    The aim of this study was to identify the loss of antiseptic effect of copper sulfate (CuSO4) if associated with thenumber of cow passing in footbath. A total of 360 Holstein and Simmental cows were milked three times daily in 2x12herringbone milking parlor. After 360 cows passing from footbath (220x90x15 cm) containing 0%, 2% and 4% CuSO4, thesample was collected for pH and microbiology. The loss of antiseptic effectiveness was considered when pH more than 5. Themean pH at the end of 15 passages of cows was 8.13, 5.00, and 4.20 for 0%, 2% and 4% CuSO4 solutions. pH was greater than5.0 after 7 passages of 24-cows in 2% CuSO4 concentration and did not exceed 5 even after 15 passages in 4% CuSO4concentration. Change in color was correlated with pH. Samples were incubated for 24-72 hours for bacterial and fungalgrowth. E.coli was present at control group of CuSO4 concentrations, whereas fungus was not present. In conclusion,increasing pH due to the number of cow passing indicated the effectiveness of CuSO4 in footbath was lost. Antiseptic effectin 2% CuSO4 solution was lost after 168 cows passing through footbath, whereas antiseptic effect in 4% CuSO4 solution lostafter 360 cows passing through footbath.
