Comparison of the guaranteed analysis with the measured nutrient composition of commercial pet foods

摘要: Objective—To compare guaranteed and measured concentrations of nutrients in commercial pet foods. Design—Cross-sectional study. Sample Population—Annual inspection reports food analyses from 5 states. Procedures—Guaranteed crude protein (CP), fat (CF), fiber (CFb), moisture, ash foods were compared. The concentration difference for each nutrient was compared among types food, target species, life stages, manufacturers, laboratories. Results—The significantly different. For all foods, mean differences as follows: CP, 1.5%; CF, 1.0%; CFb, −0.7%; −4.0%; ash, −0.5%. Crude treats larger than dry canned less treats. moisture ...
