Mastitis research update from the University of Nottingham Dairy Herd Health Group

Undergraduate student working at the dairy centre.

In the UK, the average dairy herd size is currently ~133 cows and the incidence rate of clinical mastitis (CM) is likely to be somewhere between 47 and 65 cases/100 cows/year. The national average bulk milk somatic cell count (BMSCC) is currently ~167,000 cells/ml and this number has been falling steadily since 2009. Clinical mastitis in the UK is caused predominantly by pathogens traditionally classified as ‘environmental’, with Strep. uberis and E. coli being the most commonly diagnosed pathogens. In contrast, pathogens traditionally classified as ‘contagious’ now account for only around 10% of diagnoses made.
