Cellulase activity and age-based variation of intestinal microbiota in Hezuo pigs.

ABSTRACT:

Introduction

To examine the fiber-degrading enzyme activity and the changes of intestinal microbiota in Hezuo pigs across different age stages.

Methods

Fecal samples from 36 semi-grazed Hezuo pigs across five growth stages were collected for cellulase activity and 16S rRNA gene sequencing analysis.

Results

The results showed that the cellobiase activity in adult Hezuo pigs was markedly higher than in other groups (p < 0.01). The intestinal microbiota of Hezuo pigs was predominantly composed of Firmicutes and Bacteroidetes. The prevalence of Proteobacteria of nursing piglets was significantly higher compared to other stages (p < 0.05), which might be related to protein degradation. Prevotella_NK3B31_group was a shared dominant genus across at all a
