ABSTRACT:
A cattle foot-bath system, specifically adapted to mix and charge foot-bath troughs with repeatably precise quantities of chemical treatments. The system administers a concentrated medicinal agent, such as a bactericide, a fungicide, or a viruscide, for the treatment of cattle feet, and includes a day-tank feed valve, which may be a three-way or interlocked valve, for controlling an infeed flow of the concentrated medicinal agent fed into a day tank, which may be mounted to a portable tote-tank containing the concentrated medicinal agent. A day-tank drain valve controls an outlet flow of the concentrated medicinal agent drained from the day-tank, and the day-tank holds a set quantity of the concentrated medicinal agent. A footbath then receives a quantity of dilution water and the set quantity of the concentrated medicinal agent from the day-tank.
