One hundred twenty broilers from each of the three commercial stocks A, B and IBL-80 were reared to the age of 7 weeks and compared for abdominal fat, abdominal wall thickness, total carcass fat and other carcass traits. The average body weights of stocks A, B and IBL-80 at 5-weeks were 1440, 1295 and 1192 g, respectively. The corresponding values at 7-weeks were 2345, 2199 and 2139g.Percent abdominal fat was more in the females. Abdominal fat expressed as percent to live weight was highest in Stock B (1.80) followed by IBL-80 (1.46) and stock A broilers (1.26). Abdominal wall was relatively thicker in males. The thickness of abdominal wall was highest 13.7 mm in stock A followed by 13.1 mm in stock B and 12.4 mm in IBL- 80 broilers. The percent carcass fat was highest in IBL-80 (9.0) followed by stock B (8.6) and stock A (6.9). The phenotypic correlations between percent abdominal fat and percent ether extract were significantly high with values ranging between 0.71-0.85 in all the three commercial stocks.
