First, make Baoding, pay attention to safety. Second, choose the right syringe and needle. Third, select the position of the needle. The more the pig's anterior vena cava is, the shallower it is to the head, but the finer it is; the thicker the chest is, the deeper it is, so blood should be selected at the appropriate site. If the part of the piglet where the blood is drawn is too close to the head, the blood vessels are too thin and it is difficult to get in the middle. Even if it is struck, it is difficult to get bleeding. Therefore, the piglets should be drawn slightly behind. The pigs in medium and large pigs and sows have relatively thick blood vessels. They have deeper chests and can't reach blood vessels due to their needles. Therefore, they should be slightly forward. According to experience, pigs under 30 kilograms should adopt the intersection of two forelimbs and gas officials, and male and female sows, and 30 kilograms of medium and large pigs can choose the lowest cervical recess. Need to grasp the direction, angle and depth when entering the needle and adjust in time. The puncture of a blood vessel can cause a hematoma. If the blood is to be stopped immediately, blood should be exchanged for another pig. It is especially important to note that when the piglet draws blood, it should not be too fierce or too deep to avoid hurting the pericardium or heart.
