" The importance of supplying
sufficient quantities of amino acids
(NRC 2006). Phenylalanine is required for protein syn- in dog diets is clearly much more
thesis and for the synthesis of tyrosine, but it also plays
a vital role in the synthesis of catecholamines (such as nuanced than purely supplying
dopamine, epinephrine, and norepinephrine), which are
important to regulate the stress-response (Fernstrom enough dietary protein. "
and Fernstrom 2007). Phenylalanine and tyrosine also
play a role in the maintenance of coat color via production of a compound called eumelanin, a form of
melanin (Biourge and Sergheraert 2002). When blackcoated dogs have a deficiency in phenylalanine and tyrosine in the diet, it can be easily observed as these dogs
will develop a reddish-brown haircoat (Biourge and
Sergheraert 2002). While these are only a few examples
of secondary metabolites synthesized from indispensable AAs, this illustrates that many play an important
role in other vital metabolic processes and often these
are noticeable to the dog owner.
The importance of supplying sufficient quantities of
AAs in dog diets is clearly much more nuanced than
purely supplying enough dietary protein. To ensure diets
are formulated with the intention of promoting health

Crosbie, et al, University of Guelph

and longevity in our pets, it is critical that more attention
is paid to the indispensable AA profile of specific protein
ingredients, the digestibility of these indispensable AAs,
the processing necessary to ensure the protein source is
suitable for diet formulation, and the metabolic role(s)
played by each indispensable AA. In contrast to the information available on other species, such as agricultural
animals, on what variables affect AA requirements, the
information available in dogs and among dog breeds is
sparse. Optimization of protein and AA delivery needs
to be improved to support the long-term sustainability
of the pet food industry.

This is the Way
Gericke is the
way to a uniform,
homogeneous
mix, and fast,
easy, complete
cleaning.
Only Multiflux® GMS mixers from Gericke include a proprietary, double-rotor design for thorough - yet gentle mixing and blending in as little as 30 seconds. To clean, the entire front door opens and the optional, cantilevered
mixing mechanism slides out for 360-degree open access. For high quality results every time, this is the way.
