Sodium butyrate reduces inflammation signaling in the milk-producing glands of goats during mild rumen acidosis

Abstract

A pH value < 5.8 sustained for more than 3 hours per day confirms subacute ruminal acidosis (SARA) in goats on a high-concentrate diet.

  • A high-concentrate diet may induce SARA in mid-lactating goats by lowering rumen pH.
  • Goats receiving the high-concentrate diet with sodium butyrate showed lower levels of lipopolysaccharides (LPS) in their blood compared to those on the regular high-concentrate diet.
  • The group treated with sodium butyrate had significantly reduced levels of proinflammatory cytokines in their blood.
  • Decreased expression of immune response-related genes (NOD1, IKβ, and NF-κB) was observed in the mammary glands of goats treated with sodium butyrate.
  • Oral sodium butyrate supplementation may inhibit the NOD1/NF-κB inflammatory pathway linked to mammary inflammation.
