While we are all glad that the warm summer weather is here and hopefully the rains will slow up a little, with that also comes pinkeye season. It seems that some herds almost never have problems with pinkeye, while others have a high incidence of it.
Pinkeye is most commonly found in calves due to their lower immunity to the bacteria. Irritants such as grass seed heads and dust, don’t cause pinkeye, but they do irritate and inflame the eyes allowing the bacteria to get a foothold. Flies are the biggest vector transmitting the bacteria from animal to animal.
Treatment of pinkeye can be challenging, however there are some basics cattlemen can do to reduce the chances of pinkeye setting in. See Dr. Doug Ensley’s paper on pinkeye to learn how to prevent and manage this common disease.
