Q: What is Arthrogryposis Multiplex (AM)? back to top
A: Arthrogryposis Multiplex (AM), commonly known as Curly Calf Syndrome, is a genetic defect with a simple recessive pattern of inheritance. This means cattle can be carriers of the defect and appear normal. Two carriers must be mated to get an AM calf, which is born dead with a spine that is bent or twisted.

Q: What breeds are affected? back to top
A: Primarily Angus, but any animal or breed that has been influenced by Angus can be affected, such as Limflex, Sim-Angus, Brangus, Balancers or commercial cattle.

Q: How do I prevent AM? back to top
A: Since AM appears to be a simple recessive condition, 25% of calves from matings of two AM carrier parents can be born with the condition. Therefore, AM carriers should not be bred to other carriers. AM carriers are normal in every other respect, and AM calves can be prevented by mating carriers with noncarriers. Half of an AM carrier's offspring also will be carriers, which means this is a genetic disease that may need to be managed over several generations.

Q: Which cattle should I test? back to top
A: You only need to test animals of unknown pedigree if you would like 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.

Q: What if I am unsure of an animal's pedigree or its likelihood of being a carrier? back to top
A: You only need to test animals of unknown pedigree if you would like 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.
Q: Can I get the Igenity profile with AM? back to top
A: Yes. Simply indicate which samples need both the Igenity profile and AM test on the order form from Igenity.
