Abstract: The in vitro gas production technique was used for determine of fermentation characteristics of barley grain and corn grain. Triplicate samples were used for measuring gas production. The data were fitted by equation of P = A(1-ect) that P is gas production at time t, A is gas production of soluble and insoluble fraction, c is rate of gas production and t is time of incubation. The gas production was measured at 2, 4, 6, 8, 12, 16, 24, 36 and 48 h. The gas production of corn grain at 2 h was lower than barley grain (p<0.05), that can be resulted from slow degradation of starch in corn grain compared to barley grain. However, the sum of gas production of soluble and insoluble (a+b) in corn grain was significantly more than barley grain. The rate of gas production of barley grain was higher than the corn grain. The pattern of fermentation for corn grain differed from that in the barley grain.
