EFFECT OF RESTRICTED FEEDING ON THE PERFORMANCE OF BROILERS

摘要

An experiment was conducted on the performance of commercial broiler chicken under different hourly feed restriction. Ninety six 21 days old broiler chickens (uniform weight) were randomly divided into four experimental groups, comprising of three replicates. Each replicate was consisted of 8 birds. The birds were kept under four different hourly feed restriction treatments, viz. Control group (C) having ad libitum feeding for 24 hrs, T, having 4hrs feed restriction, T2 having 6hrs feed restriction and T3having 8hrs feed restriction in a day. Common basal diets and same feeding space/bird and watering space/bird had been provided for each group. Best performance in terms of final body weight was observed in Control group followed by T2 T( and T3 respectively, whereas the weekly gain in body weight during last week i.e. 6th week was highest in T3 followed by T2 T, and C respectively and better feed efficiency was found in T2 followed by C, T3 and T, group. Therefore, it can be concluded that the T2group i.e. having 6 hrs feed restriction showed better performance in terms of body weight gain and feed efficiency.
