#9: That’s One Masculine Bull

Myostatin is a protein found in animals, including humans, that regulates muscle growth. When an animal is born without functional myostatin, it results in a condition known as “double muscling.” This genetic mutation leads to a significant increase in muscle mass and reduced body fat. Animals with this condition, such as cattle and some dog breeds, exhibit extremely muscular physiques and enhanced strength.

In livestock farming, the absence of myostatin has been selectively bred to create animals with more desirable meat yields. However, it’s important to note that while increased muscle mass can have economic benefits in agriculture, it may also lead to health concerns and ethical considerations in animals.
