Emergency throat obstruction!

If feed components or foreign bodies become stuck in the horse's esophagus, the surrounding muscles cramp up and a blockage occurs. Due to the risk of pneumonia caused by inhaling feed residues (aspiration pneumonia), a blockage is always a life-threatening emergency that requires immediate veterinary treatment.

The symptoms of throat obstruction

The first symptoms of throat obstruction can include head shaking, excessive salivation, and coughing. The horse stretches its neck downwards and large amounts of foamy saliva mixed with feed residues are expelled from the mouth and nostrils. If the obstruction persists, circulatory problems, increased breathing rate, and increased sweating may occur. There is a risk that feed residues mixed with saliva may enter the respiratory tract and cause life-threatening pneumonia.

Typical warning signs at a glance:

  • Saliva mixed with feed residue coming out of the mouth and/or nostrils
  • Cramped, stretched head and neck posture
  • Head shaking, pawing with the hooves
  • Gagging noises, coughing
  • Refusal to eat
  • Restlessness, nervousness, panic
  • Increased breathing rate
  • Sweating

Possible causes

Good intentions are not always good. Horse owners who constantly reward their horses with food are not always doing the right thing. Horses that are very greedy and gobble their food should be fed with care. Leftovers from food eaten hastily, small pieces of carrots or beet pulp that has not been pre-soaked can get stuck in the horse's throat. The horse's esophagus is a long muscular tube that transports food from the larynx to the stomach through muscle contractions. If a piece of food that has been swallowed too hastily gets stuck here, the muscles work even harder to move this lump further along. This causes severe cramping of the muscles, which leads to a blockage of the esophagus. If this piece of food also presses on the windpipe, the horse will also cough.

Treatment

If you suspect a blockage in the throat, always call a veterinarian immediately so that they can treat it correctly. Until the veterinarian arrives, the horse can be moved carefully at a walk if it allows.

After a thorough examination and diagnosis by the veterinarian, medication may be administered and a nasal-pharyngeal probe may be used to check the patency of the esophagus. Before inserting the tube, antispasmodic and pain-relieving medication is administered to relax the muscles. A mild sedative also helps to calm the horse and makes it easier for the veterinarian to insert the nasogastric tube, which can be used to flush the esophagus. The veterinarian will attempt to dissolve the stuck food and transport it further into the stomach. If this is not successful, the horse must be taken to a clinic immediately. There, the obstruction can be surgically removed in an emergency and the horse can receive intensive care afterwards.

Tips for prevention

If you know that your horse tends to gobble its food, measure out its feed more carefully and follow these tips to minimize the risk of choking:

  • Only use feed and treats that are specifically designed for horses
  • Always feed roughage before concentrated feed
  • Only feed well-soaked beet pulp
  • Put signs on pastures to prevent uncontrolled feeding
  • Ensure peace and quiet during feeding (avoid feed envy)
  • Do NOT cut carrots, apples, or other fruits or vegetables into pieces; feed them whole

If you suspect that your animal is exhibiting unusual eating behavior for medical reasons, please consult your veterinarian and have your horse examined.
