Twins from different bulls

kfk

Cow had twins last night. One was a FR bull and the other was an AAX bull. First time I have come across this! Anyone here ever seen twins from two different bulls?

Rubbish..... there colouring may suggest their different breeds but there the same.... Maybe you should read up a bit on the birds and the bees

Adne,
I think it is you that might have to read up on the birds and the bees:D

If the fertilised egg splits in two, then identical twins.
If the cow releases two eggs together then twins from different sires is possible.

I'd imagine it is very rare though.

Well if possible with a woman then I guess it is possible with a cow. I have a vet calling in an hour or two so I might mention it.

We had a Simmental-x cow years ago have an Aberdeen Angus bull calf and a Charolais heifer calf in the same twin birth. They were very identifiable as the two different breeds.
We had changed her group between the two bulls at or around the calculated conception time, so she could most certainly have been tipped by both during the same heat.
According to my recollection of Leaving Cert/Gurteen biology and as confirmed by our vet at the time, it's most certainly possible, as described earlier when multiple eggs are released.

I take back my earlier comment..... you learn something new every day

I had a cow a few years ago that had a friesian calf and AA calf. After she had the first calf I checked her as she seemed to be carrying a second calf which she was. The first calf was born live and was fully developed the second calf was a month premature but was alive. She was inseminated with a friesian bull and I also had an Angus bull with the cows.

I'd say Ford4000 was talking about the age difference between the twins, rather than their different sires.
That was something I remember we were told was technically possible but happened very rarely; this is certainly the first time I've heard of an example in the real world.

poor farmer

seen it often with sheep
