Give the sheep an injection. What if the sheep move around?

After the sheep is caught, people ride on the back of the sheep, clamp the forelimbs of the sheep with their legs and fix them, so that the sheep will stop moving and can give the sheep an injection. There are generally three injection methods.

intramuscular injection

At the neck 1/3 (the leading edge of scapula) of mutton sheep, iodine was used for local disinfection. When injecting, press the muscles with the thumb and forefinger of the left hand in a figure of eight, and then push the liquid medicine. After the injection, pull out the needle and disinfect the pinhole with iodine.

Subcutaneous/subcutaneous injection

Sterilize the sheep's neck with iodine first, pull the skin up into a triangular wrinkle with the left hand, and insert the needle into the skin with the right hand. If the needle can move freely from left to right, you can push the liquid medicine. Pull out the needle after injection and disinfect the pinhole with iodine.

main line

The intravenous injection site is the ear or neck of the sheep. Cut off the wool at the injection site, disinfect it with iodine, pat the vein with your hand, pierce the needle into the blood vessel and push it horizontally. If there is blood flowing back into the tube, you can slowly push the liquid medicine and disinfect the pinhole after injection. Intravenous injection is widely used to drive blood protozoa. Because most of its drugs are toxic and irritating, improper injection often leads to local necrosis or even death of sheep, so that some grass-roots veterinarians dare not accept the treatment of blood protozoa.

Pay attention to the following three points when injecting mutton sheep: First, the injection should be diluted as required, and each mutton sheep should be diluted with about 20 ml of 5% glucose solution; The second is to choose a good injection needle; The third is to strictly control the dosage.
