“…At the same time, normalized feeding on the basis of a comprehensive analysis of the chemical composition, a certain set and ratio of feed, as well as scientifically justified detailed norms and the balance of diets in them is a determining criterion for the realization of the genetic potential of animals with high productivity [8]. A number of works by domestic and foreign researchers were devoted to the study of fat rationing in feeding cattle.…”

The work is devoted to determining the optimal level of fat in concentrate-senage diets for high-yield cows and studying the effect of various levels of fat in the dry matter of the diet on milk productivity and chemical composition of milk. Studies have shown the insufficiency of household diets of highly productive cows with a dry diet content of 3.2% raw fat. This deterred the potential for dairy productivity. Addition of fat in cow diets by equivalent energy and protein replacement of a portion of the compound feed with a rapeseed cake up to a level of 4.2% of the dry substance provides an increase in milk productivity in relation to the control group receiving 3.2% fat. Optimization of the fat level in the dry substance of the diet up to 4.2% in the nutrition system of cows increases the functional activity of the breast in their body, which is expressed in the growth of breast productivity by 6.78%, improvement of the chemical composition and technological properties of milk. A further increase in dietary fat to 5.2% has a less pronounced effect on the change in milk productivity.

A key factor in realizing the genetic potential of animal productivity is their complete feeding, in the organization of which the leading role belongs to the intensive system of feed production and the feed industry including the development of different balancing additives. In highly productive herds it is most problematic to balance the rations of down-calving cows and after their calving, since there is a physiological limitation of feed consumption and as a result a lack of energy and nutrients. At this stage there is a negative energy balance. After calving (and in general during the period of increasing the milk yield) to achieve high milk yields it is necessary to provide animals with feed of increased energy value, such as concentrates. However, high consumption of concentrated feed leads to acidosis and other diseases, which is accompanied by a decrease in milk yield and fertility. Special feed supplies are required to replenish energy. Due to the relevance and practical significance of the issue we have carried out a research aimed at studying the effect of the energy additive Tirzana BSK on the productivity of Ayrshire cows. The results of research on the use of the energy energy additive Tirzana BSK during late dry period and during the period of increasing the milk yield for Ayrshire cows with the yield of 8800 kg per lactation have been presented in the article. It has been found that the introduction of Tirzana BSK contributes to increasing milk productivity, reducing expenditures of feed per unit of production and reducing the time from calving to effective insemination. It has been experimentally proved that it is more effective to use the additive from late dry period to the middle of the period increasing the milk yield, which determines an increase in milk yield by 12,4 %, a reduction in the duration of the open days period by 19 days, and the increase in the profitability of milk production from 25,1 to 31,7 %.
