Protein Level in Maggot

A meta-analysis evaluated the effect of substrate protein level on nutrient composition, macromineral content, and amino acid profiles of maggot. Data were compiled from studies indexed in Scopus over the past decade and synthesized using a mixed-model approach, with substrate protein level treated as a fixed factor and individual studies as a random factor.

Data screening and selection followed the PRISMA-P framework. Higher protein levels in the substrate significantly increased (p < 0.05) dry matter content while reducing neutral detergent fiber in maggot biomass. In contrast, macromineral concentrations remained unaffected.
