Abstract ‒ The objective of this work was to compare the zootechnical
performance of Dorper x Santa Inês crossbred lambs finished in grazing
systems on Megathyrsus maximus Aruana cultivar pasture, with and without
shading, and in a feedlot. Twenty-four non-castrated lambs were used in
a completely randomized experimental design, with the three following
treatments with eight replicates each: 'Aruana' pasture without shading +
supplement; 'Aruana' pasture with shading + supplement; and feedlot, with
diet containing ryegrass hay and concentrate at a 20:80 ratio. The treatments
did not influence lamb age at slaughter, birth weight, leg compactness, true
yield, and main cut yield, except that of breast tip + flank that was lower for the
pasture with shading. However, average daily gain, body condition score, live
weight at slaughter, carcass compactness index, cold carcass and empty body
weights, and cold carcass yield differed between treatments, showing higher
values in the feedlot. Termination in the feedlot increases the zootechnical
performance of Dorper x Santa Inês sheep and favors a lower age at slaughter,
as well as a greater weight of the main commercial cuts, but not their yield.

Resumo ‒ O objetivo deste trabalho foi comparar o desempenho zootécnico de
cordeiros mestiços Dorper x Santa Inês terminados em sistemas de pastejo sobre
pastagem de Megathyrsus maximus cultivar Aruana, com e sem sombreamento,
e em confinamento. Utilizaram-se 24 cordeiros não castrados em delineamento
experimental inteiramente casualizado, com os três seguintes tratamentos, com
oito repetições cada um: pastagem de 'Aruana' sem sombreamento + suplemento;
pastagem de 'Aruana' com sombreamento + suplemento; e confinamento,
com dieta contendo feno de azevém e concentrado na proporção de 20:80. Os
tratamentos não influenciaram a idade dos cordeiros até ao abate, o peso ao
nascer, a compacidade da perna, o rendimento verdadeiro e o rendimento dos
cortes principais, exceto o da ponta do peito + flanco que foi menor na pastagem
com sombreamento. Entretanto, o ganho médio diário, o escore de condição
corporal, o peso vivo ao abate, o índice de compacidade da carcaça, os pesos
da carcaça fria e do corpo vazio, e o rendimento de carcaça fria diferiram entre
os tratamentos, com valores superiores no confinamento. A terminação em
confinamento aumenta o desempenho zootécnico de ovinos Dorper x Santa
Inês e favorece a menor idade ao abate, bem como o maior peso dos principais
cortes comerciais, mas não o seu rendimento.
