Pink-eye

Infectious Keratoconjunctivitis, commonly known as Pinkeye, is primarily caused by the bacterium Moraxella bovis. This condition can affect cattle of any age, leading to significant pain and distress, which in turn can result in reduced weight gain in younger animals and weight loss in adults.

​

Risk Factors and Transmission Pinkeye is most prevalent during the summer months. Several factors increase the risk of infection, including:

  • Dust

  • Stalky pasture

  • Pollens

The disease is transmitted through direct contact, such as when cattle rub heads in feed bins, or via flies that feed on the ocular discharge from infected animals.

​

Treatment Options Treatment for Pinkeye typically involves:

  • Topical Antibiotic Ointments: Applied directly to the eye to combat the bacterial infection.

  • Pain Relief: Administered based on the severity of the disease.

  • Surgical Intervention: In severe cases, surgical procedures may be necessary.​

​​​​

Prevention Strategies Preventing Pinkeye is crucial, especially for farms and areas prone to severe outbreaks. Key prevention methods include:

  • Vaccination: The most effective preventive measure, which should be administered six weeks prior to the anticipated Pinkeye season.

  • Stock Management: Ensuring proper handling and reducing stress among cattle.

  • Fly Control: Implementing measures to reduce fly populations that can spread the disease.

  • Grazing Management: Maintaining pasture conditions to minimize exposure to dust and stalky vegetation.
