Freemartins are a relatively rare occurrence, affecting only about 1 in 1000 cattle births. They are often mistaken for bulls or steers because they have a more masculine appearance than cows. However, they are not able to breed and are therefore of no value to the cattle industry.
Freemartins are sometimes raised for beef, but they are not as valuable as cows because they produce less milk. They are also more likely to have health problems than cows.
In some cultures, freemartins are considered to be good luck. They are also sometimes used in religious ceremonies.
Despite their rarity, freemartins are an important part of the cattle industry. They are a reminder of the complex biology of reproduction and the role that hormones play in development.
