Abstract

Broiler breeders are characterized by their fast growth and sensitivity to light stimuli. Unlike commercial layers, they have a lower egg production rate and are kept on the floor during rearing and laying periods. Fertile eggs are the primary objective, necessitating careful management of their egg-laying properties, while controlling their body weights. Unrestricted feeding leads to early laying with poor peak and persistency in egg production. Therefore, nutrient intake must be restricted to achieve target body weights at light stimulation (22 weeks). This involves both quantitative and qualitative feed restrictions. Quantitative feed restriction can lead to issues such as poor feed distribution, uniformity, abnormal behaviour, feather pecking and cannibalism. These challenges are often mitigated by skip-a-day feeding and qualitative feed restriction. Uniformity in body weight, frame size, and sexual maturity at the point of lay is crucial for achieving peak production. Feeding strategies must aim to treat the flock as a single entity despite individual variations.
