用天然脱氧雪腐镰刀菌烯醇(DON)污染的燕麦分级添加到混合饲料中，在生长猪中进行饲养试验。DON浓度分别为0、0.7、1.7和35 mg/kg。记录饲料消耗、体重增加、屠宰体重、生化和血液学指标包括血清免疫球蛋白A、临床情况和死后病理包括组织病理学。在整个试验期内，饲喂含3.5 mg/kg DON的饲粮组显著降低了体重，降低了屠宰体重和饲料利用率。在相同的DON浓度下，肝脏重量增加，血清蛋白和白蛋白浓度降低，红细胞压积、血清钙和血清磷暂时下降。饲喂含有1.7 mg/kg和3.5 mg/kg DON的饲料组，观察到每日饲料消耗量的统计上显著的剂量相关减少。没有记录到对血液学、生化或免疫学参数的其他影响。结果表明，日粮DON浓度为1.7 mg/kg时，对生长猪有显著影响，其来源为饲料中含有少量其他真菌毒素的自然污染的猫。
A feeding trial with naturally deoxynivalenol (DON)-contaminated oats included in feed mixtures at graded levels was conducted in growing pigs. The DON concentrations were 0, 0.7, 1.7, and 35 mg/kg of complete feed mixture given ad libitum to different groups. The data recorded were feed consumption, body weight gain, slaughter weight, biochemical and haematological data including serum immunoglobulin A, clinical condition and post-mortem pathology including histopathology.Significantly decreasing body weight pin throughout the experimental period, decreased slaughter weight and reduced feed utilization efficiency were observed for the group fed a diet containing 3.5 mg/kg of DON. At the same DON concentration, there were increased liver weights and decreased concentrations of serum protein and albumin, and a temporary fall in packed blood cell volume, serum calcium and serum phosphorus. For the groups fed diets containing 1.7 and 3.5 mg/kg of DON, a statistically significant, dose-related decrease in daily feed consumption was observed. No other effects on haematological, biochemical or immunological parameters were recorded. The carcass quality was not affected in any group.It was concluded that significant effects in growing pigs may be observed at a dietary DON concentration of 1.7 mg/kg, originating from naturally contaminated cats included in a diet that was otherwise adequate and contained only minor traces of other mycotoxins.
