I see that an Angus bull was excluded from last weekend’s Irish Angus elite sale in Carrick-on-Shannon because of the new muscling gene rules introduced.

The new rules were brought in to exclude bulls that carry two copies of the myostatin genes.

The bull in question tested positive for two copies of F94L

That seems very broad to The Dealer.

Surely the society only wishes to exclude bulls with the disruptive mysostatin genes, and not ones which could be of benefit?

This gene doesn’t cause double muscling, but instead increases muscularity without affecting calving traits. Hence its nickname, the “profit gene”. Surely this can only be positive for a breed?
