Problems solved by technology

If the conservation method is improper, it will lead to the degeneration of the species, and finally it will be difficult to reproduce
At present, the international and domestic research on local poultry species conservation methods is still in the exploratory stage, and there is no practical method to apply them. Some poultry farms use a large number of groups to preserve species, resulting in a waste of manpower and material resources
In some conservation farms with weak economic strength, due to the small population and imperfect conservation methods, the species are endangered

Embodiment 1

[0007] (1) Divide the original conservation population into several families according to the appropriate male-to-female ratio.

[0008] (2) When breeding the next generation, select roosters and hens for breeding according to each family, and carry out breeding in turn during breeding, that is, use the cock of the No. 1 family to match the hen of the No. 2 family, and the hen of the No. 2 family. The rooster is paired with the hen of family No. 3, the rooster of family No. 3 is paired with the hen of family No. 4, ..., and the rooster of the last family is paired with the hen of family No. 1.

[0009] (3) According to the pedigree, the rooster and the hen that are bred from generation to generation are reorganized into a new family;

[0010] (4) Repeat steps 1-3.

Embodiment 2

[0012] (1) Divide the original conservation population into several families according to the appropriate male-to-female ratio.

[0013] (2) When breeding the next generation, select roosters and hens for breeding according to each family, and carry out breeding in turn during breeding, that is, use the cock of the No. 1 family to match the hen of the No. 2 family, and the hen of the No. 2 family. The rooster is paired with the hen of family No. 3, the rooster of family No. 3 is paired with the hen of family No. 4, ..., and the rooster of the last family is paired with the hen of family No. 1.

[0014] (3) When the next generation is subcultured, use the cock of the No. 1 family to match the hen of the No. 3 family, the cock of the No. 2 family to match the hen of the No. 4 family, and the cock of the No. 3 family to match the hen of the No. 5 family. Hens, in turn.

Embodiment 3

[0018] (1) Divide the original conservation population into several families according to the appropriate male-to-female ratio.

[0019] (2) When breeding the next generation, select roosters and hens for breeding according to each family, and carry out breeding in turn during breeding, that is, use the cock of the No. 1 family to match the hen of the No. 2 family, and the hen of the No. 2 family. The rooster is paired with the hen of family No. 3, the rooster of family No. 3 is paired with the hen of family No. 4, ..., and the rooster of the last family is paired with the hen of family No. 1.

[0020] (3) When the next generation is subcultured, use the cock of the No. 1 family to match the hen of the No. 3 family, the cock of the No. 2 family to match the hen of the No. 4 family, and the cock of the No. 3 family to match the hen of the No. 5 family. Hens, proceed in this way in turn.

Abstract

The invention relates to a poultry variety preservation method which is implemented by selectively breeding by turns among family generations. The method comprises the following steps: (1) original variety preservation populations are divided into a plurality of families with appropriate male / female matching ratio, and the families are numbered from No.1 to No.n; (2) during the next generation breeding process, a rooster in the No.1 family is mated with a hen in any one of the N0.2 to the No.n families, a hen in the No.1 family is mated with a rooster in any one of the N0.2 to the No.n families, the rooster and the hen of two different families are mated, and the genetic diversities of the rooster and the hen of the two mating families are different; (3) the previous step of next generation breeding is repeated, the two families for mating are different at each time of breeding, and the genetic diversities of the rooster and the hen of the two mating families are different; (4) the sub-breed of rooster and the sub-breed of hen are re-organized to form a new family according to the family tree; and (5) the step (1) to the step (4) are repeated. The invention can ensure that the biological characteristics of the variety preservation population remain relatively stable.

Description

technical field [0001] The invention relates to a method for preserving poultry species, in particular to a method for preserving species by "the method of selection and selection between generations in a family". Background technique [0002] The key issue of poultry conservation is to maintain the relative stability of heredity and adaptability of the population in the long term. However, when it comes to issues such as group size, mating system, and seed retention methods, it may cause a decline in the quantitative traits of the preserved population within a certain period of time with the increase in inbreeding of the preserved population. If the conservation method is improper, it will lead to the degeneration of the species, and finally it will be difficult to reproduce. At present, the international and domestic research on local poultry species conservation methods is still in the exploratory stage, and there is no practical method to apply it. Some poultry farms us...
