Infant male rats whose dams received dietary conditions of zinc deficiency or undernutrition during their last trimester of pregnancy showed, as compared to rats from normal-diet mothers, no differences in learning a spatial discrimination, deficits in relearning following a retention interval of 14 days, and no differences in relearning and no evidence of retention (when compared to maturational controls) following a retention interval of 70 days.
