PSXI-8 Evaluation of Nutrient Composition and Protein Quality Using the Precision fed Cecectomized Rooster Assay of Novel Avian Protein Sources for pet Nutrition

Abstract Alternative protein sources are being incorporated in companion animal diets as a response to the market demand for high quality products. Chicken is commonly used pet food and was comparison emerging alternatives goose, quail, duck, emu which have been evaluated current study. All were analyzed chemical composition, amino acid (AA) standardized digestibility calculation of digestible indispensable scores (DIAAS-like) determined by using precision fed cecectomized rooster assay. Dry matter values ranged from 95% 98% similar all proteins. Crude least goose meat greatest (42% 95%, respectively). Emu produced fat content while quail most (4.7% 42%, Standardized AA novel proteins above 60% AA. The DIAAS-like applied reference based on Association American Feed Control officials (AAFCO) recommended nutrient profile National Research Council (NRC) allowances adult dogs cats at maintenance. AAFCO NRC >100%. Tryptophan identified be first-limiting every source except where methionine dogs.
