This analysis aims to validate how starch and protein digestive dynamics affect broiler growth performance and the utility of jejunal digestion rates as indicators.
Conducted a meta-analysis of 260 data points from 32 published papers.
Focused on variations in the jejunum regarding starch and protein digestion.
Analyzed the impact of digestion on body weight gain (BWG) and feed conversion ratio (FCR).
Utilized a multiple-level meta-analysis to account for variations between and within studies.
Jejunal digestion showed greater variation in the proximal section compared to distal sections.
Both ileal and jejunal digestibility of starch and protein positively influenced BWG and FCR.
Optimizing starch and protein digestion is critical for maximizing BWG, predicted to be 1703 g/bird at a specific starch to protein ratio.
