Mastitis (inflammation of the mammary gland commonly associated with bacterial infection) is a highly prevalent and costly disease for the dairy industry. The epidemiology of mastitis, milking techniques, and diagnostic and control methodologies differ in New Zealand compared with overseas production systems, due to the milking of large herds with low labour inputs per cow in a predominantly pasture-based, seasonal-calving management system (Woolford 1986). The high prevalence of Strptococcus uberis in dairy cows in New Zealand has focused research on this pathogen. This review highlights the contributions of New Zealand researchers in understanding the epidemiology, bacteriology and control of mastitis that occurs in New Zealand dairy herds.
