    Mastitis is a complex disease, the product of several factors associated with both the interaction of the host with the environment and with the pathogenic bacteria present in the environment where dairy cows develop, negatively impacting the health of the animal with the consequent decrease in the production. To detect this disease, the California Mastitis Test (CMT) is applied, which is a sensitive and easy-to-handle test that is applied to each breast quarter. However, it can give false positives, so the interpretation of results could vary, for such reasons. reasons In the present study, the evaluation of the effectiveness of the CMT diagnostic test for the early detection and monitoring of bovine mastitis was carried out in the milk collection center in the Tahualag community. To develop this research, we had a population of 70 crossbred Holstein cows. When the prevalence of mastitis was calculated, it was established that only 18.6% of the females were positive, the predominance of which occurred in the left posterior quarter (CPI) with 31%, followed by 23% belonging to the CAI (left anterior quarter), the CAD (right anterior quarter) and the CDP (right posterior quarter). The calculation of the prevalence of mastitis according to age showed that there is greater influence in females 6 years of age (38.5%) and with less influence ages 7 and 8 years (7.7%). Among the biological agents causing mastitis, Staphylococcus aureus was identified in the highest percentage (38.5%), followed by 23.1% belonging to both Staphylococcus spp and Staphylococcus coagulase, and finally both Streptococcus dysgalactiae and Streptococcus uberis, each with the 7.7%.
