CURRENT TRENDS IN THE PREVENTION PROGRAM OF MAMMARY GLAND DISEASE AT COWS AND ASSESSMENT OF THEIR EFFECTIVENESS
Studying of the effectiveness of the probiotics use for the prevention of nipples and an udder diseases of cows held in 2012-2013 in the Sverdlovsk region's farms with different levels of milk production from 4960 to 8725 million kg. Probiotic agents were included in the existing farms in mastitis prevention programs instead of desinfectants on the basis of an iodine. The received results showed that the use of probiotic agents in the prevention of mastitis program allows you to maintain a normal state of health of the udder, as evidenced by the reduction of hyperkeratosis nipples of the breast to the level corresponding prosperous on hyperkeratosis and mastitis herd. Against application of probiotic products increases the number of cows without udder diseases (negative reaction with mastitis test) to 1.7-2.7 times, while reducing the number of animals that have positive and strongly-positive reactions in 1.3-3 times. The most expressed changes were noted by us in herds with lower milk production of cows, which is associated with a higher load on the tissue of the udder high yielding animals. When comparing the results of studies on the amount of milk somatic cells from the two groups of cows has been found that a group wherein 3 months probiotic agents used were detected 31.4 % of cows with somatic cells permanently located at less than 100 thousand/ml, 11.4 % of cows - the level below 200 thousand/ml and 17.1 % of the animals at a level below 400 thousand/ml. In group with use of iodinated means of animals with a fixed level of somatic cells less than 100 thousand/ml were not revealed. 25.6 % of cows had stable level of somatic cells less than 200 thousand/ml, and 12,8 % of the heads - it is lower than 400 thousand/ml. Regardless of the level of productivity was a significant reduction in the level of papillomatosis in the herd the 30 day use of probiotic products.
