摘要

Mastitis is considered to be the most costly disease for dairy cattle herds in the developed countries (Halasa et al., 2007). It is also a major cause of impaired animal welfare (Broom et al., 1991). In addition, the majority of antibiotics used in dairy herds are used to treat or prevent mastitis (cited from Gussmann et al., 2017). Although large efforts have been made to manage mastitis, it remains a major problem in dairy herds. This is driven by several factors including the increasing herd size(Jergensen et al., 2016), application of AMS milking systems (Hovinen and Pyorala, 2011), increased milk production and emergence/reemergence of new strains causing mastitis (Lyhs et al., 2016). Therefore, farmers should continuously be looking for improved management to control mastitis. Naturally, the cost-effectiveness of improved management should be taken into account.
