Twenty-two sheep with average age of 18 months were used. Linear regressions were determined between the studied characteristics. The mean body mass, body condition score (BCS), and BMI were 49.09±7.8 kg, 2.69±0.81, and 10.66±0.99, respectively. The BMI was correlated with the BCS (r = 0.51) and internal fat (r = 0.81). Multiple linear equations, involving BMI and BCS, yielded correlation coefficients between 0.50 and 0.76, with significant values for all studied characteristics. The body mass index allows estimating the body energy reserves of Corriedale sheep. Resumo - O objetivo deste trabalho foi identificar relações do índice de massa corporal (IMC) com as reservas energéticas corporais e a composição tecidual de cortes da paleta e do pernil de cordeiros Corriedale. Vinte e dois cordeiros com idade média de 18 meses foram utilizados. Regressões lineares foram determinadas entre as características estudadas. A massa corporal média, o escore de condição corporal (ECC) e o IMC foram 49,09±7,8 kg, 2,69±0,81 e 10,66±0,99, respectivamente. O IMC correlacionou-se ao ECC (r = 0,51) e à gordura interna total (r = 0,81). Equações lineares múltiplas que envolveram o IMC e o ECC forneceram coeficientes de correlação entre 0,50 e 0,76, com valores significativos para todas as características estudadas. O índice de massa corporal permite estimar as reservas de energia corporal de ovinos Corriedale.  aBody fat  aBody mass index  aBody measurements  aLamb meat  aSheep  aCordeiro  aCorriedale  aOvino  aOvis Aries1 aMENDONÇA, G. de1 aBRUM, L.
