Embodiment 1

[0017] Embodiment 1 The breeding method of the cold-resistant rabbit of the present embodiment, comprises the following steps:

[0018] (1) Four generations of purebred cold-resistant breeding rabbits introduced from Russia, Soviet Chinchilla rabbit and Vienna sky blue rabbit, formed specialized strains;

[0019] (2) Select 50 female rabbits with large skin, obvious estrus, and good motherhood and 15 Viennese sky blue male rabbits with large physique, good meat production performance, and high coat density for crossbreeding. After 3 times of breeding, the F1 generation was obtained Hybrid population;

[0020] (3) In the F generation, 100 female rabbits with large skin, obvious estrus, and good motherhood were selected, and they were backcrossed with 30 Viennese sky blue male rabbits. After three times of breeding, the F2 generation hybrid group was obtained;

[0021] (4) In the F2 generation, select male rabbits with large physique, good meat production performance, and high ...

Embodiment 3

[0029] Embodiment 3 The breeding method of the cold-resistant rabbit of the present embodiment, comprises the following steps:

[0030] (1) Four generations of purebred cold-resistant breeding rabbits introduced from Russia, Soviet Chinchilla rabbit and Vienna sky blue rabbit, formed specialized strains;

[0031] (2) Select 50 female rabbits with large skin, obvious estrus, and good motherhood and 15 Viennese sky blue male rabbits with large physique, good meat production performance, and high coat density for crossbreeding. After 3 times of breeding, the F1 generation was obtained Hybrid population;

[0032] (3) In the F generation, 100 female rabbits with large skin, obvious estrus, and good motherhood were selected, and they were backcrossed with 30 Viennese sky blue male rabbits. After three times of breeding, the F2 generation hybrid group was obtained;

Abstract

The invention belongs to the technical field of breeding of meat rabbits, and relates to the breeding method of cold-resistant rabbits. The method comprises the first step of breeding cold-resistant breeding rabbits the Soviet union Chinchillas introduced from Russia and Vienna azure purebred rabbits for four generations respectively to form specialized strains; the second step of choosing Chinchillas doe and Vienna azure buck to conduct hybrid to produce an F1 generation; the third step of choosing doe which are expanding in skin, obvious in oestrus and good in maternity in the F1 generation to conduct backcross on the Vienna azure buck to generate an F2 generation; the fourth step of choosing buck which are large in physique, good in meat yield performance, and large in hair density in the F2 generation with doe which are expanding in skin, obvious in oestrus and good in maternity to conduct crossing to obtain an F3 generation; the fifth step of repeating the fourth step till a meat rabbit new strain in which the rabbits are basically consistent in body form and appearance, stable in genetic performance, and good in cold resistant performance is bred. The breeding method of the cold-resistant rabbit is simple and feasible, the breeding time is short, the cost is low, the new-strain rabbits are strong in reproduction capability, large in growth speed, high in adaptability and high in economic benefit.

Description

technical field [0001] The invention belongs to the technical field of meat rabbit breeding, and relates to a method for cultivating cold-resistant rabbits. Background technique [0002] The suitable ambient temperature for the growth of rabbits is 15-25°C. If it is lower than 5°C, the young rabbits are easy to freeze to death. Therefore, the breeding areas of meat rabbits in my country are mainly concentrated in areas with relatively mild climate and environment; while the lowest temperature in northern my country can reach -35°C to -40°C, or even lower, the small-scale garden-style breeding model of domestic rabbits can no longer satisfy the needs of meat rabbits. The large-scale breeding of meat rabbits has not been popularized in order to meet the needs of the market and the fur market. At the same time, the cost of heating in winter is high, and there is an urgent need for cold-resistant breeding rabbits to reduce the cost of breeding and heating. Contents of the inven...
