Embodiment

[0014] A method for quickly preserving and purifying Jiangkou radish pigs, comprising the following steps:

[0015] a. Take the 30-kilometer area of ​​the core production area of ​​Jiangkou radish pig as the central ethnic group area, and select at least 10 pure Jiangkou radish pigs raised in the farmhouse to establish the central ethnic group in the central ethnic group area;

[0016] b. Select at least 200 pigs in the central population area of ​​the core production area of ​​Jiangkou radish pigs as breeding pigs, and then extend outward for more than 50 kilometers to establish an outer group, and feed the outer group according to the similar conditions of more than 70% of the mainstream farmers in the original area. The edge group and the center group together form the basic original group;

[0017] c. Every 3 years, all the central populations will be eliminated, and the appearance characteristics will be selected from the outer populations again, and then through the veri...

Abstract

The invention discloses a quick preservation and purification method for Jiangkou radish pigs. The method comprises the following steps: a, establishing a central group; b, selecting breeding pigs from the central group, establishing a peripheral group, and constituting a basic original group by the peripheral group and the central group together; c, eliminating the central group to regain a Jiangkou radish pig group with excellent meat quality, returning 50% of excellent sows determined from the descendants, raising the remaining 50% in an outer family farm 50 km away from the central group,and mating the sows of the Jiangkou radish pigs with the introduced Changbai boars to obtain piglets as commercial piglets. The method can not only effectively protect the purity and excellent qualityof the local superior pigs, but also restore the quality of the pork to the proper level, so that the utilization benefits of hybridization are reasonably reflected; the method is easy to implement,low in cost, definate in effect and good in benefit, and easily achieves the purposes of breed conservation, quality assurance and cross utilization.
