Acidosis / SARA

What is it?

Sub-acute ruminal acidosis (SARA) occurs when cows are fed high-energy, low-fibre diets, typically during early lactation. Prolonged low rumen pH reduces ruminal function, decreases feed intake, and impairs overall health.

Symptoms

  • Reduced feed intake
  • Slow eating
  • Decreased milk yield and butterfat content
  • Loose manure with undigested grain
  • Discomfort, kicking at the stomach, restlessness
  • Increased lameness
