METHOD FOR RAISING MILK PRODUCTIVITY AND QUALITY OF COW MILK UNDER CONDITIONS OF TECHNOLOGICAL POLLUTION OF ENVIRONMENT WITH LEAD AND ZINC COMPOUNDS

摘要

A method for raising the milk productivity and quality of cow milk under conditions of technological pollution of environment with lead and zinc compounds by means of correcting metabolism in the organism of lactating cows and normalizing the content of heavy metals in milk by additional introduction of natural adsorbents into feed rations.
