Want to see how much additional profit you can make by having your cows produce another pound of milk per day (factoring in feed and other variable costs)? Or, how much the value of a cow changes with changing milk price and feed cost?

Faculty member David Galligan and others have made the program visual by using gauges — like the gauges on a car’s dashboard — to tell you what’s happening to profitability.   You can access the site by following this link.
