Problems solved by technology

However, "Wai Sanyuan" pigs have poor adaptability in the warm and humid climate of the Guizhou Plateau, especially the high incidence of diarrhea in piglets, usually as high as 50%
In addition, citizens generally reflect that the quality and taste of "outer three yuan" pork is not as good as that of local pork

Embodiment Construction

[0029] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0030] A method for breeding Kaiyang lean-meat pigs, comprising the following steps:

[0031] A. Select 50 local brown hair waxy grain sows, and crossbreed with Landrace pig male parents to produce 50 litters of piglets. The hybrid offspring produced are selected through four selections to select excellent boars for breeding;

[0032] ①Selection for the first time: When the piglets are newborn, select individuals with good growth and development. In litters with more than 13 piglets and more than 12 live piglets, select 3 d...

Abstract

The invention relates to the field of animal breeding, in particular to a lean-meat-type pig selection method in a hybridization technique. The specific implementation steps comprise that first, local palm hair glutinous cereal pigs are selected as female parents which are crossed with boars which are landrace of an introduced variety and used as male parents, generated offspring boars are selected and are crossed with the offspring pigs generated by crossing of local glutinous cereal pigs used as male parents and large white sows of an introduced variety as female parents, excellent sows are selected as final female parents to be crossed with Duroc, and generated offspring pigs are high-quality lean-meat-type pork pigs. The novel-variety lean-meat-type pork pigs effectively overcome the shortcomings that outer-ternary piglets are high in diarrhea rate, high in meat moisture, low in unsaturated fattyacid, bad in meat flavor and the like.

Description

technical field [0001] The invention relates to the field of animal breeding, in particular to a method for breeding lean meat pigs using hybridization technology. Background technique [0002] Landrace pigs, Yorkshire pigs, and Duroc pigs are famous lean-meat pigs in the world, and they are also the main breeding breeds currently promoted in my country. In production, landrace pigs are often used as the male parent to cross with the large Yorkie pig female parent, and the offspring "Long × Big" dual hybrid sow is selected as the female parent, and the Duroc boar is used as the terminal male parent for crossing, and the "Duroc" is obtained. × long × large” three-way hybrid offspring are used as commercial meat pigs, usually called “outer three-way”. "Wai Sanyuan" has the advantages of good growth performance, high feed conversion efficiency, and high lean meat, and has become the main hybrid combination used in large-scale pig raising in my country. However, "Wai Sanyuan" ...
