I'm going to buy piglets for fattening, and raise 50 pigs in the first batch. Experienced friends will tell me if there is any profit margin.

At present, the profit margin of feed price and piglet price is around 250-300 yuan. If a batch is slaughtered every 4-5 months and 50 piglets are raised in each batch, the profit will be 1- 1.5 million yuan. If you have other incomes, you can raise them. For example, if full-time pig farmers earn less, they might as well work, because they don't have to bear the risk of breeding and don't need to invest capital.
