A Field Investigation Of Zearalenone And Deoxynivalenol Pollution In The Common Used Feedstuffs

Mycotoxins are secondary metabolites of mould. The mycotoxin pollution could reduce the value of the feed stuffs. The livestock growth performance would be negatively affected. Mycotoxins also have the adverse effect on animal health and body function. Sometimes mycotoxins are lethal. Feedstuffs such as corn, wheat,rice are widely troubled with mycotoxins. The common toxins include Aflatoxin B1, deoxynivalenol,trichothecene mycotoxins, ochratoxin, fumitremorgin, zearalenone.In the current research, we investigated some feedstuffs(corn, wheat, corn derivatives such as DDGS, corn germ meal, and some oil cakes). All the feedstuffs were from local commercial feed company. The corn and wheat were from all over the mainland. The corn-derivatives and oil cakes were bag packaged. The zearalenone and deoxynivalenol were determined with ELISA method.The results of our study indicated that mycotoxins pollution were related to temperature and humidity.Higher temperature and humidity lead to higher pollution. The pollution degree also related to season. Some relationship was found between different mycotoxins. A similar pollute curve was found in zearalenone and deoxynivalenol.The content of zearalenone and deoxynivalenol was the highest in corn-derivative feedstuffs. The pollution of zearalenone and deoxynivalenol in corn was also common, especially for zearalenone. The dominant pollution in wheat was deoxynivalenol. On the contrary, oil cakes showed less pollution of these two mycotoxins.In conclusion, the mycotoxin pollution is a threat to animal and human health and economy development.Our research provided some fundamental data for the control of mycotoxin pollution in feed industry.
