Genetic defects test for Shorthorn

Guys,

How I can test my animals for TH and PHA?
As I live in Brasil, I'm able to send samples for north american labs?

You should be able to do it no problem as now you can send in tail hairs samples.

Thanks FRostback. To where I can send...where is the best lab?

If you google TH TESTING, it should give you the options. I just used http://www.agrigenomics-inc.com/forms.html , just print off the forms. Pull, not cut,  hair from the tail switch of the animal you want tested, you need the bulb at the end,  they say the animal should be over 4 months for hair to work, where gloves, if you touch the bulbs it can mess with the test. Put the hairs in a envelope, seal it. If you have more then one to test make sure you don't get stray hairs mixed up and use a new envelope for each sample. You will have to get a US currency money order to send with the samples.

Thank you again. Procede similar to paternity DNA tests.
OK, will look for it. Will see on link suggested as well.
My first option would be credit card payment, so will need to look for a lab that can accept CC.
By the way thank you very much.

CSI, please PM me the information when you get it, I have a TH carrier bull's semen I have never used because I don't want to bring TH into my pedigree herd.

I bought the semen after a visit to Ireland, heard about TH after it had been dispatched to me, and have only used it on commercial cows since I found out his status.

His calves have been excellent and their feedlot growth was excellent.

I sold them all to a feedlot that gave me feedback on growth and would therefore like to bring his clean progeny into my herd as they would be beneficial in the long term.
