Goats are important livestock species for meat and milk production. Meeting goat nutritional requirements is essential in maintaining goat health and the quality of derived food products. Dietary supplementation with certain bioactive compounds can improve the quality of diet and help to create a productive and economical nutrition program. The aim of this study was to evaluate the effect of several feed additives on the milk productivity of Saanen goats. According to the method of pairs of analogues, 72 dairy goats were distributed into four groups (18 goats/group): the control (CG) – the conventional diet with no additives: the experimental groups 1 (EG1) - the diet with 10% extract of balsamic poplar buds; the experimental groups 2 (EG2) – the diet with vegetable protein hydrolysate; the experimental groups 3 (EG3) – the diet with 10% extract of balsamic poplar buds with activated charcoal (EG3). Supplementation of feed with balsamic poplar buds increased goat's milk productivity by 34.2% without compromising milk quality, which was evaluated by the amount of milk and contents of milk fat and protein. Supplementation of feed with balsamic poplar bud extract and activated carbon contributed to an increase in milk yield by 25%. Such, using phytobiotic feed additives is a promising method in animal husbandry.

The Ministry of Agriculture of the Republic of Kazakhstan and agricultural producers have been given a number of urgent tasks aimed at the production and export of livestock products (mainly meat and milk), as well as improving their quality and safety. The quality and safety of livestock products are the main indicators that determine its value and, to the greatest extent, depend on the feed used. The problem of full-fledged feeding of farm animals in recent years, in connection with the intensification of animal husbandry, is becoming increasingly important. It has been proved that it is important not only to meet the animal's needs for basic nutritional factors, but also the ratio of individual nutrients in the diet (sugar-protein, energy-protein, acid-base), the absence of anti-nutritional and toxic substances in feeds. The presented article provides overview literature data on the effect of the components of multifunctional feed additives on the animal organism, as well as on the quality and safety of products obtained from them. The use of additives can improve the general condition of animals, qualitative and quantitative signs of productivity, increase the safety of livestock, and also helps to prevent disturbances in energy metabolism.
