ABSTRACT
In order to evaluate the use of different sources of iron to prevent iron deficiency anemia and to appraise the performance of suckling piglets, we sorted 202 piglets in five treatments. ID - intramuscular injection of 200mg of iron dextran on the third day of age; T24 - free daily access to land provided to piglets every 24 hours from the third to the nineteenth day; T48 - free daily access to land provided to piglets every 24 hours from the third to the tenth day and from day 11 to day 19 with an interval of 48 hours; T72 - free daily access to land provided to piglets every 24 hours from the third to the tenth day and from day 11 to day 19 with an interval of 72 hours; FS - Food supplement rich in iron-chelating powder (SAUP) available from the third to the eleventh day with an interval of 48 hours. The iron dextran applied on the third day of life as well as the supplementation with land and SAUP were effective to ensure the performance of piglets during the lactation period and did not affect feed intake or the viability rate. The different sources of iron studied did not influence the WBC (White Blood Cell) and succeded in preventing iron deficiency anemia and performance of suckling piglets. Regarding the concentrations of hemoglobin and hematocrit, the animals supplemented with iron dextran showed higher values when compared to those who receive land and SAUP.
