Abstract: 

CMT is one of the most common diagnostic tests in detection of subclinical mastitis in dairy cows. In this test, there are four degrees: tract 1, 2 and 3. Grade 3 CMT is equivalent to about 4 to 8 million scc/ml in milk. The previous reports have determined that blood table especially WBC and Neutrophils are changed in clinical mastitis caused by Escherchia coli, and Streptococcus agalactiae, However, there was not such data for subclinical mastitis in the literature. In this study CMT was performed in 833 dairy cows belonged to 5 herds in the province suburb of Tehran. Milk samples were taken for culture from all quarters with grade 3 CMT and 115 blood samples were randomly taken from 94 cows with subclinical mastitis (grade 3 CMT) and 21 cows without any sign of disease and negative CMT. The results were statistically tested using ANOVA test. There were no significant correlation between subclinical mastitis and changes in WBC/Neutrophils.
