Rice Husk
Rice husk is the dry outer covering of rice grain, which is always removed during the milling of rice. It is of no direct nutritional value to man and in most mills, it is often discarded or allowed to rot away. In some areas, however, it may be collected and used as litter material or used in fire-making. In spite of rice husk abundance, nutritionists have neglected the use of it in animals feed production because of its fiber content, roughness poor nutritive value, and induced irritation in the digestive tract.
