As cattle herds move to pasture, preventing pinkeye becomes essential. Pinkeye is a common issue that affects the eyes of cattle, causing pain and potential vision problems. Unlike other diseases, vaccines for pinkeye are not always effective because the condition involves multiple bacteria and risk factors.
Prevention is the best defence. A healthy cornea protects the eye from bacteria. However, irritants like UV rays, seedheads, and dust can damage the cornea and increase the risk of infection. Fly control is also important, as flies spread pinkeye from one animal to another.
Since flies can move between farms, all farmers need to take action. Using multiple methods, such as insecticide tags, sprays, and natural traps, can help reduce fly numbers.
Proper nutrition supports immunity. A good balance of nutrients and minerals helps the herd resist infections. While mineral supplements can be expensive, testing feed and water can help manage costs while maintaining health.
Early intervention helps avoid severe cases. Regularly check cattle for early signs of pinkeye. Start treatment immediately if symptoms are seen. Use antibiotics specifically labeled for pinkeye, and follow dosage and injection guidelines.
Other helpful treatments include:
- Eye patches to protect from light and promote healing
- Shading areas to reduce discomfort
- Anti-inflammatory medications for pain
- Topical sprays or ointments for support
While some extra treatments may have mixed results, they can be useful when combined with antibiotics.
“As with all health challenges, work closely with your veterinarian to develop a plan for dealing with cases,” said Chris Clark, beef specialist with Iowa State University Extension and Outreach.
By focusing on prevention and early treatment, farmers can reduce the impact of pinkeye and protect the well-being of their cattle throughout the grazing season.
