Influence of CLA addition in non-ruminant diets on lipid index values

Abstract

In monogastric animals, tissue fatty acid profile directly reflects the fatty acid profile present in the animal's diet. Inadequate ratio of fatty acids in food can lead to negative effects on human health. Conjugated linoleic acid (CLA) is a group of isomers of linoleic acid (C18:2), and its most interesting role is in the prevention of tumors, atherosclerosis and diabetes. CLA is found in ruminant meat and milk, and since pigs and poultry do not have the ability to synthesize CLA, it is possible to add them to animal feed with biotechnological solutions. The scientific public imposes modern parameters for determining the nutritional value of fatty acids, in which the AI – index of atherogenicity, TI – index of thrombogenicity and H/H - hypocholesterolemic/hypercholesterolemic ratio are distinguished. The aim of this study was to determine the effect CLA addition to the diet of non-ruminants on the lipid indices of certain categories of meat, from the aspect of consumer health needs. A significant influence of the correction of feed's fatty acid composition on the lipid indices in food of animal origin was determined.
