Digestibility of nutrients when using feed additives with amino acids and hepatoprotector in the diets of lactating cows

Increasing the productivity of cattle is possible only with the use of highly effective feed additives in the diets that help to level the imbalance of nutrients and energy, which is especially important when organizing the feeding of highly productive animals. The maximum consumption by cattle of diets balanced in basic nutrients contributes not only to an increase in animal productivity, but also to an increase in the efficiency of milk production in general. The organization of balanced feeding involves the fullest use of the nutrients of the diet by improving its digestion by animals. In addition, the achievements in the modern breeding process to date have led to the fact that the genetic potential of cattle significantly exceeds the physiological ability of animals to consume a sufficient amount of feed for its realization. This leads to metabolic disorders, a significant part of which, against the background of high productivity, is manifested by a negative energy balance, especially in the new-body group and in the first months of lactation. The imbalance of energy and nutrients in the diets further aggravates the situation, contributes to a long-term metabolic disorder, and, as a result, the occurrence of various dysfunctions, as well as a reduction in the productive longevity of animals. The article presents the results of studies on the digestibility of nutrients when feed additives based on modified zeolite enriched with a complex of protected amino acids and a hepatoprotector are included in the diets of lactating cows.
