This 12 Teat Reservoir Calf Feeder is ideal for group hutches, training pens or calves needing some special attention. Fitted with aluminum hooks, to enable use in small pens or with multiple feeders side by side for larger groups. The durable hooks help keep feeders steady in place while you fill them. The hooks are predrilled so you can adjust them to sit on gates of 25mm - 32mm. The Milk Bar Teat controls and regulates the milk flow, evening out the speed at which calves are fed, so that no calf finishes before the others and ensures they all receive equal measures.
