Phaseolus vulgaris Straw as a Substitute for Clover Hay in Rabbit Diets with Prebiotic Supplementation and Feed Restriction Interaction: Influence on Nutrient Utilization, Caecal Activity, Carcass Yield and Blood Plasma Constituents

摘要: Phaseouls vulgaris is one of the most important leguminous crops cultivated in Egypt. It rich protein, dietary fibers, vitamins (A, B1, B & C), minerals (Ca, P, Fe, K, Mg Mn) with high amino acids. Nutrient utilization, caecal fermentative and microbial activity, carcass yield blood plasma constituents 54 weaned NZW rabbits were investigated this study. These parameters evaluated under conditions Phaseolus Vulgaris straw (PS) a substitute clover hay prebiotic (Mannan oligosaccharides, MOS) supplementation feed restriction interaction. For purpose, six-weeks old randomly assigned into six groups (9 rabbits/ group) reared metallic batteries similar conditions. Six pelleted diets formulated as following; control 1 3 (basal diet 100% hay), 2 4 (100% vulgaris, PS substitutive 5 supplemented prebiotic; mannan oligosaccharids, 6 MOS). Feed was achieved by reducing daily intake 30% 3, 4, 6. Results showed that had no adverse effect on measured data. Rabbits subjected to exhibited significant decrease (P 0.05) nutrient digestibility, pH values, load stress hormonal levels T3 cortisol. Meanwhile, MOS restored digestibility nutritive values level ones supported detrimental influence other measurements. Therefore, can safely be for growing inclusion rabbit recommended.
