Which animals should be tested?
Not all Angus-influenced animals will necessarily need to be tested. AM is believed to have originated with Rito 9J9 of B156 7T26, Registration No. 9682589. Therefore, animals descending from this bull should be highest priority for testing.
What if producers are unsure of an animal’s pedigree or its likelihood of being a carrier?
Animals with unknown pedigrees only need to be tested if producers to mate them to a known AM carrier or an animal of unknown AM status. Using AM-free sires on cows with unknown AM status will prevent AM calves, but not AM carriers.
