The diseases of the metabolism of cattle connected with defective feeding

In the article the results of dairy cattle’s blood of different age and production groups of biochemistry research in the conditions of the Amur region are stated. The biochemistry of calves’ blood indicated the metabolic disorder caused by toxic dyspepsia. The low level of glucose, albumine and aminotransferases, high level of bilirubin, triglycerides and cholesterol at dairy cows showed the violation of carbohydrate, proteinaceous, lipidic and fermental metabolism and pathology of a liver. The violation of phosphoms-calcium balance and high level of alkaline phosphatase at dairy cows and heifers indicated violation of a mineral exchange.
