These common pet food ingredients are loathed by many. Yet they ’ ra accepted … and tied revered … by others.
Fans claim animal by-products are nutritionally no unlike than any early type of kernel. And they blame the ingredients ’ noted unpopularity on the unsavory genial trope they invoke .
Something supporters like to refer to as “ the yuck factor ” .
Critics, on the early bridge player, insist these ingredients are nothing more than inedible waste of inferior nutritional value .
What Are Animal By-Products?
animal by-products are what’s left of a slaughtered animal after the skeletal brawn meat intended for human consumption has been removed .
Or according to the USDA …
“ Animal by-products include all parts of a live animal that are not part of the dressed carcass. ”
These processing leftovers ( known as offal ) include those parts of an animal which have been “ rejected for human use and can be expected to be processed into animal prey ” .
Giblets ( livers, hearts, gizzards and necks ) arsenic well as other organs can distillery be sold a edible meats as they are… or used as ingredients to make hot dogs, bologna and sausage .
Unfit for Human Consumption… OK for Dog Food?
animal by-products classified as “ inedible ” and “ unfit for human consumption ” can still be sold for function in pet food .
Some inedible waste can be used to produce wet or dry positron emission tomography food as it is, soon after slaughter…
While early rejected waste can be rendered into kernel or domestic fowl meal products .
In any case, keep in mind…
What makes some by-products fit for human pulmonary tuberculosis ( and others not ) international relations and security network ’ thymine constantly a topic of what they are…
But besides, how they’re handled after butcher .
By-products that are not refrigerated immediately after butcher but stored for hours in a hot offal trailer cannot be sold for human consumption…
But they can still be legally used for making pet food .
Turning Inedible Waste into Pet Food

Rejected lay waste to such as dead farm and zoo animals that have been declared unfit for human consumption can first be rendered into meal ingredients…
And then be used to make pet food .

Feed-Grade vs Pet-Food-Grade
In the specific cases of chicken and poultry, there are 2 grades of by-product meals…
- Feed grade by-product meal
- Pet food grade by-product meal
In an significant 2003 study, darling food grade by-product meal was compared to feed grade by-product meal .
Pet food grade by-product meal was found to be…
- Higher in protein
- Lower in ash
- More digestible
- More consistent
Bottom line ?
All things considered, pet food grade by-product meals are superior to feed grad by-product meals .
unfortunately, without contacting the manufacturer, there ’ s no way to know which type of by-product meal is in any frank food .
The 2 Ways to Describe Animal By-Product Meals
Based upon the source of their raw materials, there are two ways to identify by-product meals .
- Named by-product meals
- Generic (anonymous) by-product meals
Named by-product meals have one thing in coarse. They all clearly identify the source species of the by-products that was used to make the meal .
thus, on a pet food label…
You ’ ll find oneself named by-product ingredients like…
- Chicken by-product meal
- Turkey by-product meal
- Poultry by-product meal
- Beef by-product meal
And although named by-product meals may not be considered the highest quality ingredients, they can be considered acceptable .
The One Type of Animal By-Product You Must Avoid
On the early hand…
Generic by-product meals are different. They do not identify the generator of the kernel .
alternatively, they use vague and non-specific names like…
- Meat meal
- Meat and bone meal
- Meat by-product meal
- Animal by-product meal
What ’ second more…
Generic kernel meals can also contain …
- Road kill
- Dead zoo animals
- Dead on arrival poultry
- Diseased and dying livestock
- Euthanized dogs and cats (unlikely today, but still possible)
Because you can never know the source of the kernel used to make generic by-product meals, purchase of favored food products containing anonymous names should be avoided .
Nutritional Differences… Real or Imagined?
When comparing animal by-product meals with their “ regular ” meal counterparts, the differences can be nutritionally insignificant .
For example, in the case of rendered ingredients, the digestibility, biological rate and amino acid content of both domestic fowl and poultry by-product meals are nearly identical .
then, if there ’ s little nutritional deviation between the two, why then do some companies use kernel by-products… while others don ’ triiodothyronine ?
The Real Reason Dog Food Companies Use Animal By-Products
There ’ s one glower and incontestable reason animal by-products remain indeed popular with some manufacturers… and not others .
Animal by-products are simply cheaper … notably cheaper than most any other comparable kernel product. They ’ re used for making frump food because they save money. not because they ’ re more alimentary.
Why is this authoritative to a pet food shopper ?
Although finding animal by-products in a recipe doesn ’ triiodothyronine guarantee you ’ ve discovered a good or a bad frank food, their bearing must constantly be considered a reliable clue the food is made with cheaper ingredients .
The Bottom Line
With the sole exception of precisely identified organ meats, two rules will help you navigate the jumble global of meat-based frump food ingredients .
- Never pay top dollar for any dog food that lists animal by-products near the top of its ingredients list.
- Never buy any dog food containing generic animal by-products sourced from materials a manufacturer fails to clearly identify.
