How do you give a pig an injection

The following should be done when giving injections to pigs:

(1) Correct selection of needles

Generally sick pigs should be injected with a 12-gauge long needle, because the long needle injection is deeper, the liquid medicine can fully enter the muscle tissue. If a small needle is used, the injection is shallow and the drug solution is not well absorbed and used, and it is easy to flow out of the needle eye.

(2) Baoding good pig

When injecting, make sure the pig has at least one other person to help hold the head in place so the pig doesn't wiggle, bend or break the needle.

(3) The injection speed should be slow

In the case of someone holding the pig's head, to slowly inject, slowly push the drug, so that the liquid in the muscle tissue gradually spread. Someone IS used to inject the needle into the injection site after the very quick push liquid medicine, such can make liquid medicine concentrated in local only, need a long time to dissipate absorption, thereby affecting the effect of the timely play.

(4) Disinfection before injection

Before injection, the injection site should be sterilized with alcohol or iodine tincture cotton ball. During disinfection, the disinfection cotton ball should be wiped from the inside out to the disinfection site. After injection, hold the needle eye for 1-2 min with a sterilized cotton ball, which can make the drug liquid spread better in the muscle and prevent overflow, so as to improve the efficacy and therapeutic effect.

Giving pigs injections is the main way to prevent and treat swine diseases. Commonly used are intramuscular injection, subcutaneous injection, intravenous injection, intraperitoneal injection and other methods of injection.

intramuscular

The blood vessels in the muscle are rich, and the medicine liquid injected is absorbed faster. In addition, the sensory nerves in the muscle are less distributed and the pain caused is lighter. It is the most commonly used injection method. The injection site is usually the plump buttocks or neck. When injecting, cut the hair and disinfect it. Hold the syringe in your right hand and stab the needle vertically. The depth can vary according to the size of the pig, usually around 3cm.

Subcutaneous injection

The liquid medicine is injected into the loose tissue between the skin and the muscle. The injection site is generally chosen in the inner thigh and behind the ear root. During injection, disinfect the injection site first, lift the skin with the thumb, index finger and middle finger of the left hand to form a triangular fold, and stab the syringe needle in the center of the fold with the right hand at an oblique Angle to the skin at a 45° Angle. Release the left hand to push the syringe and inject the liquid medicine.

intravenous

It is a kind of treatment technology in which the medicine liquid is injected directly into the blood vessel and the effect of the medicine liquid occurs quickly. It is mainly used to rescue critically ill pigs, generally selected in the dorsum of the ear and the great auricular vein. First rub the big vein with alcohol cotton ball at the back of the ear, so that the vein anger Zhang; The assistant pressed the vein at the base of the ear with his fingers to make the blood vessel bulge. The injection personnel held the pig's ear with his left hand and stabbed the needle into the blood vessel with his right hand at an Angle of 10 degrees to 15 degrees. To relax the pressure at the root of the ear, the injector fixed the needle with the left hand, pushed the piston with the right thumb to slowly inject the liquid medicine, and then pressed the needle hole with the alcohol cotton ball to quickly pull out the needle, so as to avoid hematoma.

Intraperitoneal injection of

The liquid medicine is injected into the abdominal cavity. Pigs often use this method. The injection site was 3 to 5 cm below the anterior edge of the pubic bone in large pigs and lateral to the midline. Injection method: large pigs are usually placed on the side, and the abdominal skin is pinched with the left hand. The needle is inserted perpendicular to the abdominal wall and punctured through the retroperitoneum to be injected. The pig can be raised by the breeder with two hind limbs upside down, with two legs gently clip the pig's forebody to keep the pig fixed, so that the intestinal tube moves down, injection personnel face the pig's abdomen, under the pubic front and the direction perpendicular to the abdominal wall, punctured through the peritoneum can be injected. Injection should not be too deep or partial to the front, so as not to damage the internal organs, nor too much partial to the rear, so as not to damage the bladder filled with dropsy urine.
