To investigate the relation between non-invasive bioelectrical impedance values and Beef Marbling Standard (BMS) numbers measured from the surface of the sirloin part in live fattening cattle within one month before slaughter, the extracellular resistance (Rex), intracellular resistance (Rin), and the cellular membrane capacitance (Cm) were calculated using the measurement values in bioelectrical impedance analysis (BIA). The non-invasive BIA approach showed lower estimation capability than the invasive BIA approach. However, significant correlation was found among Rin and BMS values. This result indicates that non-invasive BIA might be useful to estimate the BMS number in live fattening cattle. Further development of this measurement technique is necessary.
