Dairy cows should not use any drugs during the lactation period. When they must use drugs, they should choose Chinese herbal medicines for treatment. Milk during the drug residue period should not be sold as commercial milk, and milk withdrawals should be accurately calculated before drug withdrawal. Hormonal drugs and antibiotics that are not approved for use by the relevant authorities cannot be used. There are four techniques to be taken when administering drugs to cows.
First, direct oral administration. For powders, tablets, or pills that are small in amount and have little irritation to the mouth, they can be administered directly through the mouth. When taking drugs, raise the cow's head and pull out the tongue from his mouth. Then, send the medicine to the back of the tongue and release the tongue. The medicine is swallowed by the cow.
Second, the medicine bottle injection. Potting bottles are best for rubber and can also be replaced by universal bottles. First fix the cows in the column, fill the medicine bottle with medicine, raise the cow's head, insert the mouth of the irrigation bottle into the oral cavity from the mouth of the mouth, and then pour the medicine into the mouth of the cow several times until the cows are ready. After swallowing the first mouth naturally, inject the second mouth again to avoid coughing. Do not pull the tongue when pouring medicine to prevent swallowing and causing accidental swallowing.
Third, stomach tube administration. The instruments used were gastric catheters and funnels. Before cleaning, inspect the stomach tube and insert it with paraffin oil or water.
1, oral administration of gastric tube administration method. After opening the mouth of the cow with an opener, send it into the mouth of the cow with a hard texture of the stomach tube and insert it along the back of the tongue. After the front end of the stomach tube is pressed against the throat of the cow, resistance can be felt. The stomach tube is swallowed by the cow. While homeopathy is inserted. The correct insertion of the gastric catheter into the esophagus was as follows: there was no flow of bovine respiration from the stomach catheter; cattle did not cough; there was occasional acid odor gas in the tube and a blistering sound. When it is determined that the gastric tube is inserted into the esophagus, insert it again into a 50-70 cm tube, connect the funnel, and pour the liquid into the tube.
2, by intranasal insertion of gastric tube administration method. The practitioners stood on the right side of the cow's head, grasped the cow's left alar with his left thumb, forefinger and middle finger, inserted the catheter end into the left nostril with his right hand, and gripped the catheter with his middle finger and index finger to prevent the catheter from coming out of the nostrils. . Slowly insert the gastric tube into the deep part of the nasal cavity. When the tube end reaches the pharynx, there will be resistance. At this time, the catheter can be pushed back and forth. When the cow produces a hypopharyngeal movement, it pushes the catheter into the esophagus. Insert 20 to 30 centimeters until it is confirmed that no lungs have been inserted. Fill the funnel with liquid medicine. At the end of the irrigation, the residual drug in the stomach tube is blown into the stomach, and the end of the stomach tube is pinched, and the gastric tube is gradually drawn out.
Fourth, elixir dosing method. It is to add a proper amount of flour, wheat bran, etc. into a paste or a tincture, and apply it to the base of the cow's tongue so that the cow can gradually feed and swallow. If necessary, a small amount of water can be fed.
