The public of our country makes ever-increasing demands on milk in terms of safety and nutritional values. In accordance with the requirements of the Interstate Standard GOST 31449-2013 “Raw milk of cow. Specifications” the number of mesophilic aerobic and facultative anaerobic microorganisms should not exceed 1.0×105 CFU/cm3, the number of somatic cells - 4.0×105 in 1 cm3 in milk. The dairy industry places high demands on milk quality, namely, on bacterial contamination. Dairy products of high quality can only be obtained from good raw materials. High bacterial contamination worsens the quality of raw milk and its processed products and creates a certain risk factor for human health. In the Chuvash Republic, studies were carried out on the use of modern domestic iodine-containing preparations and lactic acid-based preparations for the treatment of the udder of cows. At the same time, the sanitary-hygienic condition of the udder’s nipples was improved, the microbiological seeding and the number of somatic cells decreased, and the grade of milk of cows was increased. When treatment the udder of cows before milking by Violet and after milking by Lactovit, the number of mesophilic aerobic and facultative anaerobic microorganisms in milk decreased by 22.9 times, the number of somatic cells - by 2.0 times. When using Monklavit-1, the number of mesophilic aerobic and facultative anaerobic microorganisms decreased by 25.0 and the number of somatic cells decreased 2.5 times. It was found that the efficiency of Monclavit-1 using is higher 1.1 times according to the number of mesophilic aerobic and facultative anaerobic microorganisms and 1.5 times according to the number of somatic cells, than treatment of the udder of cows by Violet and Lactovite. The use of modern udder treatment means allowed to improve milk quality from the second to the highest grade.
