Correction of indicators of mineral and protein compounds metabolism in first-calf cows in the conditions of a biogeochemical province

In the presented work, monitoring of environmental objects was carried out, which allowed us to conclude that the land use area of a farm is a biogeochemical province, in which the content of essential trace elements has a deficient state with an excess of nickel salts. Comprehensive medical examination, morphobiochemical examination of blood convincingly indicates a change in the course of metabolic processes in first-calf cows. Significant changes in the blood undergo indicators of the metabolism of mineral and protein compounds that are significantly lower than the recommended reference values. The complex correction of the disturbed types of metabolism by introducing sunflower cake, the preparation Uberin and deficient trace elements into the diet contributes to the normalization of the studied indicators and against this background there is an increase in milk productivity.
