Aim of study was to investigate the relationship of EUROP carcass fatness and conformation classes with carcass and meat quality characteristics in thin-tailed (Kivircik) and a fat-tailed (Kangal Akkaraman) lambs. A total of 96 lamb carcasses (48 Kivircik and 48 Kangal Akkaraman breed) were examined. Distribution of carcasses in conformation and fatness classes were more limited in Kangal Akkaraman carcasses. More accurate predictions were obtained in Kivircik lambs compared to Kangal Akkaraman lambs in terms of backfat thickness, kidney knob and channel fat percentage, longissimus thoracis muscle area, weights of high-value carcass joints, weights of tissues in the hind limb and muscle/bone ratio. EUROP classification system was not appropriate for predicting meat quality in thin-tailed and fat-tailed lambs. The combination of EUROP fatness and conformation classes with cold carcass weight can be used to predict weights of high-value carcass joints and weights of hind limb tissues.
本研究旨在探讨欧洲育肥分级体系（EUROP）中体脂和体型等级与小尾寒羊（Kivircik）和大尾寒羊（Kangal Akkaraman）羔羊胴体和肉质特性的关系。共检测了 96 个羔羊胴体（48 个小尾寒羊和 48 个大尾寒羊）。在大尾寒羊胴体中，体型和体脂等级的分布更为局限。与大尾寒羊羔羊相比，小尾寒羊羔羊在背膘厚、肾脂和肌间脂肪百分比、胸腰椎肌肉面积、高价胴体关节重量、后躯组织重量和肌肉/骨比方面的预测更为准确。EUROP 分类系统不适用于预测小尾寒羊和大尾寒羊的肉质。将 EUROP 体脂和体型等级与冷胴体重相结合，可以预测高价胴体关节重量和后躯组织重量。
