Brewer's Rice is the small milled fragment of rice kernels that have been separated from the larger kernels of milled rice. Brewer's rice is a lower quality rice product that is missing many of the nutrients found in ground rice and ground brown rice. It is basically a waste product of the alcohol industry.
Corn Gluten Meal is the dried residue from corn after the removal of the larger part of the starch and germ, and the separation of the bran by the process employed in the wet milling manufacture of cornstarch or syrup, or by enzymatic treatment of the endosperm. Corn gluten in dog foods is cheap protein filler.
Poultry By-Product Meal consists of the ground, rendered, clean parts of the carcasses of slaughtered poultry, such as necks, feet, undeveloped eggs, and intestines; exclusive of feathers except in such amounts as might occur unavoidably in good processing practices. This is a low-quality, inconsistent ingredient, with multiple organs used, constantly changing proportions, and questionable nutritional value. The origin can be any fowl (turkeys, ducks, geese, buzzards, etc.), instead of a single source, like chicken. Poultry by-product meal is much less expensive and less digestible than chicken meal.
Animal Fat: Animal fat is a "generic" fat source that is most often made up of rendered animal fat, restaurant grease, or other oils too rancid or deemed inedible for humans. Look for a named fat source, such as poultry or chicken fat, that is naturally preserved.
Animal Digest: A material which results from chemical and/or enzymatic hydrolysis of clean and undecomposed animal tissue. Animal digest is a palatability enhancer, which can contain unpredictable parts from animals of unknown origin.
Salt: While salt is a necessary mineral, it is also generally present in sufficient quantities in the ingredients pet foods include. Just like for humans, too much sodium intake is unhealthy for animals. In poor quality foods it is often used in large amounts to add flavor and make the food more interesting.
Menadione: Toxic.
