Since the soybean acreage has increased in Iowa and the Corn Belt, the determination of the economic feeding value of this plant deserves attention.
Alfalfa and clover have long been considered good legume hays for sheep. Because of the increase in soybean production, which involves a greater volume of soybean hay, the question naturally arises as to how this legume hay compares in feeding value with clover and alfalfa. With this question in mind four lots of pregnant ewes were experimentally fed on soybean and alfalfa hays and certain combinations of these two hays. The results secured are reported herein.
