A cow's ocular conjunctiva is covered by the eyelids. To examine the conjunctiva, there are generally two methods: first, press open the lower eyelid with your thumb to expose the conjunctiva. Second, grasp the cow's horns with both hands and forcefully turn the head to one side; the cow will then look sideways, exposing the conjunctiva. In a healthy cow, the ocular conjunctiva is pale pink. Redness of the conjunctiva is a sign of circulatory disturbance and may indicate eye trauma, conjunctivitis, or various acute febrile infectious diseases. A blue-purple conjunctiva may indicate pneumonia or heart failure

In a healthy cow, the ocular conjunctiva is pale pink.

Redness of the ocular conjunctiva is a sign of circulatory disturbance and may indicate eye trauma, conjunctivitis, or various acute febrile infectious diseases.

A blue-purple ocular conjunctiva may indicate pneumonia, heart failure, and some poisoning diseases. All of the above conditions can increase the content of reduced hemoglobin.

Yellowing of the ocular conjunctiva may indicate liver disease and certain poisoning diseases. This is because the above conditions can increase bilirubin in the blood, and increased bilirubin causes the ocular conjunctiva to appear yellow.

Hemorrhagic spots or hemorrhagic patches on the ocular conjunctiva are the result of increased permeability of the blood vessel walls, and these symptoms are manifestations of hemorrhagic diseases and bracken poisoning.
