Embodiment 1

[0036] The present embodiment provides the breeding method of described black meat rabbit three-line mating line, comprises the following steps:

[0037] (1) Select the healthy and obvious breed characteristics of Iprü meat rabbits, the male rabbits of the ancestor breed GD24 male rabbits, and the Iprü meat rabbit companion breeds, the ancestor breed female rabbits GD14. ;

[0038](2) BC16 male and female rabbits produced by backcrossing the PS19 male rabbit described in step (1) with the GD14 female rabbit described in step (1); The BC15 male and female rabbits were produced by handing over; the BC15 male and female rabbits were cross-propagated and multiplied to form a basic group, and 4 generations of locked-up subculture were selected, and the offspring with good adaptability, excellent production performance and reproductive performance were selected as special The mother line I system, specifically as figure 1 As shown: The coat of the specialized female line I is pure...

Embodiment 2

[0045] The difference between this example and Example 1 is that the locked-up subculture selection in steps (2), (3) and (5) is 3 generations of locked-up subculture selection, and other operations are the same as in Example 1.

experiment example

[0054] The average weight of the black meat rabbits obtained in the comparative example was 638±70.2g at the age of 35 days, 1870±261g at the age of 70 days, and the ratio of feed to weight at the age of 35-70 days was (3.31±0.16):1.

[0055] The body weight and feed consumption of the new meat rabbit strain obtained in Example 1 were measured in different weeks, and the feed-to-weight ratio was calculated, and the average value was taken, and recorded in Table 1.

Abstract

The invention relates to a breeding method of a black meat rabbit three-line complete set line. The breeding method comprises the steps that with Hyplus meat rabbit complete set line progenitor breeding rabbits and parent-generation breeding rabbits which are imported from foreign countries as experiment targets, through backcross, secondary backcross, self-reproduction and atresia continuous progeny selection, a specialized dam line I line and a specialized dam line II line are obtained; specialized dam line I line male rabbits and specialized dam line II line female rabbits are hybridized toproduce parent-generation female rabbits; black champagne rabbits are selected for atresia continuous progeny selection to obtain a specialized sire line VII line; specialized sire line VII line malerabbits and the parent-generation female rabbits are hybridized to produce goods-generation meat rabbits of the black meat rabbit three-line complete set line. By means of the breeding method, the black meat rabbit three-line complete set line with high production performance, great hybrid vigor and high adaptability can be obtained.

Description

technical field [0001] The invention belongs to the technical field of meat rabbit breeding, and in particular relates to a method for cultivating a three-line matching line of black meat rabbits. Background technique [0002] Rabbit farming plays an important role in rural regional economic development and farmers' poverty alleviation. At present, my country's meat rabbit production is transitioning from the traditional courtyard-style decentralized and extensive management to the modern large-scale intensive production mode, facing a series of industrial technical problems such as improved breeds that need to be solved urgently. The meat rabbits raised in China are mainly old breeds imported from abroad in the early years. There has been a long-term lack of selective breeding, the breeds are degraded and mixed, and the production performance is low, which greatly restricts the production level and benefits of rabbit breeding in my country. [0003] Black rabbit refers to ...
