Description
Katlyn McClellan and co-authors tested, in a 2026 farm study, whether iron injections early in pregnancy improve sows' iron status and litters under commercial conditions. Two hundred thirty-five sows, from first-time mothers to veterans, were assigned at about day thirty of pregnancy to no iron, a moderate single dose, or a doubled dose split in two shots.
Blood hemoglobin and ferritin at late pregnancy rose in step with dose, while a binding capacity marker fell, the classic signature of better iron supply. A subset gave deeper blood panels, and all sows were followed through weaning for reproductive outcomes. The trial weighs a cheap intervention against the anemia that quietly taxes pig production. Dose, the data suggest, is a dial farms can actually turn.
