Trial  A

Year 2021
Summary During the entire trial period (15 to 43 weeks), AO postbiotic supplementation reduced (P < 0.05) the incidence of shell-less eggs throughout the trial period. In addition, from 15 to 21 wk of age, the feeding of AO increased egg production by 9% and improved FCR by 8%, but the differences were not significant. In conclusion, the inclusion of AO in the diet increases hen performance and eggshell quality.

Trial  B

Year 2022
Summary During the entire trial period from 18 to 41 weeks, supplementation of AO postbiotic improved all major production traits studied, included egg mass (50.6 25 vs. 49.7 g/d) and FCR (2.27 vs. 2.32). During the pre-peak phase (18 to 25 weeks), no differences were observed for any of the production or egg quality traits studied. In the peak production phase (26 to 41 weeks), however, egg mass was greater in hens fed AO than in controls (64.4 vs. 62.7 g/d; P < 0.05). Also in this phase, AO supplementation increased egg production (98.2 vs. 96.6%) and egg weight (65.6 vs. 64.9 g), and improved FCR (1.84 vs. 1.90) but the differences were not significant.
