利用金荞麦替代部分精料饲喂育肥猪的增重效果试验

The Feeding Experiment Was Conducted on Growing-finishing Pigs with Poyigonum Cymosum

试验在生长育肥猪日粮中使用金荞麦,以减少精料的使用量,观察其对猪日增重及经济效益的影响.结果表明：利用金荞麦在育肥前期（30 ～60 kg）减少12％、后期（60 ～ 90 kg）减少16％的精料使用量,对猪的日增重无影响（P＞0.05）,但可节省精料,节约成本,每增重1 kg的饲料成本可降低0.61元,每头猪1d可增加收益0.31元.

To discuss the effect of Poyigonum cymosum for feeding pig, choose 20 crossbred growing Pigs（ Duroc x Landrace ~ Large White） of 35 kg were randomly divided into 2 groups. Total Mixed Ration（TMR） was used as control group, experimental group used Poyigonum cymosumpartial in diet , reducing the use of TMR in the fattening period （30 - 60 kg） reduced by 12%, later period （60 - 90 kg） reduced by 16%. The results were as follows ; used Poyigonum cymosum reduce the use of TMR could not affect the weight gain of pigs（ P 〉 0.05 ）. and can save TMR use, feed cost per weight of Ikg can be reduced by 0.61 yuan,each pig lday can increase income 0.31 yuan
