Arthrogryposis Multiplex (AM) list of bulls tested so far

16th August 2021

Please see below a list of bulls that have been tested for Arthrogryposis Multiplex (AM) so far.

Thank you to Semex for sharing this data with us, we believe they are the only company to have tested their bulls at the moment.

At the moment Semex only have the results for bulls less than five years old and as you will see its shows AMC and AMF Bulls.

AMC means they are a carrier of the recessive and AMF means they are free of the recessive.  

Once we have more data available on tested bulls we will continue to share with members.
