The effect of feeding Biotin and zeolite on the performance of rumen metabolism in steers during the growing period

Abstract

This article presents the results of a physiological experiment on 3 bulls-analogs with rumen fistulae to study the metabolic processes in the main part of the stomach when introducing a microbiological protein Supplement of biotrine and zeolite of natural origin into the main feeding diet. The balance of nitrogen and the main macro-and microelements was studied, and the hematological parameters of the blood of bulls during the growing period were studied. Based on the results obtained, it is recommended to use biotrin in the feeding diets of raised young cattle both separately and in different ratios with zeolite, which creates favorable conditions for fermentation and assimilation of feed nutrients.
