Bovine neonatal diarrhea was caused by lactose intolerance due to lactase deficiency. Treating whole milk with lactase alleviated calf diarrhea, suggesting a viable therapeutic approach for this condition.

Area of Science:

  • Veterinary Medicine
  • Animal Physiology
  • Biochemistry

Background:

  • Neonatal calf diarrhea is a significant concern in livestock production.
  • Lactose intolerance, while common in humans, is rarely documented in animals.
  • Understanding digestive disorders in calves is crucial for animal health and welfare.

Purpose of the Study:

  • To identify the underlying cause of neonatal diarrhea in a cohort of calves.
  • To investigate carbohydrate absorption profiles in affected calves.
  • To evaluate the efficacy of lactase treatment for alleviating bovine lactose intolerance.

Main Methods:

  • Oral glucose, xylose, and lactose absorption tests were performed on affected calves.
  • Calves were assessed for clinical signs of diarrhea.

Related Experiment Videos

  • Affected calves were treated with whole milk supplemented with lactase enzyme.

    • Main Results:

    • Calves exhibited normal glucose and xylose absorption but reduced lactose absorption.
    • Lactase deficiency was identified as the cause of lactose intolerance and subsequent diarrhea.
    • Treatment with lactase-treated milk successfully alleviated diarrhea in affected calves.

    Conclusions:

    • Lactose intolerance, resulting from lactase deficiency, is a cause of neonatal calf diarrhea.
    • Oral lactase supplementation presents a potential therapeutic strategy for bovine lactose intolerance.
    • Further research into animal-specific lactase deficiencies is warranted.
