nutrients react with the environment,
specifically oxygen, moisture and
heat. Adequate stabilization protects
the nutrient from degradation and is
critical to ensuring correct nutrient
levels in the food.
The ingredient "blacklist" seems to
be getting longer and longer which, as
a formulator, is concerning. A current
trend that compounds the issue is the
move away from vitamin and mineral
supplementation. However, this is a
risky proposition as nutrient levels
in ingredients are inherently variable, which may be intensified with
changes in soil quality. When creating
a complete and balanced food that is
potentially going to feed an animal for
its entire life, we need to be absolutely
certain that we are doing our best to
provide all of the essential nutrients
the animal needs.
Let's look at the Association of
American Feed Control Officials
(AAFCO) Dog Food Nutrient Profiles
for Growth and Reproduction and
consider how to meet vitamin and
mineral requirements through whole
foods alone.
For minerals, calcium, phosphorus
and zinc stand out as the greatest
potential challenges. Calcium and
phosphorus are present in animal
protein ingredients, specifically in meat
meals that contain significant quantities of ash (i.e., minerals). Achieving the
correct ratio of these minerals, which
is particularly critical for bone development, may be challenging with ingredients alone. The formulator will likely
need to be very choosy when selecting
the type and amount of each ingredient
to provide the correct total amount and
ratio of calcium and phosphorus.
Providing adequate levels of
zinc from whole food ingredients is
also difficult given that the AAFCO

minimum requirement for growth and
reproduction in dogs is 100 mg/kg.
While oysters are a very rich source of
zinc there are few, if any, other ingredients that will be able to contribute
enough zinc to meet the AAFCO
nutrient profiles for dogs.

When it comes to vitamins, liver is a
rich source of vitamin A, and fatty fish
and cod liver are sources of vitamin D,
but there are not a lot of other options.
Supplementation allows for the
development of many different types of
pet foods with many different ingredients. Not all pets do well with all types
of ingredients. Supplementation allows
for more options in ingredient selection
because ingredients do not need to be
chosen primarily based on the one or
two key nutrients that they provide. This
allows more flexibility for the formulator
and greater ability to customize the
nutrient profile of a product, especially
when formulating therapeutic diets.

How to safely walk the
'clean label' path
With that said, if the desire is to
continue to venture down the "clean
label" path and develop a food with

little or no vitamin/mineral supplementation, what steps should be taken
to do to this as safely as possible?
First, you need to know your
ingredients and supply chain very
well. Ingredients need to be tested
and re-tested for each of the essential
nutrients they are being relied upon
to provide to the formulation and
for which a supplement will not be
included. The inherent variability in
the nutrient must be determined and
accounted for in the formulation. The
final product must also be tested for
levels of all essential nutrients. It's
also important to remember that the
assays used to determine vitamin
levels have variation in their results. In
general, the lower the concentration of
the vitamin, the higher the analytical
variation. With a full nutrient analysis
typically costing several thousand
dollars, this is likely going to be an
expensive, but necessary, process.
Feeding trials are also something
to consider when formulating without
supplementation. For diets without
vitamins and minerals added, it is
much more difficult to ensure that the
product meets the nutrient requirements of an AAFCO-recognized
nutrient profile. While a trial may not
tell you everything you need to know
about how a diet will perform, it will
provide an extra level of reassurance
that a food without supplementation
will perform as intended.
While the vitamin and mineral list
on a pet food can seem a bit daunting,
these are vital components for the
well-being of pets. Instead of taking a
risk and eliminating them, consumers
need to be educated about why supplementation is important. ■
