I don't know if the small partners have noticed a phenomenon, the earliest common black pigs in China, I don't know from when it has rarely been seen, can see, are big white pigs?
My hometown is rural, and when I was young, my family also fed pigs, which were big black pigs. But I don't know when it started, there were fewer and fewer black pigs and more and more white pigs. When I returned to my hometown, I saw that there were pigs, and they were also white pigs. I really hadn't noticed this before, as if the black pig hadn't been seen for many years. Black pork has also become a selling point, just like Jinan's Tuhe black pig, expensive and fatal, most people can't afford to eat it. Now the famous black pig is Ding Lei of NetEase.
China's meat diet is mainly pork. I remember when I was young, I would kill pigs in the New Year. Even now, although pigs are not killed, at least you have to buy a pig's head for the New Year. China's pork consumption is twice the world average, accounting for more than half of the world, and the highest time is the 700 million pigs in a year. No wonder some time ago, a foreign politician, specifically forgot which country, said that China's pig breeding industry has a lot of air pollution to the world.
Many people don't know, and I only learned later, since the 1980s, most of the pork eaten in China is imported, and it is no longer a local pig in China, including later hybrids. White pigs like The British, american and Danish and other countries.
In other words, most of the big white pigs we see now are imported, and the real native pig breeds in China are actually black pigs. Therefore, the description of the Eight Precepts of the Pig in the Journey to the West is the Great Black Pig. And now the young director has never seen the black pig, so now many TV series in the eight precepts of the pig have also become the big white pig.
According to the 2008 survey data of the Ministry of Agriculture, 4 breeds including Hengjing pig, Shenxian pig and Xiangcheng pig have become extinct, 31 varieties are endangered, and the number of local pig breeds in about 85% of the country has shown a downward trend. So there are fewer and fewer black pigs left in the market, whether on the farm or at the table, many young people have not seen it, and they take it for granted that it is a white pig.
I have eaten tuhe black pig, the meat is tender and chewy. Listening to the elderly, basically black pigs taste like this. And many of today's young people have never seen a black pig.
So why are there fewer and fewer black pigs now?
First, because since the 1980s, with the gradual improvement of living standards, the domestic demand for pork has increased significantly. But because the growth of local pigs is slower, the size is not very large, that is, more than 100 kilograms. And the meat yield is also low, it is difficult to meet the market demand. Therefore, in order to increase the supply of pork, China began to introduce breeding pigs from abroad. Just like the most common big white pig now, the scientific name is "Yorkshire Pig". These pigs have a high meat production rate, a high lean meat rate, and a fast growth rate, and three pounds of feed can increase a pound of meat.
In terms of time, black pigs generally can only be released in one year. The white pig can be out of the pen in about 6 months. For farmers who pursue quick benefits, black pigs are indeed not cost-effective. Moreover, black pigs rarely eat feed, generally eat wild vegetables, leftovers or corn, and the cost of breeding is high.
It can not only meet the market demand, but also reduce the cost of breeding, and the advantages of imported pigs are much greater than that of local pigs. As a result, foreign breeding pigs are popular with domestic farmers, more and more farmers abandon local pigs, began to breed large white pigs on a large scale, and even many individual households and retail households will give priority to large white pigs to raise. Even if you raise black pigs, you only feed themselves.
