The Curious Case of the Female Cow and Her Horns

Female Cow and Her Horns

Have you ever seen a cow in a field and wondered why some have horns and some don’t? Or why, if they do have horns, they’re always different sizes? And what’s with the whole “horned” or “polled” designation anyway? Today, we’re going to take a deep dive into the world of bovine horns to learn a little more about these impressive appendages.

Do All Cows Have Horns?

The short answer is no, not all cows have horns. In fact, it’s estimated that around 30% of cows worldwide are hornless. However, the vast majority of dairy cows in the United States are hornless. Why? Well, there are a few reasons.

First of all, horns can be dangerous—both for the cows and for the people handling them. They can get caught on things and cause injury, so many farmers opt to dehorn their cattle for safety reasons. Dairy cows also tend to be confined to smaller spaces than beef cows, so dehorning helps prevent them from injuring each other. Additionally, it’s much easier to milk a cow that doesn’t have horns getting in the way.

So, How Do Cows Grow Horns?

Horns are made of bone, keratin, and other proteins. They grow from bony cores that protrude from the forehead—one on each side of the head just above the eyes. Calves are born without these bony cores, but they typically start to grow within the first few weeks of life as cartilage is replaced by bone tissue. By around 6-12 months old, most cattle will have fully developed horns.

Are There Any Benefits to Having Horns?

Some people believe that horns contribute to better airflow around the head and help regulate body temperature—sort of like an innate cooling system. Others believe that they play a role in communication, helping cows signal their dominance or aggression to others in the herd. However, there isn’t any scientific evidence to support either of these claims. For most cattle, horns are simply a fact of life.
