1. The first point of free-range pig raising is to buy piglets with excellent varieties and high survival rate. Generally speaking, the meat quality of free-range pigs has a great correlation with their breeds, so we should pay attention to strict control when choosing breeds, and we must choose excellent piglets that grow fast.

2. The second point of raising pigs in bulk is to do a good job in epidemic prevention, disinfection and disease removal. For new piglets, regular epidemic prevention should be carried out in strict accordance with relevant health requirements. Pig farms should establish qualified pig houses as far as possible to ensure the proper density of pigs and the normal growth and life of pigs.

3. The third point of free-range pig raising is to pay attention to material selection and feeding. Free-range pigs eat a lot and have relatively high requirements for food quality. When raising pigs, we should pay attention to feeding different kinds and qualities of feed at different growth stages and adopt scientific feeding methods.

4. The fourth point of free-range pig raising is to pay attention to environmental sanitation and disease prevention. Don't feed moldy and deteriorated feed, and pay attention to strengthening hygiene and cleanliness in daily inspection management. If pigs are found to be sick, they should be isolated and treated in time to ensure the healthy growth of free-range pigs.
