Currently India is a producing 540 million tones of crop residues that include
mainly straws, stovers, dry grasses and roughages. These feed resources are high
in fiber, low in cell contents and bulky in nature. Roughage are of poor quality
in terms of palatability, diagestibility and nutrients availability and thus are
unable to med even the maintenance requirement of animals. Roughages along with
other crop residues are the main ingredients of feeding systems india and also
in most of developing nations. The poor nutritive value of these feeds is the
main hindrance in the better livestock productivity and thus improvement in the
nutritive value of such feeds
