Popis:	This experiment was conducted to investigate the effects of iron from an amino acid complex (Availa-Fe ® ) on the iron status of neonatal and suckling piglets. A total of 24 gestating sows (Landrace×Large White) were randomly allocated to three dietary treatments. The control diet contained 80 mg kg -1 Fe from ferrous sulfate heptahydrate (FeSO4⋅7H2O), while the two experimental diets were supplemented with an additional 120 mg kg -1 Fe from Availa-Fe ® or FeSO4⋅7H2O, respectively. The lactating sows remained the same iron treatments as gestating sows, while neonatal piglets of 24 litters born from the above sows were allotted to another three treatments. Piglets from the sows of the control treatment were fed basal diet with no supplemental Fe as control treatment, but were injected with 100 mg Fe as Fe dextran at birth. Piglets from the sows of Availa-Fe ® or FeSO4⋅7H2O treatments were supplemented with 120 mg kg -1 iron from Availa-Fe ® or FeSO4⋅7H2O, respectively. The total born alive and weaned, and the average piglets weight at birth and at weaning were not significantly affected by the sow's dietary treatments (p>0.05). Iron from Availa-Fe ® did not demonstrate a statistically significant improvement in hemoglobin concentration, hematocrit and plasma iron of sows on day 90 and 105 of pregnancy and the milk iron of sows during lactation (p>0.05). Neonatal piglets in the Availa-Fe ® treatment had a significantly higher hemoglobin concentration (p 0.05) than those in the other two treatments, respectively. The hemoglobin of suckling piglets in the Availa-Fe ® treatment was higher than that of piglets in FeSO4⋅7H2O treatment on day 28 (p 0.05). However, the hemoglobin and hematocrit of suckling piglets injected with Fe were higher than those of piglets in the other two treatments (p
