The role of antibiotic dry cow therapy (aDCT)

Cannula insertion

Antibiotic dry cow therapy (aDCT) has a dual purpose:

  • Curing the existing subclinical infection at dry off
  • Preventing new infections before calving

The use of dry cow therapy has been a cornerstone of the 5-point plan for mastitis management for more than 30 years and has resulted in a decrease of contagious mastitis pathogens in many well-managed herds.
