Expeller Processed Soybean Oil Meal Compared with Other Protein Supplements

University of Minnesota

Abstract

The acreage of soybeans produced in the cornbelt has been increasing rapidly in recent years. The leading states of this area in soybean production are Illinois, Indiana, Iowa and Missouri. Of these states, Illinois produces by far the most beans since in 1934 this state threshed about 54% of the total United States production of soybeans. The 1935 crop of soybeans in the cornbelt exceeded the 1934 acreage by 27 per cent. If the tendency to increase the crop land seeded to soybeans continues, this plant will soon become one of the principal cornbelt crops.

A very real danger of serious damage to the quality of pork produced in heavy soybean growing areas is recognized by the Experiment Stations and valuable publicity work has been done this year to bring the problem forcibly to the attention of hog producers. In some sections mills will trade soybean oil meal for beans pound for pound. While the digestible nutrients total 94 pounds per hundredweight of beans (carbohydrate equivalent of the fat included) and the T. D. N. of soybean oil meal is 84.5, the hog feeder can well afford to use the high protein meal when the risk of soft pork is considered. In quality of protein, soybean oil meal is superior to many of the protein supplements from vegetable sources.
