Early cattle served a triple-purpose. They provided meat, milk and labor to their owners. Eventually their purposes were changed and they were selected more for single or in some cases dual purposes. Today, cows are genetically modified to produce more muscles. These cows generally have shorter legs and a stumpier look. Humans have exaggerated genetics to get desired traits and there are currently over 800 different modified cattle. The dairy cattle qualities are focused on the size of the udders and the skin, while the cattle used for meat focuses on the sheer size of the animal. The English longhorn is an example of a cow that is bred purely for beef. In America, the most popular meat that we use is from the Aberdeen Angus.
