Hey, I copied one of the studies that RC gave us and am posting it here (it's basically saying that the TDN of corn (and it's derived meals respectively) have more digestable nutrients than a few other grains (which I know is not comparing it to animal protein, but keep in mind there are sufficient animal protein in this diet as well):

*The table above compares the nutrient value of several grains commonly
used in pet food. As you can see, corn is superior in several areas,
versus the other grains:
- Corn contributes moderate levels of protein for muscle building
and maintenance.
- Corn contributes higher fat levels for energy and is rich in the
essential fatty acid ? linoleic acid, necessary for healthy skin and a
shiny coat.
- Corn contains a moderate amount of fiber needed for proper
digestion.
- Corn is rich in nitrogen free extract (carbohydrates) which are
used by the pet for energy.
- Corn contains both Vitamin A and Carotene, necessary for healthy
skin, bone growth and vision. Both act as antioxidants and as an immune
system booster.
- Corn contains a higher percentage of total digestible nutrients
and is therefore more bioavailable to the pet.
In conclusion, corn is a highly digestible grain, a great energy source
and an excellent source of linoleic acid making it a good choice for your
pet?s diet.
