摘要
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 1 80d。结果表明 ,试验组每头猪平均日增重为 46 0 .6 7g,比对照组的 3 4 3 .56 g增加了 1 1 7.1 1 g,提高 3 4 .0 9% ,差异显著 ( P<0 .0 5)。试验组每增重 1 kg毛猪的饲料成本比对照组降低 0 .59元 ,每头猪多收益 1 0 3 .6 1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 to resolve the lack of local forage resources in the mountain areas in south Ningxia. The average daily gain per head of treatment and control group were 460.67 and 343.56 g/d respectively during 180 days of trial. The average daily gain of treatment group was 117.11 g greater ( P <0.05) than that of control group, which was increased by 34.09%. The feeding cost per kilogram gain of pigs in treatment group was 0.59 RMB Yuan less than control group and could earn 103.61 RMB Yuan per head more than control group. The results indicatcd that the lack of forage could be effectively resolved and the profit be significantly increased, which supplied a sort of new forage resource for development of pigs in the mountain areas of south Ningxia.
