(ceftiofur hydrochloride)
Sterile Suspension


Attack mastitis-causing pathogens in the dry period

SPECTRAMAST® DC (ceftiofur hydrochloride) Sterile Suspension provides the most broad-spectrum label to treat the most common bacterial pathogens found in dry cows on modern dairies, including: Staphylococcus aureus, Streptococcus dysgalactiae and Streptococcus uberis.

Use SPECTRAMAST DC on your operation to achieve:

  • Zero milk discard* so you can get them back in the milking string faster.
  • The shortest meat withdrawal, allowing you to maximize your management options.
  • Greater overall flexibility in milk and cattle management decisions.
  • Treatment of more major pathogens than other dry cow therapies.

SPECTRAMAST DC treats the mastitis-causing pathogens you face. Less than 10% of the leading mastitis-causing pathogens were resistant to SPECTRAMAST DC at mastitis pathogen breakpoints in a 2014 surveillance report.1

  • SPECTRAMAST DC is indicated for the treatment of subclinical mastitis in dairy cattle at the time of dry off associated with Staphylococcus aureus, Streptococcus dysgalactiae and Streptococcus uberis.

    Up to 50% of new udder infections occur during the dry period. A comprehensive dry cow program including SPECTRAMAST DC can help reduce new infections during the dry period by up to 30%.

  • Read the complete package insert before administering SPECTRAMAST DC. Infuse one (1) syringe into each affected quarter at the time of dry off.

    Treatment: Wash teats thoroughly with warm water containing a suitable dairy antiseptic. Dry teats thoroughly. Milk out udder completely. Using an alcohol pad provided, wipe off the end of the affected teat using a separate pad for each teat. Choose the desired insertion length (full or partial) and insert tip into teat canal; push plunger to dispense entire contents; massage the quarter to distribute the suspension into the milk cistern.

    Reinfection: After successful treatment, reinfection may occur unless good herd management, sanitation and mechanical safety measures are practiced. Cows should be watched carefully to detect recurrence of infection and possible spread to other animals.
