Sažetak
The aim of this research was to evaluate the inflfluence of species, sex and slaughter weight (≤24 kg ; >24 kg) on the slaughter characteristics, carcass measurements, meat pH and meat colour of Dalmatian Pramenka lambs and Croatian Spotted Goat kids. 92 lambs and 90 kids of both sexes were used in this study. The animals were reared under an extensive production system on pasture, and were with their mothers until slaughter. Dalmatian Pramenka lambs had higher (P<0.001) carcass weight, dressing percentage, skin with lower legs weight and weight of all analyzed internal organs (except spleen) than Croatian Spotted Goat kids. Slaughter weight had a signifificant inflfluence (P<0.001) on carcass weight and the weight of skin with lower legs and all internal organs, except the spleen. Females had higher dressing percentage (P<0.01) and lower skin with lower legs weight (P<0.05) than males. Species significantly influenced all investigated carcass measurements, except thoracis depth, in that the lambs’ carcasses were more developed than those of the kids. The significant(P<0.001 ; P<0.01) influence of slaughter weight was evident in all carcass measurements in that animals with higher slaughter weight had more developed carcasses. Male animals had greater hind limb length (P<0.01) than female animals. Species (P<0.05) and slaughter weight (P<0.001) had a significant influence on the pH of m. longissimus dorsi. Dalmatian Pramenka lambs had lighter meat with greater (P<0.001) L* values of m. rectus abdominis (MRA) and m. semitendinosus (MS) than Croatian Spotted Goat kids. Redness (a*) of MRA was significantly (P<0.001 ; P<0.05) affected by species and slaughter weight, respectively. Males had greater (P<0.001) L* value of MRA than females, as well as b* value of MS (P<0.01).
