摘要
选用72头28±2日龄断奶杜×长×大三元杂交仔猪,随机分为4个处理,每个处理3个重复,每个重复6头猪(♂3、♀3),自由采食和饮水。结果表明:日粮中添加低聚木糖对断奶仔猪平均日增重(ADG)和B、C组的腹泻率有明显影响(P<0.05);与对照组相比,添加低聚木糖能显著降低仔猪肠道大肠杆菌的浓度(P<0.05)。并能有效促进B组的盲肠,C组的结肠、盲肠和直肠,D组结肠和盲肠中双歧杆菌的增殖(P<0.05)。不同低聚木糖添加量对直肠中乳酸杆菌的增殖效果与对照组相比,差异不显著(P>0.05);仅B组的结肠和C组、D组的盲肠中乳酸杆菌的浓度得到提高(P<0.05);与对照组相比,添加低聚木糖没有显著提高血清猪瘟抗体效价、免疫球蛋白A及免疫球蛋白M含量(P>0.05),但能显著提高血清免疫球蛋白G的含量(P<0.05)。
Seventy-two piglets weaned at age of 28 day （Duroc ×Landrace × Yorkshire） were randomly assigned to four treatments. Results suggested： There were significant improvement on ADG and the incidence of diarrhea （P〈0. 05）;A group level of the diet significantly improved the concentration of Bifldobacterium in colon and rectum （P〈0. 05） ;Different level of XOS in diet and different methods of the addition had no significant improvement on concentration of lactobacilli in colon（P〉0. 05）, but there were no same effect of all treatments on concentration of lactobacilli in caecum and rectum; Compared to control group, XOS had no significant improvement on the concentration of serum SFD antibody, IgA and IgM （P2〉0.05）, but it had significant improvement on concentration of serum IgG（P〈0.05）.
