    Description

    We evaluated a technique for measuring body fat content of marten (Martes americana) by using a noninvasive bioelectrical-impedance device with four electrodes to introduce a current into the body. Instantaneous readings of resistance were significantly correlated with fat-free mass (determined from solvent extraction) of carcasses of 17 skinned (r = 0.83, P = 0.01) and 6 intact (r = 0.89, P = 0.03) marten. Estimates of percentage of body fat were not accurate among skinned animals but were accurate among unskinned animals. With further refinement, this technique may be useful because the device is noninjurious, easily used, quick,and portable.
