Today the breed is a beef breed in France. that is managed somewhat like dairy over here.
It isn't even called Maine Anjou anymore but Rouge des Pres. i think that is because of a lawsuit. Rouge des Pres translates to reds in the field.
Selection for muscling has given many double muscled individuals in the breed. debatable. they select for carriers to generate double muscled calves, but whether carrier status adds muscle or not is not well defined. supposedly fear this is a carrier, he's thick, so it would be nice to find out what the deal is. there are two strains of double muscling calves, and both strains truncate a protein very early as opposed to very late, on which another breed bases it's product, as it's very late and imparts very tender almost mushy meat.
The French breeders are aware of their calving problems and are trying to select for calving ease since calving problems are hurting them in France versus the Charolais and Blonde D'Aquitaine. some of the double muscle free bulls are calving ease bulls, so double muscling carriers may indeed be more massive.....
All the AI bulls in France undergo rigorous progeny testing and the selection process takes around 5 years. Generally a bull of any breed in France has been pulled inside out before he is approved for general AI use. literally. some of the pictures still have zippers on the cows and it is supposedly routine to perform c-sections.
Do you think they would tolerate having bulls inferior to their sires in such a situation? hmm, most breeds have gone directions that limited diversity to conditions, wouldn't hold the europeans or anyone on a pedestal for idealism. the hallowed angus "tolerated" defects for decades. no one is exempt from tolerating things which may create unintended consequences.
Compare this to the average clubby bull where no objective performance or calving data exists. The French Rouge des Pres breeders select for cattle that do best in their environment where high performance is a must on generally lower quality feedstuff where size has an advantage for efficiency according to some research.
Producing a show winner is icing on the cake, not the reason the breed exists. the show winners become the 25 or so that get registered, so showing is part of the reason they exist. their system, to me is accelerating a homogeneous population that can not travel to eat, hence the pictures of them being managed like a dairy with all their feedstuffs in bunks. yes, many are on pasture as well. this is actually a strength as far as temperament goes because they have been around man closely for generations.
most farms in europe are small, so cattle don't have to travel.
investigate when they are slaughtered. i think you will be amazed. it's almost like heavy veal. the maine growth curve is something that over here rears it's head all the time and is toned down with terms like "later maturing" which means they will get big, yes, as big as heavy steers in the 80's.
