| This study aimed to evaluate digestible organic matter and metabolisable energy of the total mixed ration (TMR) containing oil palm frond silage (OPFS) as a source of roughage using in vitro gas production technique. The TMR was formulated according to the ratio between OPFS (roughage) and concentrate as follows: T1 (80:20), T2 (70:30), T3 (60:40) and T4 (50:50). This study was arranged according to a completely randomized design. The rumen mixed microbes inoculums were taken from six Anglo-Nubian 50% crossbred male goats, 4-5 years old with average body weight of 43.07±3.09 kg. As the results, T3 and T4 were significantly higher in soluble gas fraction (a), fermentation of insoluble fraction (b) and potential of extent of gas production (d) values (-7.67,... |
