21 Dog Foods without By-Products

I’ll start this article by telling why you why should always feed your dog food without by-products.

I’ll explain why and hope it’s not a stretch.

Millions of pets are killed every year in the United States because they are not wanted or their owners can’t afford to take care of them. The tragedy doesn’t end there as some of these animals are turned into pet food. That means dog diets formulated from by-product materials may have once been someone’s cherished companion.

There is a better way, though. You can buy dog food that doesn’t contain by-products.

What are by-products in dog food?

By-products are rendered animal parts that come from slaughterhouses. They can include anything from eyeballs to intestines to spinal cords. Yuck!

AAFCO defines by-products as secondary products produced in addition to the principal product. It’s a safe assumption that by-products are not the parts of the animal you would normally think of eating, such as the meat, bones, or organs.

The FDA has classified by-products as “adulterated” because they are not fit for human consumption. So why are they in pet food? It’s simple economics. By-products are a lot cheaper than meat, so they help keep the cost of pet food down.

According to AAFCO, unprocessed or raw by-products are not allowed in pet foods. On its website, AAFCO states that;

“Raw, unprocessed byproducts are prohibited from use in finished animal feed unless the products are heat-treated to kill any microbial contamination. In commercial pet food manufacturing, both canned and kibbled products are heat-treated during manufacturing and packaging. Additionally, many animal protein products are heat-treated at rendering plants and made into dry meals before shipment to a pet food manufacturer. “

AAFCO definition of unprocessed raw by-products

AAFCO went further to state that in commercial pet food diets, correct heat treatment of commercially-manufactured pet foods should eliminate any microbial contamination. However, it’s important to note that by-products are still not fit for human consumption.

4-D Animals in By-Product Diets

The main problem with by-products is that you don’t know what parts of the animal are included. For example, 4-D animals (dead, dying, disabled, or diseased) may be used in pet food. These animals may have been put down because they were sick or injured and not fit for human consumption.

In 2007, the FDA issued a recall of pet food made with 4-D meat from China. The pet food was contaminated with melamine, which is used to make plastics. Pets who ate the contaminated food became sick, and some died.

The FDA does not require pet food companies to list the source of by-products on the label. So, unless the company voluntarily discloses this information, you won’t know where the by-products in your pet’s food come from.

Definition of by-products by AAFCO

Some common by-product diets in dog and cat food products include;

  1. Meat by-products: Lamb, Venison, beef, or Pork
  2. Poultry by-products: Turkey, chicken, or duck by-products

Meat by-products:

AAFCO defines meat by-products as

“non-rendered, clean parts, other than meat, derived from slaughtered mammals. It includes, but is not limited to, lungs, spleen, kidneys, brain, livers, blood, bone, partially de-fatted low-temperature fatty tissue, and stomachs and intestines freed of their contents. It does not include hair, horns, teeth and hoofs. It shall be suitable for use in animal feed.”

AAFCO Defintion of Meat By-products

In contrast, this is the definition of meat by AAFCO:

“Clean flesh derived from slaughtered mammals and is limited to that part of the striate muscle which is skeletal or that part which is found in the tongue, in the diaphragm, in the heart or in the esophagus; with or without the accompanying and overlying fat and portions of the skin, sinew, nerve, and blood vessels which normally accompany the flesh.”

AAFCO Defintion of Meat

Poultry by-products:

AAFCO defines poultry by-products as

“non-rendered clean parts of carcasses of slaughtered poultry such as heads, feet, viscera, free from fecal content and foreign matter except in such trace amounts as might occur unavoidably in good factory practice”

AAFCO Defintion of Poultry By-products

In contrast, below is how AAFCO defines poultry;

“Clean combination of flesh and skin with or without accompanying bone, derived from the parts or whole carcasses of poultry or a combination thereof, exclusive of feathers, heads, feet and entrails. It shall be suitable for use in animal food. “

Meat By-products vs Meat Meals:

The main difference between meat by-products and meat meals is that meat by-products are not as heavily processed as meat meals. Meat by-products can include organs, bones, and blood, while meat meals are usually just the muscle tissue.

Meat by-products are often used in pet food because they are a cheaper source of protein than meat meals. However, some pet food companies are now starting to use more meat meals in their products because they are seen as a more premium ingredient.

Meat meals are rendered which means that they are cooked down at high temperatures to remove all the water and fat. This process concentrates the protein and makes it easier to digest.

Examples of meat meals are;

  1. Meat Meal
  2. Meat and Bone Meal
  3. Poultry Meal
  4. Animal By-Product Meal
  5. Poultry By-Product Meal

Benefits of By-products:

By-products can be a good source of protein and other nutrients for pets. They can also be a cheaper alternative to meat meals.

With limited processing, some proponents claim that its protein is not denatured and is more biologically available to pets.

Drawbacks of By-products:

The main drawback of by-products is that they are not as heavily regulated as meat meals. This means that there is no guarantee of the quality or safety of the ingredients.

Another concern is that by-products may contain harmful chemicals, such as melamine. In 2009, the FDA issued a recall of pet food made with 4-D meat from China. The pet food was contaminated with melamine, which is used to make plastics. Pets who ate the contaminated food became sick, and some died.

Alternatives to By-products:

If you are concerned about the quality or safety of by-products, you can look for pet food that is made without by-products such as meat meals. Also make sure not to confuse animal by-products and animal by-product meals.
