The effect of adsorbent and phytobiotic the density of diatomaceous fauna of the rumen and milk productivity of cows

Abstract

The aim of the work is to study the effect of adsorbent "Vermiculite" and phytobiotic "Extract Ruminant " on the density of infusoria fauna of the rumen and on the milk productivity of cows. The object of the research is lactating cows. As a result of the research it has been revealed that inclusion of adsorbent "Vermiculite" and phytobiotic "Extract Ruminant" in the diets of dairy animals had a positive effect on the density of infusoria in the rumen, having increased their number by 52.3 15.4% compared to the animals of the same age in the control group. The use of feed additives contributed to the increase in milk productivity of cows by 4.1 – 3.8% in the 1st and 2nd experimental groups, respectively.
