Researchers investigate broiler response to phytase enzymes

TUCKER, Ga. — USPOULTRY and the USPOULTRY Foundation announce the completion of a funded research project at Mississippi State University in which researchers investigated broiler response when fed phytase enzymes. The research was made possible in part by an endowing Foundation gift from Peco Foods and is part of the Association’s comprehensive research program encompassing all phases of poultry and egg production and processing. A brief summary of the completed project is shown below. A complete report, along with information on other Association research, may be obtained through USPOULTRY’s website, The project summary is as follows.

Project #F082: Response of Broilers Fed Phytase Enzymes of Different Optimal pH Ranges Alone or in Combination

(Dr. Kelley Wamsley, Mississippi State University, Mississippi State, Mississippi)

Dr. Kelley Wamsley and colleagues at the Mississippi State University Poultry Science Department recently completed a research project that investigated how broilers respond when fed phytase enzymes of different optimal pH ranges alone or in combination. Overall data did not signify that feeding multiple phytase enzymes will contribute to significant improvements for the commercial broiler industry. However, findings did suggest that more attention towards calcium and available phosphorus ratios can further the efficacy of phytases.
