O ne of the major challenges of developed dairy farming worldwide is to increase the productivity of cows and to improve nutritional and sanitary qualities of milk (

During the experiments, it was found that the latent period of the breast-feeding reflex is 22.8% less, the milking time is 10.8% less. The average milking intensity increases by 22.7%, intravenous pressure - by 19.4%, with an increase in single milk yield by 15.3%. The concentration of Staph. aigees, Strep. agalactiae, was lower when the nipples were immersed in a solution of hygiene products "Chlorhexidine bigluconate-aloe" and "Teasfoam Supercow-olive oil" before and after milking, compared with untreated nipples. Controlled treatment of the udder nipples and mammary gland with the hygienic product "HGB aloe" before and after cow milking with high milk yields in 2.4% of animals prevents hyperkeratosis of the udder nipples and in 12.1% subclinical mastitis, against 5.4% heperkeratosis and 26.5% subclinical mastitis of control groups of dairy cows. Using hygienic products, an increase in milk yield in cows is provided by 18.45...22.0%, and the functioning of the udder by 16.45...26.34 %. To improve the functioning of the udder during lactation in cows, hygiene products "Chlorhexidine bigluconate-aloe" or "Teasfoam Supercow–olive oil" should be used to treat the udder nipples before and after each milking.
