1. Discovering Vitamins and Trace Minerals Marker
By feeding diets of single grains to sixteen dairy heifers, University of Wisconsin scientists under the direction of biochemist E.B. Hart in 1907 set the stage for the discovery of vitamins and essential trace minerals. These feeding experiments revealed that micro-components other than fats, proteins, carbohydrates, and salts were necessary for life and reproduction. These missing components were later shown to be vitamins and essential minerals such as iron, copper, and iodine. The single-grain experiments, inspired by biochemist Stephen M. Babcock, changed forever the way scientists viewed diet and nutrition in animals and humans.Erected 2001 by University of Wisconsin Foundation.
