Method for cultivating yellow rex rabbit

Abstract

The invention discloses a method for cultivating a yellow rex rabbit. The yellow rex rabbit as a new species is cultured by using a Yufeng yellow meat rabbit and a black rex rabbit as materials through methods of hybridization, backcrossing and the like. The method disclosed by the invention has short time and high speed; the cultured rex rabbit as the new species keeps the body type of the Yufeng yellow meat rabbit, is long in back and waist, plump in rear quarters and strong and force in limbs, and has the advantages of high prophase growth speed, high feed utilization rate, strong milk secretion capacity, high breeding rate, crude feed resistance, strong premunition and the like. The cultured rex rabbit is extremely easy to distinguish from other rex rabbits, is yellow for all the body, white in belly and flat and erect in hair, has the characteristics of silky luster and difficulty in dropping of rabbit hair; the skin of the cultured rex rabbit is natural yellow and is the super fur clothes raw material in the rex rabbit industry. Because the dye process in the leather-working is overcome, the chemical pollution and the resource waste are reduced, and the requirements for environment protection and green product production are met.

Description

technical field [0001] The invention relates to a method for cultivating Rex rabbits, in particular to a method for cultivating a new variety of yellow Lex rabbit. Background technique [0002] The rex rabbits raised in my country's rex rabbit production are mainly imported from the United States, Britain and France, forming American, British and French rex rabbit strains. my country has introduced rex rabbits from the United States since the 1980s, almost every year. A lot of human, material and financial resources. The main problems at present are: (1) "Emphasis on introduction and neglect on selective breeding". Some large-scale enterprises introduce foreign species at high prices and reproduce them for multiple generations without selective breeding, which leads to inbreeding depression and decline in fur quality. (2) "Emphasis on replanting and neglecting cultivation". Some enterprises make profits by replanting and selling seeds, regardless of the source of the variety...

AI Technical Summary

Problems solved by technology

The main problems at present are: (1) "Emphasis on introduction and neglect on selective breeding". Some large-scale enterprises introduce foreign species at high prices and reproduce for multiple generations without selective breeding, which leads to inbreeding depression and decline in fur quality.

(2) "Emphasis on replanting and neglecting cultivation". Some enterprises make profits by replanting and selling seeds, regardless of the source of the variety, do not pay attention to the blood relationship of the population, let alone the cultivation of new varieties or strains, and only carry out one-level inversion The "pyramid marketing" replanting activities, the breeding rabbit market is chaotic, so far there are not many breeds or strains of rex rabbits cultivated by my country, and there are only a handful of organizations and personnel engaged in breed breeding research

(3) The phenomenon of "hybrid disorder" is serious, which leads to serious deterioration of the quality of rabbit skin

This can only make some merchants who "strive first to be strong" turn to profit, and most of the farmers who are at the bottom line of Rex Rabbit breeding are difficult to resist the risks of the market and the negative effects brought about by the decline in population quality. Rex Rabbit The quality of the hides is completely out of control
