Prevention and treatment of esophageal obstruction in cattle and horses

The obstruction of esophagus in cattle and horses is the obstruction of feed in lumps or lumps or foreign bodies in the esophagus and cannot descend in the stomach. It is characterized by sudden onset, dysphagia, salivation, reflux, rumen flatulence and so on. The traditional Chinese veterinarian is called hiccup.

1. To remove the obstruction in the esophagus, the following methods can be used: ① extraction from the mouth: if the obstruction is near the pharynx or retropharynx, fix the foreign body, install an army-style mouth opener and press the tongue, reach in and take it out. If the obstruction is hard and smooth in the esophagus of the neck, let the animal lie on the right side, put a plank under the neck, one person squeezes forward along the left esophagus, squeeze the foreign body near the pharynx and fix it, the other person pulls and presses the tongue with his left hand, and the right hand reaches into the mouth to remove it, or move the foreign body onto the wood block and smash it with a mallet with appropriate strength. Or squeeze the foreign body down to make it enter the chest esophagus, and then slowly send it to the rumen with a probe. ② into the rumen method: if smooth and dry hard obstruction in the lower part of the esophagus, close to the cardia, you can first pour 500g koji wine or liquid paraffin or vegetable oil 300ml through the mouth, and then slowly send it into the rumen with a probe; or connect a pump on the gastric tube to pump rhythmically, and use the gastric tube to push the obstruction into the rumen while the esophagus is dilated. If ③ has esophageal spasm, 40ml of 5% procaine solution can be injected into the esophagus, or 250ml of 5% chloral hydrate alcohol can be injected intravenously. ④ was subcutaneously injected with 3% pilocarpine hydrochloride and 3 ml. If the ⑤ is a sharp obstruction, do not force reckless pull, to push, massage, etc., if necessary, esophagotomy to remove the obstruction. If ⑥ is completely blocked and rumen flatulence occurs, rumen puncture and outgassing should be performed to prevent asphyxia. ⑦ should be carefully nursed. If the course of the disease is long, nutrition should be increased. Glucose saline can be injected intravenously with appropriate amount of sodium bicarbonate solution. ⑧ uses bovine emetic. The method is to make a solution of dehydrated morphine hydrochloride 0.1-0.2 and distilled water 5 ml, which is injected subcutaneously once.

two。 Preventive feeding should be fixed and quantitative to avoid excessive muscle hunger of cattle and horses, so as to prevent excessive feeding and swallowing too hard. When eating fodder, try to avoid external interference. It is necessary to adjust the feed reasonably, such as feeding a piece of root feed to be processed and chopped, and the cake to be soaked and broken. Do not graze in lumpy fodder fields, such as raw sweet potatoes, carrots, potatoes, sugar beets and green corn cobs. lump fodder should be kept to prevent cattle and horses from stealing food. Diet should be prohibited during the obstruction period.
