Embodiment 1

[0066] A method for cultivating new strains of black meat rabbits with higher production performance. The breeding process is as follows: figure 1 shown, including the following steps:

[0067] (1) Mating 30 Laiwu Black Rabbit male rabbits with 150 Kangda Meat Rabbit V-line female rabbits to obtain the F1 generation;

[0068] (2) Select the black male rabbit in the F1 generation and backcross the V-series female rabbit of the Kangda meat rabbit matching line to obtain the F2 generation;

[0069] (3) Select the black male rabbits in the F2 generation and the V-series female rabbits of Kangda meat rabbits to backcross again to obtain the F3 generation;

[0070] (4) Select the black male rabbit and the black female rabbit in the F3 generation to carry out cross propagation, and obtain the F4 generation;

[0071] (5) Select the black male rabbit and the black female rabbit in the F4 generation, extract their genomic DNA, use the first primer set and the second primer set to ampl...

Embodiment 2

[0081] The difference between this example and Example 1 is that in step (1), the male black rabbit of southwestern Fujian is mated with the female rabbit of the A-line of the Iplu meat rabbit matching line to obtain the F1 generation, and in step (6), the closed offspring is obtained. Breeding for 3 generations, other operations are as described in Example 1.

experiment example

[0083] 1. Determination of production performance

[0084] Choose 80 litters of the black meat rabbit new strain gained in Example 1, named as the embodiment group, choose 80 litters of Laiwu black rabbits, named as the control group, and under unified feeding and management conditions, measure its coat color, growth and development, reproductive performance and Slaughter performance, the specific data are shown in Table 2.

[0085] Table 2 - Production performance measurement results

[0086]

[0087] As can be seen from the data in Table 2, the higher production performance black meat rabbit coat color purity, growth rate, feed-to-weight ratio, slaughter rate and reproductive performance of the embodiment of the present invention 1 gained are significantly better than the comparative example group, and it can be drawn that this The breeding method of the new strain of black meat rabbit with higher production performance described in the invention is mature and applicable...

Abstract

The invention provides a high-production-performance black meat rabbit new strain breeding method. The breeding method comprises the steps that firstly, local male black rabbits are mated with femalewhite meat rabbits to obtain an F1 generation; the black male rabbits in the F1 generation are selected for backcrossing with the female white meat rabbits to obtain an F2 generation; the black male rabbits in the F2 generation are selected for backcrossing with the female white meat rabbits again to obtain an F3 generation; the black rabbits in the F3 generation are selected for crossing to generate an F4 generation; black male and female rabbits in the F4 generation are selected for gene identification, and homozygotic black male and female rabbits are selected to form a basic group; the basic group is subjected to atresia subculture to breed 3-4 generations, and a high-production-performance black meat rabbit new strain consistent in body shape and appearance can be bred. According to the black meat rabbit new strain bred through the breeding method, in the pure breeding and hybrid production process, it can be ensured that the hair colors of commercial generation rabbits are consistent. Meanwhile, the production performance and uniformity are relatively high, and the method is suitable for modern meat rabbit matching production.

Description

technical field [0001] The invention belongs to the technical field of livestock breeding, and in particular relates to a method for cultivating new strains of black meat rabbits with higher production performance. Background technique [0002] Black rabbit refers to the rabbit whose coat color and eyeball color are black. Among all kinds of rabbits such as meat rabbits, rex rabbits, long-haired rabbits, and ornamental rabbits, black is one of the most common rabbit coat colors. Black not only serves as an easily identifiable breed characteristic of rabbits, but also has specific economic value, social needs and market preferences. [0003] Most of the black rabbit breeds in my country are small and medium-sized rabbits. For example, the adult weight of the Wanzai rabbit is 1.75-2.25kg, the adult weight of the southwestern black rabbit is 2.2-3.0kg, and the adult weight of the Laiwu black rabbit is 3.8-4.3kg. Generally, the growth is slow. , the production performance is low...
