Soluble lipopolysaccharide concentrations in caecal digesta but not ruminal digesta correlatewith inflammation of rumen wall tissue at slaughter in commercial beef cattle at risk of SARA

摘要

Implications Caecal soluble lipopolysaccharide (LPS) concentrations were found to be much higher than those found inthe rumen. Caecal LPS and not ruminal LPS concentrations correlated with visible inflammation of the rumen wall. Thus,some of the inflammation associated with sub-acute ruminal acidosis (SARA) may actually originate in the lower gut.
