CMU/1和CMU/2长爪沙鼠繁殖性能与生长发育观测
Preliminary Study on Growth and Reproductive Performance of Inbred Mongolian Gerbil Strains CMU/1 and CMU/2
摘要
Abstract
Objective To investigate the growth and reproductive performance of CMU/1 and CMU/2ischemia-prone inbred gerbils; And to provide the data support for its' application, conservation and breeding. Methods The generations F20F22 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 15 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 to6 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 2170 day. Genotype seems have no effect on the reproductive characteristics of ischemia-prone inbred gerbils.关键词
