| 摘 要： | 在饲料资源十分缺乏的宁南山区,将当地玉米秸秆微贮后喂猪,并对其生长动态进行分析研究,结果表明,试验组猪的快速生长阶段比对照组增长22．3d,且该阶段的平均日增重和最大日增重分别比对照组高37．98g和43．31g;在整个育肥期,试验组猪平均日增生463．89g,比对照组的366．67g增加97．22g,提高26．51％,差异显著（P＜0．05）,利用秸秆微贮饲料不但提高了养猪业的经济效益,而且为当地养猪业的大力发展开辟了新的饲料资源途径。

| Abstract: | Feeding pigs with microbial straw silage would be well suited to solve the lack of local forage resources in the mountain areas of South Ningxia.The growth dy namic changes have been studied.The results showed that the rapid growth stage of treatment group was 22.3 d longer than that of control group,and the average daily gain and the hightest daily gain was 37.98 g and 43.31 g respectively greater than that of control group;The average daily gain per head of treatment and control group were 463.89 g/d and 366.67 g/d respectively during 180 days trial.The average daliy gain of treatment group was 97.22 g greater (P<0.05) than that of control group,which was increased by 26.51%.The results indicated that the lack of forage could be effectively resolved,significantly increased profit,and significantly supplied a sort of new forage resource for development of pigs in the mountain areas of South Ningxia. |
