中文摘要:

      ［目的］探究不同脱霉产品对西门塔尔肉牛生长性能、免疫性能及组织霉菌毒素残留的影响。［方法］试验对60头353kg左右西门塔尔肉牛饲喂不同脱霉剂后的生长情况、血清生化指标和抗氧化指标、肌肉组织和肝脏中AFB1、ZON、DON残留含量结果进行分析。［结果］日粮中添加1g/kg解毒包处理料重比较对照组和脱霉剂组分别降低了4.34%（P<0.05）和4.10 %（P<0.05）；解毒包组ALT、AST、GR、GST、ADA酶活较对照组和脱霉剂组均有不同程度下降，总抗氧化能力（T-AOC）、活性蛋白酶（SOD）、过氧化物分解酶（GSH-PX）较对照组和脱霉寄组有不同程度提高，血清中丙二醛（MDA）解毒包组较对照组和脱霉剂组降低了16.7%（P＜0.05)和11.8%（P＜0.05)；解毒包组肌肉中的AFB1、ZON、DON残留量比对照组分别下降了 63.04% 、10.55%和 16.64%，肝脏中的AFB1、ZON、DON残留量比对照组分别下降了9.26%、7.94%和34.04%。［结论］日粮中添加1g/kg解毒包在一定程度上改善了肉牛的生长性能，降低了料重比，提高机体的抗氧化能力并改善肝脏健康状况，同时降低了霉菌毒素在肌肉和肝脏中的残留。

英文摘要:

      [Objective]To explore the effects of different mildew removers on growth performance, immune performance and tissue mycotoxin residues of Simmental beef cattle.[Method]The experiment analyzed the growth status, serum biochemical indexes and antioxidant indexes, and residual contents of AFB1, ZON and DON in muscle tissue and liver of 60 Simmental beef cattle about 353kg after feeding with different mildew removers.[Result]Compared with the control group and the mildew remover group, the F/G of 1 g/kg Detoxible added to the diet decreased by 4.34% (P<0.05) and 4.10% (P<0.05)respectively;The enzyme activities of ALT, AST, GR, GST and ADA in the Detoxible group were decreased to varying degrees compared with the Detoxible group and the mildew removing group，The T-AOC, SOD and GSH-PX of the Detoxible group were increased to different degrees compared with the control group and the mildew removing group，Compared with the control group and the mildew removing group, the serum MDA in the Detoxible group decreased by 16.7% (P<0.05) and 11.8% (P<0.05)，Compared with the control group, the residual amounts of AFB1, ZON, and DON in the muscles of the Detoxible group decreased by 63.04%, 10.55% and 16.64%, respectively, and the residual amounts of AFB1, ZON, and DON in the liver decreased by 9.26%, 7.94%, and 9.26%, respectively.[Conclusion]The addition of 1g/kg Detoxible to the diet improved the growth performance of beef cattle to a certain extent, reduced the feed-to-weight ratio, improved the body's antioxidant capacity and improved liver health, while reducing the residue of mycotoxins in muscle and liver .
