低聚木糖对仔猪生产性能和肠道菌群的影响

Effect of Xylo-oligosaccharide on Growth Performance and Intestinal Tract Microflora of Piglets

研究低聚木糖（XOS）对仔猪生长性能及对断奶仔猪肠道菌群的影响。选用杜×长×大三元杂交仔猪166头,随机分成3组,每组5个重复,于7日龄诱食后饲喂添加XOS和抗生素的饲料,以观察对仔猪生长性能和断奶仔猪肠道菌群的影响。结果表明：饲喂XOS能显著提高哺乳仔猪的生长性能,且在29-40日龄显著高于抗生素组（P〈0.05）;断奶前后XOS组乳酸菌的含量显著高于抗生素组和对照组,大肠杆菌数量差异不显著。

It is researched that effect of Xylo-oligosaccharide（XOS） on Growth performance and Intestinal tract Microflora of Piglets.166 Duroc× Landrace× Lange white swines were randomly divided into 3 groups with 5 replicates.After foraging at 7 days the basic diet of the 3 groups was the same and treatments were as follows ：one with XOS,one with antibiotics,last one without any additive.Growth performance andIntestinal tract Microflora were observed.The results showed that：Growth increase was significant though feeding XOS,and within 29~40 days it was significant higher than antibiotics groups（P0.05）;AP of weaning,the Content of Lactobacillus was significant higher than antibiotics groups and control group,and the content of Escherichia coli was not.
