With the aim to demonstrate the feasibility of calibration transfer of near-infrared spectroscopy on silage, two types of near-infrared spectrometer of Nicolet ANTARIS (master) and FOSS 6500 (slave), and two methods of slope/bias and local centering were studied. Results show that after calibration transferring the determination coefficient of calibration (R2) and determination coefficient of cross validation (R2cv) were all greater than 0.85. The standard error of prediction and bias were 20.27g/kg and －3.75, 27.67g/kg and －6.17 for slope/bias and local centering technique respectively, which were comparable with the standard error of prediction value (20.60g/kg) and bias value (－1.04) of the original model of FOSS 6500 spectrometer. These results were greatly improved from the standard error of prediction value (39.65g/kg) and bias value (－33.60) before calibration transferring. Both of the two methods of calibration transfer worked successfully.
