The United States began to implement the scientific and large-scale production mode of raising pigs in the 1990s. All kinds of advanced pig-raising equipment went into pig farms to realize accurate feeding and data nutrition supply. One person can easily raise 3,000 pigs. The advanced technology in the United States will be reflected in the construction of pig houses. For example, the floor is completely watertight (to ensure the cleanliness of the pig farm), the pig house is completely closed (to ensure the safety and hygiene of the pig farm), and the disease control of the pig farm in the United States is relatively in place. Many diseases in the United States have been negative, such as swine fever, pseudorabies and foot-and-mouth disease, which have been purified in the United States, and the cost of these vaccines can be saved.

Compared with China, the biggest advantage of the United States is the construction of pig farms: modernization, high mechanization coverage, pig raising mode, environmental control system, manure treatment system and animal welfare. The United States lacks labor, and the most expensive thing is labor. In order to obtain high profit and high output, this pig breed is very important, such as Landrace, Yorkshire and Duroc, and its feed reward is very low, generally around 2.3 ~ 2.5: 1.

Low feed cost: the United States is vast and sparsely populated. Corn and soybeans are planted on a large scale and basically mechanized. The production cost of corn and soybean is very low, so the feed cost of raising livestock and poultry is relatively low, and the production cost of fat pigs is relatively low. Then there will be fewer human diseases, and it will be more convenient to detect in many aspects. First of all, there is no African swine fever; As we have done in the past two years, on the one hand, various kinds of disinfection have increased immunity, and the cost of a pig has increased by at least 30-50 yuan.

In terms of corn price, Chicago corn futures price closed at 365.2 cents/bushel on Tuesday, and a bushel of corn was equal to or equal to 25.40 kilograms, equivalent to about RMB 1006.46 yuan/ton, while the domestic corn futures price on that day was about 2450 yuan/ton.
