ABSTRACT
Mastitis is an infection of mammary glands caused by microorganisms, which affects the dairy cattle worldwide. Subclinical mastitis are asymptomatic, but with decrease in production. Diagnosis is made through somatic cell count (SCC) in milk, and the greater the amount of these cells, the greater the productivity loss from the animal. In this research we tested the applicability of on-farm testing methodologies for the rapid diagnosis of Subclinical Mastitis, by the use of the California Mastitis Test (CMT) and a modified Wisconsin Mastitis Test (Somaticell®) at the time to perform manual milking. Forty five 45 lactating cows, belonging to three family dairy farms located at the following Regions of Rio de Janeiro State, Brazil Coastal Lowlands; Metropolitan; and Northwest, were analyzed. From 177 mammary quarters tested, 73 (41.2%) presented positive result at CMT (Figure 1), and 82 (46.3%) positive result at Somaticell® (Figure 2). There was a variation of 5.1% between one test and the other; 17 teats (7 animals) presented positive result at Somaticell® and negative at CMT, while 8 teats (2 animals) presented positive result at CMT and negative at Somaticell®. Three cows had already lost one mammary quarter. Both tests have a visual reading, although CMT is a qualitative test with subjective reading of positivity negative (-), positive (+, ++, +++ e ++++), and Somaticell® h
