Which deficiency is primarily associated with anemia in livestock?

• A. Iron deficiency
• B. Iodine deficiency
• C. Vitamin D deficiency
• D. Vitamin A deficiency

Answer: (A)

Iron is required to make hemoglobin, the component of red blood cells that carries oxygen. When animals don’t get enough iron, hemoglobin production falls, leading to fewer healthy red blood cells and anemia. In livestock, this is especially common in young animals like calves and piglets, because they grow rapidly and milk supplies little iron unless it’s supplemented. The result is pale mucous membranes, lethargy, and slower growth due to reduced oxygen delivery to tissues. Iodine deficiency affects thyroid function and can cause goiter and metabolic problems, not a direct drop in hemoglobin. Vitamin D deficiency leads to bone problems such as rickets and osteomalacia, not anemia. Vitamin A deficiency causes issues like vision problems and impaired immunity, and while it harms overall health, it isn’t the primary cause of anemia.
