Why do cows get scabs on their teats?

There are a number of reasons why cows may get scabs on their teats. Some of the most common reasons include:

* Mastitis: Mastitis is a bacterial infection that can affect one or more quarters of the udder. It is often caused by bacteria that enter the udder through the teat canal. Symptoms of mastitis can include swollen and tender mammary, changes in milk color, scabs or cracks in the teats.

* Chapping: Chapping is a condition that occurs when the skin on the teats becomes dry and cracked. This can be caused by exposure to cold weather, wind, or sun, as well as by excessive milking or rough handling.

* Teat injuries: Teat injuries can be caused by a variety of factors, such as snags on fences or equipment, bites from insects, or injuries from other cows.

* Vitamin deficiencies: Cows that do not receive a sufficient amount of certain essential vitamins, such as vitamin A and vitamin E, may develop dry, scaly skin, including on the teats.

* Infectious Bovine Keratoconjunctivitis (IBK): IBK is a contagious disease that affects cattle, causing eye inflammation and swelling, and can also lead to scabs or crusty lesions on the eyelids and teats.
