Improvement of cow udder processing

Abstract

The paper is devoted to the study of the influence of the experimental preparation of the research and production company “Brovapharma” on the hygiene of the cow udder after milking. The research was conducted at the farm “Yekaterinoslavsky”, Dnipro city. For the experiment, two groups of cows with 14 animals each were formed. After milking, the cows of the control group were treated with the drug “Kenocidin” (Belgium), while the cows of the experimental group were treated with the experimental drug “Brovafarm”, which includes iodine. Individual milk samples were taken at the beginning of the experiment and on the eighth day after the weekly use of the drugs. Organoleptic, physicochemical, and bacteriological parameters of cow’s milk were determined. Before conducting the experiment, the sensitivity of microorganisms to the experimental preparation was determined by the method of serial dilutions in broth. The experimental drug in a dilution of 25.0–50.0% has antibacterial properties against Escherichia coli, Klebsiella pneumoniae, Proteus mirabilis, Shigella flexneri, Salmonella typhimurium, Pseudomonas aeruginosa, Enterococcus faecalis, Listeria monocytogenes, Staphylococcus aureus, Bacillus subtilis, Clostridium perfringens and Candida albicans. According to the research results, “Kenocidin” forms a blue film after processing the udder, which protects the teat canal from microorganisms. The experimental drug, which is brown in color and smells like iodine, forms a flesh-colored protective film, but it is difficult to see in a semi-dark milking parlor, so it is recommended to add a dye to improve visibility. Organoleptic indicators of milk (color, smell, consistency, and taste) from cows of the experimental group did not differ from those of the control group. The somatic cell count and the level of bacterial contamination of milk also remained unchanged, which indicates that the experimental drug does not negatively affect the quality and safety of milk and is no less effective than the drug «Kenocidin»
