Chemical composition, protein quality, palatability, and digestibility of alternative protein sources for dogs.

摘要: The chemical composition and protein quality of 11 alternative sources (chicken products, blood enzyme-hydrolyzed fish concentrate, soybean meal, spray-dried pork liver) were determined, an experiment was conducted to determine palatability digestibility processed red cell-containing diets. Chicken differed in concentrations CP, acid-hydrolyzed fat, total AA (TAA) by 20, 31, 24%, respectively, GE 1.7 kcal/g. Blood varied little fat concentrations, but CP TAA 8%, respectively. Protein solubility chicken source categories averaged 57 69%, liver 53, 67, 26%, Based on calculations from immobilized digestive enzyme assay values, lysine approximately 80.4 81.7% for sources, Lysine values meal 89 77%, A chick efficiency ratio (PER) showed that had high as the PER ranged 2.7 5.3, whereas poor (PER less than 1.5). Enzyme-hydrolyzed liver, greater 2.8). In dog experiments, a corn chicken-based diet supplemented with either 0 or 3% cells tested. test dogs consumed more contained 0% vs. cells. intake 0.34. Nutrient digestibilities did not differ, except where (P = 0.01) consuming diet. These data suggest differ greatly among ingredients within same category. Palatability cells-containing is highly palatable but, when this offered only one food, demonstrated no aversion response some decrease digestion.
