CLINICAL EVALUATION OF THE SUBSTANCE «GALF127KELMU1M2P» BASED ON POLYMER MATRICES WHEN USING THE GEA DairyProQ ROBOTIC MILKING SYSTEM

The research was carried out at the high-tech dairy enterprise "Russia" using the GEA DairyProQ robotic milking system of the Donskoye joint Venture of the Volgograd region. Experiments to study the effect of the substance "GALF127KELMU1M2P" have shown that the developed substance, according to the degree of exposure to the body of warm-blooded animals, belongs to low-hazard substances (hazard class 4 according to GOST 12.1.007-76). It has been proven that nipple treatment reduces the number of bacteria on the nipples and the surface of the breast, improves the sanitary quality of milk. The concentration of Staph. aigees, Strep. agalactiae, was lower when the udder nipples and breast surfaces were treated with the substance "GALF127KELMU1M2P" before and after milking, compared with untreated nipples and breast. Based on the results of the experiment, it can be concluded that the controlled treatment of the udder nipples and the breast surface with the substance "GALF127KELMU1M2P" before and after milking cows with high milk yields in 2.4% of animals does not prevent hyperkeratosis of the udder nipples. In addition, 12.1% are diagnosed with subclinical mastitis. As for the animals during disinfection of the udder nipples with Teasfoam Supercow, here hyperkeratosis of the udder nipples was noted in 3.3% of cows. Another 12.9% had sub-clinical mastitis. The results were as follows: hyperkeratosis of the udder nipples was diagnosed in 5.4% of cows. Another 26.5% of the animals became ill with subclinical mastitis. In cows of the control group, animals that did not use the drugs, inflammation of the skin of the udder nipples was noted on 34 nipples (30.4%) and inflammation of the mammary gland in 14 (12.5%) cows. The milk samples obtained from the treated nipples and breast during milking have no foreign smell, color and taste. There are no qualitative changes in milk samples obtained from cows whose nipples and mammary glands were treated during milking, so it can be concluded that the use of hygiene and disinfection of the mammary gland before and after milking cows does not change the sanitary and biochemical qualities of milk, as well as its technological properties.
