Biochemical indicators of calf blood milk period under the influence of probiotic Bacifolin

This article presents the results of the biochemical analysis of the blood serum of calves during the milking period, who received the probiotic preparation Bacifolin twice a day. To conduct the scientific experiment, two groups of calves of 5 days old were formed using the pair-analog method: a control group and an experimental group of calves of the Black-and- White Holstein breed. The experimental group of calves received Bacifolin at a dosage of 26 g daily for 30 days. According to the generally accepted methods, the indicators of waterelectrolyte, mineral, protein, carbohydrate, lipid metabolism and enzymes of transamination were determined in the blood serum, for which in calves at the age of 35 days old, blood was taken from the jugular vein before morning feeding. As the result of the research and analysis of the obtained blood serum samples, we noted an increase in such indicators as: phosphorus, chlorine, total calcium, total protein, albumins, globulins, glucose, lipase, amylase. The difference in these indicators was the following: phosphorus increased by 7.97%, chlorine increased by 5.29%, calcium increased by 2.29%, total protein increased by 5.39%, albumin increased by 1.29%, and globulin increased by 10.47%, as well as an increase in glucose concentration by 8.14%, lipase enzymes by 26.90%, and amylase enzymes by 20.83%, compared to the corresponding values in the control group. These changes indicate activation of metabolic processes in the body of dairy calves. Thus, the probiotic Bacifolin, which was fed to the calves, had a positive effect on the antioxidant and immune processes in their bodies.
