Humans can't digest roughage (eg. cellulose) because of the beta linkages that hold the glucose molecules together. Humans don't have enzymes that can break these linkages.
Roughage Is A Food Which Is High In Fibre Which The Digestive System Cannot Digest As Easy As Other Foods.
It takes the toxins out of the food
mostly because donkeys cant digest it
beacuse shane has a twelve incher
Animals that digest roughage and thrive need to have large complex stomachs and digestive systems like cows or sheep where the food (roughage) can spend a long time, being broken down by enzymes and bacterial actions and the nutrients extracted. The digestive system of a chicken is not very big, it is designed for food that has nutrients ready to be absorbed. So any roughage in the digestive system will be eliminated from the body before any nutrients can be extracted. But roughage although not a very nutrient rich item for the chicken is good for cleaning out the digestive system, just like for people.
no it cant digest its own food
Food that has too much roughage (like Bran) that is hard to digest and pass out in bowel movements
Lettuce has a large amount of roughage, therefore fruits and vegetables.
they cant
Humans lack the necessary enzyme to digest cellulose, so it acts as roughage in the intestines and helps with the digestion process
*eat They can, they just cant digest it
