Gigantic Belgian Monster Cows

I can't help but stare at these huge monster cows! Apparently, they originate in 19th century Belgium by crossing local cattle with British cattle.

The Belgian Blue cattle are gigantic bovine wonders. Their enormous size and muscle mass, sometimes called "double muscling," is a naturally occurring mutation of the gene for myostatin, a protein that regulates muscle growth. This mutation results in accelerated lean muscle growth.

For show, they're often shaved to show off their muscle growth.

See this video below for a little insight into their "development". Watch as they collect the semen from one bull for artificial insemination (not kidding!)
