Abstract

The objective was to evaluate the composition of carcass cuts and tissue of lambs shoulder and leg finished in feedlot receiving diets containing whole or disabled soybean grain with two concentrate levels (50% and 80% of DM). There were used 20 crossbreed entire male lambs, 120 days of age and initial body weight of 22.6 ± 2.06 kg. A completely randomized design was used, allocated in a factorial arrangement 2x2 (levels concentrate and processing of soybean grain). The slaughter criterion was body condition between 3 and 3.5. The weight of sirloin cut was superior with 80% of concentrate. In the shoulder tissue composition, the level of 50% concentrate increased the ratio of subcutaneous fat. In natura soybean provided higher values for weight and ratio of subcutaneous and total fat. For the leg tissue composition, the grain of disabled soybean showed higher muscle yield and muscle:bone ratio. Diets with 80% of concentrate, regardless of processing soybean grain, improved commercial yield and the diets containing disabled soybean more edible portion.
