Under normal circumstances, the slaughter weight of pigs is about 230 kg. Some farmers will decide the slaughter time according to the local pig price, and will refuse to sell and raise for a long time when the market is good.
Just like the current pig price, the average price 13 yuan is about a kilo. If farmers' pig farms are running well and there is no epidemic disease, they will generally choose to continue feeding until they weigh about 300 kg or even higher.
However, slaughterhouses generally don't like too big fat pigs, because this kind of pig has a low lean meat rate and more fat. If the market is not good, this kind of pig will not be accepted by slaughterhouses in general, or the price will be very low.
