Variations in rumen microbiota and host genome impacted feed efficiency in goat breeds.

ABSTRACT:

Introduction

Improving feed efficiency (FE) is a significant goal in animal breeding programs. Variations in FE and its relationship with rumen microbiota remain poorly understood across different goat breeds.

Methods

This study assessed the influence of the rumen microbiome and host genome on FE in 10 Shami (SH) goats and 10 Zaraibi (ZA) goats, all of which were fed the same diet. The animals were genotyped using the Illumina 65KSNP chip arrays v2, and their rumen bacteria and archaea were investigated using PCR-amplicon sequencing of the 16S rRNA gene.

Results

The results showed that the ZA goats exhibited higher FE than the SH goats (p < 0.05) and a greater relative abundance (p < 0.05) of rumen bacterial groups that are involved in the degrada
