Red eye disease in cows, that is, infectious conjunctival keratitis, is the most common eye disease in dairy cows. Most of them occur in the summer, and yak and young cattle within 2 years of age are frequent, with rapid infection and high incidence. The pathogen of the disease is Moraxella vaccae, and flies and certain moths are the main vectors of the disease. After the occurrence of pink eye disease in dairy cows, it should be immediately isolated to a dry, dark barn treatment, and environmental disinfection and fly killing work should be done.
Treatment measures:
1. Apply the gentamicin, penicillin, and tetracycline ointment to the affected area 1-2 times a day.
2. Apply the affected part with atropine ointment 1-2 times a day.
3. When the conjunctivitis is obvious, 50,000 units of gentamicin or 300,000 units of penicillin G are injected subconjunctivally, once a day.
4. Intramuscular injection of tetracycline 20 mg per kg body weight, once every 3 days. If the corneal cloud is left after treatment, the topical Chinese medicine will be removed. In summer, the red eye disease of dairy cows is mostly endemic. After the diseased cattle are found, the cattle house should be widely disinfected. Some commonly used disinfectants can be used.
2D Cryovials are made of transparent polymer polypropylene, which is made by a special process to withstand low temperatures and ensure no leakage. It is suitable for long-term low-temperature storage of cells and tissues. The frozen storage tube is generally used for low-temperature storage of laboratory cells. For storage and preservation of tissue cultures and biological samples,
