Enzyme-soluble organic matter (ESOM) of 167 Austrian grass silages was measured using the cellulase reference method, also predicted by near-infrared spectroscopy (NIRS) and a general linear model (GLM) based on chemical parameters. NIRS calibration showed much higher accuracy (R² = 0.90) than GLM (R²=0.57). Results indicate that NIRS is a reliable and cost-effective method for estimating ESOM in grass silage.
