Testing is available but only to certain sources. All of the major bull studs have tested their ai sires. There is a list available throught the AAA on what bulls are carriers. The best way to go about this is that if you have any cattle with the genetics of the carrier bulls then they have a possibility of being a carrier. If your cattle do not have these genetics there is nothing to worry about. I have been told that there will be a test released to the public around the first of the year and will work basically as described above. I have also heard that pricing could be around $50/ head or greater, but that could be just talk. A few of the more important bulls that are carriers are future direction ( and his clones), as well as the Accelerated Genetics bull 2V1.
