Problems solved by technology

However, due to the poor quality and low utilization value of meat rabbit skins, slow growth and reproduction of rex rabbits, and low meat efficiency, these two types of specialized species often cannot take care of both meat and skin, and they are completely separated in breeding production.
There have been two outstanding problems in the production of domestic rabbits for a long time: one is the lack of specialized maternal breeds w

Embodiment 1

[0034] A kind of breeding method of meat-skinned rabbit general maternity line, the breeding process is as follows figure 1 shown, including the following steps:

[0035] (1) Select 50 male white rex rabbits and 150 specialized female rabbits of white meat rabbits to mate and produce the F1 generation;

[0036] (2) Select F1 generation female rabbits and white meat rabbits to breed male rabbits to produce F2 generation. Select F2 generation female rabbits and Rex rabbit male rabbits for test crossing. If the coat of offspring includes both normal type and Rex rabbit hair type, Then the F2 generation female rabbit is Rr heterozygous type;

[0037] (3) Backcross the Rr heterozygous F2 generation female rabbit with the white meat rabbit specialized female line male rabbit to produce the F3 generation, test cross the F3 generation with the Rex rabbit, if the coat of the produced offspring includes normal type and Rex rabbit hair type, then the F3 generation genotype is the Rr he...

Embodiment 2

[0040] The difference between this example and Example 1 is that in step (4), the Rr heterozygous F3 generation is carried out orthogonally and inversely crossed with the mother line of Rex rabbit, and 4 generations are selected by locked-up subculture, and other operations are all the same as those in Example 1. 1 is the same.

Embodiment 3

[0042]The difference between the present embodiment and the embodiment 1 is that the closed subculture selection in the step (4) is 5 generations of selection, and other operations are the same as the embodiment 1.

Abstract

The invention provides a cultivating method of general-purpose maternal sides of meat and skin dual-purpose rabbits and an application of the cultivating method. The cultivating method comprises the steps of selecting white male rex rabbits and white female meat rabbits, performing mating to produce F1-generation rabbits, enabling F1-generation female rabbits and the white male meat rabbits to bemated to produce F2-generation rabbits, through test cross with rex rabbits, selecting and remaining Rr heterozygosis type F2-generation female rabbits, performing backcross on the Rr heterozygosis type F2-generation female rabbits and white male meat rabbits to produce F3-generation rabbits, through test cross with the rex rabbits, selecting and remaining Rr heterozygosis type F3-generation maleand female rabbits, enabling the Rr heterozygosis type F3-generation male and female rabbits to be subject to athwart cross to produce F4-generation rabbits, selecting F4 representative types as individuals of rex rabbit hair types, establishing underlying groups, and then performing locking subculture so as to complete cultivating of the general-purpose maternal sides of the meat and skin dual-purpose rabbits. The general-purpose maternal sides of the meat and skin dual-purpose rabbits, obtained through breeding, have great production and application value in breeding or producing of domesticrabbits.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and in particular relates to a breeding method for a common female line of a rabbit with both meat and skin and its application in rabbit breeding or rabbit production. Background technique [0002] People raise rabbits mainly for the production of rabbit meat and rabbit skin, and use mutations in coat genes to breed specialized meat rabbits and rex rabbits respectively. In fact, the breeds of meat rabbit and rex rabbit are dual-purpose rabbits with different emphasis on meat and leather production. However, due to the poor quality and low utilization value of the skins of meat rabbits, the slow growth and reproduction of rex rabbits, and the low efficiency of meat use, these two types of specialized species often cannot take care of both meat and skin, and they are completely separated in breeding production. There have been two outstanding problems in the production of domestic rabb...
