Abstract
One hundred and twenty, forty-three-week-old laying hens were used in a study conducted to investigate the effects of feed restriction on the performance of laying hens. They were randomly allotted to four treatments comprising T1 (control or full feeding) and three feed restriction levels, T2, T3 and T4 which were 85, 75 and 65% of full feeding respectively. Each treatment was further divided into three replicates of ten birds each. Average feed intake, feed efficiency and egg production showed significant (pSO.05) differences between treatments. Body weight gain, egg weight, shell thickness and selected quality characteristics (Albumen and yolk indices and Haugh units) showed no significant (P>O.05) differences between treatments. Groups on l and T2 did not differ significantly (p>O.05) with regard to egg production, feed efficiency and egg quality characteristics. Economically, it is viable to restrict the feeding of laying hens since this will reduce the cost of production. However, the level of restriction should be moderated by the performance of the birds. It is concluded that laying hens can be restricted to 85% of full feeding without adverse effects on performance.
