This analysis investigates how phytase supplementation and phosphorus levels affect eggshell quality in laying hens.
Conducted a meta-analysis of 16 scientific articles published between 2021 and 2025.
Compared diets with adequate phosphorus levels, phosphorus-deficient diets, and diets supplemented with phytase.
Equally assessed the effects of phytase from different origins and various dosages (up to 1,000 FTU/kg).
Phosphorus deficiency reduced shell thickness by 3.50 µm and shell breaking strength by 0.23 kgf.
Phytase supplementation improved shell thickness by 3.14 µm and shell breaking strength by 0.20 kgf compared to phosphorus-deficient diets.
Efficacy of phytase remained consistent regardless of enzyme origin or dosage.
