With continuously improving genetics, the current broiler is robust with low mortality, excellent feed efficiency and high yield. This also applies to the broiler breeder, which the customer would like to see producing more and viable chicks. Therefore, adequate management of broiler breeders during the rearing is essential to achieve optimum production.
Focus on uniformity, body conformation, bodyweight profiles and feed management to create the ideal preparation of the pullet.
GOOD UNIFORMITY
The goal for the end of rearing is to have a sexually uniform flock with the correct body conformation for age. With high sexual uniformity, birds increase production faster into lay. Feed and weight gain can also be better managed and there will be lower mortality in early lay.
Flocks that peak high (88-91%) are flocks that increase production fast in the first three weeks.
From the second to third week the production should at least double. For example, 30% in the second week should become 60% in the third week.
The first days for the chicks will influence how the uniformity will develop. Provide 50g feed/pullet before placement, and a floor temperature of at least 28o C. 24 hours after placement, 95% of the crops should feel soft and pliable, indicating that the chicks have successfully located feed and water.
