Fig. 1. Growth of mice fed synthetic zinc adequate and zinc deficient diets. In two experiments mice weighing 16.0 ± 0.7g were divided into two groups receiving either a zinc adequate (30 mg Zn/kg) or zinc deficient ( 0.6 mg Zn/kg) diet in a 50 d dietary regime in which mice receiving zinc deficient diet developed ChrZD. Values are expressed as mean ± SD plotted at each growth point for each experiment. For each experiment ZA n = 9 ChrZD n = 8. *significantly different from ZA mice, p < 0.05.
