生猪生产的周期性影响生猪价格周期的规律是：从价格高峰至价格低谷或从价格

The cyclicality of hog production affects the law of the hog price cycle: from price peak to price trough or from price trough to price peak, it takes about 1.5 years (peak to peak or peak to peak); from price peak to price It takes about 3 years to reach a peak or from a low price peak to a low price peak (peak-to-peak or peak-to-peak). With reference to the schematic diagram of the pig production cycle, it takes at least 18 months or 1.5 years from the start of sow breeding, to sow breeding, pregnancy, lactation, piglet care, fattening, and slaughter. Due to the hysteresis of pig production and the asymmetry of market information, cyclical fluctuations in meat prices have occurred: producers expand their breeding scale to raise sows and purchase piglets when pig prices are at their peak, causing piglet prices to rise; At 18 months, live pigs began to be slaughtered. Due to supply and demand, the number of hogs on the slaughter increased, and the number of slaughters increased. The supply of sows caused an oversupply of piglets. As a result, the price of live pigs was at a low level. At this time, sows were eliminated and the number of breeding sows decreased. After another 18 months, the number of live pigs on the slaughter is reduced, and the number of slaughters is reduced. Due to the supply and demand, the price of live pigs is at a peak. As the previous round of overproduction caused the next round of underproduction, the market meat price continued to fluctuate

The law that the periodicity of pig production affects the price cycle of pig is: it takes about 1.5 years (from peak to peak or from peak to bottom) from peak to trough or from trough to peak; it takes about 3 years (from peak to peak or from peak to peak) from price peak to price peak or from low price to low price. According to the schematic diagram of pig production cycle, it will take at least 18 months, i.e. about 1.5 years, from sow breeding to sow breeding, pregnancy, lactation, piglet care, fattening and marketing. Due to the lag of pig production and the asymmetry of market information, there are periodic fluctuations in meat price: when the pig price is at the peak, the producers expand the breeding scale, breed sows and buy piglets, resulting in the price rise of piglets; after 18 months, the live pigs began to be put on the market, due to the relationship between supply and demand, the number of live pigs on hand increased, the number of sows on the market increased, and the sows gave birth to piglets As a result, the price of live pigs is at a low point. At this time, the number of sows to be bred will be reduced. After 18 months or so, the number of live pigs on hand will decrease, and the number of live pigs will be reduced. Due to the relationship between supply and demand, the price of live pigs will be at a peak again. Due to the previous round of overproduction resulting in the next round of insufficient production, the market meat prices continue to fluctuate
