Conteúdo:  This study investigated the effects of flock, sex and leg shape scores (assessed in the live animal) on the carcass yield, conformation and composition of purebred Texellambs. Two flocks were managed in a common environment. The first (Lean Index flock) had a 6-year history of selection for lean tissue growth rate using an index of live weight and ultrasonic muscle and fat depths measured at 20 weeks of age. The second (Conformation flock) had recently been established by mating rams of extreme conformation selected from the UK Texel population with ewes in the Lean Index flock. Lambs were evaluated at a mean age of 139 days at the end of an 11-week performance test in which they were reared indoors on a concentrate diet. Prior to slaughter, the lambs were assessed for conformation of the hind leg (leg shape score). Mean live weights and ultrasonic fat depths dia not differ significantly between flocks or leg shape scores but ultrasonic muscle depths were highest in the high leg shape score (27.9, 27.7 and 30.1 mm in low, medium and high scores, s.e.d. 0.55). At constant slaughter weight, the lean weight in the side was 04 kg higher in the Conformation flock and 0.3 kg higher in lambs of high v. low leg shape score (P < 0.001) with no significant differences in other tissue weights. Consequently, lean : bone ratio and lean proportions in both the live weight and carcass were higher in the Conformation flock and in lambs of high leg shape score. Lambs of high leg shape score ... Mostrar Tudo
