Feed resources are very important for livestock production,
especially during the dry season in the tropical area. The
scarcity of feed has been critically exerting in terms of
quantity and quality, particularly protein sources which
result in low productivity. Rice straw is the main cropresidue
which farmers usually store for use as ruminant feed
in tropical areas, especially in Asia. However, rice straw is low
in nutritive value with low level of protein (2–5%DM), high
fiber and lignin content (NDFN50%), low DM digestibility
(b65%) thus resulting in low voluntary feed intake
