Pink Eye

Pinkeye strikes when environmental conditions are right - strong, sunlight, combined with anything that can irritate the eye, especially dry, windy conditions, and mature, stalky vegetation.  These conditions peak in Spring and Summer.

Vaccination works well
Piliguard Pinkeye Trivalent is a single shot vaccine.  It works by helping to develop and maintain immunity by generating antibodies against M.Bovis in the animal's blood and tears.  This helps prevent the bacteria attaching to the eye.

Vaccinate dairy beef calves on arrival.  The best time to vaccinate is three to six weeks before the onset of the pinkeye season, usually late Spring to early Summer.  However on dairy beef rearing properties we have found that the vaccine works best when given as the calves arrive on farm, before they mix with other calves.
Quarantine and treat all clinical
The vaccine may not always provide 100% protection.  It is important to treat and quarantine all clinical cases promptly to reduce the level of challenge.  Outbreaks can be treated with antibiotics and where the cornea has ulcerated, we can surgically construct a flap over the ulcer to protect it and hasten healing.  It is also important to provide good nutrition and worm control to underpin protection, because undernourished animals are more susceptible.
Consult our vets
Both the vaccine and the antibiotics used in treatment are prescription animal remedies.  As farm systems and animal health requirements vary please contact one of our veterinarians if you would like to discuss a management programme for the prevention of pinkeye in your cattle.
