[Objective] The research aimed to discuss the effects of feeding attractant added in supplemental feed on intake,performance and digestibility of nutrient substance in lambs.[Method] In the single factor random grouping test,13 day-old healthy,weight similar male Xinong Saanen lambs were selected,were randomly divided into 4 treatments of A,B,C and D with 6 duplications per treatment.Group A was control group,fed with basic supplemental feed.Group B was fed with basic supplemental feed added 3% cane sugar.Group C was fed with basic supplemental added 3% cane sugar and milk tasted flavor 1.0 g/kg.Group D was fed with basic supplemental added 3% cane sugar and strawberry tasted flavor 1.0 g/kg.[Result] The results showed that the intake and average daily gain of B,C and D groups were higher than group A 4.82(3.48%),15.13(10.94%),18.06 g(13.05%)and 21.95(17.47%),49.77(39.61%),54.97 g(43.75%).The dry matter,crude protein, total energy digestibility of B,C and D groups were higher than group A 1.89%, 9.09%,10.20% and 4.65%,6.35%,6.74% and 0.87%,7.67%,6.69%.[Conclusion] Group D was more effective to improved intake,average daily gain,feed conversion rate and the apparent digestibility of nutrient substance of diet,which was fed with basic supplemental added 3% cane sugar and strawberry tasted flavor 1.0 g/kg.
