Abstract

The effectiveness of dairy cattle breeding largely depends on the intensity of use of the breeding stock. At the same time, the factor of the duration of economic use of animals is gaining importance, which affects not only the production economy, but also the improvement of stocks and breeds. The lifelong productivity, the quantitative and qualitative growth of the stock, the amount of capital investment in its formation and the efficiency of operation depend on the term for the productive use of cows. The terms of breeding and production use of animals are direct linked with the biologically possible longevity of each animal, in turn, the duration of the productive period of cattle is in the range of 12-17 lactations. The influence of feed on production is associated primarily with the level of digestion and assimilation. The digestive capacity of the digestive tract of animals can be improved by selecting the optimal ratio in the diet of rough, juicy and concentrated feeds, i.e. optimization of animal feeding types. We conducted an analysis of milk productivity in lactating cows, when using AVMC feed additive in the diet. The experiment was conducted in the conditions of the dairy farm of Biryuli CJSC of the Vysokogorsky District of the Republic of Tatarstan on three groups of lactating cows. For the experiment, 30 cows were selected, 10 in each Holstein black-and-white breed according to the principle of analogues. Studies have shown that AVMC with rapeseed oil seeds and AVMC with fus in the diet of lactating cows provided higher animal productivity and positively affected the chemical composition of milk.
