The first edition of this publication was authored in 1894 by T.L. Haecker, University of Minnesota. This is the thirty-fourth edition of the publication and the third multistate edition. Information in this publication is intended to assist dairy producers, the feed industry and other agribusinesses in improving milk production per cow and to help the midwest dairy industry better compete on a national basis. The basic information on nutrition and feeding management for dairy animals from birth through their lactation cycles is presented here. The tables and text are based on current research data and the authors' experiences. This publication is intended as a basic reference manual and should be supplemented with fact sheets and other dairy nutrition publications as they become available from the cooperating states.
