title: Behavior of male rats fed low levels of metallic salts.
abstract: Male rats at 44 days of age were fed diets ad lib containing the following in ppm by weight: Co++(75), Cu++(75), Fe+++(150), Mn++(75), Ni++(75), Pb++(10) and Zn++(75), the controls receiving the basal ration. At days 55-56 of feeding, the rats were subjected to the poke test and no remarkable differences could be discerned in the 5-minute ratings; for the first one-minute scores, a small but significant change was apparent with Fe+++ vs Pb++. Performance of the animals in a runway was ascertained at days 73-74 of feeding and discounting the poor performers, namely, those which did not run the maze in 100 seconds, only few definite differences were noted (Zn++ vs Pb++ and Mn++ vs Pb++).
