The automated feeding system for pig farms uses sensors to automatically detect the feed level in the trough. When the trough is low on feed, under microprocessor control, the feeding motor is activated to dispense feed. Once the trough is full, the sensor detects the full state, and the feeding motor stops.

1. Precise control, labor savings, increased production efficiency, and reduced breeding costs.

2. When applied to sow barns, it improves pregnancy turnover rates and reduces culling rates.

3. Combined with quantitative cup feeding, the time required to feed sows is shortened from 60–30 minutes to just 10 seconds. The feeding process is quiet, reducing stress, miscarriages, returns to estrus, and equipment damage.

4. Reduces contamination of feed and woven bags by personnel movement and rodents, keeping the feed fresh.

5. When applied to nursery and growing pigs, combined with automated ad libitum feeding, it can shorten the time to market by 10–15 days and reduce costs.

6. Reduces labor demands, increases worker retention, and stabilizes workforce quality.

7. Promotes the strengthening of the epidemic prevention system.
