Problems solved by technology

[0003] With the facilitation of modern information, economy, and transportation, the abuse of hybridization methods, and the excessive pursuit of economic interests, the existing Jiangkou radish pigs have been seriously degraded and their quality has declined, making pork without the aroma of local characteristic pork; The purity of good breeds of pigs has declined seriously, making reasonable crossbreed use advantages lack of qualified male and female parents, the crossbreed use advantage has declined, and the benefit of pig breeding has been seriously affected; however, the method of breeding improved breeds according to the existing system , not only large investment and high cost, but also poor effect and benefit, often failing to reach the set goal, and even the population of Jiangkou radish pigs gradually decreased and died out, causing irreparable losses
