What makes the protein bio-available and what effect does the amino acid profile have on protein quality?
In general, two components make up the “quality” of a protein: 1) digestibility and 2) amino acid profile. The protein sources in both of these supplements are highly digestible by the canine digestive tract, which makes them highly bio-available. If an animal cannot digest a protein source, it will simply pass the protein through the digestive tract. Protein quality is also related to amino acid profile. Different animals need different quantities of essential amino acids-a protein source that is excellent for one species may have an inappropriate digestibility or amino acid profile for another. The protein sources (casein, dried whole egg, and liver) have been balanced with the free form amino acids dl-Methionine, l-Lysine, and Taurine (Coat & Skin Formula) to provide superior digestibility and amino acid profiles for the canine species.
