摘　　要：为研究两种不同风味诱食剂对羔羊采食行为和生产性能的影响,本试验选用15日龄小尾寒羊与杜泊绵羊杂交一代羔羊24只,随机分为3组,每组8只。Ⅰ组为对照组,饲喂基础补饲料;Ⅱ组在基础补饲料中添加0.13%青草香味诱食剂;Ⅲ组在基础补饲料中添加0.13%乳香味诱食剂。试验结果表明,Ⅱ组羔羊的采食时间和每次采食持续时间最长,显著高于Ⅰ组(P<0.05)。青草味诱食剂可提高羔羊的生产性能,随着羔羊日龄的增长,Ⅱ组羔羊采食量显著高于Ⅰ、Ⅲ组(P<0.05);而料肉比显著低于Ⅰ、Ⅲ组(P<0.05)。综合考虑,基础补饲料+0.13%青草香味诱食剂对提高羔羊采食量、平均日增重及饲料转化率效果较好。This experiment was conducted to study the effects of two different flavor feeding attractant added in sup- plemental feed on feed intake behavior and production performance in lambs.In the test,24 15-day-old small-tailed Han sheep and Dorper sheep hybrid generation lamb were selected and randomly divided into 3 treatments of 8 each.Group Ⅰ was control group.Group Ⅱ was fed basal supplemental feed added 0.13% grass scent attraetant.Group Ⅲ was fed with basal supplemental feed added 0.13% frankincense scent attractant.The results showed that：the lamb feeding time and feeding duration of the group Ⅱ were the longest and significantly higher than those of group Ⅰ （P 〈 0.05）.Feeding at- tractant could improve production performance of the lamb.With the growth of age,feed intake of group Ⅱ was significant- ly higher than that of group I and group m 〈P 〈 0.05）,and the feed conversion ratio of group Ⅱ was significantly lower than that of group I and m （P 〈 0.05）.Comprehensive consider basal supplemental feed added 0.13% grass scent attrac- tant could improve feed intake, average daily gain and feed conversion rate of the lamb.
