	abstract = {As part of a study measuring the effect of a variant of insulin-like  growth factor-1 (long-arg3-IGF-1; LR3IGF) on tissue amino acid utilisation  in sheep, changes in plasma Cu, Fe and Zn concentrations were observed.   LR3IGF-1 was infused continuously over 21 days into the skin of 6 sheep  using a bilateral arterio-venous preparation. Another 6 sheep were infused in  the same way with saline only (controls). Feed intakes were the same for  both groups. Arterial blood samples were obtained prior to the start of  treatment and at 1, 7, 14 and 21 days. Plasma samples were prepared and  analysed for concentrations of endogenous IGF-1, insulin, cerulophasmin,  macro-elements (Ca, Mg, Na, P and S) and the trace elements, Cu, Fe, Mn  and Zn. Plasma concentrations of the macro-elements were unchanged over  the treatment period and were not significantly different between the two  groups. However there was a significant effect of treatment (P<0.001) and  treatment x time interaction (P=0.024) on the Cu concentration in plasma.   After 7 days the Cu concentration in plasma of the LR3IGF-1 group  increased from 1.06},
