Adding natural zeolites, which are complex biogenic mineral additives, to the diet of dairy cows weakens the acidity, increasing the number of microfauna from 154.2 thousand to 196.2-225.0 thousand, increasing the number of volatile fatty
acids from 7.15 to 7.95-8.83 mmol / 100 ml. The development of the microbiological process increased the amylolytic efficiency of microflora from 8.8 mg to 11.6-15.9 mg / starch, and the cellulosaltic efficiency from 13.04 to 15.12- 17.84%. The amount of acetate directed to nafd milk formation increased from 56.2 to 59.2-62.0 mmol / l due to the gradual biodiversity of zeolite with the absorption of ammonia and gradual withdrawal to biodiversity, the share of microbial protein of biologically valuable from the total formed protein increased by 71.7% and amounted to 88.7±2.3 %. As a result, "raw" protein increased by 3.5-4.5%, and "raw" fiber-by 2.2-3.6%, the annual milk yield of cows increased from 3884-4152 kg to 3879±31.2 kg.
