FATTY ACID COMPOSITION OF THE LIPID FRACTION OF COMPOUND FEED FOR FATTENING PIGS
Abstract
Fats are an important part of the diet of animals, so it is necessary to establish the fatty acid composition of compound feed for fattening, since at this stage of animal growth the quality and safety of pork is determined, which directly affects the quality of food. The paper contains the materials on the study of the fatty acid composition of the lipid fractions of compound feeds SK-26 and SK-31, which include 12 saturated, 5 monounsaturated and 6 polyunsaturated fatty acids. The proportion of each acid in the total structure of fatty acids as well as in the structure of its class was established. The ratio between the groups of omega-6 and omega-3 polyunsaturated fatty acids varied from 4.96 to 11.60 (the lipid fraction of SK-26 compound feed) and from 6.69 to 9.23 (the lipid fraction of SK-31 compound feed). The results obtained will allow further improvement of lipid nutrition of pigs and control of trophic chain when carrying out hygienic studies in industrial pig breeding.
