چکیده
Abstract Given the dynamic market for protein-based ingredients in pet food industry, demand continues to increase both plant- and animal-based options. Animal plant protein sources contain different amino acid profiles vary digestibility, which can affect quality provided animal. Our objective was evaluate apparent total tract digestibility (ATTD) compare of canine diets differing source using healthy adult dogs. Four isocaloric isonitrogenous, extruded were formulated meet all AAFCO nutrient recommendations dogs, with primary difference being source: 1) chicken by-product meal (CBPM), 2) deboned chicken, dried spray (DC), 3) corn gluten (CGM), or 4) wheat (WGM). Adult female beagles (n = 20; BW 9.9 kg; age 6.3 yr) used a replicated 4×4 Latin square design (n=12/treatment). Each period consisted 22-d adaptation phase, 5 d fresh fecal collection, 1 blood collection. All data analyzed Mixed Models procedure SAS 9.4. Diets contained similar crude (CP) concentrations (39.8%-41.7%), but DC had most balanced AA profile (indispensable AA:dispensable ratio). Fecal scores greater (P< 0.01) dogs fed CBPM than those WGM CGM, remained within an appropriate range. Apparent dry matter less 0.0001) CGM WGM. Dogs decreased organic matter, CP, energy digestibilities other 3 diets. CP also reduced Considering together, diet clearly greatest tested.
