Dynamic succession and origin of gut microbiota during early-life in White King pigeon.

ABSTRACT:

Background

The gut microbiota plays a critical role in host health, yet the dynamic establishment and key influencing factors of the early-life gut microbiota in pigeons remain poorly understood.

Methods

This study employed 16 S rRNA gene sequencing to characterize the spatiotemporal succession of gut microbiota in White King pigeon squabs (Within one week after birth) and quantify contributions from potential sources, including pigeon milk, cloaca, egg components, feed, and environment.

Results

Revealed a dramatic transition from prenatal to postnatal microbiota: meconium (G0) was dominated by Pseudomonas (19.6%), Enterococcus 14.5%), and Escherichia-Shigella (8.7%), whereas postnatal communities rapidly shifted to a stable composition dominated by Lactobacillus and
