Evaluation of the functionality of EUROP carcass classification system in thin-tailed and fat-tailed lambs

Abstract

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.
