Comparative metagenomic and metatranscriptomic analyses reveal the role of the gayal rumen and hindgut microbiome in high-efficiency lignocellulose degradation.

ABSTRACT:

Background

The gayal (Bos frontalis), a semi-domesticated bovine species, demonstrates exceptional adaptability to lignocellulose-rich diets dominated by bamboo, suggesting the presence of a specialized gastrointestinal microbiome. However, the functional mechanisms underlying this host-microbiome interaction remain poorly understood. Here, we conducted integrated metagenomic and metatranscriptomic analyses of rumen, cecum, and colon digesta from yellow cattle and gayal raised on the same bamboo-based high-fiber diet.

Results

The results showed that gayal exhibited superior fiber-degrading capacity relative to yellow cattle, evidenced by significantly higher (P < 0.05) fiber digestibility, cellulase and xylanase activities, and increased volatile fatty acids production despi
