Tissue samples were taken from 130-day-old fetuses from ewes fed a synthetic diet low in copper (Cu), a Cu-supplemented synthetic diet, or a roughage diet adequate in Cu content. The fetal liver and kidney Cu concentrations were substantially lower when the dams were fed the Cu-deficient ration than when they were fed the Cu-supplemented ration or natural diet. Differences between dams' rations in Cu concentrations for the other 3 fetal tissues (spleen, heart, and lung) were small. Differences among groups in fetal tissue iron concentrations were not significant at the P greater than 0.05 level. Concerning zinc concentrations, there were significant interactions between dams' diets and fetal tissues, mainly attributable to differences between rations in liver, heart, and kidney zinc levels. For manganese, the difference among dams' rations and among fetal tissues were significant at the 1% level, but the interactions of ration x tissue were also significant. Heart and spleen manganese concentrations were substantially higher in the fetuses from dams given Cu-deficient diet than in fetuses from dams fed Cu-adequate diet.
从130日龄胎儿获取组织样本，这些胎儿来自喂食低铜（Cu）合成饲料的母羊、补充铜的合成饲料的母羊或铜含量充足的粗饲料饮食的母羊。当母羊喂食缺铜日粮时，胎儿肝脏和肾脏的铜浓度显著低于喂食补充铜日粮或天然日粮时。其他3种胎儿组织（脾脏、心脏和肺）的铜浓度在母羊日粮之间的差异很小。胎儿组织铁浓度在P大于0.05水平时，各组之间差异不显著。关于锌浓度，母羊日粮与胎儿组织之间存在显著相互作用，主要归因于肝脏、心脏和肾脏锌水平在日粮之间的差异。对于锰，母羊日粮之间和胎儿组织之间的差异在1%水平上显著，但日粮×组织的相互作用也显著。喂食缺铜日粮的母羊所生胎儿的心脏和脾脏锰浓度显著高于喂食铜充足日粮的母羊所生胎儿。
