Abstract: In order to master the relationship between the daily feed intake of Eutamias sibiricus and food variety,the relationship between the daily feed intake of E.sibiricus and food variety under the laboratory feeding conditions were studied.The results showed that the average daily feed intake of E.sibiricus was（15.35＋1.09）g and there was no significant sexual difference of average feed intake.The weight of E.sibiricus showed a positive correlation with the daily feed intake and the correlation equation was y =0.0487x＋90.102.
