Age-related gut microbiota succession in Neijiang pigs: insights for precision feeding and productivity.

ABSTRACT:

Objective

To characterize age-related gut microbiota succession in Neijiang pigs and translate these dynamics into actionable insights for precision feeding and productivity improvement.

Methods

Growth data from 0 to 180 days (n = 16, 780 weight records) were fitted with three non-linear models to determine the optimal growth curve and partition physiological stages. Fresh feces were collected at 25, 70, 110, and 150 days (n = 6/stage). 16S rRNA V3-V4 amplicon sequencing was used to profile microbiota composition and diversity; PICRUSt2 was employed to predict metagenome functions against the KEGG database.

Results

The Gompertz model best described growth (R ² = 0.996) with an inflection point at 84.2 days (25.9 kg). Microbial alpha-div
