Abstract: Objective To investigate the growth and reproductive performance of CMU/1 and CMU/2 ischemia-prone inbred gerbils;And to provide the data support for its’application,conservation and breeding.Methods The generations F20~F22 of 2 gerbil lines were selected and bred in accordance with inbreed Mating rule.The litter interval,the number of birth,the number of weaned pups and the growth curve of the 1~5 litters was analyzed.Results The birth weight of CMU/1 and CMU/2 was 2.5 g to 3.4 g.The litter size ranged from at least 1 to the most 9.The survival rate of weaned litter from 65% to 75%.The shortest litter interval was 14 days,whereas the longest 171 days.The weight gain at 2 to 6 week of age was more rapid.Conclusion There is significant difference in litter size between CMU/1 and CMU/2 ischemia-prone inbred gerbil.Most of them display birth intervals in the 21~70 day.Genotype seems have no effect on the reproductive characteristics of ischemia-prone inbred gerbils.
