Early Feed Restriction, a Tool to Improve the Feed Efficiency in Broilers

A. Mahmud, F.M. Khattak, Z. Ali, T.N. Pasha and U. Farooq


A restricted feeding trial involving broiler chicks was conducted to investigate the effects of different levels of feed restriction. An experiment was carried out with straight run broiler chicks (Hubbard) in which commercial feed from 11 to 18 days of age was restricted to 100, 90, 80 and 70% in groups A, B, C, and D, respectively. Each treatment had 3 replicates, having 30 chicks each. The results indicated that feed restricted with 70 and 80% resulted in a significant (p<0.05) reduction in body weight at the age of 18 days. After return to adlib feeding the birds were fully recovered from their body weight depression. Comparable increase in all growth parameters (body weight, feed intake and FCR) were observed in birds fed on restricted diets in week 2 and 3. However in last week, the significant improvement (p<0.05) in weight gain was noted in group B (90% restriction ) but FCR was significantly improved in group D (50% restriction) when compared with control.
