Features and Benefits

Keep more of your hard-earned profits with ZACTRAN
ZACTRAN controls and treats BRD so cattle get on feed quickly and keep gaining weight.

  Reaches the site of infection in just 30 minutes3**
After you administer ZACTRAN, the broad-spectrum antibiotic rapidly reaches the site of infection — the pulmonary epithelial lining fluid (PELF) of the lungs — where it kills bacteria and stops them from replicating.
  With ZACTRAN, you typically see improvement within 24 hours*
Cattle treated with ZACTRAN in a study had lower temperatures, were more alert and were breathing easier within 24 hours.1
  The convenience of 10 days of therapy from a single injection2
ZACTRAN keeps working for 10 days, reducing the time and labor associated with repulls. With less animal handling, cattle experience less stress and setback so they can put more energy into gaining weight.
  Treat cattle with one cost-effective dose
ZACTRAN is competitively priced, and a single dose goes a long way, providing 10 days of BRD treatment or control. Use our
pricing calculator to compare costs with your current treatment.
