Sažetak
Carnosine is a dipeptide with antioxidative effects in broiler muscles. Its anti-ageing effect was also determined recently, which is especially important for human health and vitality preservation. The research investigated concentration of carnosine in breast and tigh muscles of Cobb 500 broilers. It was carried out on 20 male and female broilers that were conventionally fattened for 42 days. Carnosine concentrations and TBARS values were measured on fresh breast and tigh muscles with respect to broiler sex. Content of carnosine was slightly higer in female broiler breast muscles than in male´s (1079.85 : 1012.66 μg/g tissue ; P> 0.05). Female broiler tigh musle tissue also contained higher carnosine values than male´s (464.69 : 404.97 μg/g tissue ; P> 0.05). The research proved that carnosine was more deposited in breast muscle tissue than in thigh muscle tissue, irragardless of broiler sex. Lipid peroxidation products measured as TBARS values (mg MDA/ kg tissue) did not statistically differ according to broiler sex or muscle type (P>0.05). Further research needs to be directed towards control of peroxidation products during meat storage.
