The MilkBar™ 20 teat free standing feeder is ideal for large pens. The feeder bowl locks onto the base stand whilst calves are feeding and allows bowl and base to be moved as one unit between pens; for transport and storage the feeder bowl stacks inside the base. The shape of the base stops' calves bunting the unit over. The Milk Bar 20 can be used inside or out; for windy conditions drill a few holes around the base and peg it to the ground!
