President's Address—The Mineral Metabolism of the Milch Cow

E. B. Forbes

Ohio Agricultural Experiment Station

Abstract

Inasmuch as an important feature of the work of the Society at this time is the improvement of methods of experimentation, the President has chosen to present as his annual address a technical paper, as much to present a statement of methods and requirements as of the results of this particular investigation.

Introductory.—For rapidity and efficiency of production of proteid and mineral nutriment, the dairy cow constitutes a class by herself greatly superior to any of the other farm quadrupeds; and since the cow is only a transformer, but in no sense a creator of these nutrients, her maximum metabolic activities depend upon as unusual requirements for the kinds of nutriment especially involved.

The unusual requirement of the cow for protein in the ration is universally recognized, and receives the attention which its importance demands. The mineral requirements of the milch cow, however, have received but scant attention.
