Abstract: This study was conducted to determine the levels and relationship between Lacto Peroxidase (LP) activity and somatic cell count (SCC) for diagnosis subclinical mastitis in early lactation of dairy cows. Foremilk samples were obtained from quarters of 80 cows (August 2007 up to February 2008). Any cows had not evidence of clinical mastitis at time of sampling. The SCC ranged from 5.24�105 cells/mL in the first parity to 5.5�105 in the third parity with a mean value of 5.45�105. The mean LP activity in first, second and third parity were found 6.49, 4.63 U and 5.5 U mL 1, respectively. No significant correlation (r = 0, p>0.05) was found between number of SCC and LP values in early lactation. Since, the measurement of LP activity of milk may not be used as a predictor subclinical mastitis in the early lactation period of dairy cows.
