In order to reveal characteristics of carbohydrate and protein fractions in common roughages for water buffalo,twenty kinds of roughages in four types were studied by the Cornell net carbohydrate and protein system(CNCPS).Common nutritive values of the roughages were determined.The CNCPS carbohydrate fractionations,i.e.sugars(CA),starch,soluble fiber(CB1),available neutral detergent fiber(CB2),unavailable NDF(CC) and CNCPS protein fractionations,i.e.rapidly rumen degradable true protein(PB1),intermediately ...
