Problems solved by technology

[0005] However, in terms of bamboo rat breeding, since the heritability of weight traits and the weight ratio between sexes are still unclear, it is still difficult to establish the terminal male line of bamboo rats, relying on the terminal male line of bamboo rats to control the weight of commercial bamboo rats to meet the requirements of customers in different regions , if the status quo cannot be changed for a long time, customers may be lost, the market share will decrease, the risk of bamboo rat breeding will increase, and the profit of breeding will be reduced

Embodiment 1

[0042] S1. Select N male bamboo rats and 3N female bamboo rats, and establish N families according to each family including 1 male bamboo rat and 3 female bamboo rats, wherein, N≥50;

[0043] S2. Select and breed the established N families for one generation, count the reproductive performance I of each family, and sort the families according to the size of reproductive performance I, and select N from the families whose reproductive performance I ranks in the top 50% Male bamboo rats and 3N female bamboo rats establish N families again;

[0044] S3, repeating step S2, until the adult offspring body weight heritability estimation value of the bamboo rat of the same generation, the evenness heritability estimation value reach the first threshold value, the second threshold value respectively, then obtain the Chinese bamboo rat terminal male line;

[0045] Among them, there is no blood relationship between the bamboo rats in each family.

Embodiment 2

[0047]S1. Select N male bamboo rats and 3N female bamboo rats, and establish N families according to each family including 1 male bamboo rat and 3 female bamboo rats, wherein, N≥50;

[0048] S2. Select and breed the established N families for one generation, count the weight performance I of each family, and sort the families according to the size of the weight performance I, and select N male bamboo rats and With 3N female bamboo rats, N families were established again;

[0049] S3, repeating step S2, until the adult offspring body weight heritability estimation value of the bamboo rat of the same generation, the evenness heritability estimation value reach the first threshold value, the second threshold value respectively, then obtain the Chinese bamboo rat terminal male line;

[0050] Among them, there is no blood relationship between the bamboo rats in each family;

[0051] Before step S1, it also includes determining the optimal body weight ratio of female bamboo rats an...

Embodiment 3

[0056] S1, select 50 male bamboo rats and 150 female bamboo rats, and set up 50 families according to each family including 1 male bamboo rat and 3 female bamboo rats;

[0057] S2. Select and breed the established 50 families for one generation, count the weight performance I of each family, and sort the families according to the size of the weight performance I, and select 50 male bamboo rats and 150 female bamboo rats, and 50 families were established again;

[0058] S3, repeating step S2, until the adult offspring body weight heritability estimation value of the bamboo rat of the same generation, the evenness heritability estimation value reach the first threshold value, the second threshold value respectively, then obtain the Chinese bamboo rat terminal male line;

[0059] Among them, there is no blood relationship between the bamboo rats in each family;

[0060] Before step S1, it also includes determining the optimal body weight ratio of female bamboo rats and male bamb...

Abstract

The invention discloses a method for culture of a Chinese bamboo rat terminal paternal line. The method comprises a step S1 of selecting N male bamboo rats and 3N female bamboo rats, and establishingN families according to the standard that each family includes 1 male bamboo rat and 3 female bamboo rats; a step S2 of performing breeding of one generation on the N established families, calculatingweight performance I of each family, sorting each family according to the weight performance I, selecting N male bamboo rats and 3N female bamboo rats in the family with the weight performance I reaching the standard, and establishing N families again; a step S3 of repeating the step S2, until weight heritability estimated values of the same generation of bamboo rat adult offspring and estimatedvalues of evenness heritability reach a first threshold and a second threshold respectively, and obtaining the Chinese bamboo rat terminal paternal line. The method meets the requirements of customersin different regions for weights and uniformity of slaughter bamboo rats, the market share is increased, and the bamboo rat culture benefit is improved.

Description

technical field [0001] The invention relates to the field of bamboo rat breeding. More specifically, the present invention relates to a method for cultivating the terminal male line of the Chinese bamboo rat. Background technique [0002] The bamboo rat has a large body and a lot of meat, delicious taste, rich nutrition, thick and soft fur, and has high economic value and medicinal value. It has been cultivated on a large scale in China and has become one of the breeding industries with economic benefits. [0003] When the animals are slaughtered, customers will have requirements on the weight and uniformity of the slaughtered animals. That is, the average weight and weight range of slaughtered animals must meet the customer's requirements. Even if the average weight meets the customer's requirements, the weight difference between individual animals for slaughter should not be too large. [0004] Moreover, customers in different regions have different requirements for the...
