Roughage is a type of animal feed or livestock feed. It consists of pasture grasses, hay, silage, root crops, straw, and stover (cornstalks). Therefore, it is rich in food obtained from plant materials.  Compared to concentrate, roughage has a high fibre content. But, it is low in total digestible nutrients. Roughage does not provide much energy, unlike concentrate.There are three forms of roughage as dry roughage, silage, and pastures. Dry roughages include hay, straw, and artificially dehydrated forage.
