Correct answer: B. Using post-milking teat disinfection
- A. Washing the animal after every feeding
- B. Using post-milking teat disinfection
- C. Increasing the amount of grain in the ration

Post-milking teat disinfection reduces the number of disease-causing organisms on the teat skin and helps protect the open teat canal. Grain feeding and water supply support production but do not directly control contagious mastitis.
