摘　　要：试验旨在探究银耳副产物对小鼠生长状况、肝脏功能、免疫功能及耐力的影响。取3种银耳副产物,分别设置低中高剂量组,记录各组小鼠生长状况指标,测定免疫功能性指标、肝脏功能性指标,通过游泳试验建立动物疲劳模型,探究饲料对小鼠耐力影响。结果表明,菌糠低剂量组、蒂头料低剂量组能够不损伤小鼠的肝组织,促进小鼠生长发育,其中菌糠低剂量组、菌糠中剂量组及蒂头料低剂量组小鼠平均日增重比对照组提高14.52%、11.29%、14.52%。菌糠的低、中剂量组以及蒂头料的低、中剂量组小鼠乳酸脱氢酶活性极显著提高(P<0.01),血清尿素氮含量极显著降低(P<0.01),从而提高小鼠耐力。研究表明,添加一定剂量银耳菌糠或银耳蒂头料作为饲料辅料,可在不影响肝脏功能的前提下促进小鼠生长、提高小鼠免疫力及耐力。The experiment was to study the effects of Tremella fuciformis by-product on the growth status,liver function,immune function and endurance of mice.Three kinds ofTremella fuciformis by-product were taken and low-mediumhigh dose groups were set respectively.The growth status indexes of mice in each group were recorded,and the immune functional indexes and liver functional indexes were determined.The animal fatigue model was established by swimming experiment to explore the effects of feed on the endurance of mice.The results showed that the low-dose fungus bran group and low-dose fungus bran group could not damage the liver tissue of mice and promote the growth and development of mice.The average daily gain of mice in low-dose fungus bran group,medium-dose fungus bran group and low-dose fungus bran material group was 14.52%,11.29%and 14.52%higher than that in control group.The activity of lactate dehydrogenase was extremely increased(P<0.01)and the content of serum urea nitrogen was extremely decreased(P<0.01),and the endurance of mice was increased.The experiment indicates taht using the bran or pedicle of Tremella fuciformis as feed excipients can promote mouse growth performance,improve immunity ability and endurance without affecting liver function.
