The biogeography of gastrointestinal mucosal microbiota of beef cattle at harvest.

ABSTRACT:

Introduction

The gastrointestinal microbiota profoundly influences the health and productivity of animals. This study aimed to characterize microbial community structures of the mouth, gastrointestinal tract (GIT), and feces of cattle.

Methods

Samples were collected from 18 Akaushi crossbred steers at harvest from multiple locations, including the oral cavity, rumen, abomasum, duodenum, jejunum, ileum, cecum, spiral colon, distal colon, and feces. These cattle were raised without exposure to antimicrobial drugs or hormone implants. Total microbial abundance was assessed using qPCR targeting the V3-V4 region of the 16S rRNA gene, and microbial community composition was evaluated through 16S rRNA gene sequencing.

Results

Total microbial abundance was lesser in the small
