不同笼具饲养树鼩繁殖效果研究

Breeding Effects of Tupaia belangeri chinensis Raise with Different Cages

[目的]探讨不同笼具对树鼩繁殖效果的影响。[方法]在室内笼养条件下,将120只健康成年树鼩按1∶2雄雌比例,随机分成4组,配对饲养于A、B、C、D 4种笼具,进行为期一年的繁殖效果观察。[结果]笼具A,受孕46次,产仔136只,死产2窝,流产1窝,未出现外伤、死亡。笼具B,受孕42次,产仔126只,死产2窝,流产2窝,未出现外伤、死亡。笼具C,受孕21次,产仔68只,死产1窝,流产1窝,出现1外伤,未出现死亡。笼具D,受孕7次,产仔16只,死产1窝,流产1窝,出现2只外伤。[结论]笼具A、B适合作为繁殖笼;笼具C、D可作为一般饲养笼。

[ Objective] Breeding effects that the tree shrews （ Tupaia belangeri chinensis） breed with different cages are explored in the pa- per. [ Method] Under the situation of the laboratory, there were four cages marked A, B, C and D. The aduh 120 healthy tree shrews were kept couples feeding by comparisons of 1：2 female and male, and raised with these cages. [ Result] After a year, the tree shrews which raised with cage A conceived 46 times in total, giving birth to 136 pups, having misbirth 2 nests, having stillbirth 1 nest. There was no unexpected death or injured. The tree shrews which raised with cage B conceived 42 times in total, giving birth to 126 pups, having misbirth 2 nests, hav- ing stillbirth 2 nests. The cage was B exactly the same as the cage A. There was no unexpected death or injured. The tree shrews which raised with cage C conceived 2l times in total, giving birth to 68 pups, having misbirth 1 nests, having stillbirth lnests. One of them was injuried. The tree shrews which raised with cage D conceived 7 times in total, giving birth to 16 pups, having misbirth 1 nests, having stillbirth 1 nests. The two tree shrews raised with cage D was injuried. [ Conclusion] Cage A and B are able to breeding tree shrews, Cage C and D can be used as a general feeding cage.
