Incidence of clinical mastitis in dairy herds grouped in three categories by bulk milk somatic cell counts.
Incidence of clinical mastitis was studied in 274 herds grouped in three categories by bulk milk somatic cell count (SCC). Mean incidence rate of clinical mastitis was 0.278, 0.257, and 0.252 casesExpand
