摘　　要：为了研究贝莱斯芽孢杆菌(Bacillus velezensis)对肉鸡生产性能及霉菌毒素含量的影响,采用ELISA试剂盒方法检测肉鸡临床试验粪便样品中黄曲霉毒素(AFB1)、伏马毒素(FB)、呕吐毒素(DON)和玉米赤霉烯酮(ZEN)的含量,并分析其对肉鸡生产性能的影响。结果表明:试验组(饮用水中添加200×1010CFU/t、100×1010CFU/t贝莱斯芽孢杆菌)肉鸡试验末平均体重显著大于对照组(P<0.05),试验组死淘率、料肉比显著低于对照组(P<0.05);试验Ⅰ组14~21日龄肉鸡粪便中黄曲霉毒素、呕吐毒素和玉米赤霉烯酮的含量均比对照组低。这说明添加贝莱斯芽孢杆菌(BLS-1)能够提高肉鸡的生长性能,降低料肉比及霉菌毒素代谢量,减少对动物机体的影响。In order to study the effects of Bacillus velezensis on the production performance and mycotoxin content in broilers,ELISA kit method was used to detect the content of aflatoxin(AFB 1),fumonisin(FB),deoxynivalenol(DON)and zearalenone(ZEN)in the fecal samples of broilers from clinical trials.The effects of B.velezensis on the production performance of broilers were investigated.The results showed that the average slaughter weight of broilers in the test groups(drinking water 200×1010 CFU/t,100×1010 CFU/t)was significantly higher than that in the control group(P<0.05),and the mortality and feed-meat ratio in the test groups were significantly lower than those in the control group(P<0.05).The contents of AFB 1,DON and ZEN in test groupⅠwere lower than that in the control group during the period of 14-21 days.The results indicated that the addition of B.velezensis(BLS-1)could improve the growth performance of broilers,decrease the feed-meat ratio and the mycotoxin metabolism,and further decrease the effects on the animal body.
