Problems solved by technology

Pigs bred by these methods have many problems, especially poor stress resistance and low disease resistance. This will inevitably lead to the need to feed various medicines to pigs during the breeding process, and ultimately make our food safety no good. In addition, due to the low disease resistance, pigs have high requirements on the environment and feeding conditions, which also makes the economic interests of the breeders unsecured

Embodiment Construction

[0014] In order to have a further understanding and understanding of the structural features of the present invention and the achieved effects, the preferred embodiments are used for detailed descriptions, as follows:

[0015] A method for supporting crossbreeding of parent generation sows, comprising the following steps:

[0016] (1) High-yielding Yorkshire pigs bred from Yorkshire pigs are used as the female parent, and Landrace pigs selected from Landrace pigs are used as the female parent, and then the long-growing two pigs are crossed between high-yielding Yorkshire pigs and high-yielding Landrace pigs. Yuan pigs are used as grandparent sows;

[0017] (2) Breeding Landrace pigs with fast growth speed and crossing with Red Duroc pigs, and then selecting white hybrid offspring and cross-crossing to fix them, and then breed the hybrid pigs with pure white hair gene, that is, White Duroc pigs as ancestors generation boar;

[0018] (3) Crossbreeding grandparent sows and gran...

Abstract

The invention provides a matched hybridization breeding method of a parent sow. The matched hybridization breeding method of the parent sow comprises the following steps that (1) a grown binary pig which is bred through hybridization is used as a progenitor sow; (2) a white Duroc which is bred through hybridization is used as a progenitor boar; (3) the progenitor sow and the progenitor boar are hybridized, and the parent sow is obtained. The matched hybridization breeding method of the parent sow has the advantages that the Large White, the Landrace pig and the Duroc are used as the basis of matched hybridization, a maternal line and a paternal line are bred, the fertility of the maternal line is good, paternal line is large in size, high in growth speed, good in meat quality, and high in resistance to diseases, the two-line hybridized sow which is finally obtained is high in resistance to diseases and high in stress resistance and fitter for the Chinese pig raising environment, and the economic benefits and the food safety are guaranteed.

Description

technical field [0001] The invention relates to a breeding method for raising pigs, in particular to a matching hybrid breeding method for parent generation sows. Background technique [0002] In the prior art, a popular pig raising model is to use three breeds of Duroc, Landrace and Yorkshire to carry out crossbreeding, specifically: Duroc is the terminal male parent, Landrace is the female parent, and Large Yorkshire is Pigs are matriarchal. In many cases, Landrace pigs and Yorkshire pigs can be interchanged, so that Landrace pigs are matrilineal and Yorkshire pigs are maternal paternal. Pigs bred by these methods have many problems, especially poor stress resistance and low disease resistance. This will inevitably lead to the need to feed various medicines to pigs during the breeding process, and ultimately make our food safety no good. In addition, due to the low disease resistance, pigs have high requirements on the environment and feeding conditions, which also makes ...
