The objective of this study was evaluate the yields and weights of the organs, viscera, by-products and edible offal in 32 males castrate Morada Nova hair sheep breed, in feedlot, fed with diets containing 20.0 40.0 60.0 and 80.0 % of concentrate. The animals (8.11 ± 1.15 months old, 19.67 ± 2.97 kg BW) were slaughtered at 30.0 kg BW. A completely randomized blocks design, with four diets and eight replicates, was used. The crescent concentrate levels increased empty body weight (25.12, 25.69, 25.87, and 26.82 kg), liver (0.497, 0.565, 0.566, and 0.653 kg), gall bladder (0.009, 0.014, 0.020, and 0.033 kg), small intestine (0.460, 0.564, 0.582, and 0.650 kg), blood (1.258, 1.363, 1.295, and 1.597 kg), paws (0.607, 0.623, 0.620, and 0.692 kg), "buchada" offals (4.489, 4.602, 4.750, and 5.055 kg) and their yields in relation to slaughter body weight (14.51, 14.75, 15.50, and 16.29%), while there was linear decreasing for digestive tract content (5.80, 5.47, 4.80, and 4.16 kg) and omasum (0.089, 0.070, 0.063, and 0.058 kg). No treatment effect on weights and yields of some organs, viscera, by-products and internal fats was observed. Beyond the used concentrate levels, the yields and weights of non carcass components were high, with values that directly reflect in less yields and weights of carcass of the feedlot Morada Nova hair sheep.
