Problems solved by technology

Purification of coat color by conventional breeding methods is very difficult
[0004] Since the introduction of Belgian rabbits to my country, affected by the production conditions and natural environment in my country, coupled with high genetic heterozygosity and lack of systematic breeding, the Belgian rabbits have more mixed coat colors, slower growth, smaller hides, and lower production performance. Adapt to modern large-scale production of rabbits

Embodiment 1

[0068] A method for breeding a new breed of large-scale Belgian fur-colored meat and skin rabbits. The breeding process is as follows: figure 1 shown, including the following steps:

[0069] (1) 30 Flanders male rabbits were mated with 150 Kangda meat rabbit matching line V-line meat rabbit female rabbits to obtain the F1 generation;

[0070] (2) Select the F1 generation of male rabbits with Belgian coat color and Kangda meat rabbit matching line V-series meat rabbit female rabbits to backcross to obtain the F2 generation;

[0071] (3) From the F2 generation, select Belgian-colored male rabbits and the V-series meat rabbit female rabbits of the Kangda meat rabbit line to backcross again to obtain the F3 generation;

[0072] (4) Select the Belgian-coated male rabbit and the Belgian-coated female rabbit in the F3 generation for cross propagation to obtain the F4 generation;

[0073] (5) Select Belgian-coated male rabbits and Belgian-coated female rabbits in the F4 generation, ...

Embodiment 2

[0084] The only difference between this example and Example 1 is that the "Kangda Meat Rabbit Matching Line V Series Meat Rabbit Female Rabbit" is replaced by "Ipulu Meat Rabbit Matching Line A Series Meat Rabbit Female Rabbit", and the closed passage selection is 3 generation, and other operations are the same as in Example 1.

experiment example

[0086] 1. Determination of production performance

[0087] Select 80 litters of the new breed of large-scale Belgian fur-colored and meat-skinned rabbits obtained in Example 1, and name them as the example group, and select 80 litters of Flanders rabbits, and name them as the control group. Under uniform feeding and management conditions, their coat color, growth and development were measured respectively. , reproductive performance and slaughter performance, see Table 2 for specific data.

[0088] Table 2-The results of pure breeding production performance test

[0089]

[0090] As can be seen from the data in Table 2, the color purity, growth rate and material-to-weight ratio of the large-scale Belgian fur-colored skin obtained in Example 1 of the present invention are significantly better than those of the control group. The breeding method of dual-purpose rabbit new strain is mature and applicable.

Abstract

The invention provides a new-breed large-sized Belgian coat-color rabbit culture method for fur and meat dual use. The culture method comprises the steps that firstly, a male Belgian coat-color rabbitand a female white meat rabbit are subjected to mating to obtain an F1 generation; the male Belgian coat-color rabbit and the female white meat rabbit in the F1 generation are selected for backcrossto obtain an F2 generation; the male Belgian coat-color rabbit and the female white meat rabbit in the F2 generation are selected for backcross again to obtain an F3 generation; the Belgian coat-colorrabbits in the F3 generation are selected for crossing to obtain an F4 generation; the male and female Belgian coat-color rabbits in the F4 generation are selected for gene identification, and male and female homozygotic-type Belgian coat-color rabbits are selected for building a basic group; the basic group is subjected to closed continuous progeny breeding for 3-4 generations, and a new breed of the large-sized Belgian coat-color rabbits with meat and fur dual use, which have identical body shapes and appearances is cultured. By means of the new breed obtained through the culture method, during pure reproduction and hybridization production, it can be guaranteed that the hair colors of the goods-generation rabbits are identical, and the method has high production performance and uniformity and is suitable for a complete set of modernized production of meat rabbits.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and in particular relates to a method for cultivating a new breed of large-scale Belgian fur-colored meat-skinned rabbit. Background technique [0002] The Belgian rabbit is domesticated and bred from the European wild rabbit, also known as the Flanders rabbit in Europe. The fur color of Belgian rabbit belongs to the wild type. The coat is dark red with yellowish brown or reddish brown. The ends of the whole hair are deep and the middle is lighter. The texture is tough and clings to the body surface. Belgian rabbit fur is beautiful in color, with natural luster, flexible and elastic skin, and is favored by the fur market. In addition, the consumption of fresh and live rabbits has a large demand for Belgian colored meat rabbits, and the market price is relatively high. [0003] The genetic background of Belgian rabbit coat color is relatively complex, carrying multiple coat color gene...
