Tips for puncturing cattle infusion

Subcutaneous injection, usually on both sides of the neck. When injecting, lift the skin of the cow with one hand, hold the syringe in the other hand and pierce the needle 3-4 cm under the skin, and then inject the liquid medicine. If there is a lot of liquid medicine, multiple injections can be performed at different points. After injection, the needle is pulled out, and then local disinfection is performed with alcohol cotton balls or iodine tincture.

Intramuscular injection, the injection site is usually the buttocks and neck with thick muscles. When injecting, first pierce the needle into the muscle, and then connect the syringe containing the liquid medicine. After the plunger is pulled out to confirm that there is no blood return, the liquid medicine is injected, or the needle is installed to complete the operation at one time. After the injection, the needle is pulled out and disinfected with a cotton ball dipped in alcohol or iodine tincture.

Intravenous injection, the injection site is usually the jugular vein at the junction of the upper third of the neck and the middle third of the neck. When injecting, press your finger on the proximal vein at the injection site. After the blood vessel is bulging, pierce the needle at an angle of 15 to 45 degrees, and continue to push it into the blood vessel for about 1 cm in the direction of the blood vessel when bleeding occurs.

After pushing in the needle, connect the injection hose that purifies the air, lower the syringe, and lift the syringe to the same height as the head of the cow when blood is returning, and the liquid will flow into the vein at this time. After the injection, use the alcohol cotton ball with the left hand to compress the needle hole, quickly pull out the needle with the right hand, and then continue to press the needle hole. After the bleeding is completely stopped, use iodine tincture for disinfection.
