USE OF BACILLUS PUMILUS FOR PREVENTION OF KETOSIS IN COWS

Abstract

The paper considers the effectiveness of Bacillus pumilus (109 CFU / g) for dairy cows for the treatment and prevention of ketosis. The causes of ketosis in the farm were also studied. The research was conducted in LTD "Agrofirma Lan", v. Kindrativka, Sumy district, Sumy region. Healthy and ill on ketosis cows were used for the experiment. The total number of experimental animals was 15 heads. Animals with ketosis received compound feed with the addition of Bacillus pumilus (109 CFU / g) at a dose of 15-35 g per animal. Healthy cows in the control group had a normal diet for their production group. The studies were performed for 30 days. The aim of the study was to investigate the mechanism of acetonemia in farm animals and to determine the effectiveness of Bacillus pumilus (109 CFU / g) in ketosis of dairy cows. During the study it was found that cows at different times of the year productivity was largely related to the way they were kept. Thus, in the warm season, cows with an average daily milk yield of more than 35 kg and younger cows of the first lactation had better clinical indicators compared to other animals. According to the results of the studies, it was found that the level of urea and urea nitrogen in the cows of the experimental group before treatment was 77.8 % higher than in healthy animals in the control. Aspartate aminotransferase (AST) at the beginning of the study in cows with ketosis was 78.8 % higher than in healthy animals. An increase in the level of this metabolite in the blood indicates liver damage and increases and decreases simultaneously with urea and β-ketones in the blood of sick animals. In addition, serum protein levels, including globulins and albumins, in experimental and control cows were within the reference value for cows throughout the experimental period. Feeding cows that ill on ketosis Bacillus pumilus (109 CFU / g) at a dose of 35 g per animal helps to reduce serum β-ketones and return to physiological norm. The use of probiotic strain Bacillus pumilus does not cause toxic effects on organs and systems of the body. Contributes to the normalization of metabolic processes in the body.
