摘    要:选取21日龄的杜×长×大三元杂交断奶仔猪150头,随机分成3组,每组设2个重复,每个重复25头。A组(对照组)饲喂基础日粮;B组和C组分别在基础日粮中添加0.05%和0.10%的酵母培养物。试验结果表明:①C组的日增重显著高于A组(P<0.05),B、C组之间差异不显著(P>0.05);②C组的采食量显著高于A组(P<0.05);③随着酵母培养物添加量的增加,料重比有下降的趋势;④C组的腹泻头数比对照组有明显减少,死亡淘汰数也有明显降低。

关 键 词:酵母培养物  断奶仔猪  生长性能  日增重

Abstract:This study selected the 150 Duroc×Landrace×Yorkshire three miscellaneous pos tweaning piglets while 21 day old, randomly divided into three groups, each group has two repeat, each of the repeat with 25 piglets. Group A (the control group), using the basic diet; group B and group C were in the basis of the diet added 0.05% and 0.10% yeast cultures. The results showed that: ①the daily gain of group C was significantly higher than that of group A (P<0.05), differences between the groups B and C were not significant (P>0.05); ②the intake of group C was significantly higher than group A (P<0.05); ③with the addition of yeast cultures increased, feed weight ratio has downward trend; ④the number of diarrhea piglets in group C was significantly reduced than group A,and the number of deaths out decreased significantly as well.
Keywords:yeast cultures  post-weaning  growth performance  daily gain
