Rumen Acidosis

  • Acidosis may be clinical or sub- clinical.
  • Feeding large quantities of rapidly digestible carbohydrate in a short period of time  causes clinical acidosis.
  • In severe clinical cases, animals may be recumbent within  24-48 hours, which may resemble cases of milk fever. Animal may not urinate or pass dung.
  • Sub-clinical acidosis is seen as a result of feeding increased concentrates compared to forage.
  • In  sub-clinical acidosis there  is reduced feed intake, weight loss, unexplained diarrhoea and exhaustion. This may also lead to laminitis and lameness.
  • In severe clinical  cases, prognosis may not be good. Some animals though appear to improve, may become seriously ill 3-4 days later.



  • Proper feeding practices should be adopted after consulting a veterinarian.
  • Animal should be provided a roughage diet in the mornings before feeding concentrates so that adequate quantities of saliva is produced.
  • Never provide the animal with large quantities of rapidly digestible carbohydrates.
  • A veterinarian must be consulted immediately in case of clinical acidosis.
