Cottonseed hulls are used mostly in the southern area of the U.S. They are low in protein, calcium, phosphorus and energy and high in fiber. Cottonseed hulls are palatable and are used as a roughage for cattle, especially in areas where good quality forages are scarce. They occasionally are included in grain mixes to increase the bulk density and crude fiber content. They can be helpful in supporting fat test in low fiber or low roughage rations.
