Fusarioses among pigs
Journal Title: Бюлетень "Ветеринарна біотехнологія" - Year 2019, Vol 35, Issue
Abstract
Introduction. Microscopic fungi can affect feeds at various stages of production and cause animal mycotoxicoses. The presence of mycotoxins in feeds even in trace amount can lead to considerable losses due to reduced productivity, decreasing of reproducing function and immune reactivity of an organism. T2 toxin and zearalenone importance toxin that contaminate feeds are of considerable, which are producers of Fusarium fungi. The goal of the work. lies in diagnosis of fusariosis (zearalenone and T2 toxin) among pigs through mycotoxicology study of feeds. Materials and methods. In this research 5 feed sample which from a private pig farm in Cherkassy region were used: 1-bran; 2-corn; 3-soybean meal; 4-sunflower meal; 5-wheat. Spore contamination with micromicytes and determination of the mycotoxins existence were availability studied. Results of the study and discussion. In the pig farm during the clinical examination of pigs a massive reddening and swelling of pigs vulvas were observed, redused growth and development, feed intake and difficulty of swallowing as well. Discovered clinical signs were similar to described in case of zearalenone and T2 toxicosis in pigs. We conducted mycotoxicology studies of feeds to confirm the diagnosis. As a result of our investigations of 5 different feed sampls we established that spore contamination of feeds with micromicytes exceeded the maximum levels by several times. Such spore contamination of feeds with micromicytes redused their quality and can cause diseases in animals such as mycotoxicoses that lead to weakening of animals organism’s immune resistance and emerging of infectious diseases. Conclusions and prospects of further research. During researches on mycotoxins availability, zearalenone and T2 toxin were found in all sampls except the corn in a quantity that exceeded maximum permissible levels of mycotoxins in feeds that were within 0,25 - 5 mg/kg of feed. Thus, zearalenone and T2 toxicosis of pigs were confirmed were found among pigs. It is recommended to carry out decontamination of feeds and to add sorbents to the pigs diet.
