Corn purposely infected with Fusarium graminearum was found to contain 800 to 900 mg vomitoxin/kg. Contaminated corn was substituted for control corn at 0, 6, 12, 18, and 24% in a corn-soybean meal ration. Broiler cockerels were given each experimental diet from 6 to 11 days of age; then sample groups were necropsied. Remaining birds were subsequently offered commercial starter for 2 days and sample groups again necropsied. Growth and diet consumption were not significantly reduced until contaminated corn exceeded 12% of the ration (116 mg vomitoxin/kg). Alertness, coordination, and feathering appeared normal regardless of treatment. Birds that received contaminated corn exhibited plaques in the mouth and gizzard erosions proportional to the level of substitution. All lesions were generally restricted to the epithelial layer and no liver or kidney involvement could be demonstrated. A short return to uncontaminated feed eliminated most lesions. Fowl appear to be considerably more tolerant of vomitoxin than swine.
故意感染禾谷镰刀菌的玉米被发现含有800至900毫克呕吐毒素/千克。在玉米 - 豆粕日粮中，用受污染的玉米替代对照玉米，替代比例分别为0%、6%、12%、18%和24%。从6日龄到11日龄，给肉用小公鸡投喂每种实验日粮；然后对样本组进行剖检。随后，给其余的鸡投喂2天商业育雏料，并再次对样本组进行剖检。直到受污染的玉米超过日粮的12%（116毫克呕吐毒素/千克），生长和日粮消耗才显著降低。无论处理如何，警觉性、协调性和羽毛状况看起来都正常。摄入受污染玉米的鸡口腔出现斑块，肌胃糜烂，且与替代水平成比例。所有病变通常局限于上皮层，未发现肝脏或肾脏受累。短期恢复投喂未受污染的饲料可消除大部分病变。禽类似乎比猪对呕吐毒素的耐受性强得多。
