为探讨不同吸附剂对霉变饲料的脱毒效果,将脱霉素、葡配甘露寡糖(EMG)分别与黄曲霉毒素B1(AFB1)及呕吐毒素(DON)按不同配比加入锦鲤的基础日粮,分两组饲喂360条锦鲤,40天后测定锦鲤血清谷丙转氨酶(ALT)和谷草转氨酶(AST)活性、总蛋白(TP)和白蛋白(ALB)水平及肝脏与体重比。结果表明:各组锦鲤血清中TP和ALB浓度均无显著(P>0.05)变化;脱霉素显著(P<0.05)抑制了高浓度DON条件下锦鲤的肝脏与体重比;AFB1显著(P<0.05)提高了AST、ALT活性,高剂量DON显著(P<0.05)提高了AST活性;两种吸附剂均能在一定程度上抑制AST、ALT活性升高,且EMG的效果要优于脱霉素。这表明脱霉素和EMG能有效缓解AFB1和DON导致的锦鲤肝功能损伤。
In order to explore the detoxification effect of different adsorbents on mildewed feedstuffs, different concentrations of streptomycin, glucomannan oligosaccharide (EMG) and aflatoxin B1 (AFB1) and DON were added into Koi The basal diet was fed on 360 koi carps in two groups. Serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) activities, total protein (TP) and albumin (ALB) ratio. The results showed that there was no significant difference (P> 0.05) between the concentrations of TP and ALB in the kiwifruit of each group; the ratio of liver to body weight of the koi carp was significantly inhibited by the streptomycin (P <0.05); AFB1 was significantly P <0.05) increased AST and ALT activity, high dose DON significantly (P <0.05) increased AST activity; both adsorbents to a certain extent, inhibited AST, ALT activity increased, and EMG effect is better than Romycin. This indicates that scleroprazin and EMG can effectively alleviate the hepatic injury induced by AFB1 and DON in koi fish.
