The number of Clostridium botulinum type B organisms excreted by cattle fed brewers' grains in which these organisms were found to be present and the period for which they were excreted, were studied. Large numbers (10(5) - 10(7) per gramme) of these organisms were detected in the rumen contents and faeces of the animals. When feeding brewers' grains was discontinued, Cl. botulinum type B was still detectable in the faeces for a considerable period (greater than eight weeks). There was evidence to suggest that the number of Cl. botulinum organisms multiplies in the gastrointestinal tract of cattle.
对喂食酒糟且发现含有肉毒梭菌B型菌株的牛所排泄的该菌株数量及其排泄时长进行了研究。在这些动物的瘤胃内容物和粪便中检测到大量（每克10⁵ - 10⁷个）此类菌株。停止喂食酒糟后，肉毒梭菌B型在粪便中仍可检测到相当长一段时间（超过八周）。有证据表明肉毒梭菌在牛的胃肠道中会增殖。
