In the Region of "Castilla y León" (Spain), as in other Mediterranean areas, fresh suckling lamb meat is regarded as having a high edible quality. The EU granted this product a Protected Geographical Indication (PGI) "Lechazo de Castilla y León" in 1999. In this study, several carcass characteristics of suckling lambs protected by this PGI were determined, while the effects of breed, sex, and carcass weight were studied. Some differences in carcass characteristics within the three PGI authorized breeds have been detected. Neither carcass weight nor conformation measurements were good predictors of the composition of the PGI protected suckling lamb carcasses. The best predictors were fatness and composition of the leg and loin tissues, although dissection of these joints is not feasible on a daily basis. Lastly, some differences, due to sex and weight were identified in conformation, fat percentage, jointing and joint composition. Differences were, however, rather small, due to the lambs' young age and low variation in carcass weight.
在西班牙的“卡斯蒂利亚-莱昂自治区”，与其他地中海地区一样，新鲜的哺乳羔羊被认为具有很高的食用品质。欧盟于1999年授予该产品“卡斯蒂利亚-莱昂哺乳羔羊”受保护地理标志（PGI）。在本研究中，测定了受该PGI保护的哺乳羔羊的几个胴体特征，同时研究了品种、性别和胴体重量的影响。已检测到三个获得PGI授权品种的胴体特征存在一些差异。胴体重量和外形测量都不是PGI保护的哺乳羔羊胴体组成的良好预测指标。最佳预测指标是腿部和腰部组织的脂肪含量和组成，不过每天对这些关节进行解剖是不可行的。最后，在外形、脂肪百分比、分切和关节组成方面，发现了一些因性别和体重导致的差异。然而，由于羔羊年龄小且胴体重量变化小，差异相当小。
