Problems solved by technology

However, unlike other domesticated livestock and poultry, the Chinese bamboo rat has established a relatively complete breeding system. Humans have not domesticated the Chinese bamboo rat for a long time, especially the breeding technology of the Chinese bamboo rat is not perfect enough. The selection of (strains) still stays at the primary phenotype selection, such as slaughter weight, observation of daily activity, etc.
However, there is a high genetic negative correlation between the weight of bamboo rats and their reproductive performance. If one-sided pursuit of slaughter weight, the reproductive performance of bamboo rats will be reduced. If one-sided pursuit of reproductive performance of bamboo rats, it will also lead to low weight of bamboo rats

Embodiment 1

[0036]A kind of supporting method of Chinese bamboo rat parent generation breed mouse, comprises the following steps:

[0037] S1. Determine the standard weight range of female bamboo rats as X 1 -X 2 (The selected female and male bamboo rats are all purebred Chinese bamboo rats):

[0038] With 1.225kg as the minimum weight, every 50g increase in body weight is a weight level to 1.525kg as the highest weight, and a total of weight level Ⅰ (1.225kg-1.275kg), weight level Ⅱ (1.275kg-1.325kg), and weight level Ⅲ were obtained respectively. (1.325kg-1.375kg), weight level IV (1.375kg-1.425kg), weight level V (1.425kg-1.475kg), weight level VI (1.475kg-1.525kg) six weight levels, within each weight level Including the minimum body weight within the range of this weight level, excluding the highest body weight within the range of this weight level, select 20 female bamboo rats for each weight level, and breed them with male bamboo rats with a body weight within the range of 1.49-1...

Embodiment 2

[0051] A kind of supporting method of Chinese bamboo rat parent generation breed mouse, comprises the following steps:

[0052] S1. Determine the standard weight range of female bamboo rats as X 1 -X 2 , and determine the standard weight range Y of male bamboo rats 1 -Y 2 , where X 1 -X 2 and Y 1 -Y 2 The determination of is subject to the data determined in Example 1, that is, X 1 -X 2 1.375kg-1.425kg, Y 1 -Y 2 1.65kg-1.71kg;

[0053] S2, select female bamboo rats and male bamboo rats within the standard body weight range in the first male line and select female bamboo rats and male bamboo rats within the standard body weight range in the female line to carry out closed breeding respectively, specifically:

[0054] Step 1. Select 60 male bamboo rats with a body weight of 1.65kg-1.71kg and 180 female bamboo rats with a body weight of 1.375kg-1.425kg from the first male line, and include 1 male bamboo rat for each family 60 families were established with 3 female ba...

Abstract

A supporting method of a parental breeding species of Rnizomys sinensis comprises the steps of S1, dividing individuals of Rnizomys sinensis into a first paternal line and a maternal line, and determining standard weight ranges of female and male individuals in the first paternal line and the maternal line; S2, selecting, from the first paternal line, the female and male individuals having the standard weight ranges, and, from the maternal line, the female and male individuals having the standard weight ranges for the purpose of latching breeding; S3, after the latching breeding, using the male individuals from the first paternal line as progenitor male parents and the female individuals from the male line as progenitor female parents, subjecting the progenitor male parents and the progenitor female parents to natural mating to obtain the parental breeding species. The parental breeding species obtained herein features high litter size and high rate of live litter, and provides increased economic benefit in cultivation of Rnizomys sinensis.

Description

technical field [0001] The invention relates to the technical field of bamboo rat breeding, in particular to a matching method for the parent generation of the Chinese bamboo rat. Background technique [0002] The Chinese bamboo rat is referred to as the bamboo rat, also known as the bamboo root rat, the bamboo root pig, the bamboo civet, the mang civet, the bamboo weasel, the moss rat, and the scorpion rat. It belongs to the vertebrate subphylum, mammalia, rodents, and bamboo rat family. The Chinese bamboo rat has a thick, cylindrical body, a blunt head and a large snout. Because of its delicious taste, rich nutrition, thick and soft fur, and high economic value and medicinal value, Chinese bamboo rat has become one of the breeding industries with economic benefits. However, unlike other domesticated livestock and poultry, the Chinese bamboo rat has established a relatively complete breeding system. Humans have not domesticated the Chinese bamboo rat for a long time, espec...
