Right here! Say Hello to the Belgian Blue Cow.
Just from the name you can envision Paul Bunyan and his ox Blue. These cows are built to be big, pumped up and prime. The cows originate in Belgium and have been genetically engineered. In the 2nd half of the 19th century, Shorthorn bulls from the United Kingdom were sent to Belgium to improve the muscle structure of the native cattle population.
These animals were then engineered further for its meat. Although most people believe double muscling means the cow has two sets of muscles that’s incorrect, they just have double the muscle bulk. This is achieved by breaking the gene that controls the secretion of Myostatin, a protein that inhibits muscle growth after a certain point of development.
Some countries such as Denmark think that the strain should be eliminated, but considering that this bulky cow is needed for meat, breeders probably won’t stop letting them breed.
Learn Something Fun: Some say that the origin of Bunyan's last name comes about because "Bonyenne" is a colloquial French-Canadian expression of surprise and astonishment meaning "Good Grief" or "My Goodness"
