I have heard different claims, so I thought I'd check out how the AAFCO (Association of American Feed Control Officials) defines these terms:

Chicken:
Definition: Chicken is the clean combination of flesh and skin with or without accompanying bone, derived from the parts or whole carcasses of chicken- exclusive of feathers, heads, feet, and entrails.

Chicken Meal: chicken (see defination above) which has been ground or otherwise reduced in particle size."


Chicken by-product:
Definition: Chicken by-product meal consists of the ground, rendered, clean parts of the carcass of slaughtered chicken, such as necks, feet, undeveloped eggs and intestines, exclusive of feathers, except in such amounts as might occur unavoidable in good processing practice.


What I have heard from food sales reps (take it for what it is worth), is that the difference between listing chicken and chicken meal, is that the moisture and fat are removed prior to cooking, which means the actual meat content is higher in chicken meal then if it is just listed as chicken. This is also supported by several food comparison sites, and the definitions of the AAFCO.

(I used chicken as an example, but would apply to any meat)
