Selective Breeding Produces the SUPER COW!

submitted by blankfist

1 decade 6 years 7 months 4 weeks ago

From http://en.wikipedia.org/wiki/Belgium_Blue:

Belgian Blue cattle are a heavily-bred breed, producing extraordinary amounts of meat. The sculpted, heavily muscled appearance is known as "doubled muscled", and is a trait shared by the Piedmontese breed. Critics call Belgian blues "monster cows" and some countries have advocated eliminating the strain [1]. They are often unable to give birth without caesarean section.

Belgian blue has a natural mutation of the gene that codes for myostatin, a protein that counteracts muscle growth. The truncated myostatin is unable to function in this capacity. This mutation also interferes with fat deposition, resulting in very lean meat.
