How are digetstive systems of non ruminants able to use roughages in theie diets?

Non-ruminants, such as horses and rabbits, can utilize roughages in their diets through specialized digestive adaptations. They possess a larger cecum and colon, where fermentation of fibrous materials occurs, allowing for the breakdown of cellulose by microbial action. Additionally, some non-ruminants practice coprophagy, consuming their feces to further extract nutrients from roughages. This combination enables them to efficiently digest and benefit from high-fiber plant materials.
