Abstract
To date, there has been a significant increase in industrial pork production in Russia. Improving the survival and safety of piggies of different age groups is the most important task of veterinary medicine. However, despite the sufficient amount of antimicrobial drugs and specific therapy and prevention, the proportion of pig diseases is still quite high [8, 10, 11]. At the same time, multiple literary sources [1, 2, 3] say that the situation with contamination of feed and food raw materials with mycotoxins in Russia and in most countries is unsatisfactory.
Hence, the aim of the work was to determine the presence of mycotoxins in the feed supplied to pig farms and to study the effect of even insignificant concentrations of mycotoxins in feed on the morphological parameters of the blood of pigs of different age groups: the level of erythrocytes, leukocytes, hemoglobin, the percentage of lymphocytes and monocytes, the rate of erythrocyte sedimentation.
The research was carried out at one of the large pig farms in the North-Western region of Russia and at the Department of Pathophysiology of the St. Petersburg State Medical University.
As a result of the studies, the following effect of toxic feeds on the morphological parameters of suckling piglets, piglets on rearing and fattening piglets was established: erythrocytopenia, hypochromemia, leukopenia, a decrease in the percentage of lymphocytes, monocytes.
