(1) injection of pigs: the neck side behind the ears. Near the hip (cross bone) near the hip. The injection point should not be moved back and downward to prevent puncture of the sciatic nerve. Once the sciatic nerve is injured, the ipsilateral hind leg is immediately mopped and cannot be loaded and maimed. (2) for pig subcutaneous fat thick (fat), and fat layer in the little blood vessels, such as liquid injection in it, it is difficult to be absorbed, not only can not play a role in treatment, and delay the disease. Pretend intramuscular injection must be based on the size of the pig. The length of the needle size. The principle is the length of the needle should be larger than the thickness and the thickness of the layer of fat pig, at least 1cm long, in order to ensure the liquid injection in the muscle cells. (3) do a good job in Baoding, do not hit "flying needle"". Pigs within 15kg can be held by both hands, holding two forelimbs, lifting Baoding. More than 15kg pigs, a corner of the door to the pigsty pigsty, make pigs each other together, unable to move, so that each injection head between the two ears on the top of the brain area as the color mark, so as to avoid re injection and leakage injection. The utility model has the advantages of simple and convenient operation, convenient injection, labor saving, and no disadvantage for the pig, and the needle is not easy to bend. [subcutaneous injection] (1) inject the liquid into the connective tissue of the skin, through the blood capillary. Lymphatic absorption into the blood circulation, sent to various organs. Therefore, absorption is slow, generally required by 5~10 minutes showing efficacy. Therefore, the injection of too many drugs should be injected at intervals. (2) the pig chooses the inside of the thigh inside the skin thin and subcutaneous more loose place, with more slender 5, 7, 9 needles inject. (3) when the first injection with his left hand to pinch the skin, make a wrinkle and lattice, right hand holding a needle into the needle from the Tao base, and the needle gently moves, such as the sense of light, that needle in the subcutaneous, medicine injection, after injection, the needle dial out, with a cotton ball on the pinhole.

A small amount of liquid medicine can be directly injected and injected by the injector, but the speed should be slow to prevent too fast. A plurality of liquid medicines are filled into the 50ml glucose bottle and connected by a transfusion tube and a needle head; the speed of infusion can be adjusted by the height of the infusion bottle, and the drip tube can be arranged in the middle of the infusion tube. (2) pigs were injected with ear vein. The point of the intravenous injection of pigs is not the intravenous injection itself, but whether the pig's Baoding is exact. Security. (3) 35kg within the pig, the lying in Baoding. With the first pig human side on the flat ground, a man grabbed two hind lower back strain, the other one with lateral neck hands or knees pressed crisp pig; large pig is first put into "cage", such as the cage is too wide, The available long board is inserted from the rear gap cage, the cage from the front side through the gap, can be pressed in "pig cage"; as long as the cage body, mobile anti swine before and after another, available from the side board insertion, removable pig disease prevention and. At the time of injection, pigs were caught from the space between the top of the cage and injected by the normal vein. This method is suitable for all kinds of male and female sows, especially for pregnant sows. If the pig body length ratio "s long, may be in the" cage "rear extension length, upper and lower, left and right with the two movable buckle and" cage "reverse connection. (4) intravenous injection before, wash the pig ear, even after disinfection, assistant pinch with your fingers the veins, or with a rope around the circle with a slipknot bolt tight, the ear vein filling, engorgement. If rainy day, pig light is not very good, can be used against the pig ear ventral side of the flashlight, the lights, from the ear vein side view is very clear. With its inhabitants left the pig's ear, and the ear tip topping up, right hand needle, the needle tip and the skin was 30o - 45o angle to penetrate the skin and blood vessel, gently withdrawing syringe see blood reflux, with the fingers of the left hand up and down together with the pig ear pinch in intravascular behind the needle tip so, can prevent swine commotion when induced by needle swinging, piercing the wall of the vessel. Before the injection, loosen the pressure ear finger or rope untied the slipknot, after injection, pull out the needle, needle hole by compression disinfection tampons, stay until the bleeding. [intraperitoneal injection] used mostly for piglets. Because the abdominal cavity can hold large amounts of liquid medicine and have more absorptive capacity, it can be infused with a large amount of liquid medicine at a time. But it must be a non irritating liquid medicine. When the weather is cold and the amount of liquid is injected more frequently, the medicine should be heated to 38 ~39. If the large pig, due to illness caused by ear cyanosis, unable to see the blood vessels, but also can be used for intraperitoneal injection. Piglets can lift two hind legs of Baoding, larger pigs can make their supine, high back, low posture. Before the injection, shake the hind legs of the pig and move the bowel forward. Then sheared. Injection site at the bottom of second, nipple about 1.5cm. Needle is best to use slender needle, before the injection of the skin to the side of a little bit away, and then perpendicular to the skin into the needle, so that the skin on the pinhole and abdominal muscles. The pinhole on the peritoneum is not in a straight line, which can prevent the infection of the abdominal cavity. When the needle is pierced into the abdominal cavity, the needle is pumped back to see if there is any intestinal content. If not, the liquid can be injected. The speed should not be too fast. After the injection, the needle is removed and sterilized. [] intrapleural injection for treatment of asthma, porcine pleuropneumonia, and some drugs directly into the chest cavity, and local treatment; in addition, also for swine enzootic pneumonia vaccine injection; can also be used to take for the laboratory diagnosis for pleural effusion. The injection site in the right chest wall, the penultimate intersection 6~7 intercostal and ischial tuberosity forward horizontal line (i.e., "Su Qi points"). Vertical needles are inserted perpendicular to the chest wall along the leading edge of the reciprocal sixth rib. Before the injection should be sheared, left the skin at the injection point move 0.5~1cm, then insert the needle back pumped into vacuum, slow infusion, local disinfection. [acupoint injection] this is a combination of traditional Chinese and Western medicine treatment, which contains acupuncture points of traditional Chinese medicine, regulating the physiological function of the animal body, and the role of Western medicine treatment. (1) to nest injection: for the treatment of various causes diarrhea, rectal and vaginal anesthesia and reduce pig nuze, injection of porcine transmissible gastroenteritis and diarrhea associated with two inactivated vaccine. The center of a depression between the ventral surface of the tail and the anus. The injection needle should be long needles, disinfected with alcohol before injection, the needle and the skin is smooth vertical piercing, prevent the tip up or down, up is thorn to tail vertebrae; down is pierced into the rectum, not only that the injection is invalid, but also damage the rectum. Disinfection after injection. (2) add edible acupuncture point: for the treatment of pig indigestion, appetite, anorexia. Feeding points in the pig ears behind the hairless area down the depression, about one point. Disinfect ahead, Needle vertical skin stab into about 3cm. The most commonly used liquid medicines are: 10% glucose solution, 10% camphor sulfonic acid sodium, neostigmine, compound vitamin B and other drugs. (3) Baihui injection: for the treatment of hind limb paralysis, lumbar and hip pain, urogenital tract infection, etc.. Baihui is located in the lower part of the lumbar cross depression, one point. Before the injection of local shearing, disinfection, needle piercing vertical 3~4cm infusion. Commonly used drugs are strychnine nitrate, neostigmine, An Naijin, gentamicin, kanamycin and so on. (4) Su Qi acupoint injection. Intrapleural injection.
