One-year-old blood test and test, is a routine work of the scale pig farm. The intravail venous blood is a commonly used blood collection method. However, it is not a lot of veterinarians who can use the intravenous venous blood of the prostate. Due to the lack of detailed introduction to this technique, many grassroots veterinarians often think that intravenous blood is a complex technology, requiring superior operation skills. In fact, as long as you master the operational essentials, through a short time speaking, each veterinarian can master this technology. Generally, the people who have learned an animal husbandry and veterinary explanation and demonstration through an hour of explanation and demonstrations.

Application of prostate vena cava blood collection method is more than half of the time than traditional ear veins, and the blood sample is cleaned. General veterinarians blood in this method, each blood collection 30 pigs 40 commodity pigs, can complete the task for less than 3 hours.

Points of intravenous blood collection technology
1. Select the appropriate syringe and needle.
The syringe is typically a disposable syringe of 5 ml of specifications. Due to different sizes of pigs, the depth of the vena cava is different, and the needle that requires the use is not the same. The needle is too short, causing the front cavity; the needle is too long, it may pierce the front vein. According to the experience of my operation, there is a 16 # 50mm needle (this needle pig farm is not commonly used, but many needle manufacturers can be produced, can be found in the local veterinary pharmaceutical sales store); 30kg or more Pig, should choose 12 # 38mm needle; 10-30kg pig, optional 9 # 25mm (medical disposable syringe constitutive needle); 10kg less lactaria, should choose 9 # 20mm needle (otherwise included A specification of the needle).

2. The Baoding of the pig.

Public sows are guaranteed by Baoding Rope, requiring high as much as possible, so that the head and necks of pigs are 30 degrees above 30 degrees, so that they are both convenient for blood collection personnel to see the blood collection site, but also make the foreclock venae Outward, venous blood can be bloated. Middle and big pigs above 20kg, from 1-2 breeders to take a pig (or Baoding rope), head is standing, biased toward the right; the pigs below 20kg can be grasped by 1-2 breeders. Insert, react relying on the column.

3. Find the neutral part.

The front cavity of the pig is, the more shallow the head, but the worse, the more the chest is clung, but the deeper. Therefore, blood collection should be selected. If the part of the small pig is too small, the blood vessel is too small, it is difficult to tie, and it is difficult to extract blood, so the blood collection site of the pig should be slightly later. The blood vessels and male pigs in China are relatively large, they are too deep, and the needle is not enough, so it should be brought to before. According to my experience, the pigs below 20kg should be used to pick up the intersection of the two proimers and trachea, and the big pigs in the mamato and more than 20KG can choose the closest portion of the neck.

4. Neck and blood.

Pigs: Align the parts described above, and use the needle vertically. Tensioning the syringe piston, if the needle is in the front cavity venous, it can be seen from the blood vessel source from the blood vessel source to extract the required blood volume. If the blood is pumped, the needle is not tied, and the needle can be up and down until the blood flow is seen in the syringe.
Magong sow and medium pigs: the counterparts are adjusted, so that the needle is biased toward the air pipe in the direction of the needle, tightening the syringe piston, and the blood flows out. If there is no blood flow, it means that there is no tie, it may be deeper with a deeper in the forekin, and the hand can be used to distinguish the needle. If you still can’t get blood, you can slightly retire the needle, or sway the needle left until there is blood flow out. In fact, after the operation is skilled, there is no tie in the needle. You can feel it by hand, when the needle is tie, it can feel a slight “Bu”.

Precautions for intravenous vena cava

The pig’s prostate vena cava blood collection, although the difficulty is relatively large, but if the technical skills, the blood collection is smooth, saved, the blood is also more, so most A common method of blood collection. In order to master the intravenous venous blood collection technology, the author believes that there are some precautions:

(1) Use the appropriate syringe and needle. Due to different sizes of pigs, the depth of the front cavity is different, and the needles that require the use are different. If the needle is too short, the thorn is not in the foreclock; the needle is too long, it may pierce the entire foreclock, which is not blood. The needle type used in accordance with the size of the pig is as described above. The syringe for blood collection is preferably used, otherwise it must be kept drying.

(2) Be a good job in the security of people. According to the size of the pig, different setup methods are used. After the Baoding, the pigs should be relatively stable, and they cannot be turned to sway or rear. The chest nest must fully expose to smooth blood intravenous blood. When you grab the pig, when Baoding pig, the action should not be rude, try to use touch action to make it quiet. Especially in the nasal roller sleeve or metal ring ring, it is necessary to avoid people being bitten or injured in the pig.
(3) Selection of the adjusted portion. The porcine front cavity is worse than the head, but the worse, the more the chest is clung, but the deeper, so the blood collection should be selected. Master a certain direction, angle, and depth when entering the needle, and adjust it in time. The blood vessel is pierced and will cause hematoma. To stop blood collection immediately, you must change the blood of another pig. It is important to pay attention to the blood of piglets, can’t be too fierce, too deep, to avoid injury and cardiac or heart.
(4) Handling the blood used. After the blood, the blood in the syringe should be immediately injected along the container (test tube) of the storage of blood, and it cannot be blisted, and it cannot be oscillated, and the tilt is placed. It is also possible to place a check after tilt in the syringe. To be checked, the summer is placed at room temperature for a while, and the winter is placed in the warm water in warm water in 25 ~ 37 ° C for a while, and the blood is analyzed. If anticoagulant whole blood is needed, an anticoagulant is required in the syringe or tube. Note that when penicillin is stored in blood or serum, penicillin is cleaned by disinfecting water, and then dried with water. When the blood sample is detected, the amount of ice cubes plus blood in the incubator will prevent blood deterioration and try to prevent dramatic oscillation during the test.

Current pork disease is becoming more complicated, many diseases are only difficult to diagnose only with traditional eye lesions or inherent experience. The traditional prevention and control model does not adapt to the prevention and treatment of pig disease in the new era, to carry out correct diagnosis and analysis of pig disease, implement daily hypervisor monitoring and immune antibody monitoring, and provide technical support for the prevention, control and purification of the disease, must be carried out Serological testing. The intravenous venous blood collection method must be skilled in the first-line veterinary personnel. I believe this technique will be able to carry forward the larger pig farm.
