Someone told me of this happening but i am pretty skeptical about it:

Cow gets bred on Cycle 1. 21+/- days later on Cycle 2 cow gets bred again. 9 months later Cow has a calf. 21 +/- days later, she has another calf. Breeder was told that cow was bred twice and had the calves from getting bred on 2 different cycles, and they are not twins born 3 weeks apart.

I do not really see how this is possible. Has anyone seen this before?

I assumed they were either twins born a few weeks apart, or the cow stole another cow's calf.

What do yall think?

Yes have heard of this happening, pregnancies in each horn at different times. And why aren't they twins, or at least half-twins they have the same dam?

Is your cow blue?

Interesting. I am surprised that could happen. I wonder if the cow not recognizing the first pregnancy could lead to more feritility problems?

I'm not trying to steer this post in another direction but, how well would the second calf fair since the cow would already be milking and I assume (Ya I know what happens when I do this) that there isn't any colostrum for the second one?

As in all thing's in life,yes it is possible for this to happen.It is the exception, and not the rule.

I don't know if Jack Co. is ready for blue cattle or not.

Great questions. These are some of the questions I was wondering about if this really did happen.

It seems to me there would be, or could be, many negative side effects of having multiple offspring in a manner like this. I am not sure how comfortable I would be keeping her and her offspring in my herd.

Here is a link to a study that was done on something similar to this at LSU

http://etd02.lnx390.lsu.edu/docs/availa ... 02-222405/

I have never witnessed cattle doing this. I have never met anyone who has witnessed this. Based upon the study on the link above, I guess it is possible for a cow to be bred after she becomes pregnant, but it does not appear that she will have calves at different times.

When the cow goes into labor, how does she only give birth to one calf?

Sorry guys and gals, but I think this one is BS. Can't happen. I'd have to see it to believe it.

That is a great point. With that amount of force wouldn't the labor flush out all foreign objects?

I am still having a tough time believing this could happen. Maybe I need to see it to believe?

Cows have two horns, they can get pregnant in either one. If they do have calves developing in each horn labor is not necessarily going to expell the calf in the other horn.

but if they were only 30 +/- days apart, wouldn't both be in the uterus at the time of the first birth?

my first thought was a hormonal problem. Because at day 15 or 16 post fertilization the developing embryo (blastocyst) will produce bovine-Interferon tau (bIFN-t) which should allow the female to recognize she is pregnant. By getting fertilized twice in two consecutive cycles this should indicate a hormonal problem. However, I do know there always some exceptions to the rule, and I was interested what everyone else thought or knew about this.

Thanks for all the replies, and keep em comin.
