Effect of quantitative food restriction and photoperiod during the rearing period on the performance of two strains of broiler breeder hens


, : Effect of quantitative food restriction and photoperiod during the rearing period on the performance of two strains of broiler breeder hens. Revue de l' Agriculture 35(5): 3017-3028

During the rearing period, Hubbard and Hybro were subjected to feed restriction (by <less or =>15%) and daily photoperiods of 8 or 12 h. Hybro birds reached sexual maturity (50% laying rate) significantly earlier than Hubbards (184 vs. 197 days). On the 12-h light regime, maturity was reached on average at 192 days vs. 189 on an 8-h regime. Both strains had a typical production period of 40 wk during which there was no significant breed difference in laying performance.
