Abstract
When applying hygiene products «Gikor-D» and «Hamra Blue» before and after milking on the udder in the milk of cows no excess of safety indicators was detected. At the same time, disinfectants provided protection of the udder and breast nipples from contamination by pathogenic microflora. In cows, that were treated with disinfectants based on chlorhexidine bigluconate during lactation, there is a positive correlation between the number of somatic and of mesophilic cells aerobic and facultative-anaerobic microorganisms in milk. Indicators of density, CFR, fat, SOMO and caloric content of milk after the use of disinfectants are higher than without their use. There are no significant biochemical changes in the milk of cows, therefore, the use of disinfectants before and after milking of cows does not worsen the quality of milk, and also protects the udder and breast nipples from disease during lactation.
