Thieu Nguyen Quang, a lecturer at the Department of Animal Nutrition, Faculty of Animal Science and Veterinary Medicine, Nong Lam University, Hochiminh City, Vietnam. At the Department of Animal Nutrition, he was responsible to give lecture of Animal Nutrition and Toxicology in feed. His researches is focusing on animal nutrition and mycotoxins in feed, and He has long time cooperated with feed mills and farms in Vietnam as consultancy.
In 1992, after received Doctor of Veterinary Medicine degree from Nong Lam University He was appointed as a researcher and lecturer at Department of Animal Nutrition in this University. The MSc degree was awarded by the Swedish University of Agricultural Sciences. In 2008, He was received the PhD degree with the research focus on mycotoxins in Vietnamese pig feeds by the Swedish University of Agricultural Sciences, Sweden.
Vietnam is a tropical country and the climate is tropical monsoonal, hot and humid. These climate conditions are create ideal environments for molds to develop and produce mycotoxins in agricultural products. Mycotoxins, which are secondary metabolites synthesized by a diverse number of fungal species, are toxic compounds that are known to produce a wide range of injurious effects on the health of humans and animals after acute or chronic exposure. Mycotoxins can be formed in the field during the growing season and increase during harvest, drying, storage or in transport and processing. Unfortunately, the contamination of foodstuffs and feedstuffs by mycotoxins is a worldwide problem and seems to be unavoidable, even though a considerable number of field and preservation studies have been done to prevent mycotoxins. Recent surveys have shown that feed ingredients and complete feeds are highly susceptible to aflatoxin, fumonisin and zearalenone. Today, due to the globalization of food and feed trade, the occurrence of any type of mycotoxin contamination is likely to be observed in Vietnam. At present, common mycotoxins in feed ingredients and complete feeds are: aflatoxin, ochratoxin, trichothecen, zearalenone, and fumonisin. In that, aflatoxin, fumonisin and ochratoxin originated in Vietnam, other toxins are mostly from temperate countries. However, some recent reports have found quite a lot of zearalenone and even deoxynivalenol on corn samples in Vietnam. This suggests that climate change may have influenced on the development of fungi and mycotoxin production in Vietnam and more research is needed to warn livestock producers and also feed producers.
