What is lumpy jaw in cows?

Lumpy jaw, scientifically known as Actinomycosis, is a bacterial infection caused by the bacterium Actinomyces bovis.

It primarily affects the jaw, leading to the formation of painful swellings and abscesses, particularly around the mandible (lower jaw) of cattle. This disease can result in significant problems for affected animals, including difficulty eating and weight loss.

What are the causes of lumpy jaw in cows?

Lumpy jaw is usually caused by the introduction of bacteria into the soft tissue of the jaw through injuries or abrasions. Common causes include rough feed that can cause cuts, dental issues, or injuries resulting from fights with other cattle. Once introduced, the bacteria can proliferate, leading to infection and the characteristic lumpy appearance of swollen jaws.
