ChinaSoil pigsThe history of breeding can be traced back to more than 9,000 years ago in Wuyang Jiahu site, Guilin Piyan site, Xushui Nanzhuangtou site and other placesArchaeologyDiscovering. These pork bonesFossilsThe excavation proves that the Chinese began to raise pigs as early as 9,000 years ago. In the course of this long history, ChinaSoil pigsCarrying people's expectations and harvests, it has become an indispensable part of it.
ChinaSoil pigsThe complexion is dark and rough, which is slightly different from the usual image of pigs. With the evolution of history, the Chinese ancestors gradually mastered the pig raising technology, and the pig raising technology in the Yin Shang period became more and more mature. During the Han Dynasty, China's high qualitySoil pigsIt spread abroad through the Silk Road and became an extremely popular breed at the time. And during World War II, ChinaSoil pigsIt also played an important role, because the long and moderate mane on its back and neck is very resistant to moisture and has a certain toughness, so it was made into a brush for maintaining guns, the quality is reliable, and it is also listed as a Class A strategic material by the United States. China, so to speakSoil pigsmade a great contribution to the victory of the war.
After entering the era of peace, ChinaSoil pigsGradually became popular due toEconomyThe level is not high, and people generally have their own raisingSoil pigsand pork as the staple food. Soil pigsThe meat is delicious and has a unique taste, which is very popular at the family table. However, with the rapid development of society and the improvement of people's living standards, the foreign pig'sFarming techniquesand types gradually entered the Chinese market and became the mainstream.
With domesticEconomyWith the development of the development and the improvement of living standards, people's demand for pork is getting higher and higher, and in order to cater to the market demand, China has introducedDuroc pigs, Berkshire Pig andLandrace pigsand other high-quality varieties that make ChinaSoil pigsThe market share is gradually decreasing. According to the data, 98% of the pork that appears on our tables today is foreign porkDuroc pigsThe market share of meat is 31%, and the market share of Berkshire pork is 27%.Landrace pigsThe market share of meat is 40%, while ChinaSoil pigsIt only occupies 2% of the market share.
So why ChinaSoil pigsFaced with such a dilemma?On the one hand, the cultivation cycle of foreign pork is shorter, about 6 months, whileSoil pigsThe cultivation cycle has reached one year. Due to the different breeding cycles, foreign pigs are significantly better than China in terms of efficiencySoil pigs。Foreign pigs consume every 5 cattiesFeedcan gain 2 pounds, and ChinaSoil pigsIt takes 7 pounds to consumeFeedto gain 1 pound. Pigs'Feed-to-meat ratioFor 25:1, and ChinaSoil pigsofFeed-to-meat ratioFor 35:1, which makes foreign pigs have obvious advantages in terms of feeding efficiency. On the other hand, ChinaSoil pigsThe fat content is as high as 60%, while the fat content of foreign pigs is only 40%. withVegetable oilWith the popularity of pork and the decrease in people's demand for pork fat, the amount of meat has become a more important factor for consumers to consider when choosing pork.
Therefore, due to changes in business purposes and market demand, ChinaSoil pigsAlmost extinct or on the verge of extinction in the last 30 years. The decrease in market share and the decline in the number of people make ChinaSoil pigsFarming has become a restricted area.
Despite the ChineseSoil pigsSerious challenges are faced, but China** and experts remain committedin ChinaSoil pigsof protection and reproduction. As early as 1996, China introduced relevant policies to protect ChinaSoil pigs。In 2010, China established 80 of themSoil pigsSeed farms, 3Soil pigsGene bank and 37 local pig reserves, for:Soil pigsprovides strong support.
In addition, Chinese experts are still rightSoil pigsEfforts to improve genes. ChineseSoil pigsHistorically, the genes have been combined with the genes of foreign excellent breeding pigs, so they have great potential for excellent breeds. In recent years, through genetic improvement, someSoil pigsThe variety has been significantly improved. For example, the lean meat rate of Jinwu pig is as high as 56%, and Guangdong small-eared flower pig has created the "No. 1 Black Pig" through breeding, which not only has a short slaughter time and a high lean meat rate, but also has a significant improvement in the taste of meat quality.
However, there are still some problems and challenges in China's pig protection work. On the one hand, despite the introduction of relevant policies, there are still problems that lag behind transportation, facilities and technology at the implementation level. Soil pigsProtected areas and bases often lack the necessary facilities and conditions to provide adequate protection and breeding environments. On the other hand, due toSoil pigsThe breeding cycle is long and the benefit is relatively low, a lotFarmersIt is common to choose to breed foreign pigs. leads to ChinaSoil pigsThe scale of breeding is relatively small, and the number cannot meet the market demand.
To sum up, ChinaSoil pigsAs a unique pig breed in China, it condenses the long history of the Chinese nation and pigsCulture, which has very important conservation value and significance. Despite the pressure of foreign pig invasion and market competition, the efforts and continuous protection work of China's experts and experts have contributed to ChinaSoil pigsThe future of protection offers a glimmer of hope. I believe that under the attention of the ** and the people, ChinaSoil pigsIt will continue to be passed on and become the Chinese nationCulturean important part.
