What is freemartinism and how is it caused?

Freemartinism is when a heifer has male sex characteristics but has underdeveloped female sex organs. It is caused by sharing a placenta with a twin bull calf. The male sex hormones that is emitted by the male fetus as he develops in the womb inhibits the female's sex hormones, and consequently prohibits her from developing normal female reproductive organs. She retains the testosterone and develops bull-like characteristics after birth and as she gets older. Freemartins are sterile, so they're better off being raised for the freezer.

Can you breed a heifer if she was twin to a bull?

There's a 5 to 10% chance that you can. The rest of the time she'll be a freemartin and too sterile to be deemed usable to breed. She'd be better off being raised for the freezer than for a momma. You should get the heifer tested for freemartinism before you attempt to get her bred. Your large animal veterinarian will either do it for you or give you tips on how it can be done.
