[Effects of leanness and emaciation on qualitative characteristics of the fatty tissue of cattle]

The purpose of the studies was to determine the basic composition, the total content of saturated, unsaturated and polyunsaturated fatty acids of perirenal fat of cattle according to the degree of fatness. The studies were carried out on 60 cows of the lowland black-and-white breed at about 4 years of age, which were divided into 4 groups according to the degree of fatness: well-fed, lean, moderately and completely emaciated. It was found that with decrease of the fatness degree only the basic composition of perirenal fat changed significantly; the chemical composition of triglycerides remains virtually unchanged.
