duck liver
Duck liver keeps duck recipes single-species while adding organ nutrition. How Bowlmark scores named organs.
What it is
Duck liver is the liver of ducks — the organ component of duck-first and novel-protein formulas. Nutritionally it is liver: vitamin A, B vitamins, iron, and dense protein.
Why it's in pet food
Limited-ingredient duck recipes want every animal ingredient to be duck, and duck liver covers the organ slot. Its inclusion is usually modest and deliberate — position on the label tells you the dose.
How Bowlmark scores it
Scores are deterministic math over the printed label — the rules below apply to every product identically, and nothing estimates or fills in a blank.
Duck liver is a named protein source to the engine — the word "duck" is what it reads. When it is the first ingredient it earns the 15-point fresh named-protein bonus on the ingredient-quality pillar; in any other slot it earns nothing, because only named meals score in the second and third slots. No deduction applies — an organ sold under its own name is the transparent version of what "by-product" hides.
