At the 14th to 16th week of pregnancy the copper content in the maternal liver was low while that in the fetus was high. After ovariectomy there was a decrease in liver copper and ceruloplasmin which was prevented by treatment with oestrogens but not with progesterone. Five groups of sheep were studied: control (barren ewes), pregnant, ovariectomised and ovariectomised treated with oestrogens or progesterone. In all, with high or low liver copper, the nuclear fraction contained the most copper. This suggests a species specificity of the copper metabolism in sheep.
在怀孕第14至16周时，母体肝脏中的铜含量较低，而胎儿体内的铜含量较高。卵巢切除术后，肝脏铜和铜蓝蛋白含量下降，雌激素治疗可预防这种下降，但孕激素则不能。研究了五组绵羊：对照组（未孕母羊）、怀孕组、卵巢切除组以及用雌激素或孕激素治疗的卵巢切除组。总体而言，无论肝脏铜含量高低，细胞核部分含铜量最高。这表明绵羊铜代谢具有物种特异性。
