The OSU Cowculator is a Microsoft Excel spreadsheet designed to assist cattlemen in making informed decisions associated with beef cow nutrition. Animal criteria (such as cow weight, body condition, stage of production and breed), as well as the feed and forage library can be customized to each operation or to specific scenarios within an operation.


Animal requirements and performance predictions are based on years of research data, including the 1996 and previous versions of the National Research Council's Nutrient Requirements of Beef Cattle. Classes of cattle include cows, bred heifers, growing and finishing cattle, and bulls. Cowculator does not perform least-cost formulation.
