Milk quality and dynamics of productivity of cows when using probiotics and zeolite in diets

The purpose of this work is to assess the quality of cows' milk when using activated zeolite and probiotics Klyuver Pro and Provitol as part of the diet, as well as to analyze the dynamics of milk productivity of cows when they are fed during the height of lactation. The use of the studied feed additives in the composition of the feeding rations contributed to the production of milk with optimal organoleptic indicators. The use of activated zeolite with yeast probiotic Klyuver Pro in cow diets is accompanied by an increase in the mass fraction of fat in milk by 0,13 %. The maximum increase in the mass fraction of protein in milk was observed when cows were fed diets with activated zeolite and phytoprobiotic Provitol - 0,11 %. The use of zeolite in combination with probiotics can increase the milk production of cows. On average, over the entire period of research, the milk productivity of cows in the second group exceeded the values in the control by 12,41 %, while in the individuals of the third group it was 12,97 % higher than in the control.
