Effect of breed on carcass weight and conformation in lambs.
Data on 86 carcasses were analysed. For Aragonese, Spanish Merino, Manchega and Lacaune wethers of the "Ternasco" type, slaughtered at 65-90 days of age, cold carcass weight averaged 10.68, 10.76, 11.83 and 11.49 kg respectively, and for British (Welsh Mountain, Romney), New Zealand Romney, Argentine Corriedale and German Mutton Merino males slaughtered at 100-180 days of age, it averaged 10.80, 10.56, 10.09 and 10.93 kg. Some differences between breeds were significant. Data are tabulated on some carcass measurements and carcass quality scores for lambs of the different types.
