Mastitis and Dry Cows

by Carrie Bargren, DVM

At a price of $200 per cow per year, mastitis is the most costly infectious disease among dairy herds. Control strategies, good case identification and treatment protocols like those discussed last month have greatly reduced the prevalence of contagious pathogens during lactation.  But it is easy to forget how critical the dry period is in treating chronic infections and preventing new ones.  Continue reading
