在饲料资源非常紧缺的宁南山区，将玉米秸秆制成微贮饲料后喂猪，试期180d。结果表明，试验组每头猪平均日增重为460.67g，比对照组的343.56g增加了117.11g，提高34.09%，差异显著(P<0.05)。试验组每增重1kg毛猪的饲料成本比对照组降低0.59元，每头猪多收益103.61元，效益十分显著。这不但有效解决了该地区饲料紧缺这一严重问题，而且也大大提高了养猪业的经济效益，为宁南山区养猪业的大力发展开辟了新的饲料资源。%Feeding pigs with microbial straw silage would be well suited toresolve the lack of local forage resources in the mountain areas in south Ningxia.
