Two experiments were conducted using direct method to determine the standardized ileal phosphorus (P) digestibility coefficient (SIPDC) of meat and bone meal (MBM) poultry byproduct (PBM) for broilers. In first experiment, three MBM from different batches evaluated, with four treatments (MBMI, MBMII, MBMIII, a P-free diet) nine replicates seven birds each, totaling 252 distributed across comple...

A total of 384 day-old male Ross 308 broiler chicks were allocated to 8 dietary treatments to examine the influence of supplementation with xylanase and phytase, individually or in combination, in diets based on two new cultivars of triticale (Bogong and Canobolas). The inclusion of phytase alone in either Bogong or Canobolas diets increased (P < 0.01) feed intake and body weight; however, the ...

phytate in poultry rations containing rice bran (rb) critically reduce poultry performance while increasing n and p excretion. the objective of this study was to determine whether the anti-nutritive problems associated with higher inclusions of rice bran in poultry rations (up to 40%) could be mitigated with mega doses of phytase. twenty days old male broiler chicks (n=180) in 60 floor pens wer...
