Sažetak
The proximate composition and mineral content of light lambs muscle (derived from Istrian and Dalmatian Pramenka breeds) were studied. The musculus longissimus dorsi (MLD) muscle samples of 30 carcasses were analysed and the effects breed and sex were studied. Because no significant differences were found between sexes, data classified according to this factor were not included. A comparison of each variable (carcass weight (ranging 8.5 &#8211; 12.5 kg), moisture, protein, fat and mineral elements) between breeds was performed by Student&#8217; s t-test and correlation coefficients between variables and carcass weight were determined by PROC CORR procedure of SAS statistical package (1999). Although lambs of investigated breeds were of similar slaughter age (2.5 months), mean value for carcass weight was higher (P<0.05) in Dalmatian Pramenka lambs than in Istrian lambs (11.5 kg vs. 10.4 kg, respectively). Breed had a significant influence on moisture and fat contents, whilst mineral composition (with the exception of selenium) was scarcely affected by breed and sex. Fat and moisture contents were significantly correlated with cold carcass weight (r = 0.46 and -0.50, respectively). The magnesium, calcium, manganese and selenium contents were significantly (P<0.05) correlated (r = 0.50, -0.46, 0.44 and 0.54, respectively) with carcass weight. This study contributes to characterization of lamb carcasses from Istrian Sheep and Dalmatian Pramenka breeds and provides new data on the composition of the MLD of light lambs.
