Effect of Reduced Dietary Crude Protein Levels on Growth Performance, Plasma Uric Acid and Electrolyte Concentration of Male Broiler Chicks

摘要: Changes in dietary electrolyte balance influence the metabolic fate of protein and many amino acids. Furthermore, acid-base condition is achieved part by alteration acids pattern quantity. Therefore, a trial was conducted completely randomized design to evaluate performance, carcass characteristics, plasma uric acid concentrations 19 28-day-old male broilers fed three experimental diets which CP decreased stepwise manner from 21 18%. Ileal digestible quantities all EAA were almost equal diets, total amount each maintained at or above NRC 1994 requirements. Decreasing did not affect performance appetite but increased fat deposition whole body abdominal cavity, significantly. High crude chickens generally produced breast, thighs carcasses that lower fat. Reducing main electrolytes including ionized forms (Na + , K Cl - ) its on Ca ++ HCO 3 ions significant. On other hand, concentration reduced parallel with reduction. although reduction 18% does impair broiler chickens, deficiency production low may lead blood imbalance.
