Breeding method and application of a common female line of meat and skin rabbits

Abstract

The invention provides a breeding method and application thereof for a common female line of meat-skinned rabbits. The breeding method is as follows: mating a white rex male rabbit with a white meat rabbit female to produce the F1 generation, and mating the F1 generation female rabbit with the white meat rabbit The male rabbits were mated to produce the F2 generation, and the Rr heterozygous F2 generation female rabbits were selected by test crossing with the rex rabbits, and the Rr heterozygous F2 generation female rabbits were backcrossed with the white meat rabbits to produce the F3 generation, and the F3 generation was produced by testing with the rex rabbits. Cross-select Rr heterozygous F3 generation male and female rabbits, cross-cross the Rr heterozygous F3 generation male and female rabbits to produce F4 generation, select F4 individuals whose phenotype is Rex rabbit hair type, and carry out closed generation after establishing the basic group Breeding, that is, cultivating the general-purpose female line of the meat-skin dual-purpose rabbit. The general female line of the meat-skin dual-purpose rabbit obtained by breeding has great production and application value in rabbit breeding or rabbit production.

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...

AI Technical Summary

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 with good reproductive performance in the production of rex rabbits, resulting in low reproductive efficiency and high production costs of rex rabbits; The market price of rabbit meat and skins changes, leading to the frequent switching of breeding rabbits and rex rabbits between rabbit breeding enterprises and farmers, which correspondingly generates high replacement costs of breeding rabbits and causes a large loss of operating time
