2018 ACVIM Forum Research Abstract Program: Seattle, Washington, June 14 - 15, 2018

Four commercial extruded diets containing different carbohydrate sources were tested. The diets were classified based on the type of carbohydrate sources they contained: traditional grains (corn, wheat), whole grains (oats, rye, barley), grain-free (peas, lentils, chickpeas) or vegan (no animal ingredients). Each diet was tested once in eleven healthy adult Siberian Huskies and the control (50% glucose solution) was tested twice per dog in a randomized cross-over design. Each meal and control provided 25g of available carbohydrate. Pre-and postprandial blood samples at 15, 30, 45, 60, 90, and 120 minutes were collected to measure whole blood glucose concentrations using a handheld blood glucose monitor. Serum insulin, ghrelin, gastric inhibitory polypeptide (GIP), glucagon-like peptide 1 (GLP-1), leptin, total peptide tyrosine-tyrosine (PYY), and pancreatic polypeptide (PP) concentrations were also analysed at these time points using a magnetic bead multiplex assay.
