树的人工哺育

为探索和建立人工哺育树鼠句的可行方法 ,将 5对成年树鼠句配对后饲养在繁殖笼内 ,喂与由标准动物粉状饲料、奶酪、新鲜蔬菜和水果构成的混合食物。新生树鼠句出生后立即从母笼移出至孵育箱 ,每日人工喂与专门配制的牛奶制品。三周后将小树鼠句从孵育箱移出 ,经喂与转换食物约 1 0 d,过度到自食成年食物。结果 7个月内 5对成年树鼠句在共产1 1窝 3 1只仔树鼠句。在 2 7只出生后人工喂养的仔树鼠句中 ,2 5只健康存活至进入动物实验 ,人工喂养成活率为 92 .6%。树鼠句平均产仔间隔 5 2± 8.9d;平均窝产仔数 2 .8± 0 .4只。人工哺育树鼠句的成功为提供树鼠句应用于医学实验研究 ,尤其是与肝癌、肝炎有关的研究 ,开拓了广阔的前景。

Hand Rearing of Tree Shrews (Tupaia belangeri chinensis)

To explore and develop a practical way for hand rearing tree shrews, which is one kind of very useful animal in medical research. 5 pairs of adult tree shrews were housed in breeding cages, fed on the food mixed with purified standard diet, cheese,fruits and vegetables. Newborn tree shrews were moved out from their mothers' cages soon after birth and kept in an incubator for about 3 weeks. The infant tree shrews were fed on a milk formula for the first 3 weeks, then they were moved out from the incubator and fed on a transitional diet for 10 days when they got ready for adult food. There were 31 pups in 11 litters were born in 7 months by 5 pairs of adults, in which 27 pups were hand-reared from birth and 25 of them survived to 7 weeks of age when they were used in an experiment. The average period between the day of pairing and the day of parturition was 52 ± 8. 9 days. The average litter size was 2. 8±0. 4. The results showed that the survival rate of hand-rearing the newborns in this experiment was 92.6%, which is higher than those reported in related publications. The success in hand rearing tree shrews would make it possible to meet the increasing demand of tree shrew in medical research, especially in the field related to liver cancer and hepatitis.
