A trough is disclosed for supplying piglets with mineral supplements in the suckling period. The trough is designed to awaken the piglets' curiosity and thus make them root in the bottom of the trough, where the mineral supplements are dispensed in form of a dry powder mixture, and thus reduce spillage as compared to placing the mineral supplements on the floor of the pen. During the pre-weaning of the piglets the trough can be converted to serve as a normal trough for solid feed.
