摘　　要：试验将发酵白术作为添加剂以0．1％，0．2％，0．3％三个梯度添加于基础日粮中，与添加O．2％未发酵白术组，添加抗生素组以及基础日粮组对照，研究其对断奶仔猪生长性能影响。结果表明，①生长性能：与对照组相比，日粮中添加发酵白术饲料添加剂能增强断奶仔猪食欲，提高断奶仔猪采食量和日增重，降低断奶仔猪腹泻率。与添加抗生素组相比，添加发酵白术组在采食量、日增重方面优于抗生素组。与添加未发酵白术组相比，添加发酵白术组断奶仔猪生长性能和腹泻率要优于未发酵白术组。②免疫功能：在试验前期（1．14d），0．2％发酵白术组能够显著提高断奶仔猪血清中IgA、IgG、IgM及总蛋白（TP）和白蛋白（ALB）含量（P〈0．05），谷丙转氨酶（ALT）和谷草转氨酶（AST）含量有下降趋势，但差异不显著（P〉0．05）。在试验全期（1-28d），0．2％发酵白术组IgA、IgG和IgM含量显著（P〈0．05）高于对照组和未发酵组，0．2％和0．3％发酵白术可以显著提高血清中总蛋白（TP）和白蛋白（ALB）含量，0．2％发酵白术组可显著降低血清中尿素氮（BUN）72．ALT含量，0．3％发酵白术组AST含量显著降低。综合试验各项指标，断奶仔猪饲粮中发酵白术最适宜添加量为0．2％。This experimenthas reseached that whether the fermented Atractylocles, added to basal diet with 0.1%, 0.2% and 0.3%, has influence to the growth of the weaned piglets, though compared with 0.20% unfermented Atractylocles group, antibiotics group and basal diet groupwith the single factor design. The results showed that： （1） The growth performance： compared with the control group, the basal diet with fermented Atractylodes could enhanc the appetite of weaned piglets, and improve the feed intake, daily gain and reduce diarrhea rates, compared with the antibiotics group, the fermented Atractylodes was better than it in feed intake, daily gain respect, compared with theunfermented Atractylodes group, the fermented Atractylodes group was better on the growth and diarrhea rate. （2） The immune function： At the early stage of the experiment （1-14 d）, 0.2% fermented Atractylodes group can significantly improve contents of IgA, IgG, IgM andthe total protein in serum （TP） and albumin （ALB） （P〈0.05） in the weaned piglets serum, alanine aminotransferase （ALT） and aspertate aminotransferase （AST） levels have a downward trend, but no significant difference （P〉0.05）; In the whole test period （1-28 d）, the content of IgA, IgG and IgM among 0.2% fermented Atractylodes- group is significantly （P〈0.05） higher than that of the comparing group and unfermented group.added 0.2% and 0.3% fermented atractylodes can significantly improve the total protein in serum （TP） and albumin （ALB） content,and added 0.2% fermented Atractylodes can significantly reduce the content of serum urea nitrogen （BUN） and alanine aminotransferase （ALT）. and 0.3% fermented Atractylodes group AST content is significantly reduced. Integrated the test indicators, the optimumadding amount weaned piglets fodder in the fermentation of Atractylodes 0.2% .It is concluded that 0.2% fermented Atractylodes in diets for piglets is the best.
