In this video, one of our cows demonstrates the use of a frost-free nose pump, while her calf demonstrates why mother cow needs to drink so much! This pump is powered by the cow, herself. Cows learn very quickly to push on the lever to draw water up from the shallow well. After the cow is finished drinking, the pipe drains automatically to keep from freezing. No electricity is required for pumping or for keeping the water from freezing. This makes it possible to over-winter the herd far from an electric power source.
