摘要 为研究Levan型低聚果糖对断奶仔猪生长性能和养分消化率的影响,试验选择18日龄体重(5.5±0.15)kg的240头健康杜长大三元杂种断奶仔猪,按体重相近、公母各半的原则,随机分为3个组,对照组饲喂基础饲粮、阿美拉霉素组在对照组饲粮中添加阿美拉霉素165 g/t、Levan组在对照组饲粮中添加Levan型低聚果糖1 000 g/t。每组8个重复,每个重复10头仔猪,试验期28 d。结果表明:1)0~14 d对照组和Levan组的料重比显著高于阿美拉霉素组(P<0.05);2)15~28 d阿美拉霉素组的日增重显著高于对照组(P<0.05),且料重比显著低于对照组和Levan组(P<0.05);3)15~28 d Levan组的料重比显著低于对照组(P<0.05);4)0~28 d阿美拉霉素组和Levan组的料重比显著低于对照组;5)对照组的腹泻频率显著高于阿美拉霉素组和Levan组(P<0.05);6)与对照组相比,Levan组提高第14天和第28天的干物质、氮和总能的消化率(P>0.05)。总之,试验结果表明在本试验条件下,断奶仔猪饲粮中添加1 000 g/t Levan型低聚果糖降低了料重比和腹泻频率,但未达到添加阿美拉霉素的水平。
