Embodiment 1

[0019] Breeding method for obtaining a new breed of white Rex rabbit through half-sib mating:

[0020] Step 1, select 5 white rex rabbits as male parents, and 20 blue meat rabbits as female parents to carry out crossbreeding to obtain the F1 generation hybrid population, and produce 1 / 16 white Lex rabbits according to the total amount of the F1 generation hybrid population;

[0021] Step 2: Select 5 male rabbits and 20 female rabbits with blue-eyed and white Lex hair type characteristics in the F1 generation hybrid population, and carry out half-sib mating to obtain the F2 generation hybrid population, which is produced by the weight of the F2 generation hybrid population 1 / 8 white Lex rabbit;

[0022] Step 3. Select 5 males and females and 20 female rabbits with blue-eyed and white Lex hair type characteristics in the F2 generation hybrid population, and carry out cross-crossing fixation for generations. In the obtained offspring, eliminate other coat colors in each generatio...

Abstract

The invention relates to a method for breeding a white Rex rabbit new variety. The white Rex rabbit new variety with blue-eye characteristic is bred by using a white Rex rabbit as a male parent and using a chinchilla rabbit as a female parent and by methods of hybridization, backcross and the like. The breeding method is short in time and high in speed. The Rex rabbit new variety bred by the method has the advantages of maintenance of body form of the chinchilla rabbit, high growth speed at the early stage, high feed utilization ratio, high lactation capacity, high breeding rate, coarse feeding resistance, high disease resistance and the like. The white Rex rabbit new variety is distinguished from other white Rex rabbit varieties easily because the white Rex rabbit new variety has unique appearance characteristics of white clothing hairs, flat and upright fine hairs, blue eyeballs, penetrating eyes, big and upright ears and white pelt which is a first-class fur clothing raw material in the Rex rabbit industry.

Description

technical field [0001] The invention relates to a method for cultivating Rex rabbits, in particular to a method for cultivating a new breed of white Rex rabbits. Background technique [0002] The rex rabbits raised in my country are mainly imported from the United States, France and the United Kingdom, forming American, French and other rex rabbit strains. There are many types of rex rabbit coat colors. There are 14 types recognized by the American Rex Rabbit Association and 28 types recognized by the United Kingdom. The color types introduced in my country mainly include beaver, chocolate, white, black, reddish-brown, light yellow, Himalayan, blue-gray, blue-purple blue, etc. These color types have become important symbols for commercially identifying different color systems and quality. my country began to introduce rex rabbits from the United States in the 1980s, and white rex rabbits are the most widely promoted in our country. At present, the main problems in the breedi...
