Embodiment Construction

[0040] The breeding method that the present invention produces beaver color type rex rabbit comprises the following steps:

[0041] (1) F 1 surrogate rex rabbit;

[0042] (2) F produced by (1) 1 The second cross between the surrogate female rex rabbit and the beaver-colored male rex rabbit is the commercial rex rabbit.

[0043] The above-mentioned beaver-colored rex rabbit requires high purity, and the beaver-colored ratio of its offspring is ≥95%; the adult weight is ≥3.5 kg, and the fur quality is good, and the coarse hair content is ≤5%. The white rex rabbit requires an adult body weight of 4.0-4.5 kg, litter size ≥ 7.5, and good fur quality, wherein the coarse hair content is ≤ 5%.

[0044] Adopt the commodity rex rabbit that the present invention produces, its breeding age will reach more than 5 months old, when fur is smooth, and is in non-moulting period, get skin.

Abstract

The invention discloses a breeding method for generating a rex rabbit in brown and beaver. The method comprises the steps that 1, a rex rabbit in beaver color serves as a female parent, a white rex rabbit serves as a male parent, and first-time hybridization is conducted between the female parent and the male parent to generate a F1 generation female rex rabbit; 2, second-time hybridization is conducted between the F1 generation female rex rabbit generated in the first step and a male rex rabbit in beaver color to generate a commodity rex rabbit. Compared with the prior art, the commodity rex rabbit in beaver color generated by adopting the breeding method is good in breeding performance, high in proportion of the beaver color in later generations, high in wool density and low in coarse wool rate. The breeding method for generating the rex rabbit in beaver color is an effective mode for breeding the rex rabbits in beaver color.

Description

technical field [0001] The invention belongs to the technical field of breeding animals, in particular to a breeding method for producing beaver-colored rex rabbits. Background technique [0002] Rex rabbit, scientific name Rex Rabbit (RexRabbit), is a world famous breed of rabbit for fur. Rex rabbit fur has the characteristics of "short, flat, dense, fine, beautiful and firm". At present, most of the color types of rex rabbits raised are white rex rabbits, and the skins of white rex rabbits need to be dyed when they are used, which will pollute the environment, and the clothes made of them may be allergic to people. And breeding colored rex rabbits (such as beaver-colored rex rabbits, blue-purple-colored rex rabbits), etc., the skin color is natural and beautiful, no dyeing is required for use, no pollution to the environment, and the risk of allergies to the human body is significantly reduced. For this reason, the development of colored rex rabbits such as beaver color ...
