Relative UCP1 expression for mRNA from brown adipose tissue of lambs from ewes fed low (3.2 ppm), medium (10 ppm), or high (20 ppm) Cu during the last two trimesters of gestation. UCP1, uncoupling protein-1. Lambs were held at 6°C (cold) or 28°C (warm) temperatures for 48 h postnatally. Prenatal Cu effect p = 0.02; postnatal temperature effect (warm vs cold) p<0.001; prenatal Cu X postnatal temperature interaction p>0.25. Pooled standard error bars for each treatment are attached to the symbols.
