Considerable work has been done at the Iowa Agricultural Experiment Station on corn-protein substitution rates in hog rations and and related hog nutritional problems. Researchers in animal husbandry and agricultural economics pooled their efforts in these studies, the results of which were detailed in the February, March and April 1954 issues of Iowa Farm Science.
