  We present the results of our observations of eight magnetic Herbig Ae/Be
stars obtained with the X-shooter spectrograph mounted on UT2 at the VLT.
X-shooter provides a simultaneous, medium-resolution and high-sensitivity
spectrum over the entire wavelength range from 300 to 2500 nm. We estimate the
mass accretion rates M_acc of the targets from 13 different spectral
diagnostics using empiric calibrations derived previously for T Tauri-type
stars and brown dwarfs. We have estimated the mass accretion rates of our
targets, which range from 2x10^-9 to 2x10^-7 M_sun/yr. Furthermore, we have
found accretion rate variability with amplitudes of 0.10-0.40 dex taking place
on time scales from one day to tens of days. Additional future night-to-night
observations need to be carried out to investigate the character of M_acc
variability in details. Our study shows that the majority of the calibrational
relations can be applied to Herbig Ae/Be stars, but several of them need to be
re-calibrated on the basis of new spectral data for a larger number of Herbig
Ae/Be stars.
