Utilization of Soybean Hulls When Fed in Combination with MDGS in Finishing Diets

A finishing trial evaluated the effects of feeding different levels of soyhulls with modified distillers grains plus solubles (MDGS) on feedlot cattle performance. Soyhull inclusion level was 0, 12.5, 25, or 37.5% of diet DM. As soyhulls replaced dry rolled corn (DRC), ADG decreased linearly (4.22 vs. 3.48) and F:G increased linearly in response to increasing levels of soyhulls. When comparing the feeding value of soyhulls relative to corn, feeding values decreased from 70 to 60% of corn as dietary inclusion of soyhulls increased from 12.5 to 37.5% of DM. Results show that as inclusion of soyhulls in the diet increase, ADG and F:G becomes poorer
