      Effects of metabolizable energy (ME) levels were evaluated on nutrient digestibility and carcass characteristics in Morada Nova lambs. Forty Morada Nova lambs with initial weight of 12.2 ± 2.05 kg, were used. Five treatments were defined according to metabolizable energy (0.96; 1.28; 1.72; 2.18 and 2.62 Mcal/kg DM) levels. It was used a randomized block design. Animals were slaughtered when body weight mean (BW) of the group reached 25 kg. Linear effect was observed for digestibility coefficient of DM, OM, EE, CP, NDF, TC, FC and NFC. Daily weight gain (DWG) presented linear increase (P Foram avaliados os efeitos de diferentes níveis de energia metabolizável (EM) sobre a digestibilidade e características de carcaça em cordeiros Morada Nova. Utilizaram-se 40 cordeiros Morada Nova, com peso inicial de 12,2 ± 2,05 kg. Cinco tratamentos foram definidos de acordo com os níveis de energia metabolizável (0,96; 1,28; 1,72; 2,18 e 2,62 Mcal/kg MS), conduzidos em delineamento de blocos ao acaso. Os animais foram abatidos quando a média de peso corporal (PC) do grupo atingiu 25 kg. Foi observado efeito linear para o coeficiente de digestibilidade da MS, MO, EE, PB, FDN, CT, FC e NFC. O ganho de peso diário (GPD) apresentou aumento linear (P
