From the developer:
CamDairy is a computer model designed to help farm advisers, farmers, students and research scientists who are interested in the nutrition of dairy cows. It can be used to predict milk production from information describing the physiological status of cows and the feeds offered to them. This is a valuable way of identifying constraints to production.
