Are there any ways to tell if your heifer is a freemartin by her outward appreance? I have no background info about my heifer because she was donated to me from a local dairy. I've heard that a large tuft of hair on her vulva can mean she is a freemartin.She has a large white tuft and her belly is pretty big compared to others of her breed that i've seen. Is this a sure way sign to know or is there a test that will show for sure if so is it worth testing her. I was hoping to raise her as a breeder but if shes not going to reproduce then i'll sell her now. Any info will help thanks.
