In order to elucidate the qualitative disposition and the quantitative distribution of the aromatic constituents in roughage, the volatile constituents of Italian ryegrass silage made in a steel silo were analyzed via a combined gas chromatograph-mass spectrometer (GC-MS) and a FID-gas chromatograph (FID-GC). The area percentage of each compound in the volatile constituents and the parts per billion (ppb) concentration of each compound in the silage were also calculated on a data processor for FID-GC using n-pentadecane as the internal standard. As a result, 26 compounds were identified from the volatile constituents of Italian ryegrass silage; their area percentages and ppm values totaled 98.3 and 1519.7, respectively. The volatile constituents of this silage were very rich in acids, of which n-butyric acid was the major constituent (79.8% and 1234ppm). Also, the acids in the solvent extract of this silage were analyzed via a GC-MS and FID-GC, and 18 carboxylic acids were identified. Similarly, n-butyric acid was the major constituent (55.3%).
