Safety and quality of pork products using complex disinfectants

Disinfection, both today and in the past, is an integral part of the complex of sanitary and veterinary measures aimed at preventing new diseases; blocking, preventing the spread and, if possible, eliminating existing diseases; reducing the pressure of pathogenic, conditionally pathogenic or saprophytic microflora on productive animals throughout the entire production cycle, and especially during its critical periods. The purpose of the study is to assess the safety and quality of pig products (chemical composition and physical and technological properties of pig meat) using complex disinfectants. Research materials. The studies were carried out during 2022–2023 in the scientific research laboratory "Veterinary and sanitary examination of livestock products" of the Department of Veterinary and Sanitary Examination, Hygiene of Livestock Products and Pathology named after Y.S. Zagaevskyi of Bila Tserkva National Agrarian University and the certified laboratory of the Department of Veterinary and Sanitary Examination and Laboratory Diagnostics of the Institute of Veterinary and Sanitary Examination of the State Institute of Veterinary Medicine of Bila Tserkva National Agrarian University. Experimental experiments and scientific and practical observations were carried out in the conditions of AF LLC "DIM" - a pig farm in the Bila Tserkva district of the Kyiv region. Research methods: analytical, physical, morphological, biochemical, organoleptic, veterinary and sanitary and variational and statistical. As a result of the research, it was found that when using complex disinfectants, the air temperature in the control and experimental premises of the pig farm was observed within 18.50±3.16–20.50±2.36 ºС. Relative humidity ranged from 70.24±5.16 to 74.20±5.12 %, which corresponds to the norms of the State Standard for Animal Husbandry. Minor moisture condensation was observed on the walls, ceiling and enclosing structures. When studying the microclimate in the control and experimental rooms, it was found that the hygienic indicators practically did not differ. The disinfectant "Multiclin Aqua" at a concentration of 0.25 % has a bactericidal prolonging effect compared to the drug "Ecocid C" at 1 %. The use of the disinfectant "Multiclin Aqua" in experimental rooms does not cause a negative effect on the morpho-biochemical composition of the blood of animals. No diferences were found compared to animals in the control groups. At the end of the studies, the live weight of piglets during growth was significantly higher by 4.3 kg in the experimental groups. The average daily gain in the experimental groups of animals was 12.1% higher than in the control groups. In piglets of fattening age on the 180th day of the study, it was found that the average daily gain in the experimental groups was 12.7 % higher than in the control groups (p<0.05). The use of the disinfectant preparation "Multiclin Aqua" in the experimental premises did not cause a negative effect on the weight of the internal organs of pigs - the heart, lungs with trachea and kidneys, biochemical indicators of pig meat. The compar ative biological value (CVB) of pork for the use of ciliates infusoria Tetrahymena pyriformis showed a high biological value of pork obtained from animals of the experimental group (100.5 %). According to the main organoleptic, physicochemical indicators, fat obtained from carcasses of experimental and con trol groupsof animals did not differ significantly from each other both in a fresh state and after storage.
