The objective of this study was to determine the effect of moisture content on the physical and chemical characteristics of Italian ryegrass cube. Cube quality according to moisture contents (15, 20, 25, and 30%) was determined. Cubes made with 15 to 20% moisture showed a little cracks. But, the amount of powder generate from these cubes were lower by 10 to 16% compared to other cubes made with 25 to 30% moisture contents. The highest hardness at 159 kg/f was obtained when the cube was made with 15% moisture content and the lowest was 70 kg/f when the cube was made with 30% moisture content. The electrical loading and surface temperature were increased when moisture content was decreased. The chemical compositions of cube were differ from those of raw materials. Crude protein (CP) and ether extract (EE) contents were increased after cubing works. However, crude fiber (CF), acid detergent fiber (ADF), and neutral detergent fiber (NDF) contents were decreased after cubing. The crude ash content was not significantly (p > 0.05) different between raw material and cube. Higher moisture content resulted in higher crude protein content. However, crude fiber and crude ash content were not significantly (p > 0.05) different between each other. The contents of ADF and NDF were the lowest in cubes made with 30% moisture content. Our results suggest that the proper moisture content of Italian ryegrass cubing is recommended to be 15 to 20% and that cubing works should help increase forage quality.
