Injecting pigs in the process of raising pigs is actually a simple and cumbersome process, but in fact, in this simple work contains a lot of technical problems, only fully understand the technology of needle-free injection to pigs, in order to do a good job of disease prevention. Authoritative experts will share the tips and practical knowledge for injecting pigs at Leman China Swine Conference.

Preparation before injection

(1) According to the size of the pig, fat and thin, injection type, dosage, adjust the appropriate injection pressure, as well as cleaning and disinfection agents and necessary supplies.

(2) Check whether the needle-free syringe is damaged, whether the injection head is blocked, and whether the combination with the needle/drug delivery hose is tight.

(3) All immunizing equipment should be cleaned and disinfected at high temperature before use.

(4) Before extracting the liquid medicine, check whether the drug has expired, whether there is turbidity, precipitation, deterioration; When more than two kinds of liquid medicine are mixed for injection, attention should be paid to whether the ratio is contraindicated.

(5) After pumping the liquid medicine, the air and bubbles in the syringe should be discharged before injection, and the knob for controlling the injection amount should be adjusted.

(6) According to the size of the pig, whether pregnancy, different injection sites and methods, take different protection measures, and require protection to be safe, reliable and convenient.

(7) Strictly abide by aseptic operation.

No needle injection site

In theory, needle-free intradermal immunity can be performed in any part of the pig herd, as long as it can be accurately achieved within the skin, but due to the strong body hair of the pig, try to choose the injection in the body hair sparse and soft part to avoid plugging and injection failure. And when we take different drugs or vaccines, it's better to choose the right site.

1) Piglet injection site: Piglet immune site selected back of the ear neck position. One is not to change the operation habits, the second is the piglet behind the ears neck position of the body hair is small and soft. Third, the neck position is close to the lymph nodes, which is more conducive to the immune effect.

2) Sow injection site: the immune site of the sow first on both sides of the vulva (diarrhea vaccine choose Houhai point), one is that there is no body hair on both sides of the vulva, the second is that the sow limit column/delivery bed is placed, and the back-end immunity is more convenient and quick, the third is that both sides of the vulva/Houhai point is near the lymph nodes, which is more conducive to the immune effect, and the fourth is that people do not touch the pig body. Houhai point, that is, below the tail root of the pig, this position will generally receive some diarrhea vaccines, such as stomach flow wheel, that is, viral diarrhea triple vaccine or double vaccine, transmissible gastroenteritis and epidemic diarrhea will hit Houhai point. The method of needle free injection in the Houhai point of pigs involves injecting vertically into the middle of a small nest located beneath the tail root of the sow

3) Nursery pig injection site: The immune site of nursery pig and piglet is the same neck position behind the ear. Without changing the operation habits, the efficiency of needle-free injection on the nursery pig herd is also higher. The pig can be stopped in a corner of the pig plate, because the pigs are crowded together, can not move, you can be injected head by head. It is best to color mark one end immediately after injection to avoid repeated injection.
