| ABSTRACT Phytase enzyme is supplemented to poultry feed to improve phosphorus (P) availability. Mitsuokella jalaludinii, bacteria isolated from the rumen of cattle, has been reported as a cheaper alternative source of phytase. As much nutrients are trapped within the phytate complex, we hypothesized that the supplementation of M. jalaludinii phytase to poultry feed would enhance nutrient utilization by poultry. In the current study, the efficacy of freeze-dried M. jalaludinii cells (Mj) as feed supplement for broilers fed low-available phosphorus (low-aP) diet was evaluated. Day-old male Cobb raised in battery cages were assigned to three treatment groups [normal-available phosphorus diet with heat-deactivated Mj (DMj); low-aP diet with DMj; and low-aP... |

| An experiment was conducted to evaluate the effect of an enzyme blend (EB) on the performance, diet metabolizability, phosphorus (P) retention, and bone mineralization of broilers fed diets containing 10% defatted rice bran (DRB). In total, 432 one- to 38-d-old male Cobb broilers were evaluated according to a completely randomized experimental design in 3 x 2 factorial arrangement. Three diets were tested with two nutrient reductions (NR) in the matrix (standard diet; NR I of 75 kcal/kg ME, 0.1% Ca and 0.1% available P; and NR II of 100 kcal/kg ME, 0.1% Ca and 0.1% available P) with or without the addition of an EB (200 g/t). The coefficients of total tract apparent retention (CTTAR) of the diets and P retention were determined by collecting excreta during... |
