Milk Bar 1 Calf Hanging Feeder. We just love this feeder! The easy change teat attachment does just that, makes changing teats easy. The teat sits to the outside and is fed by a super low milk channel to eliminate any milk waste. Marked gradients give full control of volume and the 1″ / 25mm hooks have a self locking catch. Features DPT – Drip Proof Technology which ensures proper feeding intake. Holds 1 gal / 4 L of milk.
