is stretched more thinly,” adds Richard. “I’m aiming for 9,000 litres of milk on twice-a-day milking and I want to make sure I have a herd of healthy, fertile and long-lasting cows,” he says, adding that he’s already taking control of some key diseases. All calves are tagged using XLVets’ CheckTag BVD tags and the farm is now BVD free, and NMR’s Herdwise Johne’s testing is used. “There’s always scope to be better and more efficient. So if Health Alerts picks up subtle behavioural changes that might be easily missed in our larger herd and we can take preventative action then our efficiency will improve.” l

Smart tool for heat detection

Young bulls from the US

Ovalert ensures efficient and effective automatic heat detection with 90% accuracy and predicts the optimum timing for insemination to help reduce calving intervals and insemination costs. Integrated health monitoring, with timely alerts to possible problems, will enable better herd management.The Ovalert’s user-friendly interface has standard features that highlight individual cow’s data.

Five behavioursThere are 24/7 activity monitors, which are available as leg pedometers for standing and lying or neck tags for eating.The leg responder identifies five specific behavioural aspects, which provide a representative picture of a cow’s daily behaviour pattern, including time spent lying down, standing, walking and the number of times she stands up and how many steps she takes.

Grazing monitoring via the neck tag will be the best choice for a grazing herd, where the heat specific behaviour of neck movements is measured.Accurate data is recorded and transmitted every five minutes and is analysed every 15 minutes – that’s 96 times in 24 hours.

Web-based programThis information can be accessed by the producer whenever they log in to the system and, being a web-based program, the data is also accessible through smart phones, tablets and laptops. A unique feature is that the CRV SireMatch mating program is available through Ovalert.For full details of the Ovalert system contact CRV Avoncroft or your local CRV Avoncroft representative.

Helping producers plan winter rationsWith summer over and low milk prices looking set to stay into next year, now is the time for producers to plan their strategy for the winter months, in order to ensure that they maximise herd performance. To help with this planning process, ForFarmers has launched its Dairy Triple F assessment scheme, which is a simple, paper-based guide that examines basic fi nances, feed costs, utilisation and forage availability on customer farms.“It provides an ideal opportunity to review key business areas before producers decide on their objectives for the coming months,” said ForFarmers’ ruminant product manager Nick Berni.The assessment looks at farm performance in the areas of milk yield and quality, feed rates, feed costs, calving patterns, forage quality and ration composition. “The information gathered from the Dairy Triple F assessment is used to benchmark performance against other,

Triple F looks at key measures on dairy units

ForFarmers hosted a series of conferences in September and October to promote effi cient young stock rearing in the UK. Three regional events – in Cheshire, Lancashire and Ayrshire – saw more than 200 producers listen to advice on making the right choices when it comes to heifer rearing. Heading into what will, undoubtedly, be a tough winter for producers, one of the main talking points at the conference was looking at the different choices regarding heifer rearing systems, and the opportunities to save money without impacting future herd

Conference speaker Peter van ’t Veld, from Denkavit NL

Conferences focus on improving heifer rearing

North America’s soya stocks are still high and with the new crop 80% harvested, we should see some harvest pressure through November. As a result, soya forward cover during the coming month should be attractive. Rapemeal is less attractive than soya, because the oil value is low and the crush margin poor. So spot buying of rapemeal is the best approach, says ForFarmers’ Colin Shepherd.Distillers’ grains are a different matter, with Ensus shut down and Vivergo about sold out, UK produced ethanol wheat distillers’ grains are in short supply. “So consider US maize distillers’ now, as they are a cost effective alternative at around £25/tonne less than rapemeal. With the extra energy they look like a good buy. However, sales of US distillers’ have been strong and availability will get tighter, so expect a rise during the next month,” says Mr Shepherd.Strong candidates to help solve some of the protein puzzle for this winter should come from Promaize (high protein molasses), wheat syrups or brewers’ grains.After a third consecutive record crop, the world has plenty of wheat. There’s a bearish outlook, but the market is watching current dry weather in Australia, Black Sea and parts of the US. Plantings in Russia and Ukraine have progressed well, but the lack of water seems to have affected tillering ahead of the winter period and this will limit yield.“A surprise increase to the US maize yield means that, during the course of November, we should see more maize become available. “If you’re looking for forward cover on cereals look at maize now. There are some interesting offers worth considering,” says Mr Shepherd.

Speakers included Denkavit NL’s Peter van ’t Veld and Dairy Consultancy’s Owen Atkinson, as well as Rachael Kennerley and Lindsay Reynolds from ForFarmers UK. The topics covered at each conference included caring for young calves and making choices between calf milk replacer and whole milk, successful heifer rearing based on results from the recent Welsh Dairy Youngstock Project, and how to rear your heifers in the most cost effective way.

Breeding cows that last is essential to dairy business sustainability

Taking the long view

The longevity or life span of a dairy cow determines how many productive

lactations she completes within a herd – and how happy a producer is to have her in the milking herd. “Many traits will determine a culling policy, such as production, fertility, health and workability,” says CRV Avoncroft’s David Matthews. “Replacement may be based on unsatisfactory production – voluntary culling – or other issues, mastitis, fertility or hoof problems – involuntary culling. But, in practice, replacement is seldom due to only one of these two.” A 100-tonne cow study, carried out by CRV, revealed that sires’ breeding values are crucial in achieving high lifetime production, NVI, longevity, udder health and conformation.

“All 100-tonne cows show certain traits,” adds Mr Matthews. “They are quick off the blocks and, in fact, they often show a strong increase in production that continues until their fifth lactation.“Good legs and feet are more important than udders and both udder shape and udder health help to determine the longevity of the cow.” He says that, with slightly above average volume or capacity, they will quickly reach the 100-tonne goal: “And good functional traits enable them to live a long and healthy life. Their lifetime production and longevity are two components that are inextricably linked, with equal influence. So a high average daily yield and good longevity will result in a higher final life-time production.”

The research clearly demonstrated that bulls’ breeding values for the crucial components are the deciding factor in high lifetime production. “So producers who breed consistently for the main breeding values – such as NVI, longevity, udder health and legs – will establish those traits in their herds. “Legs, in particular, are noted among the conformation components because these are the most important factor in promoting longevity.”The Dutch breeding value for longevity is a figure that indicates how satisfactory the daughters of a certain bull perform. It is a measure to rank bulls for the ability of their daughters to avoid culling. “By using the highest longevity bulls, cows will remain longer in production,” stresses Mr Matthews.

Sustainable futureAfter 11 years of managing the herd at Manor Farm, near Cheltenham in Gloucestershire, Rob Richmond believes he is on track to maximise the unit’s potential. A major overhaul of the business has seen the farm convert to organic, introduce all year grazing, change calving pattern and adopt a

specific breeding policy to produce cows that are built for longevity. When Rob first arrived at the unit, it carried a 100-cow autumn-calving British Friesian herd and relied heavily on contractors for land work. However what you find today is a completely different business. Significant changes to the management system have been made with Rob focussing on efficiency and the sustainability of the business. Today’s herd numbers 210 cows, managed on a spring-calving organic system and most of the land is utilised for grassland. The herd is outside all year and with that move have come some major changes in its breeding policy. “Each farm is different,” explains Rob. “You need to consider the resources you have available, know where you want to take the business in the future and find a system that complements them both.“I firmly believe in sustainability, in terms of cows and land,” he explains. “I wanted the farm to have a long-term future and, as a result, I’ve worked hard to improve the soil, the grassland and the cows.”

Robust cowsWith the aim of improving soils, and the introduction of herbal leys and mob grazing, Rob soon realised that he needed a specific type of cow for this system. “You need a robust cow, with good feet and legs, that is easy to care for and has the capacity to maximise intakes of grass,” he says. “I felt I needed to look to New Zealand for genetics as this is a farming system they excel in. “Around four years ago, I started to use New Zealand bulls from CRV Avoncroft.

Table 1: CRV Avoncroft’s top sires for longevity

I then started using CRV Ambreed bulls from CRV Avoncroft, particularly Pascal and Philosopher.“The index used for these bulls didn’t focus strongly on production, as so many countries’ indexes do, but considered the management and conformation traits needed for a long-life cow. To me, this is back to basics – common-sense genetics for milk from grass.“Our system is based on producing milk from grass and our management aims to do this efficiently. That’s why we’ve changed the calving pattern to spring calving, as this maximises the use of the grassland.”

The herd is averaging 6,000 litres, at 3.8% fat and 3.4% protein, using less than a tonne of concentrate fed through in the parlour. “We sell milk to Organic Milk Suppliers Co-operative on a liquid contract, so milk constituents are not a big factor in our breeding policy. Our cell count is 150,000cells/ml, which I think reflects that they’re not at all stressed.”

Farm efficiency“This will ultimately increase longevity,” he says. “This is a cost to a dairy business that I feel is often neglected. However, the financial implications of a cow’s life and, therefore productivity, is significant. Replacements are a huge expense to a dairy business. Every extra lactation per cow will increase farm efficiency and, therefore, profitability. “I really feel the business is in an exciting place,” he adds. “All the changes that have been made are now coming together. The pastures have improved and the capacity of the cows and their ability to convert their intakes to milk has increased. “Since I’ve been here, I’ve seen yields increase by 10% while the use of concentrates has reduced by a third. I have a milk buyer that is going from strength to strength and fully supports my farming system. “And young stock are showing great potential for capacity and strength. I am looking forward to a great future with this herd.” l

Breeding for longevity and tackling the causes of involuntary culling are key, so steps include:• Lowering the replacement rate and rearing fewer calves (lower costs)• Tackle problems including fertility, lameness and mastitis • Focus on functional conformation – particularly feet and legs, and udders• Use SiryX/beef bulls for best/worst heifers/cows• Increase the average age of cows• Making use of the durability breeding goal in CRV’s SireMatch mating program

The squeeze on milk prices has curtailed and postponed investment

on many dairy farms. But if spending money on your unit could, ultimately, reduce costs and improve effi ciency, then it will be well spent. Belts remain pulled tight for many dairy businesses but, as in all times of austerity, there are fi nancial gains to be had if you’re looking to invest.Because few dairy businesses are spending money, the allied industries are feeling the pinch too. They’ll be glad of your business and that puts you – the potential customer – in a strong position to negotiate a good deal if you do want to invest – be that in steel and concrete, such as improving cow housing or milking facilities, or, perhaps drainage.

Business planBut before you even consider dipping into business capital or negotiating borrowings, it’s absolutely vital to have a detailed – and honest – look at your position.If you’re planning on staying in dairying long term and you’re optimistic about the future, that’s a good basis. But you also have to make sure that you’re investing in a sound business and that you have a strong business plan.By this he means that you’ve convinced both yourself and an independent adviser – be they a consultant or the bank manager – that the investment will reduce your cost per litre and improve profi tability.Now is not the time for vanity projects or keeping up with the neighbours. And it’s not about increasing output – it’s about increasing effi ciency and profi tability, particularly in the current climate. It’s very much about identifying the limiting factors, or ‘bottlenecks’, on your unit. Dilapidated cow housing can reduce herd effi ciency, particularly if investing

in new cubicles will reduce mastitis and lameness. New housing may also offer easier access to feed and water troughs and improve cow effi ciency. And it may also save on labour, if it takes less time to scrape out. Bedding costs may also be reduced. All these factors must be costed out.

‘Sense’ checkA starting point is to analyse where the business is now – so benchmarking is vital. Look at your costs and identify what’s costing more than average and what’s about right. And then compile a budget of where you want to get to. Then do a ‘sense check’ – if your labour cost is 7ppl and you want to get it down to 6ppl, is new cow housing really the answer? Factor in other labour costs, such as calf rearing and relief milking. Look closely at what that labour cost comprises and see if there are other ways to reduce it – without compromise and perhaps with little or no investment. It’s vital to mull things over and look at all your options.Perhaps this spring you were unable to get your cows out to graze early grass – remember grass is the cheapest feed available – because the land was too wet and access was diffi cult. This may be one of your unit’s ‘bottlenecks’ and perhaps investing in drainage and cow tracks could be easily off set by being able to access grazing earlier in the season, particularly if you typically run short of conserved forage and are forced to buy in feed.Investing in steel and concrete could be the answer, or it could just be an expensive luxury that will add further strain to your business’ fi nances. So ask yourself, is it going to improve my bottom line? And, if not, do we really need it?

Upgrading facilities can make sense – even in a tough economic climate

Investment opportunities?

By the pasteurization of the milk over 95% of the pathogenic germs are killed. Dangerous pathogens such as E coli, staphylococci, enterococci, etc. are reliably killed with this method. The milk protein is denatured only slightly, the vitamins are preserved almost completely.Pasteurizing the milk is thus an effective method to utilize the milk of cows with udder problems in calf breeding, without causing an increased risk from diarrhoea. This also allows the use of non-marketable milk as a valuable feed for calves. Features:• Agitator permanently mounted on the lid• Thermostatically controlled heater 8,4 kW• Outlet disc valve NW 50• Control board with electronic thermostat• Controls with pasteurizer program and keeping warm program• Delayed start of the program possible• Sensor sits in the milk• Digital display of the milk temperature• Heating and cooling possible
