Abstract

Abstract: The method used in this study was in vitro gas production. Data were analyzed using a nested randomized block design with 4 inclusion levels of condensed tannin (CT) in pollard (P) and soybean meal (SBM). The treatments consisted of P0: pollard + 0% CT, P2: pollard + 2% CT, P4: pollard + 4% CT, P6: pollard + 6% CT, SBM0 = SBM + 0% CT, SBM2: SBM + 2% CT, SBM4: SBM + 4% CT, SBM6: SBM + 6% CT. The diet consisted of maize stover and concentrate. Variables measured were in vitro cumulative gas production, b value (gas production from undissolved material but potentially degraded), and c value (gas production rate from potentially degraded material). The results indicated the highest cumulative gas production was achieved in P0 and SBM0 with 140.89 and 125.83 ml/500 mg dry matter, respectively. While the lowest one was in P6 and SBM6 with 106.10 and 100.26 ml/500 mg dry matter, respectively. The highest b value was observed in P0 and SBM0 with 154.14 and 139.01 ml/500 mg dry matter, respectively. The c value was not significantly differed among treatments. It could be concluded that the CT inclusion is beneficial to decrease in vitro cumulative gas production and b value of pollard and soybean meal.
