坑池发酵马铃薯渣饲喂猪的效果试验

Effect of Potato Residue Fermented in Pits on Feeding Pig

采用坑贮池乳酸菌发酵的马铃薯渣喂猪,试验组比对照组每头猪平均日增重提高53.6g,提高11.68％,料重比试验组为3.49:1,比对照组的3.95:1提高13.2％,投入产出比试验组为1:1.44,比对照组的1:1.28提高13.85％,每头平均体重试验组比对照组提高9.8±7.85kg,经t检验,试验组增重显著(P<0.05)。

Potato residues fermented in pits by lacto-bacteria were used to feed pigs. The results showed that the average daily gain of the pig in the experimental group increased 53. 6g than that in the control group, which was 11. 68% ; the feed conversion and the input-output ratio in the experimental group(3.49:1 and 1:1.44) improved by 13.2% and 13.85% respectively than those in the control group (3.95:1 and 1:1.28} ;the average body weight of pig in the experimental group increased 9.8 ±7.85kg than that in the control group. The result of t testing indicated the experimental group had a significant gainf P < 0.05).
