Response of serum zinc concentration to experimental conditions

Treatment	Duration of dose, h	Serum zinc concentration, μg/ml
Dietary zinc content, mg Zn/kg diet
5		0.5 ± 0.1^a
30		1.4 ± 0.2^b
180		2.0 ± 0.2^c
Oral zinc dose, mg Zn/kg body weight
0	2	1.4 ± 0.3^a
35		3.1 ± 1.4^b
0	6	1.4 ± 0.1^a
35		1.6 ± 0.2^b

Concentrations were determined by atomic absorption spectrophotometry and are expressed as the mean ± SD (n = 4–6). Within each experiment, a statistically significant difference (P < 0.05) is indicated by a different letter.
