meet Belgian Blue Cattle which is famous for their double muscling due to a gene that suppresses the production of Myostatin. This breed produces extraordinary amounts of meat but critics call Belgian blues ‘monster cows’ and some countries have advocated to eliminate the strain.
Belgian Blue Cattle....when scientist get a hold of an animal, I just can't favor this kind of thing. I love science, but let the animal be normal. Crossbreeding is fine, unless you are messing with gene implantation, artificially, or adding or removing something. In my opinion, that behavior comes from greed at the animals' expense.
