Pinkeye Prevention and Control

Pinkeye (Infectious bovine keratoconjunctivitis) is one of the most common, highly infectious and costly problems facing your dairy and beef herd.

Controlling pinkeye in your dairy or beef herd is a difficult and continuous challenge. Pinkeye is a bacterial disease which causes infection, ulceration and inflammation of the eye. A pinkeye infection can cause discomfort and blindness to dairy and beef cattle resulting in animals going off feed, losing productivity, costly antibiotic treatments and withdrawal times after treatments.


  • Flies — The most common problem with pinkeye in dairy and beef herds. Flies feed in the eye area and easily spread the disease throughout a herd by carrying the infected eye fluid to other dairy and beef cattle.
  • Poor sanitation — Pinkeye is highly infectious and can easily be spread during treatments when not wearing gloves or using disinfectants.
  • Dusty environment

Prevention and Treatment

Prevention is key to minimizing economic loss from pinkeye infections and controlling pinkeye in your dairy or beef herd. For the most effective pinkeye prevention program, use vaccinations in conjunction with control methods.
