Substantiation of the influence of high-quality feed resources on realization of the genetic potential of farm animals

Purpose. Substantiation of expediency of taking into account indicators of quality, safety of feed and feed raw materials during animal feeding, development of structure of rations and compound feed products. Methods. During determination of the quality and safety indicators, measurement methods, developed, improved and adapted at the Institute of Feed Research and Agriculture of Podillya of NAAS and methodological approaches used in international practice and established by current regulations and standards, were used. Results. Taking into account the detailed chemical composition of feed ensures efficient use of feed, balanced diets, obtaining biologically complete livestock products. For proper protein nutrition of animals not only the crude protein content, but also the protein content, composition and ratio of amino acids in it, the content of soluble and fissile protein, the amount of total, protein and non-protein nitrogen, neutral-detergent and acid-detergent insoluble should be taken into account. In order to ensure adequate carbohydrate nutrition of animals, it is necessary to take into account the content of: nitrogen-free extractives; non-structural carbohydrates (starch, sugar, pectin, glycogen); crude fiber; neutral-detergent fiber; acid-detergent fiber; structural carbohydrates (hemicellulose, cellulose, lignin). The balance of lipid nutrition is associated with the content of crude fat, unsaturated fatty acids (linoleic, linolenic, arachidonic, etc.), acid and peroxide levels of fat. Conclusions. Determining the detailed chemical composition of feed will provide the animal with the necessary nutrients, rational use of available feed resources, realize the genetic potential of productivity and maintain animal health.
