The dairy farming activity is important in Brazilian agribusiness, which generate food and income for the population, its growth has occurred through intensification of production systems and genetical improvement, aiming higher profits and lower costs, however this production increase also raised the risk of metabolic disorders. The aim of this study was to correlate subclinical hypocalcemia boards and ketosis with mastitis in crossbred dairy cows in Caparaó region, state of Espírito Santo. Crossbred cows were used (Holstein x Zebu) at different production phases coming from 34 properties in seven counties of the Caparaó Capixaba region. It was carried out the diagnosis of clinical and subclinical mastitis through the tests for black background Mug and California Mastitis Test (CMT) respectively. The blood sample was collected by puncture of the vein or artery coccyx in vacuum tubes without anticoagulant, the dosage of glucose was performed using total blood in a portable glucometer Optium Xceed®. Serum concentrations of ß-hydroxybutyrate (ßHB), non-esterified fatty acids (NEFA), triglycerides, cholesterol and calcium were performed in automatic biochemical analyzer. Statistical analyzes were performed using the Statistical Analysis System (SAS) version 8.0 and OpenEpi program. There was high incidence of clinical mastitis (4.85%), subclinical mastitis (44.50%), subclinical ketosis (34.20%) and subclinical hypocalcemia (29.89%) in the micro Caparaó Capixaba. No correlation was found between bovine ketosis and mastitis, however hypocalcemia in increased 2.72 times as likely to suffer cows with mastitis frames
