Veterinary and sanitary examination pig slaughter products in the conditions of OAO “Velikoluksky Meat Processing Plant”

The article presents an analysis of the results of the veterinary and sanitary examination of pig carcasses. A conclusion is given on the suitability of the presented meat samples for consumption, as well as issues related to the peculiarities of veterinary examination of pig slaughter products for diseases of non-infectious etiology in the conditions of ОАО “Velikoluksky Meat Processing Plant”. Pathological changes in the products of pig slaughter caused by non-infectious diseases were detected after the internal organs were interned. In total, in May 2021 the slaughter products of 962 carcasses of pigs supplied to the slaughterhouse by healthy animals were examined. Mostly 6-8 month old gilts were slaughtered. During the observation period, various pathological conditions were revealed in the slaughter products of the pig herd. Analysis of digital material shows that the most common non-infectious pathology in pigs is pulmonary pathology, which was detected in 176 animals, which is 18.3% of the number studied. We associate the identification of a significant number of pigs with this pathology with long-term transportation. These animals need rest to prevent transport stress, but this is not provided in the conditions of the slaughterhouse. The nature of stress is indicated by such a pathological condition as a stomach ulcer, which was detected in pigs in 134 cases (12.3%). Diseases of the genitourinary system (nephritis) are registered next in the incidence of non-infectious pathology, which in total make up 11.11%. To a lesser extent, veterinary examination of pig slaughter products revealed such pathological processes, as kidney cysts (8.8%), peritonitis (9.3%) and liver cirrhosis (9%). The most common non-infectious pathology in pigs is pulmonary, which accounts for 18.3% of the studied slaughter products. Indicators of pre-slaughter weight of pigs and postslaughter weight of carcasses and organs of pigs with non-infectious pathology are significantly lower than in clinically healthy animals. According to the research results, it was found that the safety indicators in the studied meat samples correspond to the established standards.
