摘要
通过雏鸭急性毒性、肉仔鸡饲养试验研究了蒙脱石在动物体内对黄曲霉毒素B1(AFB1)的脱毒效果和对动物健康与生产性能的影响。结果表明,每只雏鸭一次摄入16μg及以上AFB1时可出现急性中毒死亡。肉仔鸡摄入含AFB1 80μg／kg的饲料,1周后饲料报酬降低,但肝脏中无AFB1残留。蒙脱石能对抗AFB1对动物的急慢性毒性作用,减少动物急性中毒死亡率,恢复动物生产性能。在肉鸡日粮中添加0.5％的蒙脱石对鸡骨骼强度无不良影响,对鸡骨骼钙、磷、铜、铁、锌沉积无影响;使骨骼铅、氟沉积减少,骨骼锰含量降低。
The detoxification effects of montmorillonite to Aflatoxin B1(AFB1) contamination was studied with ducklings and broilers as the test animals. It is found that taking AFB1 16μg or more once could be lethal for ducklings, and that taking feed contaminated AFB1 at level of 80 μg/kg for one week leads feed efficiency decrease for broilers. Montmorillonite is effective to alleviate the toxic effect of AFB1 on ducklings and broilers, decreasing bird death rate and recovering bird performance. With montmorillonite at level of 0. 5% in feed, the broiler bone strength and the deposit of Ca, P, Cu, Fe, and Zn in bone are not affected, the deposit of Pb and F in bone reduced, but the Mn content in bone is lower.
