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.
