Abstract: Changes in the lipid and protein oxidative stability during refrigerated storage are studied in m. Semimembranosus и m. Supraspinatus in male lambs fed sunflower meal, rapeseed meal and dried distillers’ grain with solubles (DDGS). The diet composition influenced significantly the amount of lipid oxidation products on the 24 h (Р<0.01) and 6-th day (Р<0.05) as well as the carbonyl compounds on the 6-th day of storage (Р<0.05). The type of the muscle affected significantly the oxidative changes of the lipids and proteins as in both components the differences in the accumulated substances are significant on the 48th h of the storage (Р<0.01; 0.001). The dynamics of the lipid oxidation in both muscles shows differences (Р<0.05) in the amount of the oxidation products in the group fed sunflower meal between 24th h and 6th day of storage. In the three groups increase in the contents of the carbonyls between 24h and 6th day in m. Semimembranosus (P<0.05) as well as between 48th h and 6th day (P<0.05) in m. Supraspinatus were found.
