Breeding method of new Jilin black pigs

Abstract

The invention discloses a breeding method of new Jilin black pigs. The method comprises the following steps: establishing a Min pig base group for propagation, and selecting purified Min pigs meeting requirements; establishing a breeding base group: hybridizing the purified Min pig sows with American Berkshire boars, selecting hybrid pig individuals with all black hair color, establishing an F1 group with clear blood relationship, selecting sows in the F1 group to continue to hybridize with the Berkshire boars to produce an F2 group, and establishing the breeding base group; selecting a breeding core group: selecting 200 sows and 10 boars meeting requirements from the breeding base group to form the breeding core group, and combining genome selection from the breeding core group with a conventional breeding technology to select for multiple times to obtain a black pig core group; and carrying out generation breeding to obtain the black pigs meeting the requirements according to the determination result and the appearance scoring condition. The black pigs have the advantages of being high in litter size, good in meat quality, high in lean meat percentage, fast in growth and development, capable of meeting consumption requirements of China and the like.

Description

technical field [0001] The invention relates to the technical field of black pig breeding, in particular to a method for breeding new Jilin black pigs. Background technique [0002] Due to differences in consumption patterns and eating habits, consumers in my country have very different requirements for pork quality from those in European and American countries. They have diversified needs for the taste and flavor of pork. However, the pig products provided by the current pig production are very different. Single, it is difficult to adapt to the future development of the pig consumption market. The breeds used to produce pork in the domestic market are mainly imported breeds, which are in line with the mainstream direction of live pig production, pursuing growth speed and ignoring meat quality; mainly local breed pigs are used for medium and high-end pork production, but Local pigs have low lean meat rate, slow growth rate and small scale. The rapid development of the marke...

[0002] Due to differences in consumption patterns and eating habits, consumers in my country have very different requirements for pork quality from those in European and American countries. They have diversified needs for the taste and flavor of pork. However, the pig products provided by current pig production are very different. Single, difficult to adapt to the future development of the pig consumption market

The breeds used to produce pork in the domestic market are mainly imported breeds, which are in line with the mainstream direction of live pig production, pursuing growth speed and ignoring meat quality; mainly local breed pigs are used for medium and high-end pork production, but Local pigs have low lean meat rate, slow growth rate and small scale

Due to the lack of specialized pig breeds for medium and high-end pork production, the rapid development of the market is seriously restricted
