Modern Japanese selection and genetic development at all levels is informed ‘upstream’ from official carcass measurement at the end of the cycle(see a snapshot of standard JMGA parameters here).  These formal Japanese grading standards assess numerous carcass traits…

Australian sire selection in crossbreeding is largely predicated by feedlot buyers, specifying in reference to carcass summaries as recorded in feedlot carcass databases.  Derived from these databases, early, largely anecdotal Wagyu sire ranking information relates mainly to this XB…
