The data on the breeding and growth of the animal wereobtained and described as following in the present paper. 1. The mean life span was26±14month old for males and 27±13 month old for females.2. The mean bodyweight of the Mongolian gerbils at 16 weeks of age was 72±5.6g for males and 62±7.3gfor females.3. The mean litter size at birth was 4.8±1.7 head. (range; 1-9) 4.More newborn pups were born in the warm seasons (March-October) than the coldseasons (November-February) . 5.
