The 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.
