The Ayrshires Cattle Society of Britain and Ireland has provided a list of bulls that have been tested for Arthrogryposis Multiplex (AM) so far.
They would like to thank Semex for supplying us with this data and 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.
As soon as we have more data available on tested bulls we will bring them to you.
See the list HERE.
