Male albino rats (Charles River) were maintained on a basal soy-protein diet, unsupplemented with Zn and with 1.6% Ca for 4 weeks (Ca)(Phy)/(Zn) = 9.4(molar). Animals were subdivided in 2 expts. between soy-protein 0.8% Ca, 11.24 mg Zn/Kg diet (4.2(molar)) or 1.6% Ca, 11.21 mg Zn/Kg (9.4(molar)) and egg albumin 0.8% Ca, 0.46 mg Zn/Kg diet and 1.6% Ca, 0.37 mg Zn/Kg diet at which time each animal was injected with 10 ..mu..Ci /sup 65/Zn. Daily fecal collections were made for 14 days and ratios of /sup 65/Zn Soy:Egg alb. calculated. The very low concentration of Zn in the egg albumin diet restricted the pancreatic secretion of Zn and the differential effect of phytate on these diets was not apparent as shown earlier with soy and casein diets. This was also reflected in the growth rates of the exptl. groups in that the egg albumin fed rats gained -4.4 and -9.0 g/wk; soy fed rats gained 28.0 and 17.3 g/wk.
