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.
Highlights
The basic task of production animal feeding is to achieve the highest possible production of quality meat with minimal feed consumption and the lowest possible production costs
Animal nutrition has gone through several stages in its development, starting from complete empiricism to the modern concept of nutrition, which is based on very precise research of metabolic and biochemical changes at the cellular level
The goal of fattening pigs and broilers is to increase the body weight of the animal to obtain a larger amount of meat and fat by using mostly plant nutrients, with a smaller amount of nutrients of animal origin
Summary
The basic task of production animal feeding is to achieve the highest possible production of quality meat with minimal feed consumption and the lowest possible production costs. With the development of scientific disciplines in the field of nutrition, as well as consumer awareness, the imperative in animal husbandry has become the quantity of food produced, and the quality of food produced. The role of fat in human and animal nutrition is primarily energetic. The raw materials for the synthesis of unsaturated fatty acids in the body are essential fatty acids that are ingested through feed. Essential fatty acids serve as the building units of many hormones, especially prostaglandins, leukotrienes, thromboxanes and others, but they are a very important component of cell membranes. Lack of essential fatty acids can lead to severe disorders. Up to 6% fat in the mixture accelerates the utilization of feed
