- Rice straw is used as feed for ruminants and for many other uses like manure, thatching, paper pulp, alcohol, mats, poultry litter and mushroom production.
- Besides the straw, rice also produces rice polish, rice bran and rice husk. On an average, there is 20% husks, 10% bran, 3% polishings, 1- 17% broken rice and 50-66% polished rice.
- Rice straw is fed to cattle and buffaloes in India since ages. Though rice and wheat straw on average have a similar nutritive value according to laboratory analysis, in some parts of the country like Punjab, Haryana and Western Uttar Pradesh, wheat straw is preferred over rice straw. In rest of the India, paddy straw is fed to animals.
