Piglet anaemia is a condition where newborn piglets lack enough iron in their bodies, leading to poor growth, weakness, and even death. The most effective way to control piglet anaemia is by using iron drugs. Iron injections or oral iron supplements can be given to the piglets soon after birth to prevent or treat anaemia. Sulphur drugs, anthelmintics, and antibiotics are not effective in controlling piglet anaemia. Sulphur drugs are used to treat bacterial infections, anthelmintics are used to control parasitic worms, and antibiotics are used to treat bacterial infections.
