Avaliaram-se as características da carcaça, a composição tecidual da secção entre a 9ª e a 11ª costela, a composição centesimal do músculo longissimus dorsi e a proporção dos componentes não-carcaça de cordeiros terminados em confinamento com dietas contendo 1,49; 1,55; 1,62; ou 1,68 Mcal de energia líquida/kg de matéria seca. As dietas foram compostas de silagem de milho como volumoso e concentrado composto de um produto comercial e do suplemento energético Lacto Plus®. Foram utilizados 16 cordeiros machos não-castrados desmamados aos 74 ± 18 dias de idade e abatidos aos 84 dias de confinamento. O delineamento experimental foi o inteiramente casualizado, com quatro níveis de energia, cada um com quatro repetições. A porcentagem de perna diminuiu linearmente, enquanto a porcentagem de costilhar aumentou, também de forma linear, com o aumento do nível de energia na dieta dos cordeiros. A proporção de músculo diminuiu e a de gordura aumentou de acordo com o nível de energia na dieta. A composição centesimal do longissimus dorsi não foi influenciada pelo nível de energia da dieta. As porcentagens de sangue e gordura interna e renal aumentaram linearmente, enquanto as de vísceras cheias e de conteúdo gastrintestinal diminuíram linearmente com o aumento do nível energético das dietas. O aumento do nível de energia líquida na dieta de cordeiros em confinamento reduz a proporção de perna e aumenta a de costilhar, além de aumentar a proporção de gordura e diminuir a de músculo na secção entre a 9ª e a 11ª costela. The objective of this study was to evaluate the characteristics of the carcass, tissue composition in the section between 9th and 11th ribs, centesimal composition of Longissimus dorsi muscle and the proportion of the non-carcass components of non-castrated male lambs, fed in feedlot with diets containing 1.49, 1.55, 1.62 and 1.68 Mcal of net energy/kg of dry matter. Diets were composed by corn silage as the roughage and the concentrate was composed by a commercial ration and the energetic supplement Lacto Plus®. It was used sixteen non-castrated male lambs, weaned at 74 ± 18 days of age and slaughtered when they completed 84 days of feedlot. A completely ramdomized design was used, with four levels of energy, each one with four replicates. The percentage of leg linearly decreased while the percentage of rib linearly increased as the level of energy in the diet of the lambs improved. There was a linear decrease in the proportion of muscle and linear increase in the proportion of fat according to the level of energy in the diet. The centesimal composition of Longissimus dorsi muscle was not influenced by the level of energy of the diet. The percentages of blood and internal and kidney fat increased linearly while the percentages of full viscera and gastrointestinal content decreased linearly with the increase in energy level in the diets. Increasing levels of net energy in the diet of lambs in feedlot promotes reduction in the proportion of leg and increase the proportion of rib. Additionaly, it promotes an increase in proportion of fat and it reduces the proportion of muscle in the section between the 9th and 11th ribs
