A feeder for feeding animals has a trough with two opposed outwardly inclined front walls over which the animals can reach for taking feed from the trough and a feed hopper for discharging feed downwardly onto a shelf above the trough. Water is supplied into the trough through a pipe along the trough underneath the shelf with a series of animal actuated nipples so that the animals may take the feed dry on the shelf or wet from the trough. A valve is provided at one end wall through which the water supply to the pipe passes, the valve having a plurality of separate orifices of different flow area and a manually operable control for selecting one of the plurality of orifices for passage of the water from the supply to the pipe.
