Treatment of Pinkeye in Cattle
Dr. W. Dee Whittier, Extension Veterinarian, Cattle, VA-MD Regional College of Veterinary Medicine, VA Tech
With the arrival of summer, pinkeye treatment is an issue many producers have to face. Appropriate, timely treatment will minimize losses from this disease that sometimes defies preventive steps.
Probably the most important aspect of pinkeye treatment is that it be given early. When an ulcer first forms all that will be seen from a distance is an uncomfortable eye with lots of tearing. Cattle tend to hold the affected eye closed. Treatment at this phase before the eye becomes cloudy and “blue” will give very encouraging results.
If, on the other hand, treatment is delayed until the eye becomes cloudy or even worse until the classic pink appears with a white or yellow glob in the center of the eye, results will be much less satisfactory.
The approved products to treat pinkeye include the long-acting tetracycline products (for example, LA-200®, Biomycin 200®, etc.) and now tulathromycin (trade name Draxxin®). These products should be delivered according to label directions in terms of dose and route. Slaughter withdrawal rules should be carefully considered when any antibiotic is used.
