FEED ADDITIVE FOR OPTIMIZING RUMEN DIGESTION WITH ADDITION OF YEAST CULTURE AND METHOD OF INCREASING MILK PRODUCTIVITY OF COWS Russian patent published in 2024 - IPC A23K10/00 

FIELD: agriculture.

SUBSTANCE: invention relates to agriculture, namely to a feed additive for optimizing rumen digestion of highly productive cows in the first period of lactation, which is a composition on a zeolite basis, including magnesium oxide and sodium carbonate salt, and activated zeolite of the following mineral composition is used as the zeolite: 20–30% of clinoptilolite, 20–30% of montmorillonite, 28.0–36.7% of opal-cristobalite, 10.6–21% of calcite, 4.6–11.3% of quartz, sodium bicarbonate as sodium carbonate; feed the additive additionally includes “И-Сак1026”, and the composition of the feed additive is characterized by the following ratio of components, wt. %: 64 of activated zeolite, 16 of sodium bicarbonate, 16 of magnesium oxide, 4 of Preparation “И-Сак1026”. The invention also relates to a method of increasing the milk productivity of cows, including feeding highly productive cows in the first period of lactation with the specified feed additive, and the feed additive is fed in a daily dose of 300 g per head.

EFFECT: use of the additive and a method according to the invention makes it possible to optimize the rumen environment for microflora, and optimization of the rumen environment increases the milk productivity of cows, leads to an increase in average daily milk yield by 13.8% and the yield of milk fat and protein by 16.5%.
