Ruminal Fermentation, Methanogenic Archaeal Diversity, and Metabolomic Responses to Urochloa brizantha Extracts in Sheep
Background: Phytogenic feed additives are being explored as alternatives to conventional rumen modulators, yet their effects on the ruminal ecosystem remain insufficiently characterized when assessed only through conventional fermentation parameters. This study evaluated the effects of ethanolic and hydroethanolic extr...
