Any freemartin success?

Post by John in WI » Mon Mar 06, 2006 5:31 pm

I know that the fertility rate on freemartins is about 5%, but I'm wondering if anyone out there has had success in breeding one of these? I have a pair of twin holstiens - one bull, one heifer. She's very friendly and I'd love for her to be fertile, although I know the chances are slim. Just looking for anyone who's had success. Thanks.

By definition a freemartin is a sterile heifer. Not all heifers born twin to a bull arefreemartins. There is a DNA test through UC Davis that will tell you conclusively if she is or isn;t a freemartin

I have a friend who is a Simmental breeder. They had two different heifers born twin to a bull, that they successfully bred. If she looks normal on the outside, and you can slip a thermometer in her vulva, it's worth the blood test to check her out. Or you can wait til she's breeding age, and if she cycles, have a vet palpate her.

I've never had any luck with a twin female being able to breed. Last year took one to A & M to check, and the vet said in his experience, he's never seen one that is a breeder.

Do not waste your time.

There are a LOT of good animals out there - even some good - ughhhh - Holsteins.

Sell it - buy another. Any time spent on this heifer is time wasted and the delay of another calf.

If you are in it for the money you know I speak the truth and you know what to do.

If you are in it for ..... whatever .... then you will not do as I suggest anyways. Calf is an animal - dsigned to be used for food, milk, other calves or whatever. Not designed to be a pet. They grow big and they can grow to be trouble.

Fatten it and eat it if you do not want to sell it. Properly finished Holstein tastes rather good actually.
