Probiotics and phytobiotics have demonstrated effective improvement of gut health in broiler chickens when individually administered in-ovo. However, their combined use in-ovo, has not been studied to date. We coined the term "prophybiotic" (probiotic + phytobiotic) for such a combination. The current study therefore, aimed elucidate effects selected probiotic phytobiotic on production parameters, as opposed probiotics alone. ROSS 308 hatching eggs were injected with either Leuconostoc mesenteroides (probiotic: PB) or garlic aqueous extract (prophyiotic: PPB) 12th day incubation. Relative abundances bacteria feces cecal content (qPCR), immune related gene expression mucosa (qPCR) histomorphology tissue (PAS staining) analyzed along parameters (hatch quality, body weight, feed efficiency slaughter meat quality). PPB treatment increased abundance faecalibacteria bifidobacteria (d 7) Akkermansia sp. content. Moreover, it decreased E. coli both 34) PB only resulted up-regulation genes (Avian beta defensing 1, Free fatty acid receptor 2 Mucin 6) crypt depth ceca whereas higher tendency increase 6 expression. Both treatments did impair studied. In conclusion, our results suggest that in-ovo prophybiotic may enhanced potential boosting system without compromising efficiency, compared Our study, highlights carefully combinations better improving chickens.
