Сравнительный анализ применения средств для обработки вымени в профилактике маститов и повышении качества молока коров

Abstract

Abstract. The aim of this study is to study the effectiveness of the use of various means for treating the udder of cows in order to prevent the incidence of mastitis and improve the quality of milk. Since in order to prevent the development of mastitis for a long time, it is necessary not only to destroy the disease itself and fight its symptoms, but also to take all kinds of measures to prevent the disease. Methods. To conduct a scientific and economic experiment, 4 groups were formed, of which 3 are experimental and 1 control, according to the method of pairs-analogs using a tethered method of keeping in stalls in all four groups. To treat the udder, agents based on iodine, chlorhexidine, chlorhexidine digluconate and probiotic bacteria were used. Results. The summer use of Priolit Vortex and Algavit Vortex in 1 experimental group showed a decrease in the number of mesophilic aerobic facultative anaerobic microorganisms in cow's milk from 200,000 to 97,000 CFU/cm3, which is 48.5 % less than at the beginning of the experiment. Treatment with disinfectants Priolit Vortex and Elovit Vortex in the 2 nd experimental group made it possible to reduce the number of mesophilic aerobic facultative anaerobic microorganisms by 68.4 %. The use of probiotic agents Skin Cleaner and PIP Cow Teat Cleaner for treating the udder of cows allowed to reduce the number of mesophilic aerobic facultative anaerobic microorganisms in the milk of cows in experimental group 3 from 180,000 to 110,000 CFU / in 1 cm3, which is 61.1 % less than the initial indicators. Somatic cells in the milk of cows of the 1st experimental group decreased from 750,000 to 120,000 in 1 cm3, in the 2nd experimental group the number of somatic cells decreased from 250,000 to 180,000 in 1 cm3, in the 3rd experimental group from 390,000 to 340,000 in 1 cm3. In the control group, an increase in the number of somatic cells was found by 84 %.
