不同吸附剂对锦鲤饲喂霉变饲料的脱毒效果研究
首发时间:2011-05-30
摘要:为探讨不同吸附剂对锦鲤饲喂霉变饲料的脱毒效果,本研究将320条锦鲤用于两组试验,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,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:(1)各组锦鲤血清中TP和ALB浓度均无显著(P>0.05)变化;(2)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;(3) 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;(4)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。

Study on Detoxification Effects of Different Adsorbents on Fancy Carp Fed with Mould Feedstuff
Abstract:This study was designed to research the detoxification effects of different adsorbents on Fancy Carp fed with mould feedstuff. 320 Fancy Carps were used in two experiments, detoxifier, EMG with AFB1 and DON in different ratio were added in basal diet respectively, the activity of ALT and AST, the levels of TP and ALB, and the ratio of liver weight and body weight were determined at 40th day. The results showed that: (1)the levels of TP and ALB were not changed significantly in all groups(P>0.05); (2)detoxifier inhibited the weight gain of liver in condition of DON in high level(P<0.05); (3)AFB1 increased the activity of AST and ALT significantly(P<0.05), and DON in high level increased the activity of AST significantly(P<0.05); (4)the two adsorbents inhibited the increased activity of AST and ALT to some extent, and the effects of EMG were better than detoxifier. It was indicated that EMG and detoxifier could attenuate the liver function disorder caused by AFB1 and DON in Fancy Carp.
