What is the best way for a pig to bite its tail?

In view of the prevention and treatment of the disease, we must first improve feed management and put in full-price feed. In addition, additives rich in minerals such as sodium, cobalt, calcium, copper and vitamin B should be added to the feed. Secondly, pigs whose tails have been bitten should be isolated and properly handled. If the injury is not serious, apply purple mercury after cleaning the wound to promote wound healing. If the wound bleeds, it should be pressed to stop bleeding. If there is local inflammation, erythromycin ointment can be applied. If it has caused systemic infection, you can control the infection by intramuscular injection of antibiotics such as penicillin. Pigs in other pigsty can be properly sedated to make them mentally stable. You can smear some bitter and nontoxic potions on pig tails (such as Chinese medicine made by Rhizoma Coptidis), so that when pigs bite each other's tails again, they will be bitter and forced to give up biting their tails.
