Toward precision phosphorus nutrition in broilers: insights from a meta-analytical model assessment

Key Points

• This research aims to estimate the available phosphorus requirements of broilers through a systematic review and meta-analysis.
• Conducted a systematic review and meta-analysis using data from 90 studies published between 1997 and 2023.
• Utilized databases including PubMed, Scopus, and Web of Science following the PICo methodology.
• Analyzed variables such as average daily gain, feed efficiency, and bone traits relative to performance metrics.
• Identified significant correlations between available phosphorus levels and both average daily gain and feed efficiency.
• Assessed bone traits like tibia phosphorus content and shear force, showing variability in responses across studies.
