This must be one of the strangest things I've seen in quite some time. This video by National geographic shows a breeding program where cows and bulls with a gene that allows their muscles to grow larger than normal have been bred. Through this natural selection, they've developed a line of cattle that's just MASSIVE. Check them out on the video bellow.
The technical name for these cows are Belgian Blue Cattle, but there are also called the Super Cows and the Hulk Cows.
This breed is becoming very popular because of its high meat yield and low fat percentage. prices range from 1500$ to 3000$ and the meat according to the MNP Farm website has less fat, less calories and less cholesterol than fish, chicken and traditional beef. Click here for more pictures.
