Here's why:
* Hooves are made of keratin: Hooves are made of a tough, fibrous protein called keratin, similar to human fingernails and hair. Keratin doesn't regenerate in the same way as living tissue.
* No living tissue: The hoof itself is dead tissue. The living part of the hoof is the "corium," a layer of sensitive tissue beneath the hoof wall.
* Treatment: A broken hoof on a baby calf will need veterinary attention. Treatment might involve bandaging, casting, or even hoof trimming to help the hoof heal properly.
Important Note: If you see a baby calf with a broken hoof, it's crucial to contact a veterinarian immediately. They can assess the injury and provide appropriate treatment.
