Abstract

The current study was carried out to investigate the effect of native fungal and bacterial recombinant Phytase enzymes produced in lab with commercial sample on performance, growth parameters, Ca and P using 200 day-old Ross 308 broiler chicken which assigned in a completely randomized design to five treatments with four replicates. The experimental treatments included T1: control diet (without enzyme), T2: control diet+commercial phystase enzyme of Nataphus, T3: control diet+Bacillus subtilis enzyme, T4: control diet + E. coli enzyme and T5: control diet+Aspergillus niger enzyme. The results of this study showed that the addition of enzyme to diets decreased feed intake in grower, finishing and total period (P<0. 05). Feed conversion ratio was improved due to the addition of phytase to diets in all periods (P<0. 05). Time and weight at inflation point showed a significant difference between the experimental treatments and control group (P<0. 05). The highest concentration of blood phosphorus at 21 days of age was observed in the group consumed commercial enzyme (P<0. 05). But the amount of phosphorus and bone ash content significantly affected by the enzymes consumed (P<0. 05). Overall, the addition of Phytase enzyme to diets improved the feed conversion ratio and decreased feed intake compared to control group, and no significant difference was observed between commercial enzymes and enzymes produced.
