Bovine Ulcerative Mammillitis Virus, also known as BUMV, is a highly contagious disease that affects cows' udders. This viral infection causes painful sores and lesions on the teats, leading to decreased milk production and potential economic loss for farmers. While BUMV is the commonly used scientific term, there are few synonyms to refer to this viral condition. Some alternative names include Bovine Mammillitis, Cow Ulcerative Virus, and Teat Ulceration Disease. Regardless of the name used, it is crucial for farmers and veterinarians to quickly identify and manage this disease to prevent its spread within the herd and protect the overall health and productivity of the cattle.
