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.

Important Notice for Apple Computer Users:

While we've put our best effort into ensuring compatibility across various platforms, it has come to our attention that our advanced Excel spreadsheet might encounter performance issues on Apple computers. This is a challenge known to occur with complex Excel spreadsheets on this platform. If you're using an Apple computer, please be aware of this potential limitation. We recommend checking the file's functionality and ensuring it meets your needs before relying on it for critical tasks. Thank you for your understanding!
