Chicken Meal

Rendering is how the poultry industry turns what does not sell as fresh meat into a stable feed ingredient. Heat and pressure kill bacteria and drive off water and fat, leaving mostly protein and minerals.^1,5,7

1. 01 // Source Flesh, skin, bone Chicken parts that do not go to the meat case, with the bone attached. No feathers, heads, feet or guts.
2. 02 // Process Cooked Batch cookers in the plants studied ran for about 70 to 125 minutes, killing bacteria.
3. 03 // Process Fat pressed out Melted fat drains off and is pressed out, then sold on as a separate ingredient.
4. 04 // Process Dried and ground Solids are dried to under 10% moisture, ground to an even meal and dosed with an antioxidant.
5. 05 // Output Chicken meal A dry, shelf-stable meal of about two-thirds protein, ready to be weighed into kibble.

1. 01

   Protein without the water

   Fresh chicken is weighed wet, and most of that water cooks off in the extruder. Meal arrives dry, so each pound adds protein the finished kibble keeps.¹

2. 02

   Stores like a dry good

   It ships and stores without refrigeration, and the recipe does not have to be rebalanced around its moisture before extrusion.

3. 03

   The industry standard

   US pet food used about 192,000 tons of chicken meal in a year, and it is one of the three most frequent animal ingredients on dog food labels.⁸

How much In kibble it usually works as the main protein, often listed just behind fresh chicken, which it outweighs once the water is gone.¹

1. Brands say

   More protein than fresh chicken

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Per pound as sold, yes: about 67% protein on a dry basis and almost no water. The gap narrows in the dog, since rendered chicken's lysine was 79% digestible against 87% for raw.^1,2

2. Critics say

   Rendering heat lowers the protein quality

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Rendered chicken meal scored lower than raw or steamed chicken for amino acid digestibility in rooster assays, and a dog study found its methionine less available than pea protein's. The loss is real and moderate.^2,3,4

3. Owners say

   Chicken is a common allergen

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Chicken was the trigger in 45 of 297 dogs with proven food reactions, behind beef and dairy. Food allergy itself is uncommon, and those counts mostly mirror what dogs were eating.⁹

4. Critics say

   Meal is a low-grade filler

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   Even poultry by-product meals, a lower grade, digested at 80 to 89% for protein in dogs. Chicken meal is a concentrated animal protein, just not the best-preserved form of chicken.^2,6

5. Brands say

   A natural source of glucosamine for joints

   Outruns the evidence

   Evidence

   1. Strong
   2. Some
   3. Thin
   4. None

   One chicken meal sample tested at 0.4% glucosamine. Even purified glucosamine with chondroitin did not beat placebo for dogs with hip arthritis in a 2023 trial.^10,11
