Chicken Fat

Chicken processing leaves skin and fatty tissue after meat is removed. Renderers heat that material to release its fat, then separate the fat from water and protein solids. Pet food makers use the recovered fat in recipes and coatings.^1,4,10,11

1. 01 // Source Chicken fatty tissue Skin and abdominal fatty tissue from chicken processing provide material for rendering.
2. 02 // Process Heated Heating releases fat from the tissue and separates it from protein solids.
3. 03 // Process Fat separated Rendering equipment separates the released fat from solids and water.
4. 04 // Output Chicken fat The recovered fat goes to pet food plants, where it may coat dried kibble.

1. 01

   Adds concentrated energy

   Rendered fat adds energy without the water in fresh tissue. In a dog trial, kibble coated with chicken fat had more calculated energy than the uncoated food.^1,5

2. 02

   Supplies linoleic acid

   Chicken fat contains linoleic acid, which dogs need from food. Its contribution depends on how much fat the recipe uses and what other fats it contains.^4,5

3. 03

   Coats finished kibble

   Manufacturers spray heated fat onto dried kibble. Coating puts fat on the surface, where it affects smell and taste, though dogs do not always prefer poultry fat.^1,2

4. 04

   Uses recovered poultry fat

   Rendering turns fatty poultry tissue into a saleable feed ingredient. Authors of a chicken fat coating study also identify affordability as a reason manufacturers use it.^1,10

How much One dog trial sprayed chicken fat onto finished kibble at 5% of its weight, alongside a separate flavor coating.¹

1. Brands say

   Chicken fat adds concentrated, digestible calories

   Evidence

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

   In a 36-dog trial funded by the poultry industry, kibble with a 5% chicken fat and flavor coating had 3755 versus 3499 kcal/kg dry in the uncoated food. The comparison does not isolate the fat from the flavor coating.^1,5

2. Brands say

   Chicken fat makes kibble more appealing

   Evidence

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

   A 30-dog preference test favored sunflower oil over poultry fat. Another trial found uncoated kibble less accepted, but added flavor alongside chicken fat. Coating affects appeal; chicken fat has no proven special edge.^1,2

3. Brands say

   Chicken fat gives dogs a glossy coat

   Outruns the evidence

   Evidence

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

   After 9 weeks, dogs given both added zinc and linoleic acid had glossier coats than controls. The trial did not isolate linoleic acid or test chicken fat, so a coat promise from this ingredient goes too far.^3,4

4. Owners say

   Chicken fat is safe for chicken allergic dogs

   Outruns the evidence

   Evidence

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

   A poultry fat reference rounds protein to 0%, and protein is the usual food allergen. That does not prove every chicken fat ingredient or ordinary kibble is free of stray protein. No cited trial challenged chicken allergic dogs with chicken fat.^5,8

1. 2019 // Feeding trials, 2 fats

   Dogs absorb poultry fat as fully as corn oil¹⁴

   Adult dogs: 8 in one trial, 9 in another. The fat tested was poultry offal fat, a close cousin of chicken fat.

   Found. Dogs digested 97.94% of the fat in a poultry offal fat diet and 98.62% in a corn oil diet, a difference that was not significant. Energy content and stools did not change as corn oil replaced poultry fat.

   What it means. Poultry fat is nearly fully absorbed, but a plant oil does the same energy job. Neither fat is a better fuel.

2. 2025 // Feeding trial, 3 foods

   Poultry fat beat insect fat on digestion and taste¹²

   18 adult Golden Retrievers, 6 per food, plus 20 dogs in a taste test. University funded.

   Found. Over 30 days, replacing all 6% poultry fat with insect larvae fat lowered fat digestibility. In a two bowl test, dogs preferred the poultry fat food. Blood values and stool scores did not differ.

   What it means. In this one small trial, a full swap to black soldier fly larvae fat cost some fat digestion and appeal compared with poultry fat.

3. 2025 // Feeding trial, 6 foods

   A plain chicken fat coating barely changed fat digestion¹

   36 Labrador retrievers, 6 per food. Funded by a poultry industry council.

   Found. Kibble coated with plain chicken fat had 91% fat digestibility against 90% for uncoated kibble. Only a coating with 20% added oleic acid reached a clearly higher 97%.

   What it means. A chicken fat coating adds calories without harming fat digestion, but it does not make the rest of the food better digested.

4. 2018 // Feeding trial, 2 diets

   More linoleic acid changed skin fats, not skin water loss¹³

   10 healthy dogs in two groups of 5. Funded by Waltham and Royal Canin.

   Found. Over three months, dogs fed more linoleic acid showed high increases in linoleic acid and free ceramides in the outer skin layer, while water loss through the skin was nearly unaffected.

   What it means. Dietary linoleic acid does reach the skin, but extra amounts in healthy dogs did not measurably improve the skin barrier.
