Flock uniformity
As the breeding companies continue to select primarily for broiler traits, it becomes more challenging to achieve high levels of parent stock performance. Generally, the hen performance traits are opposed to the broiler traits - and when one trait is enhanced through selection, another trait may suffer.
Recognizing that broiler performance and efficiency are always the driving factor in selection programs, the breeding company and production managers must do everything possible to obtain the best performance from parent flocks.
Many techniques of feeding, lighting and weight control have been refined in recent years. But of all factors affecting breeder hen performance, flock uniformity is the most important. Management must be geared to preserving flock uniformity while accomplishing the feeding and body weight control necessary for good reproductive performance. Birds that are uniform can be fed properly and light stimulated with the greatest effect, resulting in optimum production and persistency. Uniformity begins at day one, and continues throughout the life of the flock.
