Hybrid breeding production method of high-quality wild boars

Abstract

The invention discloses a hybrid breeding production method of high-quality wild boars. Northeast wild boars individuals are adopted as a male parent, high-quality Sutai pigs are adopted as a female parent, in the first stage, the Northeast boars are hybridized with the Sutai pigs, female boars are selected from the produced offspring to constitute a first-generation female pig core group, marked as an F1-generation female pig core group; in the second stage, the F1-generation pig core group is adopted as a female parent, high-quality Landrace pigs are adopted as a male parent, hybridization is conducted, the produced offspring are bred, and a second-generation pig group is constituted, and marked as an F2-generation pig group. By conducting hybridization between Northeast wild boars as the male parent and Sutai pigs as the female parent, the F1 generation is obtained, then by conducting hybridization between the F1 generation as the female parent and the Landrace pigs as the male parent, the F2-generation pig group is obtained, since the F2 generation contains 25% of the Northeast wild boars bloodline and 50% of the Landrace pig bloodline, the hybrid bred F2-generation pig group both keep the nutrient advantages of the wild boars that the pure wild boars are high in adaptability and are resistant to coarse fodder, have three highs and one low (high in protein, amino acid and linoleic acid contents and low in fat content) and the advantages of domestic pigs that the temperament is gentle, the fertility is high, the growth is fast and raising is easily conducted.

Description

technical field [0001] The invention relates to a method for cultivating new pig strains, in particular to a method for producing high-quality wild boar by crossbreeding. Background technique [0002] Pork has always been the main source of meat for Chinese residents, and plays an important role in the national economy and people's livelihood. In the 1970s, due to the limitation of productivity development level and people's living standards, pork once became the most important source of high-quality animal protein in people's diet. Pork accounted for 95% of my country's total meat output, and pork still accounts for my country's meat. More than 60% of the total output. People have a three-step process to the choice of meat consumption, namely; fatty meat type → lean meat type → high-quality flavor type. Rural and economically underdeveloped areas used to choose fat meat to meet people's energy needs, but now they have turned to lean meat; in cities and economically develop...

Problems solved by technology

[0003] At present, there is a shortage of excellent pig breed resources at home and abroad, and a few breeds of pig breeds occupy the leading position in pig production in my country. While they have some excellent characteristics, they also inherit "adaptability, Poor stress resistance, high stress response, fecundity, high-quality meat, and low lean meat percentage, especially gray, acidic, and dark meat, thicker muscle fibers, and less tenderness and taste than some local pig b...
