Why do some breeds of cattle have horns and others don't?

Polled cattle are a modern genetic variation in cattle. Cattle that have gone wild, generally don%26#039;t survive unless they have horns to protect themselves, but those same horns can cause a lot of damage to each other when closely confined.

Why do some breeds of cattle have horns and others don%26#039;t?
Why are some people tall and others short why do some people have red hair and some blonde??? It%26#039;s because of their genes. If the cow has horns and the bull doesnt then theres a 50% chance that the calf will have horns. It all has to do with dominant and recessive genes if theres one dominant gene then theres a 50% chance of it. If theres to recessive genes there also a 50%chance. Study more in biology or anatomy
Reply:Through selective breeding. hornless cattle are called polled. Some are dehorned to keep them from using them on other cattle at feeding time. By the way ,Both bulls and cows have horns if they are a horned breed.
Reply:In the begginging there were breeds that did not have horns at all and breeds that had horns because of genetics. Now that many breeds have been bred together there are several breeds that have horned or polled( no horns). Certain breeds allow a certain amount of another breed into an animal and they are still considered purebred. This is how many breeds became polled. Polled cattle are easier to handle and less dangerous without needing to be dehorned.





Also, bulls, cow, heifer, and steers can all have horns.
Reply:I think they all do.





Both male AND females grow horns, unlike deer, which grow antlers. Antlers fall off every year, horns do not.





Most people de-horn their cows, which, i believe involves putting some chemicals on the calves head so that horns do not grow.
Reply:lol superglue not as much as you - the asker knows not all have horns.





As said some are polled...there is a gene that prevents horn growth. It is most common in the angus breed - which DO NOT have horns. There are also polled Herefords, charolais, limousin etc. Many breeds have horns of various sizes, from relatively short horns to massive spreads of Longhorns and Watusi cattle - both are *bred* for lots of horn. Cow or bull does not matter - breed and breeding does.





Many people who have breeds that have horns remove the horns for the safety of people and other animals in the herd and so that they can get their heads in feeders and such that often horned cattle can%26#039;t. There are a few methods of removing horns...chemically (not used as much do the danger of the chemicals), cutting or disbudding. The latter uses a hot iron to burn/kill the horn when it barely starts to grow...this stops the growth of the horn if done properly. The other option is if horns are already growing to cut them off near the base of the head...much messier and more prone to infection and flies.
