Journal Title: Бюлетень "Ветеринарна біотехнологія" - Year 2018, Vol 32, Issue
Abstract
Introduction. Complete feeding of animals is an important factor in the successful development of animal husbandry. Provision of livestock with high quality fodder grain is of great importance. Toxigenic molds and their metabolites affecting fodder, cause in animals and poultry complex poisoning of varying levels from acute to chronic. At the same time there is a decrease in productivity, deterioration of sanitary quality of products, decrease in resistance and immune status and, as a rule, increase in the incidence of infectious and non-contagious etiology. The goal of the work was to confirm the diagnosis of mycotoxicosis in pigs by identifying fungi in feeds, establishing their species toxigenic characteristics and the number of detected mycotoxins. Materials and methods. An outbreak of an unidentified etiology in the pig farm with suspicion on the mycotoxicosis has been detected. Seven samples of feed were selected for the mycotoxicological researches: corn, wheat, soybeans, barley, oats, bran. Sampling of grain for mycological research was conducted based on the guidelines for sanitary-mycological evaluation and improvement of feed quality. Results of the study and discussion. During the general examination of pigs mass reddening and vulva swelling were observed. According to organoleptic parameters corn was suspected to be contaminated with Fusarium fungi. In mycotoxicological researches of fodder, 28 strains of fungi were isolated and identified. Fungi strains of the genus Fusarium were the most numerous - 32.1%. Fungi of the genus Penicillium were isolated in 21.4% of cases, Aspergillus genus fungi in 14.3%. The mixed fodder was contaminated with aflatoxin B1 in concentration 0.1 mg/kg, zearalenone in 2 mg/kg. Conclusions and prospects for further research. As a result of the animal studies, the diagnosis of zearalenotoxicosis was confirmed. In order to prevent the mycotoxicosis of animals, it is necessary to conduct routine monitoring studies of feed on the presence of fungi.
