BodyWeigh

t

Period o continued growth and

development.

90% o skeletal growth is completed

by around 80-95 days o age.

Accelerating growth & weight gain

to prepare birds or sexual maturity

and mating-up.

Rapid growth o oviduct, ovaries and

testes.

Sexual maturity occurs 10-14 days

ater lighting-up.

Rapid growth o skeleton, immune,

digestive & cardiovascular systems

& eathers.

Achieve target body weight uniormly.

Develop chick appetite through good

brooding practice.

Ensure adequate eeder and drinker

space.

Monitor crop ll.

Monitor bird behavior.

Maintain optimum temperature,

humidity and ventilation.

Initiate weekly body-weight monitoring.Start to record individual body weightsrom 14-21 days o age to calculateCV%.

Where light-proong is available reducelight intensity to 10-20 lux (1-2 ootcandles) by 10 days o age.

Achieve target body weight uniormly.

Grade at 28 days.

Grade in to 2 (CV% below 12) or 3

populations (CV% above 12).

Within each graded population control

growth and eed to achieve revisedbody-weight targets by 63 days.

Stop movement o birds between

graded populations at 63 days.

At 63 days review body weights

against target; re-draw target i

necessary.

Feed emales to stimulate and supportincreases in egg production, egg weightand growth.

Introduce the breeder ration no laterthan 5% production.

Feed males to achieve growth and

support ertility. Follow a male reduction program and

assess male physical condition or:

Legs and eet Fleshing Facial color Vent condition

Where light proong is available do notexceed 13 to 14 hours o light a day (30-60 lux/3-6 oot candles).

Increase eed levels to stimulate growthrate in line with targets and preparebirds or sexual maturity.

Assess pin bone spacing weekly tomonitor maturity.

Assess fock uniormity one week

beore rst light increase is planned: I birds are on target and even (CV%

below 10) light-up as recommended.

I birds are under target or uneven(CV% above 10), delay lighting by atleast 7 days.

Mate-up at 147 days; ensure males andemales are uniormly mature.

Observe eeding behavior regularly tomonitor separate sex eeding and eeddistribution.

Adjust eed allocation to achieve target

body weights uniormly:

Birds under target weight should

ollow a prole which brings them

back to target by 105 days.

Birds over target weight should

ollow a prole which runs parallel to

the target curve.

Birds should not lose body weight

during this time.
