Study On Detoxification Effects Of Different Adsorbents On Fancy Carp Fed With Mould Feedstuff

This study was designed to research the adsorptive capacity of detoxifier on aflatoxin and study on detoxification effects of different adsorbents on Fancy Carp fed with mould feedstuff. The experiment was divided into three parts:1.to research the adsorptive capacity of detoxifier in different levels on aflatoxin in different levels and probe the suitable dose of detoxifier in feedstuff contaminated by aflatoxin; 2.Combine the aflatoxin and different adsorbents in different proportions to study the effects on serum biochemical indices and liver weight of Fancy Carp; 3.Combine the vomitoxin and different adsorbents in different proportions to study the effects on serum biochemical indices and liver weight of Fancy Carp. The results showed that:1.The adsorptive capacity of detoxifier on aflatoxin(1)The adsorptive capacity of detoxifier added in 0.03% level on aflatoxin in 1 Oppb level was more than 80%, but about 60% merely on aflatoxin in higher lever;(2) The adsorptive capacity of detoxifier added in 0.06% level on aflatoxin in all levels were more than 80%;(3) The adsorptive capacity of detoxifier added in 0.09% level on aflatoxin in 50ppb level was more than 90%, and could up to 95%;(4) Detoxifier added in 0.06% level was suitable for feedstuff in medium quality and added in 0.06% level could guarantee the adsorptive capacity more than 80% on feedstuff in better quality.2.Effects of aflatoxin and different adsorbents on serum biochemical indices and liver weight of Fancy Carp(1)The effects of aflatoxin, detoxifier and EGM on activity of serum AST and ALT and liver weight were not significant(P>0.05); (2)The activity of serum AST and ALT could be lift by aflatoxin significantly(P<0.05);(3)Both detoxifier and EGM could inhibit the activity of serum AST and ALT in condition of aflatoxin, the inhibit effects of detoxifier on ALT and EGM on both of them were significant(P<0.05); (4)The effects of EGM were better than detoxifier.3. Effects of vomitoxin and different adsorbents on serum biochemical indices (1) The effects of DON, detoxifier and EGM on activity of serum AST and ALT were not significant(P>0.05), but detoxifier inhibited liver weight significantly (P< 0.05);(2) Activity of serum AST and ALT was not lift by DON in low level, but AST was inhibited by DON in high level significantly (P<0.05);(3)The activity of serum AST and ALT could not be inhibit by detoxifier in condition of DON in high level, but EGM could inhibit the ALT significantly(P<0.05);(4)The effects of EGM were good at serum biochemical indices and detoxifier were good at inhibit the liver weight.In summary, detoxifier could clean the aflatoxin in feedstuff effectively; The effects of detoxifier and EGM on inhibit the activity of AST and ALT and liver weight were significant, but could not solve the problem totally.
