This study was conducted to evaluate the effect of feed restriction time and age, on production performance of broiler chickens. A total of 420 day-old male broiler chickens (Cobb-500) were randomly assigned to 7 treatments each in 4 replicates of 15 birds per pen. Broilers were fed ad libitum through out the experiment as the control (T0) and other six groups were fed restricted as: T1 (8 h/day in 7-14 days of age), T2 (16 h/day in 7-14 days of age), T3 (8 h/day in 14-21 days of age), T4 (16 h/day in 14-21 days of age), T5 (8 h/day in 21-28 days of age), T6 (16 h/day in 21- 28 days of age). Results from this experiment indicated that feed intake, feed conversion ratio and body weight gain of broilers during 1-42 days as well as final body weight at 42 days were not significantly affected by feed restriction. In an overall conclusion it can be said that feed restriction resulted in compensatory growth and in turn lead to improvement of farm economy.
