Abstract: Objetivou-se avaliar as características quantitativas in vivo, da carcaça e dos cortes comerciais de cordeiros alimentados com dietas contendo 0; 12,5 e 25,0% de feno de amoreira em substituição ao concentrado. Foram utilizados vinte e quatro cordeiros Ile de France, com aproximadamente 60 dias de idade e 15 kg de peso corporal, confinados em baias individuais e abatidos aos 32 kg. Houve efeito linear crescente (R2 = 0,84) para a profundidade do tórax, índice de musculosidade da perna (R2=0,71) e para a relação músculo:osso (R2=0,95); decrescente (R2 =0,75) para o índice de compacidade da carcaça, peso da paleta (R2 = 0,78) e peso (R2=0,99) e comprimento (R2=0,86) do fêmur à medida que se aumentou o feno de amoreira na dieta; e comportamento quadrático para perdas por resfriamento (R2=1,0) e porcentagem de gordura intermuscular. O feno de amoreira pode ser utilizado na alimentação de cordeiros confinados sem prejudicar as características quantitativas da carcaça.

English Abstract: The aim of this study was to evaluate the in vivo quantitative traits of carcass and commercial cuts of lambs fed diets containing 0, 12.5, and 25.0% mulberry hay replacing the concentrate. Twenty-four Ile de France lambs at approximately 60 days of age, with 15 kg body weight, were confined in individual stalls and slaughtered at 32 kg. Increasing levels of mulberry hay in the diet resulted in a linear increase in chest depth (R2=0.84), leg muscularity index (R2=0.71), and muscle:bone ratio (R2=0.95); a linear decrease in leg compactness index (R2 =0.75), shoulder weight (R2=0.78), and femur weight (R2=0.99) and length (R2=0.86); and a quadratic response from chilling losses (R2=1.0) and percentage of intermuscular fat. Mulberry hay can be used in the feeding of feedlot lambs without compromising their carcass quantitative characteristics.
