Two trials utilizing two corn diets and four wheat diets were conducted. In Trial 2, all chicks were crop-infused at 9 d of age with Eimeria acervulina. In both trials, a broth culture of Clostridium perfringens was mixed with the diets for 3 consecutive d. Necrotic enteritis lesion scores were lowest in chickens consuming the corn diet with no C. perfringens and highest in chickens fed the wheat diets with C. perfringens. Chickens consuming a wheat diet with no added complex carbohydrates or added fiber exhibited the highest lesion score. Chickens on wheat diets with 4% new, ground, pine shavings had intestinal lesion scores intermediate to those of chickens that consumed the wheat or corn diets. Chickens consuming corn diets yielded the lowest lesion scores. Chickens provided diets containing either guar gum or pectin were not fully consumed and thus probably reduced the number of challenge organisms ingested.
进行了两项试验，一项使用两种玉米日粮，另一项使用四种小麦日粮。在试验2中，所有雏鸡在9日龄时嗉囊接种堆型艾美耳球虫。在两项试验中，产气荚膜梭菌的肉汤培养物与日粮连续混合3天。坏死性肠炎病变评分在食用不含产气荚膜梭菌的玉米日粮的鸡中最低，在喂食含产气荚膜梭菌的小麦日粮的鸡中最高。食用不添加复合碳水化合物或纤维的小麦日粮的鸡表现出最高的病变评分。食用添加4%新鲜磨碎的松木屑的小麦日粮的鸡的肠道病变评分介于食用小麦或玉米日粮的鸡之间。食用玉米日粮的鸡病变评分最低。提供含有瓜尔胶或果胶日粮的鸡没有完全吃完日粮，因此可能减少了摄入的感染微生物数量。
