Embodiment Construction

[0011] The present invention will be described in further detail below in conjunction with accompanying drawing, but not as any restriction to the present invention

[0012] Embodiment of the present invention: a breeding method for a new hybrid strain of white-washed pigs. In a farm in Shibing County, Guizhou Province, the time was March 2014. When selecting white-washed pigs, the halothane gene of white-washed pigs should be detected first , and the white-washed pig used as the male parent in step 2) and the white-washed pig used as the female parent in step 1) cannot be related within six generations.

[0013] 1) The white-washed pig is used as the female parent and the Sutai pig is used as the female parent to carry out crossbreeding, and the F1 generation of the hybrid bred is Baisu binary pig;

[0014] 2) Using the Baisu binary pig as the female parent, and using the white-washed pig of a different strain from the white-washed pig in 1) as the male parent, crossbreed to ...

Abstract

The invention discloses a method for breeding a hybrid new strain of a Baixi pig. The Baixi pig and a Sutai pig are used for hybridization to introduce the high-reproduction characteristic of the Sutai pig. Meanwhile, the Sutai pig has the characteristics of the high growth speed and high meat factor of Duroc, and a Baxi-Sutai hybrid pig is obtained through hybridization of the Baixi pig and the Sutai pig to increase the growth speed and meat factor of the Baixi pig. However, due to the fact that the meat quality of the Sutai pig is poorer than that of the Baixi pig, on the basis of obtaining the Baixi-Sutai hybrid pig, a Baixi pig different from a hybrid female parent is introduced to improve the meat quality, and finally a targeted strain Baixi-Sutai pig is obtained through transverse fixed mating of the Baixi-Sutai hybrid pig. The finally-obtained Baixi-Sutai strain has the high-reproduction gene of the Sutai pig, the fast growth gene of Duroc and the local feature gene of the Baixi pig; according to the strain pig, the features of low reproduction and slow growth of the Baixi pig are relieved, the reproductive performance is improved, the growth speed is increased, meat is delicious, fine and smooth and mellow, and economic value and breeding value are guaranteed.

Description

technical field [0001] The invention belongs to the technical field of animal husbandry, and in particular relates to a method for cultivating a new hybrid strain of white-washed pigs. Background technique [0002] As a fine local variety, whitewashed pigs have the characteristics of pure genes, early maturation, resistance to rough feeding, obvious estrus, delicious meat, low cholesterol, and fine meat quality. Slow, small litter size, low economic benefits and other shortcomings, thus affecting its further promotion and breeding. Contents of the invention [0003] The purpose of the present invention is to provide a method for cultivating a new hybrid strain of white-washed pigs. The pigs obtained through this method have the advantages of fast growth and strong reproductive performance, and the meat is delicious, delicate and mellow, which ensures economical and breeding quality. value. [0004] The present invention is achieved in that the method for cultivating a ne...
