Effects of a nanostructure of phytic acid absorber on the performance and protein digestibility in laying hens

A ten-week experiment was conducted to study the effect of a nanostructure of phytic acid absorber (NPAA) on the performance and protein digestibility in laying hens. A total of 100 Bovans laying hens were randomly assigned to 5 treatments, with 4 replicates, 5 hens each. The experiment was a completely randomized design with 5 levels of NPAA; including zero (T1, as a basal diet (BD)); T2 (BD 0.5% NPAA); T3 (BD 0.25% NPAA); T4 (BD 0.0625% NPAA) and T5 (BD 0.03125% NPAA of total P) in diet. Water and feed were offered ad libitum. Inclusion of NPAA to the diet had significant effects (P
