Influence of disorders in the biochemical profile of the blood of pregnant cows on the incidence of their ketosis

The aim of the research was to study the relationship between violations of the biochemical profile of the blood of pregnant cows on the incidence of their ketosis. In the body of the breeding stock, disturbances in protein, fat, carbohydrate and mineral metabolism were detected: a decrease in the level of total protein, cholesterol, triglycerides, glucose, calcium and phosphorus. Enzymatic activity was characterized by an increase in alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and alpha-amylase. In the body of pregnant uteruses, a deficiency of carotene was observed and the buffer capacity of the blood plasma was weakened. It was established that in freshly calved cows with impaired biochemical blood parameters, out of 18 queens, 6 females suffered from a subclinical form of ketosis, two had clinical manifestations of the disease.
