Design and Testing of Intelligent Feeder for Piglets

In order to reduce the weaning stress of piglets and improve the palatability of feed, an intelligent piglet feeder was designed,which has been composed of feed delivery device,water supply device, arch breaker,touch switch and feed level monitoring sensor,monitoring device, etc. The equipment is simple to operate. It can automatically discharge feed and water in proportion, and sense the amount of feed in the trough to avoid excessive waste. The results of arch breaking test showed that the arch breaker could destroy the arching of powdered feed, and the feed could fall into the trough smoothly, so as to ensure the stable feeding of pigs; The feed and water discharging stability test showed that the feeding and water supplying of the feeder were stable,and the coefficient of variation of feeding and water supplying were 3.7% and 1.6%,respectively,which showed that the feeder could well control the feed and water volume each time. This study provides a reference for the research and development of piglet intelligent feeder.
