Actually from my understanding the Aussie's have ALWAYS tested for it, and had located several American Angus bulls that were carriers. They did the actually breeding and came up with the verification many years ago. But, the good ol' boys club, oops, I meant the aaa, decided they had to have a dna test to "confirm the results". And so it has been going on and on and on HERE, when in Australia it is cut and dry.

Yes, many times the calf is born dead, and if not, without serious and comprehensive help, the calf will not nurse and therefore die. Those that do live, are very poor doing, many times only growing to 450-500 pounds at yearling age.
There also has been reported issues with the meat being very tough, very stringy. So, it will be a nightmare if these carcasses hit the market.
Just because they have a test, does not mean they are testing the mutation that actually causes the disease.  They are testing a variant that is close-by but not THE ONE that causes the disease.  See below:

"A marker haplotype associated with FCS has recently been identified in Australia, potentially enabling the development of an indirect Single Nucleotide Polymorphism (SNP) marker test for FCS in Angus cattle (H. Raadsma, personal communication)."
"the locus of mutation is unknown"

From my understanding Australia did the MATINGS to prove the carrier status, and that, IMO is just as good, if not better than the DNA test.
Still does not explain why the aaa hasn't embraced the Aussie list of KNOWN carriers.

Sorry, I didn't know they had done progeny testing.  Yes, I agree that is better.

The article above is I believe old - back before they called NH NH  ;) The Aussies have been aggressive with breeding trials. Samples from the breeding trials as well as cases in the US were used to find linked markers. The causative mutation for FCS has been identified and the test is being verified.

Nice cows Aussie

For all you Angus people out there the link above is to an article by Dr Denholm who is a veterinarian responsible for much of the research on FCS as well as increasing the awareness of US and Canadian Angus breeders - good article with pictures
