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:Show Heifer said: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.
"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"
