Resumo: Carcasses of Churro Galego Bragançano purebred and Suffolk and Merino Precoce crossbred lambs reared under three different conventional production system of northeast of Portugal were evaluated. Carcasses of male lambs had larger muscle longissimus width (P < 0.05) and smaller subcutaneous fat thickness (P < 0.05) than the female lambs. Carcasses of crossbred lambs had higher (P < 0.05) compactness indices and leg and shoulder proportion than Bragançano purebred. Suffolk crossed had lower KKCF proportion (P < 0.05) than Bragançano and Merino crossbred lambs. Male lambs had higher (P < 0.05) muscle proportion in almost all carcass joints than the female lambs. It was concluded that Suffolk can be used as sire breed in Bragançano ewes to produce lambs with leaner and more compact carcasses and better fat distribution, which allows slaughtering at higher slaughter weight, specially in more intensive production systems. Female lambs should be slaughtered at lower carcass weight than male lambs in order to produce carcasses with the same fattening degree.
