The feeding system of circular scraper feeding equipment runs in a closed annular pipeline and communicates with the silo. When the feed tank is full, the excess feed can be recycled to the feed box. It is suitable for unlimited feeding of dry powder and granular materials, and can be realized if a metering box is configured. This kind of feeding equipment can convey feed in horizontal and vertical planes, which is beneficial to the rational layout of pigsty and mechanical equipment, avoiding feed pollution and loss, and realizing feeding automation.

The development process of mechanized pig raising can be roughly divided into three stages. At first, it was the stage of partial mechanization, that is, the individual links of pig production were mechanized, but a lot of manual labor was still needed, and it took about 25 ~ 35 working hours to produce 100 kg of pork. In the mechanization stage, the main link of pig production is basically mechanical operation, but it needs to be supplemented by a small amount of manual labor and depends on the natural environment to some extent. It takes about 12 ~ 19 man-hours to produce 100 kg of pork.

The lying area and the excreta discharge area are separated by a partition wall and equipped with movable doors that can be opened and closed. Set up a drinking machine in the excrement discharge area, open the movable door at ordinary times, and concentrate the excrement in the excrement discharge area for easy removal by using the habit of excreting urine when pigs drink water. By closing the movable door, the excrement discharge area of each pigsty can be connected into a channel, and the excrement can be removed by using the excrement scraper. This kind of pigsty can keep the sleeping area dry and clean, and reduce the waste of feed. However, because the manure discharge area is located in the pigsty, it is easy to cause air pollution in the pigsty, so the ventilation of the pigsty should be strengthened when it is used.

There are heating equipment in the conveying column, such as infrared lamp, resistance wire heater, gas heater, electric heating pad, etc. And underground hot water pipes can also be used to heat the ground. One side of the piglet activity area is provided with a feeding trough, and the other side is provided with a water dispenser on the ground. Feeding equipment is suitable for feeding dry, wet and thin materials. There are spiral conveying type, reciprocating scraper type, annular scraper type, annular chain plate type and fine material pipeline conveying type, in addition, there are automatic feeding troughs and various feeding vehicles.
