Thiamine participates in the regulation of ruminal carbohydrate metabolism in ruminants and plays an important role in maintaining rumen health.High intake of non-fibrous carbohydrates by ruminants can easily induce disturbances in the ruminal environment,significantly reducing the ability of rumen microorganisms to synthesize thiamine and causing a functional thiamine deficiency,thereby triggering or exacerbating subacute ruminal acidosis.This article reviews the metabolic pathways of thiamine in the rumen of ruminants and elaborates on the mechanisms by which thiamine alleviates subacute ruminal acidosis through regulating carbohydrate metabolism,optimizing microbial community structure,and maintaining ruminal epithelial integrity,aiming to provide a reference for the pathways by which thiamine mitigates subacute ruminal acidosis.
