Introduction

  • Cause: inherited autosomal recessive trait.
  • Signs: hypersalivation, poor coat, small soft horns, soft feces to diarrhea and failure to thrive.
  • Diagnosis: provisional diagnosis can be made based on the history and clinical presentation.
  • Treatment: no treatment.
  • Prognosis: poor.

Pathogenesis

Etiology

  • The condition is thought to be an inherited autosomal recessive trait.

Predisposing factors

Specific

  • Dam and sire are carrier (heterozygous) animals of the condition.

Pathophysiology

  • It is thought that this condition is caused by a generally lower mitotic rate in tongue epithelium, interfering with the formation of primary dermal papillae.
The condition has been experimentally induced by inducing iron deficiency Iron overview in calves which caused atrophy of the filiform papillae
 

 

Timecourse

  • Present at birth.

Epidemiology

  • Previous studies have investigated the penetrance of the condition within affected herds.
  • Due to the condition being an inherited autosomal recessive trait, it has been demonstrated to occur in 1:3 distribution in the F2 generation.
