Abstract: Three hundred and sixty-nine milk samples from half udders of 188 Murciano-Granadina goats in the second and third month of lactation, from ten commercial dairy goat herds were studied. Bacteriological analyses, California Mastitis Test (CMT) and somatic cell count (SCO by Fossomatic Counter were performed. The best SCC threshold for defining subclinical mastitis was 500 × 103 cells ml−1, but this threshold had a poor positive predictive value (28.5%) and only 62.3% of samples were correctly classified. Arithmetical and geometrical means of SCC showed statistical differences between infected and uninfected glands. Arithmetical and geometrical means of SCC per microlitre for each CMT score were, respectively: 312 × 103 and 172 × 103 for Score 0 and traces; 1014 × 103 and 531 × 103 for Score 1; 2912 × 103 and 2051 × 103 for Score 2; and 4950 × 103 and 4436 × 103 for Score 3. The CMT Scores 2 and 3 discriminated between infected and uninfected udder glands. The results show that both tests could be used in the period of study to detect a high percentage of true uninfected glands but the percentage of false positives was high. |
