IMMUNOLOGICAL STATUS OF BLOOD AND MILK OF COWS AFTER APPLICATION OF PROBIOTICS

Among the main tasks of cattle breeding is creation of conditions for obtaining healthy young animals, which will ensure high level of productivity in the future. Nowadays, interest in probiotic products is growing in countries around the world. Probiotics help to reduce diseases of livestock, improve digestion, metabolism, increase animal productivity, and maintain the immunological status. Vetom series probiotics are widely used in this industry. These products have an extensive range of actions, one of which is correction of immunobiochemical status. The aim of our study was to study the effect of Vetom 1.2 probiotics on immunological status of blood and milk. Scientific and economic experiment was carried out at AO "Uchkhoz" Prigorodnoe ", Barnaul, on black-and-white cows in the autumn-winter period. The manufacturer of "Vetom 1.2" probiotic preparation is OOO NPF "Research Center", Novosibirsk Region, Koltsovo v. When analyzing the results of the studies, we found: 1. Increase of parameters during the study period: carotene by 27.4%, retinol and tocopherol by 26.5% and 16.2%, respectively, gamma globulin by 15.8%, albumin by 10 .6%. 2. Increase of immunoglobulins in blood serum of cows in the experimental group compared to the control group: albumin by 14.4%; alpha, beta, gamma globulin by 16.3%, 13.7%, 17.8%, respectively. 3. It was found that the level of immunoglobulins in colostrum was higher by 31.4% in the experimental group of cows on the first day of lactation, on the second day by 14.1% compared to the control group. Based on the obtained results, the following conclusions were made: 1. "Vetom 1.2" has a positive effect on dynamics of immunological status of cow blood. 2. The probiotics helps to increase the level of immunoglobulins in the colostrum of cows.
