Concept:Piglet anaemia occurs mainly because of iron deficiency in newborns.
Explanation:Young piglets receive very little iron from sows’ milk.
So their body iron stores become low soon after birth.
This deficiency causes a reduced production of haemoglobin, leading to anaemia.
Anaemia in piglets is therefore prevented and controlled by supplying iron supplements.
These supplements are commonly given in the form of iron drugs or injections.
They help restore normal red blood cell formation and prevent weakness or death.
Sulphur drugs, anthelmintics, and antibiotics do not correct this deficiency.
Anthelmintics remove worms, while antibiotics fight bacteria, and sulphur drugs act on infections.
Hence, the most appropriate control method is the administration of iron drugs.
Answer:B. iron drugs
