ABSTRACT The finisher phase (22 to 42 days post-hatching) is a critical period in broiler production due to its high feed consumption and growth rate. This study performed a systematic review and meta-analysis of 21 peer-reviewed articles, comprising data from 10,706 male broilers aged 22 to 42 days, to quantify the effects of phytase (PHY) supplementation during this critical phase. A mixed-effects model was used to assess the impacts of PHY, dietary non-phytate phosphorus (NPP), and the calcium to non-phytate […]
