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 diet with Mj], each consisting of four replicates (10 birds per replicate) for a 3-weeks feeding period. Feed intake was recorded daily from day 1-21, whereas broilers were weighted at day 1, 7, 14, and 21. Total excreta were collected at day 11-13 and 18-20. At day 21, twelve broilers from each treatment group were slaughtered to collect plasma and tibia. The results showed that Mj significantly enhanced broilers’ live weight and feed conversion ratio compared to the control groups (p |
