The liver copper concentration of the bovine fetus and the hepatic and plasma copper concentrations of its dam during the first trimester of pregnancy were studied. The effect of the dam's dietary copper intake, age, sire breed and stage of pregnancy on her copper status and that of her fetus was also investigated. Simmental sired heifers had the lowest plasma copper concentration. The younger cows (two, three and four years) had significantly lower liver copper concentration than the older cows (six and seven years). The bovine fetal liver copper concentration was approximately 3.1 mmol/g DM and was not affected by dam's age, breed, stage of pregnancy, or copper status.
研究了妊娠前三个月牛胎儿的肝脏铜浓度及其母体的肝脏和血浆铜浓度。还调查了母体的日粮铜摄入量、年龄、父本品种和妊娠阶段对其自身及胎儿铜状态的影响。西门塔尔牛所生的小母牛血浆铜浓度最低。较年轻的母牛（2岁、3岁和4岁）肝脏铜浓度显著低于较年长的母牛（6岁和7岁）。牛胎儿肝脏铜浓度约为3.1 mmol/g干物质，不受母体年龄、品种、妊娠阶段或铜状态的影响。
