Abstract: Taking the carcass weight as the index for establishing fatness degree index (K′), this paper analyzed the effects of striped hairy-footed hamster (Phodopus sungorus) age and sex, grazing intensity, and habitat vegetation status on the K′ of the P. sungorus in Inner Mongolia of China. No significant differences were observed in the K′ between the males and females. The age group I had the smallest K′, being significantly different from age groups II, III, and IV. The K′ was higher in immaturity group than in maturity group. The K′ was not significantly different under different grazing intensities. The K′ varied significantly with the plots of different vegetation coverage, being the smallest in the plots of a vegetation coverage >0.61. There was no obvious correlation between the P. sungorusK′ and population size, suggesting that the K′ couldn’t be used as an indicator for the P. sungorus population dynamics.
