| Popis: | Pregnancy wastage resulting from abortion and stillbirth are a confounding problem for practitioners given the low rate of confirmatory diagnosis. The role of nutrition has been implicated in fetal development and postnatal survival yet minimal evidence has been provided to support a diagnostic connection. This clinical review will provide the background to understanding trace mineral and fat-soluble vitamin metabolism during gestation, implications on abortion, stillbirth, and neonatal survival, and opportunities for diagnosis and prevention. Histologic lesions in aborted or stillborn calves consistent with either iodine or selenium deficiency support a direct role of these trace minerals. Comparison of hepatic mineral concentrations in aborted, stillborn, and abattoir calves suggests other trace mineral and vitamin A deficiencies in these losses, but a more definitive cause and effect association is needed. Maternal nutrition during gestation is critical to ensuring adequate trace mineral and vitamin status during fetal development and into early postnatal life. |
