What are the different types of cow horns and how do they vary in size and shape?

There are two main types of cow horns: twisted horns and straight horns. Twisted horns are curved and spiral-shaped, while straight horns are, well, straight. The size and shape of cow horns can vary depending on the breed of cow. Some cows have long, wide horns, while others have shorter, narrower horns. Overall, the size and shape of cow horns are determined by genetics and can vary greatly between individual cows.
