It was tried, openly and covertly, 30-40 years ago.How much Limousin has been put into the South Devon?
But since the breed already carries the double muscled gene - which is nothing but a pain in the backside- it never gained much traction.
Pedigrees are being DNA'ed for stuff nowadays, so it would quickly show up if it were done now.
As said above, the native double muscling can also be associated with things that don't grow....which is a bit daft since 'growing' is one of the breeds strongpoints.
Hi @Cowslip ....nice pics.
I'm currently working a 'Treguddick' polled bull, and have a strapping weaned calf in the shed from 'Pizwell', who apparently is zero for myostatin, and homozygous for polled.
