The Soybean hulls are a by-product of the extraction of oil from soybean seeds. They're light, flaky, and bulky; and extremely valuable feeds for on-farm feeding of cattle. When coming into the oil mill, soybeans are screened to remove broken and damaged beans and foreign material. The beans are then cracked, and their hulls that primarily consist of the outer coats are removed. Hulls are fibrous materials with no place in human food, however, are very valuable for ruminants. Soybean hulls are usually reintroduced within the final oil meal so as to reduce its protein content, leading to soybean meal varieties with a maximum protein & fat. However, this end use decreases once the demand for high protein soybean meal increases.
