Copper, Manganese, Zinc, Iron and Calcium in Fetal Tissue of Baladi Goats at Northern of Jordan

Authors : Mutassim M. Abdelrahman

Abstract: Endemic deficiencies of minerals can be known by determining the concentration of these minerals in fetal tissues at different stages of gestation. Liver, kidney and bone samples were collected from fetuses of does (n=32), raised under extensive system, during routine slaughter operation at Irbid slaughterhouse at northern of Jordan. The fetuses` age were determined by crown to rump length measurements. Fetuses were grouped into three categories by periods: period 1, d 30 to 50, period 2, d 51 to 100 and period 3, d 101 to 150. All tissue samples were prepared and analyzed for Copper (Cu), Zinc (Zn), Manganese (Mn), Iron (Fe) and Calcium (Ca) by AAS. Selenium (Se) concentrations in fetal liver were also analyzed by AAS. Copper, Mn and Zn concentration in fetal liver and kidney were significantly lower (P<0.05) at late gestation compared with early and mid gestation, but liver Fe at late gestation was significantly higher (P<0.05) than at first two stages. Iron, Cu, Mn and Zn concentrations in fetal bone were significantly low (P<0.05) at late gestation. Selenium concentrations in fetal liver were significantly increased (P<0.05) with progress of gestation. Liver Fe concentrations were negatively correlated with kidney Fe (r= -0.60; P<0.01). Moreover, liver Cu concentrations were negatively correlated with liver Mn (r= -0.50; P<0.05). In conclusion, fetal liver Se and Fe storage was high and adequate during late gestation. On the other hand, Cu, Mn and Zn deficiencies and abnormalities of the newborn can be expected because of low fetal tissue reserve of these elements during late gestation.
