Body weight and tissue copper levels in male rat pups on postnatal days 19 and 23

	P19		P23
Characteristic	CuA	CuD	CuA	CuD
Body weight (g)	51.4 ± 2.1	49.9 ± 1.5	72.5 ± 3.5	67.6 ± 2.6
Brain copper (μg/g)	2.04 ± 0.03	0.57 ± 0.04*	2.33 ± 0.05	0.63 ± 0.04*
Liver copper (μg/g)	32.9 ± 3.6	1.25 ± 0.16*	18.4 ± 3.6	0.87 ± 0.07*

Values are mean ± SEM (n = 4 for P23, and n = 7–10 for P19). Cu-adequate (CuA) mean values were compared to Cu-deficient (CuD) male rat pups (*P < 0.05)
