The association between quarter somatic-cell counts and clinical mastitis in three British dairy herds

The association between quarter somatic-cell counts (QSCCs) of milk and the risk of clinical mastitis (CM) was investigated in a 1-year study on three dairy herds in Somerset, UK. The three herds had 95–130 milking cows and an annual mean bulk milk somatic-cell count (BMSCC) of 200×10 3 cells/ml has...

Description
Summary:The association between quarter somatic-cell counts (QSCCs) of milk and the risk of clinical mastitis (CM) was investigated in a 1-year study on three dairy herds in Somerset, UK. The three herds had 95–130 milking cows and an annual mean bulk milk somatic-cell count (BMSCC) of 200×10 3 cells/ml has over three time the odds (OR=3.7, P200×10 3 cells/ml were not significantly different from the baseline. Finally, when S. uberis CM were investigated, quarters with SCC >200×10 3 cells/ml had more than three times the odds of S. uberis CM compared with QSCC 1–20×10 3 cells/ml (OR=3.73, P
