Poultry Fat

Poultry processing leaves tissues that contain recoverable fat. Rendering plants heat those tissues and separate the melted fat from water and solids, creating a saleable ingredient for pet food and other uses.^4,7

1. 01 // Source Poultry tissues Processing trimmings contain fat alongside water, protein and connective tissue.
2. 02 // Process Heat the tissues Rendering melts the fat so it separates from the water and protein around it.
3. 03 // Process Clarify the fat Decanters remove water and solids; a separator can further clean the liquid fat.
4. 04 // Output Rendered poultry fat The separated fat goes to pet food makers as an energy ingredient or kibble coating.

1. 01

   Adds concentrated calories

   Separated fat raises a recipe's energy and fat content without adding the water and protein in poultry tissues. Makers can adjust it apart from the protein ingredients.^4,7

2. 02

   Supplies linoleic acid

   Poultry fat contributes linoleic acid, which appears in dog food nutrient profiles. The complete recipe, rather than this ingredient alone, must supply enough.^4,5

3. 03

   Coats finished kibble

   Manufacturers spray heated fat onto dried kibble after cooking. AAFCO describes added fats as supplying flavor, and a 30-dog test of three equally coated fats found sunflower oil preferred over beef tallow, showing fat choice affects preference once kibble is coated.^1,6

4. 04

   Uses a poultry fat stream

   Rendering makes a separate product from fat in poultry processing tissues. An industry survey found substantial chicken fat purchases for dog food, showing the commercial scale of this use.^7,8

How much A dog preference study tested a 5% poultry fat coating; that tested amount is not a standard amount for every recipe.¹

1. Brands say

   Poultry fat supplies an essential fatty acid

   Evidence

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

   The composition table lists an average of 191 g/kg linoleic acid on a dry basis, and AAFCO specifies a minimum for complete dog food. Poultry fat contributes it; the whole recipe determines whether the food meets the minimum.^4,5

2. Brands say

   Poultry fat makes kibble irresistible to dogs

   Outruns the evidence

   Evidence

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

   In a 30-dog test, three kibbles wore equal 5% coatings of poultry fat, sunflower oil or beef tallow. Sunflower oil won preference 56% of the time over beef tallow's 44%, and the abstract does not report a poultry fat preference rate at all.¹

3. Brands say

   Poultry fat gives every dog a shinier coat

   Outruns the evidence

   Evidence

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

   In a 9-week supplementation phase, researchers tested zinc alone, linoleic acid alone and both. Coat gloss improved in the combined group against controls. The abstract reports no gloss benefit for linoleic acid alone, and poultry fat was not tested.^3,4

4. Owners say

   Chicken allergic dogs can safely eat poultry fat

   Outruns the evidence

   Evidence

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

   The composition table lists no protein in poultry fat, but it describes the ingredient rather than testing allergy safety. The cited dog allergy sources did not challenge poultry fat specifically, and retail diets can contain contaminant proteins.^4,10
