Ruminants are unique mammals that can convert the energy in roughage to edible products for humans. Hence, rumen fermentation has been excessively on the scope of researchers for long years. Advances in rumen fermentation are a vital concern to provide food with good quality for the growing population of man. This review focuses on physiology of rumen fermentation and the recent advances in the field.
