When does the beefmaster cow have to be dehorned?

Beefmaster cows do not need to be dehorned. They are a naturally polled breed, meaning they are born without horns.

While some individuals within the breed might have horns, it is not a common occurrence and is usually due to genetics.

Therefore, you wouldn't need to dehorn a Beefmaster cow unless it was a rare case with a horned calf.
