Effects of slaughter weight and sex on carcass characteristics and lamb meat quality of Manchega Spanish breed were analysed. Forty-five lambs were divided into two slaughter weight groups: light (LW=21.7±0.16 kg; n=24) and medium (MW=27.8±0.16 kg; n=21). Dressing proportion and conformation were significantly different between groups and sex. There were also differences between light and medium group in fatness but not between males and females. Water holding capacity decreased with increasing slaughter weight (p<0.05) and was lower in females than in males (p<0.001). The increase in weight was associated with a decrease in L* (p<0.01), while a* showed an increase which failed to reach statistical significance. Slaughter weight and sex affected neither pH and its decrease post-slaughter nor meat toughness. ©
本研究分析了屠宰体重和性别对曼彻格西班牙羊品种胴体特征和羊肉品质的影响。将 45 只羔羊分为两组：轻体组（LW=21.7±0.16kg；n=24）和中体组（MW=27.8±0.16kg；n=21）。两组间及不同性别间的屠宰率和体型有显著差异。脂肪度在轻体组和中体组之间存在差异，但在雄性和雌性之间没有差异。持水力随屠宰体重的增加而降低（p<0.05），雌性低于雄性（p<0.001）。体重增加与 L值降低有关（p<0.01），而 a值增加，但未达到统计学意义。屠宰体重和性别均不影响宰后 pH 值及其下降，也不影响肉的嫩度。
