Abstract

During pregnancy, metabolic adjustments occur in the mare to preserve iron stores in order to have adequate amounts for the growth and development of the equine fetus. The aim of this study was to analyze the evolution of hematocrit, iron, and ferritin in Spanish Purebred mares during pregnancy. A total of 31 Spanish broodmares aged 4–17 years old were studied during three similar periods of pregnancy (I, II, and III). Hematocrit (packed cell volume, PCV) was determined by microhematocrit and iron and ferritin concentrations were analyzed using spectrophotometry and turbidimetric methods, respectively. Pregnancy in the Spanish mare was characterized by a progressive increase in PCV and serum iron and ferritin concentrations. The physiological state of pregnancy significantly modifies iron status in these animals. In comparison with the first period, the increase in iron stores during the second and third periods indicates a positive iron balance, suggesting that the fetus can tolerate iron levels compatible with the mothers during the entire fetal development process.
