Description

The aim of this work was to evaluate somatic cell count (SCC) and Californian mastitis test (CMT) reliability as methods to survey mastitis in Serrana goats. Microbiological diagnosis, SCC and CTM were performed on 2028 samples, collected from individual glands during a lactation period. According to results CMT (predictive negative value = 69.5%) may be used as a cheap and practical method for sub clinical mastitis survey in Serrana goats. Decision on SCC use will depend on additional research works, since its values were very high even for bacteriological negative samples.
