The hand held calf nursing bottle comes complete with a peach teat and vented cap for ventilation. The Peach Teat allows no more fluid to pass through it than a cow's udder naturally would. This allows the calf to suckle more intensely than conventional technology. The Unique two-vent breather system allows for air flow. Featuring a patented internal collapsing flap-valve that holds milk in the teat.
