double muscling

[knabe]

all breeds don't have defects until they do.


defects are a sign of breed impurity.


what is a breed.


usually a selection of a sport is what led to breeds in the first place.


this misplaced obsession of what a breed is almost a religion.


has the same pagan, non-believer outcasting reinforcement, the altar (pedigree) etc.

DM in Shorthorn can came from Chianina and Maines.
UK Shorthorn are full of DM, they used Maine Anjou massivelly as well as some NA genetics with Maine, as Trump on ancestors.
Here, I inspected some calves for register, found 3 DM. Descarded!
Sired by a canadian bull, that show a strong muscle on back.

You've got that backwards - my understanding is that the double muscling in the Maines came from the Durham Shorthorn cattle that were used to create the Maine Anjou breed. That is also where the Belgian Blue got there double muscling. So the cattle in the UK may have gotten it from the Maines that were bred back in, but there was probably some still in their own population.

As to the Canadian bulls siring double muscling - yes there are a few known in very popular bloodlines.

Agree, it's possible. As some DM animals are appearing on Normande too. Also can be an atavic gene hidden on European population - France, Belgian and The Netherlands.

By the way, with high influx genetics in and out on Shorthorn, we can reach to a point that to ask ....How was first created, the egg or the chicken?

This is the first that I have heard of DM in the Normande breed.  They are one of the few breeds that we register that they have not introduced any outside breed influence that we have found.
