中文摘要：本研究旨在评估不同来源：甘蔗(细胞壁,CW;干酵母,DY;自溶酵母,AY)和啤酒工业（部分脱水啤酒酵母，BY）的酿酒酵母(SC) 生物量(20.0 g/d)对每天饲喂480 µg黄曲霉毒素B1（AFB1）的奶牛的产奶量、脂肪及蛋白质百分率和分泌黄曲霉毒素M1（AFM1）的作用。研究表明工业发酵副产物，特别是CW 和AY，作为奶牛日粮的饲料添加剂，对减少牛奶中AFM1分泌具有良好的应用前景。
外文摘要：p received AFB1 from d 1 to 6, while the SC biomass was administered with the AFB1 bolus from d 4 to 6. Aflatoxin B1 or SC-based products did not affect milk production or milk composition during the experimental period. Aflatoxin M1 was detected in the milk from all aflatoxin treatment group cows, reaching maximum levels at d 3 and varying from 0.52 ± 0.03 to 1.00 ± 0.04 µg/L. At end of the treatment period, CW, AY, DY, and BY removed 78%, 89%, 45%, and 50% of AFM1 from the milk, respectively, based on the highest level found on d 3. Results indicate a potential application of industrial fermentation by-products, especially CW and AY, as a feed additive in the diets of dairy cows to reduce the excretion of AFM1 in milk.
