  • Severe oedema of the throat region.
  • Difficultly in breathing , animal produces a grunting sound.
  • Animal usually dies within 1-2 days of showing symptoms.
  • Buffaloes are generally more susceptible than cattle.
  • Animals with clinical signs, particularly buffalo, rarely recover.
  • In endemic areas, most deaths seen in older calves and young adults.



  • Segregate the sick animal from healthy ones and avoid contamination of feed, fod­der and water.
  • Avoid crowding especially during wet seasons.
  • Vaccinate all animals which are 6 months and above of age annually before the on­set of monsoon in endemic areas.
