Hold the upper and lower jaws of the piglet with your thumb and forefinger and force the piglet to open its mouth to expose the canine teeth. Then cut the right and left pairs of canine teeth with diagonal scissors to cut the teeth. Be careful not to hurt gums and tongue when cutting teeth. The cut teeth do not allow the piglets to swallow.2. The teeth of each piglet should be disinfected to prevent bacterial cross-infection. If the piglets are born with a weak constitution, they will not be able to cut their teeth for the time being to strengthen their ability to compete for nipples. 3. After the piglets are born, cut off 8 sharp needle teeth. This will reduce the damage to the sow’s nipple. When there is a battle, it will also reduce the damage.
