The objectives of this study were to describe Clinical Mastitis (CM) risk factors, determinate the prevalence of CM and Sub Clinical Mastitis (SCM), and estimate the cost of CM in dairy cows over UNALM’s two stations. The historical data of CM cases was collected and the prevalence of SCM was evaluated by CMT and SSC test. In addition, samples of milk were taken in order to determinate the microorganisms involved, and the effect of common antibiotics against them. The results showed that the average monthly prevalence for both, “Labrador” and UEZ stations were 2.72% and 6.09%. Labrador station showed a higher prevalence of CM over high production cows, while UEZ low production cows. According the number of births, both showed a higher prevalence over youngest cows. The ANOVA test by fitting each year as a one way experiment factor, showed that in 2013, both stations presented the lowest prevalence of CM, with no significant differences between the others years. The prevalence of SCM found for both, “Labrador” and UEZ stations were <49.32 – 70.67 %> and <88.44 – 97.26 %>. The average of somatic cells for each millilitre of milk was 1 254 for “Labrador” and 873 for UEZ. Overall the cost associated to each CM incident were S/ 394.57 (Labrador) and S /481.76 (UEZ)
