Summary
1. The effect of prolonging the non‐productive period by offering cracked grain after food withdrawal on the performance of moulted broiler breeders was investigated. 2. Each increase in the non‐productive period resulted in a gradual decrease in egg production but a gradual increase in the percentages of hatching eggs, fertility and hatchability. 3. There were no significant differences between hens fed on cracked grain for 2 or 3 weeks for any of the performance characteristics, except fertility and hatchability. The best fertility and hatchability were observed in hens fed on cracked grain for 3 weeks.
