Influence of biologically active compounds on milk production and metabolism of lactating cows

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.
