First of all, raising pigs is very expensive. People in mountainous rural areas seldom feed pigs with any feed and additives, but they must have enough food to feed them. Cereals, such as corn, vegetables and potatoes, work hard at home, and almost all of them are used to feed pigs, and it takes a long time to feed pigs. If they don't buy feed and additives for pigs, the pigs raised by ordinary rural people can only be sold for at least one year. In the past few years, the price of live pigs has been low. The income from selling pigs offset the cost of feeding during this period, and the profit was quite low.

Second, raising pigs is risky. First of all, it is obviously unrealistic for rural families to raise their own sows. So if they want to breed, they must buy piglets. The price of a pair of piglets is not cheap, at least a few hundred yuan. At the same time, we should also do a good job in epidemic prevention. If we don't pay attention, hard-working pigs will get sick or infected with plague and lose all their money.

Third, many migrant workers go out to work. As far as our village is concerned, this village is very small, with only dozens of families. In recent years, it is difficult to support a family and their children to go to school through traditional agriculture in mountainous rural areas. As a result, most young people and middle-aged people choose to go out to work, leaving only the old, the weak and the sick in the village. In this case, few people in the village raise pigs, even if there are.

In the long run, rural people are also thinking. Instead of raising pigs, it is better to buy pigs directly and free up manpower, money and time to do other things. As a result, the traditional habit of raising pigs in rural households has gradually changed.
