霉菌毒素在发酵全混合日粮中的动态变化研究

Study on dynamic change of mycotoxins in fermented total mixed diet

试验为研究发酵全混合日粮霉变过程中霉菌毒素的变化规律,采取人工辅助的方法促使饲料霉变,测定其中玉米赤霉烯酮(ZEN)、T-2毒素(T-2)、黄曲霉毒素(AFT)、呕吐毒素(DON)和伏马菌素(FB)含量,分析5种毒素之间的互作效应。结果显示,ZEN、T-2、AFT、DON和FB之间的关系以负相关为主;FB_(1)与T-2之间具有相互促进繁殖的作用;FB_(1)与AFB_(1)、DON与AFB_(1)之间具有相互抑制繁殖的作用。研究表明,试验结果有助于有效预防和清除饲料中的霉菌毒素,为维护动物健康、提高经济效益提供技术参考。

The experiment was to study the changes in mycotoxins during the moldy process of fermented whole mixed diets.An artificially assisted method was used to promote feed moldy growth.The content of ZEN,T-2,AFT,DON and FB was measured,and the interaction effect between the five toxins was analyzed.The results showed that there was mainly a negative correlation between ZEN,T-2,AFT,DON and FB.FB_(1)and T-2 could promote the propagation of each other.FB_(1)and AFB_(1),DON and AFB_(1)had a mutually inhibitory effect on reproduction.The study indicates that the experiment is helpful to prevent and remove mycotoxins in feed effectively and provide technical reference for maintaining animal health and improving economic benefits.
