Overview Quartermaster® Suspension (Penicillin Dihydrostreptomycin) is for intramammary use to reduce the frequency of existing infection and to prevent new infections with Staphylococcus aureus in dry cows.

  • Active against existing infections
  • Prophylactic against new infections, during the time when cattle are likely to become infected
  • Remains in the udder for a sufficiently long period to accomplish the intended objective and is not diluted with milk, as is the case in lactation therapy
