Here is what the dog food project has to say about chicken by-products as an ingredient in dog food.
""
Chicken Byproduct Meal AAFCO: Consists of the dry, 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 unavoidably in good processing practices. Chicken byproducts are much less expensive and less digestible than the chicken muscle meat.The ingredients of each batch can vary drastically in ingredients (heads, feet, bones etc.) as well as quality, thus the nutritional value is also not consistent. Don't forget that byproducts consist of any parts of the animal OTHER than meat. If there is any use for any part of the animal that brings more profit than selling it as "byproduct", rest assured it will appear in such a product rather than in the "byproduct" dumpster.
I would expect this from a bottom of the line supermarket dog food, not a pricey dog food. And if you run a company today, and can't afford to have someone design a couple of web pages about your product, I doubt if you are going to buy top of the line ingredients and put them in your products either.
Here is what R. Abady (an actual feed maker, not a website owner) has to say about Chicken By-Product meal:
...
When ingredients are selected for the production of dog food, there are many different factors that enter into the equation. An ingredient's nutritional yield versus its cost is central to sound dietary construction.
For example -- If ingredient A is nutritionally equivalent to ingredient B, but B costs 3 times as much for the same quantity of A,
then the manufacturer who uses ingredient A can include 3 times more of it in his ration than the manufacturer using ingredient B and therefore
can offer three times more nutrition at no greater cost.
Ultimately, what a manufacturer spends on ingredients is a major determinant of the selling price of nutritional products, therefore the manufacturer who uses ingredient A can offer a significantly better product than the manufacturer who uses ingredient B, for the same cost to the consumer if all other factors are equal.
...
Clear examples of the public being drawn in by
slick advertising are exemplified by the rush toward fresh chicken and turkey-based products, lamb and rice diets and chicken meal-based diets. These diets are claimed to be more nutritious and better for dogs because they do not contain by-products and are more digestible, along with a host of other
equally mythical claims. Since the appeal of these products rests entirely on the claims that are made for the specific ingredients that are supposed to characterize the ration, a close examination of the nutritional values relative to the costs of those ingredients will shed light on the nutritional merits (or the absence thereof) of the ration as a whole.
...
The fresh chicken, turkey or lamb diets have a few interesting twists to them.
First, as there is
no firm standard as to what actually constitutes chicken or turkey, they can be derived from
skin, genitals etc. or even reconstituted meals.
Second, these ingredients are
included in the listing of ingredients with their moisture content intact even though in the final dry product the moisture has been cooked out!
Listing the moisture laden solids can give the impression that three or more times the amounts of solids are in the product than are actually present.
For years the public has been conditioned to believe that ingredients are listed in the order of the amounts included in the formula on an equal basis - each one being at least 90% solids.
This new twist allows large quantities of moisture which does not end up in the finished product to be listed on the label as something other than what it is!
...
Fresh Chicken, Turkey or Lamb Based Diets
By-Products (internal organs) play a central role in the feeding of carnivores, as do muscle meat, fat and bone.
Poultry by-products meal is an economical and nutritious source of high quality animal protein.
It is composed of lungs, heads, gizzards, necks, feet, intestines (without their contents) and other clean parts of the carcass.
Nutritionally it is equal to superior to the ingredients discussed earlier and it costs many multiples less.
It is not true that heads or even feet (which represent only a small component of poultry by-products meal) are undesirable as components of dog food.
While they have little aesthetic appeal to humans, heads contain valuable brain, tongue and ocular tissue, and feet are 20% protein & 16% fat.
Both are rich in various amino acids and fatty acids of the most important varieties.
Among these can be found Arginine (essential for fertility and immune system support) Glycine (a potent free-radical scavenger and a component of glucose tolerance factor which regulates insulin metabolism) and Aspartic acid (which helps with the synthesis of glycoprotein and with the detoxification of ammonia).
Feathers are NOT a component of poultry by-products meal, unless it is of very low quality.
