Bull nose is a condition in cattle and pigs characterized by facial swelling, sneezing, and nasal discharge. This condition is often caused by an injury to the nasal area, which then gets infected by the bacterium Fusobacterium necrophorum. The infection leads to inflammation and the formation of fluid-filled lumps, resulting in the noticeable symptoms. Treatment typically involves antibiotics to fight the infection and measures to manage pain and swelling. Preventive care, including maintaining good hygiene and minimizing nasal injuries, is crucial to avoid the occurrence of bull nose.
