Stamm: Treating pink eye in beef cattle

Published 11:59 am Wednesday, June 21, 2017

If you have been in the beef cattle business very long, it is no secret pink eye can be one of the most challenging heath issues an operation can face, especially during the summer months.

Pink eye, scientifically known as infectious bovine keratoconjunctivitis, is a bacteria that attaches to the animal’s cornea and produces hair-like structures. After it is attached to the cornea, the bacteria releases a toxin that kills cells on the cornea and creates the ulcers that are commonly seen with this illness.

There is a combination of factors that can cause pink eye in livestock herds, which leads to multiple treatment methods and, more importantly, preventative steps.

Pink eye in beef cattle can be caused by a number of factors including UV light and sunlight, face flies, eye irritation and other microorganisms. Lack of pigment around the eye of some breeds of cattle cause UV light from the sun to inflame the eye and allows infection to set up, ultimately leading to pink eye.

Face flies are also a huge factor in causing and spreading pinkeye outbreaks in your herd. Face flies irritate the eye while feeding on secretions, after doing this, they very effectively transmit bacteria from cattle with pink eye to other cattle in your herd which leads to its rapid spread.

Any type of eye irritation can also lead to the cause of pink eye, including the irritation from tall grass and weeds, barber wire, thorns and dust. The biggest factor in this is tall weeds and grass from pastures. In order to prevent pink eye you have to consider these causes.

It has been said “an ounce of prevention is worth a pound of cure.” This could not be truer when dealing with pink eye in beef cattle. In order to prevent pink eye, you must carefully consider all of the causes of pinkeye.

It is important to maximize your herd’s immune status through a strong free choice mineral program to make them less susceptible to the pink eye bacteria. This, paired with a strong vaccination program, will do more for overall herd health than anything. It boosts prevention of not just pink eye, but a number of other sicknesses.

It is also very important to maintain a good pasture mowing program to ensure an irritant-free environment for your cattle’s eyes. Last but not least, try to prevent face flies as much as possible in your herd through the use of rubs, drenches, ear tags and minerals.

If you have cattle that become affected by pink eye, contact the Clark County Cooperative Extension Office for advice or your local vet for specific treatment options. Early detection is crucial for pinkeye treatment and prevention.
