摘要: Characteristics and yields of carcass cuts in Santa Ines sheep fed with different concentrations metabolizable energy. This study evaluated the weight gain (ADG), feed conversion (FC), efficiency (FE), characteristics retail levels energy (2.08, 2.28, 2.47 2.69 Mcal kg -1 DM). Twenty lambs, age mean body 50 days 13 0.56 kg, respectively, were distributed randomized block design five replications. We verified a linear increase effect (p 0.05) by rations. Nevertheless, weights hot cold theempty , expressed presented quadratic < 0.05), as we experimental diets. The influenced yield rib shoulder, loin eye area 0.05). In conclusion, manipulation level ration changes ADG, weight, shoulder yield, sheep.
