Tree shrew large-scale mating breeding method

Abstract

The invention provides a tree shrew large-scale mating breeding method, which comprises: 1) breeding breeding male and female tree shrews in a ratio of 1:5; 2) breeding the female and male tree shrews in single cages separately and numbering the tree shrews with the numbers of the cages for production recording and management; 3) mating: allowing a group of tree shrews to mate every 10 to 15 days, wherein each group comprises 50 female tree shrews, the female and male tree shrews are bred in one cage according to a ratio of 1:1 for 3 to 5 days, and after the mating in one cage, examination for finding embryos is performed on the 10th or 12th day from the mating day on; 4) managing mating male tree shrews: mating spare male tree shrews which are over five moths old three times each month, wherein after each time of mating, the male tree shrews may have a rest for 7 to 12 days; and 5) managing mating female tree shrews: after the mating and embryos finding of spare female tree shrews which are over four moths old, allowing the non-pregnant tree shrews, the tree shrews who do not mate because of body weakness and restore health and the tree shrews weaned and have rested for one week to mate again, wherein the non-pregnant female tree shrews are allowed to mate and be impregnated twice a month. The method can improve the utilization of male tree shrews, reduce production cost and realize batch production.

Description

technical field [0001] The invention relates to a breeding method for large-scale mating of tree shrews under laboratory conditions. Background technique [0002] Research data on tree shrew behavior shows that: under normal circumstances, tree shrews live alone, but the territory of a male tree shrew always overlaps with the territory of one or several female tree shrews, which reveals that tree shrews belong to the same group under natural conditions. One-female or one-male multi-female reproduction. According to literature reports, under laboratory conditions, tree shrews usually use 1:1 or 1:2 long-term cage mating. The separation of the sexes is carried out only after the female tree shrews are confirmed to be pregnant. Long-term cohabitation, on the one hand, leads to a decline in the male tree shrew's libido and physical fitness, and poor sperm quality. On the other hand, it is impossible to determine the exact time of conception of female tree shrews. Uncertain fe...

Problems solved by technology

[0003] Because the long-term cohabitation and mating method of male and female tree shrews is not suitable for tree shrew reproduction under laboratory conditions, artificial breeding of tree shrews has not achieved good results for many years, and mass production of tree shrews cannot be realized
