Abstract
Dairy farming is a strategic and most efficient branch of agriculture. Milk production depends on a number of factors. The practical experience of many scientists has shown that an increase in the milk productivity of cows is possible when the rations are fed in the form of complete feed mixtures (mono feed). Despite the fact that such a feeding technology contributes to an increase in milk productivity of cows, there are problems in the new calving period, related to their health. After calving, during the milking period, the cows lose their live weight, they quickly acquire metabolic disorders (liver steatosis, ketosis, acidosis, etc.). To prevent such pathological processes, it is necessary to feed energy-compensating supplements in the new calving period. One of the solutions of this problems is the inclusion of biologically active compounds in feed mixtures. In our research these are feed additives “Ecostimul-2” and “Active Mix". In the process of experimental studies, the effect of feed additives “Ecostimul-2” and “Active Mix” during their separate and joint feeding to lactating cows in the new calving period on their milk productivity and metabolism was studied. As a result of the experimental studies, it was found that feeding the used additives to cows in the new calving period promotes an increase in milk yield and a faster recovery of reproductive functions.
Highlights
At present, one of the main tasks of the agro-industrial complex is to meet the needs of the population in food products of the required assortment, high quality and at affordable prices
The aim of the research was to study the effect of Ecostimul-2 and Active Mix feed additives when fed separately and together in the diet of freshly calved cows on milk productivity, metabolism and reproductive indices
The live weight of cows at the beginning of the experiment did not differ between groups
Summary
One of the main tasks of the agro-industrial complex is to meet the needs of the population in food products of the required assortment, high quality and at affordable prices The solution to this problem is impossible without increasing the productivity of farm animals and can be carried out only with the organization of their full feeding. Based on the foregoing, given the lack of knowledge of these issues and the request of practice, the main task for specialists remains to understand these issues and correctly navigate which feed additives to use in their specific farms in order to balance feed rations The solution to this problem in modern conditions is relevant, and it can directly affect the economic performance of production
