香茹菌糠饲喂生长猪的效果研究

STUDY O N E FFECT OF RSSL MIXED FEED ON GROWIN G PIGS

为了评价香菇木屑菌糠饲喂生长猪的效果，用２０头生长猪随机分成４组进行了６４天的饲养试验，研究饲粮中含０～２０％香菇菌糠对生长猪增重速度和饲料成本的影响。试验结果表明：与对照组相比，饲粮中含１０％～２０％的菌糠，生长猪的增重速度无显著差异；饲粮中添加适量菌糠，可降低饲料成本。根据试验结果可以认为，在生长猪饲粮中添加１５％的香菇菌糠是适宜的。

Twenty growing pigs were arbitrarily divided into 4 groups,whose feed in -cluded 0～20%RSSL(the refuse substrate of sawdust medium from Lentinus edodes pro-duction)respectively for 64 days in the study,The effect of RSSL was estimated by averagedayly gain and feed utilized ratio.The results showed that:1)There was on significant diversity for average dayly gainbetween all groups;2)Feed cost was lowered by mixing appropriate RSSL in the feed.Theresults also indicated that it would be suitable to mix the feed with 15%RSSL for growingpigs.
