摘要 选择21d健康的100只雄性昆明小鼠,随机分为5组,1组为空白对照组,饲喂基础日粮;2组为阳性对照组,在基础日粮中添加2mg/kg呕吐毒素(DON);3~5组为试验组,每组在添加2mg/kgDON的基础日粮中分别添加0.05%、0.10%和0.15%的酯化葡甘露聚糖(EGM)。研究DON染毒饲料中添加EGM对小鼠生理和免疫指标的影响,结果表明,试验至30d,1组、4组和5组平均日增质量及脾和胸腺指数显著高于2组;血液红细胞数量、白细胞数量、血红蛋白含量和淋巴细胞转化率极显著高于2组;2组肝指数极显著高于1组、4组和5组;1组、4组和5组各项指标差异不显著。由此表明,EGM能很好地吸附DON,减轻DON对小鼠的毒性损伤作用,在饲料中的最适添加剂量为0.10%。
