Fran I don't know the answer but don't feel ignorant. I don't quite understand this either. I have a 12 yr. old cow that I need to have tested so her offspring will qualify. And I do not really know how it all works. I am sure someone on here will clarify this for us....

The genetic marker report has a list of 16 (on a report from UCD) genetic markers like BM1818 or TGLA122, usually with a pair if numbers next to each like143/151. I asked the lab at A&M once and was told it doesn't mean anything interpretable to us, but just identifies your animal for those particular markers that they use for everyone. I can't find the printed UCD report for Siobhan right now, but on her A&M report she has 143 for TGLA122 so that means Macree got that one from her and the 151 from her sire.
The parentage analysis is a confirmation that, in this case, Macree "qualifies as an offspring of ZH Zephyrhill Siobhan and FF Lil' Christmas Cash." You won't always have both sire and dam parentage verified, but I like to do it if possible. If I understand it correctly, the genetic marker report is what they use to confirm parentage. Hope this helps. Maybe someone can explain it more clearly or fully.

Hi Fran,
The genetic marker report is used to parent verify your calf. You can only parent verify if the genetic markers of the sire and/or dam are on file at UC Davis. If both the sire and/or the dam's markers are on file at UC Davis, then you can choose Parent Verification. The parent verification will automatically generate markers (from the hair samples submitted) for the new calf to compare to the markers of the sire and/or dam already on file.
When you say transfer stuff, do you mean markers?? On the "cattle test" tab, in the upper left corner there is a heading "Cattle Foreign Type Form." This form will allow you to input genetic markers from another lab and create a case number at UC Davis, which in turn will allow you to parent verify. Clear as mud??
Hope this is helpful. :-)

Eileen, what if you have an older cow that is not DNA tested in the data base, like my Hazel? Where do you start so that her calves in the future can be Sire and Dam parent verified. I thought that it was now required that both parents be verified? Thanks Holly

Holly you have to have the parents tested, or transferred to the lab you wish to use. If you have genotypes at Texas and wish to use Davis, you can do the foreign transfer and enter the numbers yourself into the Davis form online, then scan the Texas genotype report and transmit it to Davis. If you don't have a genotype, just have it done at the lab you intend to use in the future for your calves and then request parent verify when you are having the calves tested and/or PV. In our case, most all of our cows are genotyped but their parents were not, so they are not parent verified, but all of their calves are/will be because we've genotyped all the cows/bulls. It still isn't required to genotype females to register them, but Fran has to do it due to the question of parentage of her recent calves. Actually she really only needs to test one of the questionable cows, and one of the calves to confirm parentage. The other two could be determined if they matched, or if they didn't match.

Hey Holly,
For Hazel you need to submit hairs and request a Genetic Marker Report. Once you have her markers on file then you will be able to request parent verification for her offspring. Basically, UC Davis compares the markers of the parents to the markers of the offspring. If certain markers match, they are able to verify parentage. As of now, the ADCA does not require any parent verification for heifers to be registered. For a bull to be registered you must verify his sire only. I think it will only help the breed and the integrity of the registry if we parent verify as much as possible. It has taken me about six months, but I finally have all of my herd's markers on file at UC Davis and am now able to verify all offspring. Whew!

Thanks so much Lakeport and Eileen. It is my intention to have everyone done, cows and bulls. I want to do it now while I only have a few. Thanks again for clarifying that for me.

Good info here, I am going to switch my test results over to UC Davis. I wish I would have read this post before I sent them to Texas A&M.
