Abstract
The objective of the present study was to evaluate the impact of various levels of phytase derived from Bacillus sp. (HCYL03) in corn-soy diets fed to broilers. Experimental treatments included a positive control (PC) with a calculated non-phytate phosphorus (nPP) level of 4.0g/kg for the 35 days of trial. The negative control (NC) diet included a reduction in nPP to 3.0g/kg during the experiment, and commercially available phytase (@500FTU/kg), as well as new bacterial phytase added to the NC diet in increasing amounts of 500, 800, and 1100FTU/kg. Treatment effects on growth performance, the apparent digestibility of P, tibia mineralization, and Ca and P status in blood plasma were evaluated on day 35. The NC diet decreased feed intake (P
