摘　　要：[目的]研究杏鲍菇菌糠的营养价值及羊日粮饲喂效果。[方法]对杏鲍菇菌糠和发酵杏鲍菇菌糠的营养成分进行了测定,并与几种非常规饲料进行了比较,设计了不同添加比例菌糠或发酵菌糠的全混合日粮(TMR),分别在波尔杂交公羊育肥期和湖羊母羊育成期进行了饲喂试验。[结果]杏鲍菇菌糠的粗蛋白含量为12.06%,发酵后杏鲍菇菌糠的粗蛋白含量达13.41%,均高于油菜秸秆(3.28%)和金针菇菌糠(9.92%)。试验组Ⅰ和试验组Ⅱ波杂公羊育肥期的日增重(ADG)分别为188.70和186.79 g/d,高于对照组。育成期湖羊母羊的饲喂试验结果表明,干杏鲍菇菌糠(45%)组湖羊的日增重为118.11 g/d,低于中药渣组。[结论]杏鲍菇菌糠在羊日粮中可替代部分常规饲料,能显著降低羊的饲料成本,且发酵后的营养价值及饲喂效果较好,在波杂山羊育肥期发酵菌糠的适宜添加比例为50%。[ Objective ] To study the nutritional value and feeding effects of mushroom bran of Pleurotus eryngii. [ Method ] The nutritional components of mushroom bran of P. eryngii and fermented mushroom bran of P. eryngii were determined and compared with several kinds of non-conventional feedstuff. TMR adding with different proportion of mushroom bran of P. eryngii and fermented mushroom bran of P. eryngii were designed to make the feeding experiment on Boer male hybrid goats in finishing stage and Hu female sheep in growing stage. [ Result ] The content of crude protein in mushroom bran of P. eryngii was 12.06% , and the content of crude protein in fermented mushroom bran of P. eryngii was 13.41%, which were higher than that in rape straw （3.28%） and mushroom bran of Flammulina velutiper （9.92%）. The average daily gain（ADG） of Boer male hybrid goat in finishing stage in test group I and test group I] were 188.70 and 186.79 g/d respectively, which was higher than that in control group. The feeding test results of Hu female sheep in growing stage showed that ADG in mushroom bran of P. eryngii was 118.11 g/d, which was lower than that in herb residues group. [ Conclusion ] Mushroom bran of P. eryngii can replace the conventional feed partly and signficantly reduce the cost. And its nutritional value and feeding effects after fermentation were better. Appropriate proportion of fermented mushroom bran in finishing stage of Boer hybrid goat was 50%.
