Problems solved by technology

Domestically raised meat rabbits are mainly old breeds introduced from abroad in the early years. There has been a lack of selective breeding for a long time, 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.
In recent years, Chinese enterprises have introduced commercial matching lines from abroad at high prices, but foreign breeding companies often only sell single-sex grandparent rabbits. By controlling the provenance, Chinese enterprises are forced to continuously update the introduction and continue to obtain asymmetric high profits. heavy burden on the industry
The long-term shortage of good breeds has also led to problems such as chaotic order in the breeding rabbit market, shoddy goods, and lack of standards, which have always been the bottleneck restricting the better development of my country's rabbit industry

Embodiment 1

[0034] The present embodiment provides the breeding method of described a kind of white meat rabbit three-line matching line, comprises the following steps:

[0035] (1) Select the male rabbits of the ancestor breeding rabbit GD24 of the Ipru meat rabbit matching line with obvious breed characteristics to mate with the GD14 female rabbits of the Ipru meat rabbit matching line to produce the parent generation PS19 male and female rabbits;

[0036](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 fig...

Embodiment 2

[0043] 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

[0052] The average body 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.

[0053] 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 culture method for a white meat rabbit three-line complete set line. The culture 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 closed continuous progeny selection, a specialized dam line I and a specialized dam line II are obtained; male rabbits of the specialized dam line I and female rabbits of the specialized dam line II are hybridized to produce female parent-generation rabbits; Taishan white rabbits are selected and subjected to closed continuous progeny selection to obtain a specialized sire line VI; male rabbits of the specialized sire line VI and the female parent-generation rabbits are hybridized to produce goods-generation meat rabbits. By means of the culture method, the white meat rabbit three-line complete set line with high production performance, great heterosis 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 white meat rabbits. Background technique [0002] Meat rabbit production has the characteristics of grain saving and high efficiency, high-quality products, health and low carbon, and is one of the most promising animal husbandry categories in the new century. China's rabbit meat production accounts for more than 40% of the world's total output, and it is the world's largest developing country in the rabbit industry. Shandong is the main meat rabbit production area, with the highest level of breeding scale and export-oriented degree in the country, and the export volume of rabbit meat accounts for 90% of the country. . 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 t...
