Achieving persistene production of breeder flocks

摘要

Giving sufficient attention to broiler breeders early on can ensure good performance through the life of the birds.Persistency through lay is a key target in managing broiler breeder flocks for maximum output of hatching eggs. A good flock will maintain a high level of production after peak, and to achieve this requires starting the birds on the correct course from very early on. The essential factor is flock uniformity. Feeding a group of chickens to meet the needs of the average bird inevitably undernourishes heavier birds and overfeeds lighter ones. The more uniform a flock, the more it can be fed to meet the needs of a greater proportion of birds and, feed can be reduced without accelerating the normal decline in production.
