| Summary | A university trial at Universidad Politécnica de Madrid compared both the prebiotic and postbiotic forms of Aspergillus oryzae in Lohmann Brown Classic laying hens from 15 to 43 weeks of age. AO supplementation significantly reduced the incidence of shell-less eggs across the full trial, while the postbiotic form showed early-stage improvements in egg production (+9%) and feed efficiency (+8%) during weeks 15–21. Results suggest AO-based additives support eggshell integrity and early-cycle productivity in laying hens. |
