What Is Duck Gizzard Powder?
Duck Gizzard Powder is made from cleaned duck gizzards that are dehydrated or freeze-dried and milled into a uniform powder. The gizzard is a muscular part of the avian digestive system. Its dense tissue contains protein, amino acids, iron, zinc and several B vitamins.
Other commercial names include:
- Dried Duck Gizzard Powder
- Dehydrated Duck Gizzard
- Freeze-Dried Duck Gizzard
- Duck Gizzard Meal
- Duck Gizzard Extract Powder
- Ground Duck Gizzard
- Duck Organ Meat Powder
- Freeze-Dried Duck Gizzard for Dogs and Cats
Whole duck gizzard powder should not be confused with Ji Nei Jin, the dried inner lining of the chicken gizzard used in Traditional Chinese Medicine. Ji Nei Jin refers specifically to the yellow internal membrane, while commercial duck gizzard powder normally contains processed muscular gizzard tissue. Products intended for herbal or traditional medicine applications must clearly identify which tissue is used.
Duck gizzard has no single CAS number because it is a natural animal-derived material rather than an isolated chemical compound. The usual product is a beige, tan or light-brown powder with a characteristic cooked or dried poultry aroma. It disperses in water but does not normally dissolve completely because it contains proteins and other natural tissue components.
The standard particle size is 80 mesh. Finer or coarser powders can be produced for pet food premixes, capsules, tablets, soft chews, powdered toppers and research formulations.
Henan Unicorns Biotechnology supplies bulk Duck Gizzard Powder and provides OEM production, contract packaging, custom specifications, private label development and technical documentation for international buyers.
Natural Nutritional Components of Duck Gizzard
Duck gizzard is primarily composed of lean muscular tissue. Its exact nutrient profile varies with the duck species, feeding conditions, raw material preparation, and drying method.
Animal Protein and Amino Acids
Dried gizzard ingredients commonly contain a high proportion of protein on a dry-matter basis. The protein supplies amino acids used in muscle tissue, enzymes, and normal body maintenance. Final protein content should be confirmed on the batch COA.
Iron
Duck gizzard naturally contains heme iron, the animal-derived form of iron. Iron is associated with hemoglobin formation, oxygen transport, and normal red blood cell production.
Zinc
Zinc participates in protein metabolism, skin maintenance, immune function, and tissue repair. Its concentration depends on the raw gizzard and processing conditions.
Vitamin B12
Vitamin B12 is found naturally in animal tissues. It is associated with red blood cell formation, nerve function, and normal energy metabolism.
Niacin and Other B Vitamins
Duck organ meat supplies niacin and smaller amounts of other B vitamins. These nutrients take part in carbohydrate, protein and fat metabolism.
Natural Connective-Tissue Components
Gizzard tissue contains collagen and connective-tissue proteins. Their levels vary according to trimming, raw material selection, and drying conditions.
Indicative Dry-Matter Profile
| Natural component | Typical characteristic |
|---|---|
| Protein | Major component of dried gizzard tissue |
| Fat | Usually lower than fatty poultry tissues |
| Iron | Naturally present as animal-derived heme iron |
| Zinc | Naturally present trace mineral |
| Vitamin B12 | Present in poultry organ tissue |
| Niacin | Naturally present B vitamin |
| Collagen | Derived from connective tissue |
| Moisture | Controlled during drying, generally no more than 10% |
These values are descriptive rather than guaranteed assay figures. Product-specific nutritional testing can be arranged according to the buyer’s intended market.
Duck Gizzard Powder Specifications
Unicorns Biotechnology produces Duck Gizzard Powder from inspected avian raw materials using freeze-drying or controlled dehydration. A typical specification includes moisture of no more than 10.0%, ash of no more than 5.0% and total heavy metals of no more than 10 ppm. Lead and arsenic are controlled at no more than 2 ppm each, cadmium at no more than 1 ppm and mercury at no more than 0.1 ppm.
Microbiological testing covers total aerobic microbial count, yeast and mould, Escherichia coli and Salmonella. Standard packaging is 25 kg per fiber drum with double food-grade polyethylene bags. Smaller bags, cartons and private label retail packaging can be arranged.
Testing methods may include gravimetric moisture analysis, ash testing, ICP-MS or atomic absorption spectroscopy for heavy metals, and current USP microbiological procedures. Each shipment can be supplied with a COA, MSDS, allergen statement, non-GMO statement and other export documents.

Duck Gizzard Powder Benefits
Concentrated Animal Protein
Dried duck gizzard provides concentrated animal protein for dog, cat and specialty animal nutrition products. Protein supplies amino acids required for muscle maintenance, tissue renewal and normal body condition.
Natural Iron Source
The ingredient contains animal-derived iron. Iron is used in hemoglobin production and oxygen transport, making duck organ powder suitable for formulas designed to provide naturally occurring minerals.
Supports Normal Energy Metabolism
Niacin, vitamin B12 and other nutrients found in poultry organ tissue participate in normal nutrient metabolism. The powder can increase the nutritional density of pet food toppers and complementary feeding products.
Supports Skin and Coat Condition
Protein, zinc and amino acids contribute to normal skin structure and coat maintenance in dogs and cats when included as part of a complete and balanced diet.
Lean Organ-Meat Ingredient
Duck gizzard is a muscular organ rather than a high-fat storage tissue. Properly trimmed gizzard powder can provide concentrated protein with a moderate or relatively low fat level, depending on the finished specification.
Alternative Poultry Protein
Duck may be used in rotation diets or formulas that avoid commonly used proteins. The finished product should not be described as hypoallergenic unless the complete formula and manufacturing controls support that claim.
Strong Natural Palatability
The characteristic aroma of dried duck organ tissue can improve acceptance of kibble, wet food, powdered supplements and veterinary nutrition products. Inclusion rates should be established through palatability and stability trials.
Freeze-Dried Duck Gizzard Powder Manufacturing Process
Fresh duck gizzards are collected from approved poultry-processing facilities and transported under controlled conditions. The raw material is inspected, washed and trimmed to remove residual contents, excess fat and unsuitable tissue.
The cleaned gizzards are cut into smaller pieces for even processing. They may be freeze-dried at low temperature or dehydrated under controlled heat, depending on the required nutritional profile, aroma, cost and application.
After drying, the material is milled and passed through a sieve. An 80-mesh powder is commonly supplied, while custom particle sizes can be produced for tablets, capsules, pet food premixes and powdered meal toppers.
The finished powder undergoes metal detection, moisture testing, microbiological analysis and heavy-metal testing. Approved batches are packed in food-grade inner bags and sealed drums. Every lot receives a batch number for production and quality-control traceability.
Typical process flow:
Raw-material inspection → Cleaning and trimming → Cutting → Freeze-drying or dehydration → Milling → Sieving → Metal detection → Laboratory testing → Packing → Final release
Duck Gizzard Powder Applications
Duck Gizzard Powder can be used in pet nutrition, animal supplements and specialty organ-based products. Its concentrated protein, natural mineral content and poultry aroma allow formulators to use it as either a nutritional ingredient or palatability component. Inclusion levels depend on the complete formula, target species and local regulations.
Dog and Cat Food Formulas
Pet Food Toppers and Palatants
Animal Nutrition Supplements
Traditional and Specialty Organ Products
Duck Gizzard Powder for Dogs and Cats
Freeze-dried Duck Gizzard Powder is often used as a single-animal-source pet food ingredient. It can be included in formulas for dogs and cats that require a concentrated poultry protein, a natural organ-meat flavor or a duck-based recipe.
The powder may be supplied as a fine topper, premix ingredient or component of tablets and soft chews. It should be used within a nutritionally complete formula or according to advice from a qualified animal nutrition professional. A single organ ingredient does not provide every nutrient required for long-term feeding.
For pet nutrition projects, Unicorns Biotechnology can control particle size, protein range, fat level, moisture, microbiological limits and packaging format according to the customer’s formulation.
