Add to ORKGThe Utah Experiment Station has conducted a large number of feeding experiments with animals, the most extensive work in this direction being with hogs. Since the station was organized, over one hundred tests of various rations have been made and over three hundred hog;s have been fed. The results of these feeding tests are scattered through many hundred pages of reading matter in the station publications. As the continuation of these experiments fell upon the writer, it was decided to investigate thoroughly the work already done at the station and to tabulate the results for study. A summary of the results is here presented, as it is believed that they will be of considerable value and interest to the hog feeders of Utah
