The administration of probiotic E. faecalis or E. faecalis, B. fragilis, and L. salivarius, as a blend, partially improved the performance of chickens, counteracting the antinutritional effects induced by a challenging diet rich in NSPs. The probiotic blend administered during the first days posthatch induced similar beneficial effects on FCR compared to antibiotic group or animals fed probiotic blend during the entire the trial, demonstrating that the administration of probiotics may not be necessary during the entire productive life. Furthermore, the shifted microbiota composition observed at 7 d but not at 21 d indicates an opened window to modify the microbiota populations during the first week of life with direct implications on performance at the end of the poultry productive cycle.
