Effect of Feeding Time Restriction During the Growing Period on Growth Performance of Broiler Chickens

Abdul Azis and Afriani    

Abstract: Background and Objective: Feeding time restriction is an alternate, lower intensity type of feed restriction and is less stressful than other types. It is important to achieve beneficial effects from feed restriction without adverse effects on growth. This study aimed to determine the impact of feeding time restriction on growth performance of broiler chickens. Materials and Methods: Three hundred seven days old unsexed broiler chickens of the Lohmann commercial strain were used in a completely randomized design with 4 treatments and 5 replications. The treatments were the following: Broilers being fed ad libitum as a control group (P-0) and broilers having free access to feed during 9 h/day (P-1), 12 h/day (P-2) and 15 h/day (P-3). The feeding time restriction was done from 21-35 days of age. All data was analyzed based on a completely randomized design using SAS software. Results: Broilers had lower body weight gain, body weight and feed consumption due to feeding time restrictions P-1 and P-2, however, broilers that had access to feed during 15 h/day had a similar performance to broilers fed ad libitum. Feed conversion rates of broilers fed during 9 h/day were better than other treatments during the 1st week of feed restriction (21-28 days), however, there were no significant differences among the treatments during 29-35 days of age and the overall period of feed restriction (21-35 days of age). Conclusion: Broiler chickens with a feeding time restriction of free access to feed during 15 h/day during the grower period, had a similar performance at market age as broiler chickens with ad libitum feeding.
