ABOUT NON-TRADITIONAL FEED ADDITIVES INFLUENCE ON SAFETY OF THE YAKUT BREED HORSES LIVE WEIGHT

Abstract

Horse breeding is one of the rapidly developing branches of animal husbandry in Yakutia. Horses of the Yakut breed are only type of farm animals that are kept year-round in harsh conditions of the sharply continental climate of Yakutia. In winter, animals experience a significant lack of nutrients and minerals. This is due to fact that basic diet consists of natural feed winter pasture and hay. Therefore, the goal was to study the effect of complex feed additives from local natural raw materials on the change in live weight and biochemical composition of the blood of animals. This study used standard animal research methods. The use of non-traditional feed additives in feeding of horses contributed to an increase in the supply of nutrients and minerals to the rations. Improving feeding conditions affected the live weight of horses (live weight loss was 5.75 % и 5.45 %). The change caused by inclusion of non-traditional feed additives in the diets of horses had a positive effect on the morphological and biochemical composition of the blood animals. In horses from the experimental groups, an increase was found in the blood in total protein by 0.50 % and 0.30 %, albumin by 0.36 and 0.20 %, globulin by 0.13 and 0.10 %, hemoglobin by 2.91 and 1.33 %, calcium by 3.56 and 1.29%, phosphorus by 5.71 and 1.90 %. Thus, use of experimental non-traditional feed additives in feeding horses in winter contributes to the best preservation of live weight. This is due to the improvement of mineral and vitamin nutrition in a difficult period of deficiency of macro- and microelements, vitamins in the diets of horses. This improves metabolism, which is reflected in the morphological and biochemical composition of blood of horses.
