Comparative Analysis of Protein Sources in Commercial Dog Foods
I am interested in initiating a comparative discussion regarding the efficacy and bioavailability of various protein sources utilized in commercially available canine diets. Specifically, I would like to gather insights or recent research data comparing traditional animal-based proteins (such as chicken, lamb, beef, and fish) with alternative sources (including hydrolyzed proteins, insect protein, and plant-based proteins like pea and soy).
From a nutritional standpoint, what are the implications for digestibility, amino acid profiles, and allergenicity among these sources? Furthermore, are there quantifiable differences in long-term health outcomes for dogs consuming diets predominantly composed of alternative versus traditional protein sources?
Input from individuals with experience formulating dog diets, as well as those with access to recent peer-reviewed literature on this subject, would be highly valuable.
