One hundred twenty birds from each of the three commercial stocks A, B and IBL-80 were reared to the age of 7 weeks and compared for dressing yield, cut-up parts and meat: bone ratio. Stock differences were found to be significant for body weights at 5 and 7 weeks of age. The average values for 5-week body weight were 1440, 1295 and 1192g for the stocks A, B and IBL-80. Corresponding values for 7-week body weight were 2345, 2199 and 2131g. IBL-80 birds produced higher percent dressing yield (68.27) followed by stock A (67.36) and stock B (65.56) at 7 weeks of age. The percent yield of various cut-up parts were in sequence of breast> back> thigh> drumsticks> wings> neck in all the stocks. Percent breast yield was found to be greater in stock B at 5 weeks and in stock A at 7 weeks of age. At 5 weeks, percent thigh yield was maximum in stock B followed by stock A and IBL-80 where as at 7 weeks, stock B was followed by stock A and IBL-80. Drumsticks had highest percent yield in stock A followed by IBL-80 and stock B both at 5 and 7 weeks of age. Meat: bone ratio for the whole carcass was found to be highest in stock A at 5 weeks and in stock B at 7 weeks of age. Among the cut-up regions, breast had the highest meat: bone ratio (5.09 to 7.03) in all stocks and at both the ages.
