To investigate the sensitivity of repeat tuberculin test with bovine PPD, seibert's fraction A(SFA) and avian PPD tuberculins in visible and non-visible lesion reactor cattle to HCSM tuberculin. The comparative test, under the condition of this experiment, was entirely unsatisfactory to differentiate between visible and non-visible lesion cases, the high frequency distribution of the skin fold thickness greater than 10mm to SFA tuberculin appeared in visible lesion cases, whereas the skin reaction 1 less than 4mm to the SFA tuberculin appeared in NVL cases
