Composition of the rumen microbiome and its association with methane yield in dairy cattle raised in tropical conditions.

ABSTRACT:

Background

Methane (CH₄) emissions from rumen fermentation are a significant contributor to global warming. Cattle with high CH₄ emissions tend to exhibit lower efficiency in milk and meat production, as CH₄ production represents a loss of the gross energy ingested by the animal. The objective of this study was to investigate the taxonomic and functional composition of the rumen microbiome associated with methane yield phenotype in dairy cattle raised in tropical areas.

Methods and results

Twenty-two Girolando (F1 Holstein x Gyr) heifers were classified based on their methane yield (g CH₄ / kg dry matter intake (DMI)) as High CH₄ yield and Low CH₄ yield. Rumen contents were collected and analyzed using amplico
