微生物添加剂对哺乳仔猪增重效果的研究

EFFECT OF MICROBIAL ADDITIVE IN CHIET ON GAIN OF PIGLETS

本文研究了微生物添加剂Ｃ号菌种和Ｘ菌种在不同营养水平下对哺乳仔猪增重效 果的影响．在基础饲粮每公斤含粗蛋白分别为２０和１８％，消化能分别为３．３和 ３．１兆卡的条件下，试验组同时添加０．１５％微生物添加剂Ｃ菌种和Ｘ菌种．结果 表，ＣＩ组比对照组增重提高２２．２２％，耗料指数下降１％；ＣⅡ组比对照组增重提 高２２．６１％，耗料指数下降５．９％；ＣⅠ和ＣⅡ组分别比对照Ⅰ和Ⅱ组平均头平增加 纯收入９．５２元和９．４１元；Ｃ菌种比Ｘ菌种增重效果显著（Ｐ＜０．０１）．

In the trial the effect of 0.15%, microbial additive bacillus species of type c and type x on the gain of piglets as studied. Diet I had protein (cp) 20% and digestible energy (DE) 3. 3 Mcal . / kg, and Diet Ⅱ cp 18% and DE. the results indicate the CⅠand CⅡ are 22, 22%, 22. 61% more gained and 1%, 5. 9% less consumed; and thene appenrs better probit of 9. 52 Yuan and 9. 41 Yuan per head respeitively. The bacillus species of type c is better than type x (P<0. 01). The weight gain is a critoicle index of effects of microbial additives on piglet performance.
