Armstrong Research and Demonstration Farm
A water fountain oriented cattle weight monitoring system was designed to automatically identify cattle and weigh cattle when they approached the in-pen water fountain to drink. This system provides a labor free means to monitor cattle in terms of daily weight gain and also provides an objective method to evaluate the health of cattle based on frequency of drinking and deviations from their normal pattern.
