How to prevent esophageal obstruction in dairy cows with foreign bodies in the esophagus

Cows suddenly stop feeding, shake their heads and shrink their necks, dig the ground, arch their backs, salivate a lot, chew empty mouths, and swallow constantly. When the obstruction is in the neck esophagus, the obstruction can be touched by the external hand; when the obstruction is in the chest esophagus, the neck esophagus expands, a large amount of saliva accumulates in the esophagus, and the touch pressure fluctuates.

Cow

1. Preventive measures

Reasonable preparation of forage, regular and quantitative feeding, when feeding root or cottonseed cake feed, should be chopped and then fed, and prevent cows from stealing large pieces of feed. When cows are feeding, they should never be suddenly driven away or frightened.

II. Treatment methods

The treatment of the disease is to quickly remove esophageal obstruction and unobstruct the esophagus. If the cow has been complicated with acute rumen dyspnea, it should be punctured and deflated immediately to prevent the cow from asphyxiation.

1. Extrusion method: squeeze the obstruction outside the esophagus with both hands. When the obstruction is in the esophagus 1 stroke 3, push the lower part of the obstruction so that it runs to the throat, and then quickly pull the obstruction out of the mouth with your hands. When the obstruction is in the middle and lower part of the esophagus, it should be pushed down into the stomach.

two。 Push method: insert the gastric tube, inject 1% procaine 20 ml, liquid paraffin 100 ml, wait 1 minute, push down the gastric tube, push the obstruction into the stomach.

3. Aeration method: when the inserted gastric tube is against the obstruction, connect the outer end of the stomach tube with the pump, pump hard and quickly, every time you pump air, take advantage of the expansion of the esophagus, push the stomach tube down a little bit, generally hit 3 or 5 times until the obstruction is pushed below the original obstruction, you can push the obstruction into the stomach.

4. Washing method: when you encounter the obstruction caused by broken particles, you can use the washing method, that is, pour an appropriate amount of water into the esophagus through the gastric tube, then quickly lower the outer end of the gastric tube, lower the cow's head accordingly, and derive feed particles and operate repeatedly until water can flow into the stomach and dredge the esophagus.

5. Beating method: put the cow lying on his back in Baoding, put a flat plank on the blocked part of the esophagus in the neck, then put the standing plank on the obstructed part (the thickness and width of the plank is slightly larger than the obstructed part with its cross-section, long 50~80cm is appropriate), the assistant beat the top of the upright plank with a pound hammer, you can flatten the obstructed object (smash it), and then squeeze it by hand or push it through the stomach tube or let the cow swallow the obstructed material by itself.

6. Salt method: the obstruction caused by root feed and melons and fruits can be forcibly injected into the esophagus with bare hands (30g to 50g). Through the action of osmotic pressure, the water of the obstruction can be sucked out, so that the blockage volume becomes smaller and the cow can swallow by itself.
