摘要
为了研究生物脱霉剂的脱霉效果,本试验测定了生物脱霉剂对黄曲霉毒素B1的吸附强度,同时采用全收粪试验检测了霉变饲料添加生物脱霉剂后,家畜粪便中黄曲霉毒素B1的排出率。结果表明,将黄曲霉毒素B1的浓度调整为2μg/g时,添加1.2‰的生物脱霉剂,可吸附98.34%的黄曲霉毒素B1,全收粪试验表明,在霉变饲料中添加1‰的生物脱霉剂,被吸附的黄曲霉毒素B1随粪便的排出率为50.44%,添加2‰的生物脱霉剂,黄曲霉毒素B1的排出率为72.30%。
The afflatoxin B, binding or degrading ability of the biological mycotoxin removement agent was studied, and the ratio of the afflatoxin B1 discarded with the feces compared to the total intaken amount was also detected.The result showed that,when adjusted the content of afflatoxin B1 in feed to 2 μg/g and added 1.2 ‰ biological agent in vitro, 98.34 % afflatoxin B1 was removed efficiently.When added 1‰ biological agent,50.44 % afflatoxin B1 was discarded with the feces,while added 2 ‰ biological agent,72.30 % afflatoxin was discarded efficiently with the feces.
