I am more than a little confused here.




Those type calculations are usually done on a dry weight basis. Apples to apples comparison. Natural food is what they have evolved to eat and best meets their needs. Pelleted food is good and improving but is not a complete substitute for natural forage. That is why it is called supplemental feeding.
