An experiment was conducted to examine the effect of compensatory growth on the performance and carcass characteristics of broiler chicks. The chicks were divided into three experimental groups (A, B and C). Group A of chicks was offered the control diet which was formulated to meet the nutrient requirement of the broiler chicks for 45 days. Group B was subjected to physical feed restriction in the term (8-21 days), these chicks were offered 35% of their nutrient requirement in this period then they were refed with the control diet to the end of the experiment. While group C was restricted by given a low protein and high fibre diet in the term (8-21 days), then they were refed with the control diet to the end of the experiment. Results revealed that there was no significant difference in feed intake, weight gain, carcass weight, liver weight, abdominal fat weight and gizzard weight. Also results revealed that there was significant difference (p<0.05) in feed conversion ratio and alimentary tract weight. Dressing percentage was 74.13%, 74.93% and 75.72% for group A, B and C respectively.
