Cover Story: The weekly succession patterns of cecal microbiota in Japanese quail (Coturnix japonica) were evaluated by 16S rRNA metabarcoding from 7 to 42 days of age, and evidenced an increase in Firmicutes (from 50% to >80%) and a decrease in Bacteroidota (from 45% to 12%). The microbiota became progressively richer and more balanced with age; genera such as Bacteroides were predominant in the beginning and later were replaced by Lachnospiraceae, Ruminococcus, and Faecalibacterium. The developmental taxonomic features aligned with significant shifts in ten metabolic pathways identified by prediction, revealing a transition from biosynthetic functions to complex carbohydrate metabolism and cell wall biosynthesis. The first 7 days are considered a critical window for probiotic interventions, which may favor the establishment of a microbiota that is more stable and beneficial to quail performance. View this paper
