Livestock production in Iowa as related to hay and pasture
( 2017-08-24) Wilcox, Walter ; Extension and Experiment Station Publications

Iowa farmers have been growing too much corn. Iowa farm land simply will not stand as large a corn acreage as was devoted to it just prior to 1934. This conclusion is borne out by both the research* of the Agricultural Experiment Station and by estimates made by farmers in their County Land Use Planning reports.**

But if less corn is grown, what effect will this change in crops have upon the kinds and numbers of livestock produced?

Ever since the AAA started its first program in the Corn Belt, one of the questions uppermost in the minds of both farmers and AAA planners has been: What will less corn and more grass do to hog, beef and dairy production? Within the Corn Belt farmers have been concerned chiefly about the influence of less corn upon hog supplies. Will a soil conservation program with its reduction of soil depleting crops hold hog numbers sufficiently in check to avoid a recurrence of large surpluses and low hog prices? Outside of the Corn Belt some apprehension has been expressed by dairy and cattle interests. They ask: “Will not the curtailment in concentrates and the rise in roughages promoted by the AAA programs shrink sow herds and add to the number of cows that are kept on Corn Belt farms?”
