5 most common pathologies of cows:

• Clostridial Disease, or "Blackleg": Blackleg is an acute, febrile, highly fatal disease of cattle and sheep caused byClostridium chauvoei and characterized by emphysematous swelling, commonly affecting heavy muscles (clostridial myositis). It is found worldwide.

• BRSV (Bovine Respiratory Syncytial Virus): Bovine respiratory syncytial virus (BRSV) is a major cause ofrespiratory disease in cattle worldwide. Calves are particularly affected, even with low to moderate levels of BRSV-specific maternally derived antibodies (MDA).

• BVD (Bovine Viral Diarrhea): Bovine viral diarrhea is a viral disease of cattle and other ruminants that is caused by the bovine viral diarrhea virus (BVDV).

• Haemophilus Somnus: Haemophilus somnus has long been associated with thrombotic meningoencephalomyelitis but has also been identified as the agent responsible for other clinical diseases including respiratory disease, reproductive problems, myocarditis, otitis, conjunctivitis, mastitis, and polyarthritis.
