Verba Speedfeeder.

The Speedfeeder is a pig feeder for large groups of fatteners or piglets
The feed is dosed via a unique dosing mechanism in which the pigs push against a tongue while they eat, which causes the feed to be dosed in small portions. So there is no spillage and this takes care for a good feed conversion. The white feed hopper is transparent, so you can check feed quantities at a glance during your inspection round. The best dose is 4 g per movement for this pig feeder.
