1. Description

Rice Straw is the byproduct of rice (Oryza sativa) harvesting. After the grains are removed, the remaining stalks and leaves are collected as straw. It is widely used as roughage in livestock feed, particularly in regions where rice is cultivated. Although low in protein and digestibility, it serves as an economical feed source, especially for ruminants like cattle and buffaloes. To enhance its nutritional value, it is often treated with urea or mixed with other high-protein feed ingredients.
