The fecal metabolomic signature of a plant-based (vegan) diet compared to an animal-based diet in healthy adult client-owned dogs
Abstract
Abstract Despite the rising popularity of plant-based (vegan) diets for dogs, the metabolic effects of plant-based diets in dogs have not been thoroughly investigated. Evaluating the impact of a vegan diet on the fecal metabolome in dogs could offer valuable insight into the effects on gastrointestinal and overall health. This study evaluated the fecal metabolic signature of an experimental extruded vegan diet (PLANT) compared to a commercial extruded animal-based diet (MEAT) in healthy adult dogs. Sixty-one client-owned healthy adult dogs completed a randomized, double-blinded longitudinal study consisting of a 4-wk acclimation period, where all dogs received the MEAT diet, followed by a 12-wk experimental period where they either continued with the MEAT diet or switched to the PLANT diet. Fecal collections occurred at baseline (after 4-wk acclimation) and exit (after the experimental period). Fecal metabolites were quantified using 1H nuclear magnetic resonance spectroscopy. Multiple mixed model gamma linear regression was used to evaluate the association of metabolite concentration against age, sex, and body weight, along with an interaction between diet and time. Sixty-six metabolites were quantified. Only 2/66 metabolites differed between groups at baseline and within the MEAT diet group over time. In contrast, 46/66 metabolites differed in concentrations over time in response to feeding the PLANT diet. At the exit time-point, dogs fed the PLANT diet had increased…
