The world of pet food ingredients can be confusing. Many pet owners scrutinize labels, trying to decipher what’s truly nourishing for their furry companions and what might be considered filler or, worse, potentially harmful. Among the most debated ingredients are “chicken meal” and “by-product meal.” While they both stem from chicken sources, significant differences exist in their composition, nutritional value, and overall quality. Understanding these distinctions is crucial for making informed decisions about your pet’s diet.
What is Chicken Meal?
Chicken meal is a concentrated protein source derived from chicken. The Association of American Feed Control Officials (AAFCO), which sets standards for pet food ingredients, defines chicken meal as “the dry rendered product from a combination of clean flesh and skin with and without accompanying bone, derived from the parts of whole carcasses of chicken or parts thereof, exclusive of feathers, except in such trace amounts as might occur unavoidably in good factory practice.”
The Rendering Process
The key to understanding chicken meal lies in the rendering process. Rendering involves cooking animal tissues to remove moisture and fat. This process concentrates the protein content, resulting in a highly digestible and nutrient-dense ingredient. The rendering process also sterilizes the material, eliminating harmful bacteria and pathogens.
The process typically involves several steps:
- Grinding: The raw chicken materials are ground into smaller pieces to facilitate efficient processing.
- Cooking: The ground material is cooked at high temperatures, typically around 250-270°F (121-132°C), for a specific duration. This process separates the fat and water from the protein and bone solids.
- Pressing: The cooked material is then pressed to extract more fat and water.
- Grinding (again): The remaining solid material is ground into a fine, consistent meal.
Nutritional Value of Chicken Meal
Chicken meal boasts a high protein content, typically around 60-70%. This concentrated protein source is essential for muscle development, tissue repair, and overall health. It also contains essential amino acids, the building blocks of protein, which are vital for various bodily functions.
Furthermore, chicken meal provides a source of minerals, such as calcium and phosphorus, crucial for bone health. The quality of chicken meal can vary depending on the source materials and the rendering process. High-quality chicken meal should be made from clean, wholesome chicken parts and processed under strict quality control standards.
What are By-Products?
By-products, also known as animal by-products or poultry by-products, are the secondary products produced in addition to the principal product. In the context of pet food, these are the non-rendered, clean parts of slaughtered animals, exclusive of meat, such as lungs, spleen, kidneys, brain, livers, blood, bone, partially defatted low-temperature fatty tissue, and stomachs and intestines freed of their contents. It does not include hair, horns, teeth, and hooves.
AAFCO defines “poultry by-product meal” as “the dry rendered product from a combination of clean poultry parts such as heads, feet, undeveloped eggs, viscera, and carcasses, exclusive of feathers, except in such trace amounts as might occur unavoidably in good factory practices.”
The Composition of By-Products
The composition of by-products can vary significantly depending on the animal and the specific parts included. Some by-products, such as liver and kidneys, are rich in vitamins and minerals. Others, like intestines, may have lower nutritional value.
The variability in composition makes it challenging to assess the overall nutritional value of by-products in pet food.
Are By-Products Bad?
The term “by-product” often carries a negative connotation, leading many pet owners to believe they are inherently inferior ingredients. However, this is not necessarily true. Some by-products can be nutritious and beneficial for pets. For example, organ meats like liver are packed with vitamins and minerals.
The concern arises from the lack of specificity regarding the types of by-products used in pet food. Without knowing the exact composition, it’s difficult to determine the nutritional quality and digestibility of the ingredient. Some manufacturers use high-quality by-products, while others may use less desirable parts. The quality differences depend on the source and handling of the materials.
Chicken Meal vs. By-Product: Key Differences
The main differences between chicken meal and by-product meal lie in their composition, processing methods, nutritional consistency, and overall quality control. Here’s a breakdown:
Composition
Chicken meal is a concentrated protein source made from a combination of chicken flesh, skin, and bone. By-products encompass a wider range of ingredients, including organ meats, intestines, and other non-meat parts of the animal.
Processing
Chicken meal undergoes a rendering process, which removes moisture and fat, concentrating the protein content. By-products may or may not be rendered, depending on the specific ingredient and the manufacturer’s process.
Nutritional Consistency
Chicken meal offers a more consistent nutritional profile due to its defined composition and standardized rendering process. By-products exhibit greater variability in nutrient content, making it challenging to predict their overall nutritional contribution to the pet food.
Quality Control
The quality of chicken meal is generally easier to assess due to its standardized production process. By-products can be more challenging to evaluate due to the variability in source materials and processing methods. Look for brands that are transparent about their sourcing and production practices.
Why the Controversy?
The debate surrounding chicken meal and by-products stems from concerns about quality, transparency, and nutritional value. Here’s why these ingredients are often viewed differently:
Transparency Concerns
Many pet owners are wary of by-products because the term is vague and doesn’t specify the exact ingredients used. This lack of transparency makes it difficult to assess the quality and nutritional value of the ingredient.
Quality Concerns
The quality of both chicken meal and by-products can vary depending on the source materials and processing methods. Poor-quality ingredients can lead to digestive issues, allergies, and other health problems.
Nutritional Concerns
While some by-products are highly nutritious, others may have limited nutritional value. The variability in composition makes it challenging to ensure that by-products contribute meaningfully to the pet food’s overall nutritional profile.
Making Informed Choices
Choosing the right pet food can be daunting, but understanding the differences between chicken meal and by-products can help you make informed decisions. Here are some tips to consider:
Read the Label Carefully
Pay close attention to the ingredient list and look for specific information about the source and quality of the ingredients. Be wary of vague terms like “animal by-products” and look for more specific descriptions if possible.
Research the Brand
Choose pet food brands that are transparent about their sourcing and production practices. Look for brands that conduct rigorous quality control testing and have a good reputation for producing high-quality pet food.
Consider Your Pet’s Needs
Different pets have different nutritional needs based on their age, breed, activity level, and health status. Consult with your veterinarian to determine the best diet for your pet.

The AAFCO statement on the pet food label indicates that the product meets the nutritional requirements for a specific life stage. This statement provides assurance that the pet food is nutritionally complete and balanced.
The Role of “Human-Grade” Pet Food
The term “human-grade” in pet food advertising often raises questions about the quality of other ingredients. Human-grade pet food implies that all ingredients are edible and safe for human consumption. While this may sound appealing, it’s essential to understand that AAFCO regulations require all pet food ingredients to be safe and suitable for animal consumption, regardless of whether they are considered “human-grade.”
The focus should be on the overall nutritional value and quality of the pet food, rather than solely on whether the ingredients are labeled as “human-grade.”
Beyond Chicken Meal and By-Products
While chicken meal and by-products are common ingredients in pet food, it’s important to consider the entire ingredient list when evaluating a pet food. Other ingredients, such as grains, vegetables, fruits, and supplements, also contribute to the overall nutritional profile.
A balanced and nutritious pet food should provide a variety of essential nutrients, including protein, carbohydrates, fats, vitamins, and minerals.
Protein Sources
Protein is an essential nutrient for pets, and it can come from various sources, including chicken, beef, fish, lamb, and plant-based proteins. The quality and digestibility of the protein source are important considerations.
Carbohydrate Sources
Carbohydrates provide energy for pets, and they can come from grains, vegetables, and fruits. Whole grains, such as brown rice and oats, are generally considered more nutritious than refined grains, such as white rice and corn.
