dc.description.abstractThe paper highlights the results of a study on the combined use of the CattlePro Effect amido-vitamin-and-mineral complex and PassPro Ballans feed product in the diets of newlycalved high producing cows. The studies were carried out in the conditions of the Bolshevik collective farm of the Kalacheevsky district of the Voronezh region (Russia) according to the method of A.I. Ovsyannikov (1976) for three months after a 21-day equalizing period. During the course of the experiment, it was determined that the introduction of new feed additives into the diet leads to an increase in the consumption of dry matter by lactating animals by 1.0–6.2%. The basic fat content and protein content of milk was increased by 11.6–19.1%, and when adjusting the milk yield for 4% milk – by 9.3–17.4%. The digested feed particles in the feces were closer to normal in the cows of the experimental groups, which indicates the beneficial effect of the feed additive on the digestive processes of animals. When applying the studied feed additive, there was a certain decrease in enterobacteria and staphylococci in the samples of the rumen fluid and at the same time there was an increase in lactic acid microorganisms 1.6–2.0 times.eng
