Bull with unrestricted muscle growth

Bulls with a mutation that limits muscle growth have unrestricted bulk, making them especially hench!

The lack of myostatin allows more muscle fibers at birth, and Bulls born with a myostatin deficiency can achieve massive size, with weight and strength far exceeding normal cattle. 

Without the protein that typically restricts muscle fibers, these "double muscled" bulls can grow to hold enormous bulk and power. 

Reports indicate Belgian Blue bulls of this type can weigh up to 5,000 pounds and produce beef with much less fat but more muscle mass.
