This article presents data on the effect of chelates Cu, Zn, Mn, and sulfates on the quality and safety of cows’ milk. It is shown that the compensation of the lack of trace elements in the diet by 50%, and the additional use of vitamin E in an amount of 400 mg/head/day, increasing the fat content contributed 7,0% protein and 2,12 to decrease the level of somatic cells at 22,86% of cows milk. the research groups chelates trace elements Сopper, Zinc, Mangane and vitamin E as contributing to the overall average daily milk yield on 3-month lactation cows in the experimental group at 6,43%, in contrast to the control group. Analysis of the data shows that the natural fat content milk yield for the entire period of the experiment was higher at 6,65% in the experimental group of animals compared with control.
The additional introduction of experimental diet deficient cows the mixed trace elements Copper, Zinc and Mangane in the form of sulphate salts and their compounds in the form chelate complex with Vitamin E content of these elements in milk cows all groups had no significant difference and ranged maximum permissible concentration.
Key words: vitamin E, milkcows, chelates, performance, traceelements, somaticcells.
