In vitro batch cultures were grown to investigate the effect of different energy levels and corn processing diets on ruminal fermentation parameters in a 2×2 factorial experiment. Isonitrogenous diets were constructed with a concentrate-to-forage ratio of 65∶35 using corn straw as the main forage and corn silage and rumen-protected fat were added to adjust the diets’ energy levels. In addition steam-flaked corn and ground corn were tested as different corn processing products. The results showed that the theoretical maximum gas production 48 h total gas production and dry matter degradability of the high-energy diets were significantly higher than for the low energy diets (P
