Why shouldn't corn be in kibble food?

Answer 1

Well, I can tell you that it doesn't fully digest in a dog's digestive tract. But, the proof is, that a dog fed with a corn based kibble will produce about twice as much poop! as the dog fed a meat based kibble with rice as the grain > http://www.thepetcenter.com/imtop/contrast.html.
Feeding even the more expensive corn based foods will cost you about 23% more per month, than feeding a meat based premium kibble.
Many dogs have corn allergies. It is the first suspect in poor skin conditions.> http://dogs.about.com/cs/dietandnutrition/qt/corn_free.htm
Dogs that are hyperactive will very often calm way down to a better learning condition, if corn is eliminated from the diet. Corn converts to sugars too quickly, and feeds hyperactivity, just as sugar does to children.

Answer 2

Because its very fattening and many dogs are alergic to it and it's harder to digest then rice or soy if a grain is wanted at all. There are plenty of fillers, inexpensive ingrediants, that have better nutricional value.-----"The top three ingredients in pet foods, particularly dry foods, are almost always some form of grain products. Pedigree Performance Food for Dogs lists Ground Corn, Chicken By-Product Meal, and Corn Gluten Meal as its top three ingredients. 9 Lives Crunchy Meals for cats lists Ground Yellow Corn, Corn Gluten Meal, and Poultry By-Product Meal as its first three ingredients. Since cats are true carnivores — they must eat meat to fulfill certain physiological needs — one may wonder why we are feeding a corn-based product to them. The answer is that corn is a much cheaper “energy source” than meat.
