Feeder specially designed for liquid feeding of piglets, with an easily accessible mouth so that the whole litter can eat. Manufactured without sharp edges, to avoid injuring the animals, and assembled with robotic welding to guarantee watertightness and avoid water leaks. Its manual swivel system allows it to be tilted in a vertical position for easy cleaning. It is operated with only one hand to facilitate the task and when it is finished it returns to its initial position and is blocked so that the animals cannot move it.
