Embodiment 1

[0037] This embodiment protects and utilizes the breeding method of the breed resource of Gushi chicken, such as figure 2 , the specific steps are:

[0038] (1) Local chicken conservation breeds

[0039] The original ecological stocking of Gushi chicken breeds is implemented, and no artificial selection is made to ensure that their inherent characteristics remain unchanged. One generation per year, pure breeding and original ecological stocking, and at the same time establish a conservation base in different places to carry out dual conservation in different places. To maintain the population size, each generation should not be less than 2,000 hens and 200 roosters. Repeating this process can achieve the purpose of protection. In addition to breeding the above-mentioned protected population for the next generation every year, another purpose of the preserved population is to breed roosters for production, which is the utilization of local chickens;

[0040] (2) Local chick...

Embodiment 2

[0044] The protection and utilization method of local chicken Xichuan black-bone chicken variety resource of this embodiment, such as image 3 As shown, the specific operation steps are as follows:

[0045] (1) Local chicken conservation breeds

[0046] The original ecological stocking of the Xichuan silky breed is implemented, and no artificial selection is made to ensure that its inherent characteristics remain unchanged. One generation per year, pure breeding and original ecological stocking, and at the same time establish a conservation base in different places to carry out dual conservation in different places. To maintain the population size, each generation should not be less than 2,000 hens and 200 roosters. Repeating this process can achieve the purpose of protection. In addition to breeding the above-mentioned protected population for the next generation every year, another purpose of the preserved population is to breed roosters for production, which is the utiliz...

Embodiment 3

[0054] This embodiment protects and utilizes the breeding method of the genetic resources of Changshun green-shell hens, such as Figure 4 , the specific operation steps are as follows:

[0055] (1) Preservation of local chicken breeds: the Changshun green-shell layer hens are stocked in the original ecology, and no artificial selection is made to ensure that their inherent characteristics remain unchanged. One generation per year, pure breeding and original ecological stocking, and at the same time establish a conservation base in different places to carry out dual conservation in different places. To maintain the population size, each generation should not be less than 2,000 hens and 200 roosters. Repeating this process can achieve the purpose of protection. In addition to breeding the above-mentioned protected population for the next generation every year, another purpose of the preserved population is to breed roosters for production, which is the utilization of local chi...

Abstract

The invention discloses a breeding method for local chicken variety resource protection and utilization, and belongs to the technical field of poultry breeding. According to the method, the local chicken variety resources are not manually selected, and the inherent characteristics of the original variety keep unchanged. During the utilization in each year, 12-week old cocks with the average body weight being 95 percent to 107 percent are selected and remained in a seed reserving group, and are subjected to hybrizing matching with cultured high-breeding-property or fast-growth new strains (matched strains), the appearance characteristics of the original local chickens are reserved, the egg laying performance/growth speed of the local variety is improved/accelerated by 15 to 20 percent. The method provided by the invention has the advantages that the original local variety is used as the strain for participating in the matching, the damage of current variety breeding or pure hybridization to resources in the past local chicken resource development and utilization is avoided, and the duplex effects of protection and utilization are achieved.

Description

technical field [0001] The invention belongs to the technical field of poultry seed production, and in particular relates to a breeding method for protecting and utilizing local chicken breed resources. Background technique [0002] Our country has a vast territory, diverse geographical, ecological and climatic conditions, coupled with numerous ethnic groups and different living habits, it has bred rich and colorful genetic resources of livestock and poultry. At present, there are 107 local chicken breeds in China. These local chicken breeds have distinctive body shape and appearance, and are obviously superior to foreign breeds in terms of adaptability, disease resistance, and meat and egg flavor, and contain huge genetic diversity. They are new chicken breeds. An inexhaustible source of variety innovation. However, there has long been a contradiction between protection and utilization. Due to the pure pursuit of quantity and short-term benefits, some production units foc...
