Physiological role of minerals in the body of young cattle and their impact on the realization of the genetic potential productivity of animals

In physiological experiments on three groups of calves of black-motley cattle studied exchange of standardized macro- and micronutrients at different levels. It was found that the lowest rates of minerals was in group 1, in which the content of macro- and micronutrients in diet did not meet the existing standards. Milk yield per lactation heifers in experimental groups was 4528.8; 5145.0 and 5456.0 kg, indicating a manifestation of the genetic potential of productivity at the specified animal nutrition from birth to adulthood.
