杏鲍菇菌糠配制波尔山羊全混合颗粒日粮的研究

Study on Mixed Feed of Boer Goat with Spent Mushroom Substrate of Pleurotuseryngii

本研究旨在分析和探讨利用杏鲍菇菌糠加工波尔山羊全混合颗粒日粮的可行性和效果。结果表明：菌糠经发酵处理后霉菌总数降低了62．9％，黄曲霉毒素减少了60．0％，呕吐毒素减少了44．9％，玉米赤霉烯酮未检测出；粗蛋白含量提高了11．98％，中性洗涤纤维和酸性洗涤纤维分别降低8.81％和11．69％；结果显示杏鲍菇菌糠经过发酵处理后主要卫生指标和品质得到显著提高，可作为养殖山羊的优质粗饲料使用。同时，对波尔山羊羔羊生长性能和血液生理生化指标的分析结果还表明，在配合日粮中杏鲍菇菌糠的适宜用量为12％-20％；食用杏鲍菇菌糠配制的全混合日粮颗粒饲料后，波尔山羊羔羊的日增重达到0．122-0．137kg，血液生理生化指标正常。本研究对开发反刍动物饲料新资源、产品以及提高菌糠资源循环利用率和减少环境的污染等方面均具有重要现实意义。

The effects and feasibilities of mixed feed of Boer goat using spent mushroom substrale （SMS） of Pleurotuseryngii were discussed. The resulls of the main heahh and safety indicators show that the Iotal number of myeete, lhe eontenl of aflatoxin and vomitoxinwas decreased by 62.9%, 60.0% and 4-4.9% respectively, and the zearalenone was not detee.ted： At the same time, after the fermentation, the crude protein content increased by 11.98%, and the net, tral detergent fiber and acid detergent fiber decreased by 8.81% and 11.69% respectively. Our studies also indicated that the health indicators and quality of the SMS got better after the fermenlation, whieh canbe used as a high-quality roughage of goat. Meanwhile, lheanalysis results of Boer goat lamb growth performance and blood physiological and biochemical indexesshowed that the appropriate content of 5MS in the mixed feed was 12 20% and the daily gain of the lamh is 0.122-0.137 kg, after feeding the mixed feed, blood physiological and biochemical indieators reached normal levels. This study has important practical significance on developingnew ruminant feed resources, improving the SMS resources cireulation utilization and reducing the environmental pollution.
