PHA status 2 x Hiyu Cows

[tonhou]

I have a bull in NZ who has in his GGParents line Hiyu Renown Rosegay VII and Hiyu Rosegay V. I am thinking of getting him PHA tested but wondering if anyone knows the PHA status of these 2 cows. I think they are both suspect as any mention of them online says nothing of PHA and also Rosegay V was sired by Giacoma who I believe is considered to be a carrier, and Renown Rosegay VII has dam Rosegay who is a carrier!

Thanks if anyone knows anything that might save a test.

Hi...Carol Davidson (hiyu) here:

I owned Priapus for three years and used a son (Giacomo) for quite a while in my herd. As soon as the pha info was made public in AU, and we learned Priapus was a carrier, I immediately listed every Dexter exported to New Zealand (my own and others that had any Woodmagic in their bloodlines--Pat Leek imported some from AU), and noted the generational connection. The list was sent to the NZ Society. I know pha was mentioned in Council, and something was put in the Dispatch. I don't know what happened in NZ after that.

I don't know if USyd at Camden is still offering the test. DCAI can tell you that. They were taking hair. Or, you could send hair (with a vector import permit) to SRC in Canada, or UCal Davis or Texas A&M in America. All labs use the same test.

You could contact NZ owners of previous generations and see if they've tested. Or you could test your bull and have the answer directly. By the time pha was known about, I had very few animals left. I tested those with Priapus connections, and one tested positive: the original Rosegay (still here at 20. You can view her here on this Board on the Photo Album heading, Dexter Udders thread). All her testable offspring have come back negative, including all sons on AI. I did contact anyone I could reach who'd purchased from me, and notified them of the issue. I don't know what steps they took.

Cheers, c.

Thanks for the responses. The options for PHA tests for NZ breeders are to send tail hairs to Au or USA - test cost 50 Au dollars to go to University of Queensland, 25 US dollars to UC Davis Veterinary Genetics Laboratory, California.
I believe pha testing has seldom been done here but just recently a couple of cases have been brought to our attention, so people are thinking about the need to check bulls.
It has also been complicated by the local mail carrier (NZ Post) saying that tail hairs are on their restricted list (classed as "fur & skins) and they would not carry them. However I did send some to Au (for BD tests) recently and they did get through.
It would be great if we had some local test facilities.
Thanks Carol. Yes I did see the thread on udders and the grand age and enduring quality of Rosegay.

We send tail hair to NZ for A2 testing often, no problems, just a current biological products permit form inside, and the biologicals permit number written on the outside of the envelope.

Sorry, my point is I can't see why similar documentation can't facilitate easy international PHA testing.

Thanks genebo, that looked really promising until as I went through filling out the form I found you had to live in US or Canada.
I think it is relatively straight forward to go through UC Davis directly from outside US, though I haven't been through the process yet - hopefully some of those combination discounted options exist that you mention.

Thanks for finding that out. I still seem to run into snags using the preset form page that you have linked to above. It cannot cope unless all blocks are filled in with US or Canada details - eg which state do I enter (there is no "other" option), also the post code - ours is 4 digit it wants a 6 digit code.
Perhaps I can make contact in another way.
Regards.
