Copper boosts pig growth, and now we know why
(PHYSorg.com Biology)

Pigs have better feed conversion rates with copper in their diets, but until now, scientists didn`t fully understand why. Existing research from the University of Illinois shows copper doesn`t change fat and energy absorption from the diet. Instead, according to new research, the element seems to enhance pigs` ability to utilize fat after absorption, resulting in increased energy utilization of the entire diet.
