When planning feeding and corresponding cropping programs, dairy farmers need information on how alternative forage bases and annual milk production rates impact on ration composition. Impact on total ration cost is also important, especially for those purchasing all feeds for their herd. The purpose of this paper is to provide dairy cow rations for alternative forage bases and milk production rates for use by dairy farmers in planning feeding programs and others interested in use of this information for research and extension purposes. The rations are based on results of a least cost balanced dairy ration computer program. This effort is a part of a larger project to develop dairy cow and heifer enterprise budgets.
