MANAGEMENT IN BROODING

PREPARATION FOR CHICK ARRIVAL Litter material should be spread evenly to a

depth of 3 –4 in (7.5–10cm) and t hen l evel l ed ddd ddddddddd dd ddd br oodi ng ar ea.

The necessar y equi pment must be assembl ed i n t he appropriate configuration as-

Feeder- 30 inch long/ 50 chicksWaterer- 2 litre capacity/ 50 chicks

/

PREPARATION FOR CHICK ARRIVAL Equipment in the house (i.e., fe

eders, drinkers, heaters and fan s) should be arranged to allow c

hicks to maintain body temperat ure without dehydration and to find feed and water easily.

Configuration will depend on th e brooding system and on other

equipment being used.

PREPARATION FOR CHICK ARRIVAL

Supplementary feeders and drinkers shouldbe pla ced in close proximity to t

he main systems.

PREPARATION FOR CHICK ARRIVAL - Houses should be pre heated fo

r a sufficient period to achieve t arget house and litter temperat

ures prior to chick arrival. Temperature should be monitor

ed regularly to ensure a uniform environment exists througho

ut the whole brooding area.

AFTER ARRIVALFirstly provide lukeworm water for 2-3 hrs then provide following solution-Glucose-50gm/ litreMultivitamine-1gm/4 litreElectrolytes- 1gm/ 2 litre

Provide instant energy and restore normal body function.

Note: feed should be supply after 3 hrs on arrival to avoid early enteritis in chicks

FEEDER MANAGEMENTFeeder should keep neat & clean.To treat feeder by disinfactant regularly.

Keep appropriate no. of feeder on basis of population

Provide 24 hrs pure water at daily basis

Use acidifier to control E. coli & salmonella in water.

FEEDER MANAGEMENT

LITTER MANAGEMENTIn winter season litter should be 2-3 inch & for winter season 4-5 inch depth

Daily spray with disinfactantMoisture level should be keep in minimum level

Moist litter should dry sun heat &treat with surface agnt.

VENTILATION Air quality is critical during the br

ooding period.Ventilation is required during the

brooding period to maintain temperatures at the targeted level and

to allow sufficient air exchange to prevent the accumulation of har

mful gases such as carbon monox ide, carbon dioxide and ammonia.

VENTILATION Establishing minimum ventil

ation rates from one day of a ge will ensure fresh air is sup

plied to chicks at frequent, re gular intervals.

Stirring fans can be used to maintain evenness of air qua

lity at chick level.

MONITORING EARLY CHICK PERFORMANCE

MONITORING EARLY CHICK PERFORMANCE As a result of continued g

enetic gains in growth rat e, brooding has become a

n increasingly greater pro portion of the life of the fl

ock. In addition,

MONITORING EARLY CHICK PERFORMANCES - even day body weight is highl

y correlated to market age weight.

It is strongly recommended that a sample of each flock be weig

hed at seven days to evaluate g rowth performance against stan dards for the given product.

MONITORING EARLY CHICK PERFORMANCE Scales used should be capable of

weighing in 1 g increments. Minimum sample size should be

1 percent of the flock, With sampling done in at least th

ree separate areas of the house. Refer to the attachments for prod

uct weight objectives.

MONITORING EARLY CHICK PERFORMANCEA general rule of thumb woul

d be a - seven day target of 4xdayold chick weight.

Average weights below 130 g should dddd dd dddddddddddd n as to causative reasons.

Seven days weight below 1g release 6g at 42 days.

HUMIDITYdddddddd ddd ddddd ddd d dd ddd

hatcher, at the end of the incubation process will be high (

approx. 80 percent). Houses d ddd whole house he

atingd dddddddddd d dddd dddddd drinkers are used, can have R

H levels as low as 25 percent.

HUMIDITYHouses with more conventi

onal equipment (i.e., spot brooders, which produce mois

ture as a byproduct of comb ustion and bell drinkers, whi

ch have open water surface s) have a much higher RH (u

sually over 50 percent ).

HUMIDITY To limit the shock to the

chicks of transfer from th e incubator,

RH levels in the first thre e days should be maintai

ned near 70 percent.

HUMIDITY RH within the broiler house should be

monitored daily. If it falls below 50 percent in the first

week, chicks will begin to dehydrate ,C ausing negative effects on perform

ance. In such cases, action should be take

n to increase RH.

HUMIDITY -If the house is fitted with high press

ure spray nozzles (i.e.,foggers) for c ooling in high temperatures, then th

ese can be used to increase RH duri ng brooding.

Chicks kept at appropriate humidity levels are less prone to dehydration

and generally make a better, more u niform start.

HUMIDITY As the chick grows, ideal RH falls.

High RH from 18 days onward can cause wet litter and its ass

ociated problems.As broilers increase in live weig

ht, RH levels can be controlled using ventilation and heating s

ystems.

HEAT STRESS Heat stress negatively affects g

rowth rate and livability. Effects of heat stress can be mi

nimized by altering the environment to reduce the temperatur

e experienced by the bird.

CONTROL OF HEAT STRESS Normal body temperature of a broiler chic

ken is106ºF (41).

Absolute temperature at which a broiler is under heat

stress is related to its age, temperature and.

As a rule of thumb, for fully feathered bird s, a “heat stress index” (RH plus tempera

ture in ºF) of 160 is considered heat stress .

CONTROL OF HEATSTRESS Broilers regulate their body temperatur

e by two methods: radiation/convection of heat and evapora

tive cooling throughrespiration. Within the temperature range 5 5 –7

7ºF (13–25ºC), heat loss is mainly acco mplished through physical radiation an

d convection to the cooler environment.

CONTROL OF HEATSTRESS As the temperature rises ab

ove86ºF(30ºC) t he maj or i t y of hea t loss is accomplished by ev

ddddddddd ddddddd ddd dddddd g, and increased respiration

ddddd

CONTROL OF HEATSTRESS Panting allows the bird to control body t

emperature by evaporation of water fro m the respiratory surfaces and air sacs.

The process uses energy. In conditions o f high humidity, panting is less effective.

Where high temperatures are maintained for long periods, or humidity is very hi

gh, panting may be insufficient to contro l body temperature and the bird may ex

perience heat stress .

CONTROL OF HEATSTRESS As the bird passes into acondition of heat stress, r

ectal temperature rises, h eart rate and metabolic r

ate increase and oxygena tion of the blood decrease
