Is it 9 months gestation for cows?

Anywhere from 270 to 295 days. Depends on the cow, just like women.

For those of you that are exposing females to only 1 bull at a time, as in a registered herd, how many days do you count back from birth to get conception date? I currently take birth-date - 283 days, and then look at my records to see who the cow was exposed to at that time to determine the sire.

The reason I'm asking is because if you expose a female to multiple bulls throughout a time period, and counting back 283 days, the conception date is within a few days of the bull switchout date, it could be hard to determine the right bull, considering all the variables (cow exposed to bulls of same color, did cow deliver a few days early or late, etc).

I AI the majority of the registered herd, so I know the date of conception, there are a few though that are serviced naturally, these are kept in with the bull for at the least 40 to 60 days. I only expose to one bull a year, that way there is no question to who the sire is.

A DNA test is relatively cheap if you have a really good one that is close. If they are just for commercial use then it really does not matter if it is close. We have a few really good ones that we were not sure about so we had them DNA tested. We have been right on all but one but peace of mind is worth the few dollars is cost to do the test.

What does a DNA test cost? Do you have to take the animal to a special testing site, or can it be done by a vet, etc?
