At a dietary level of 5%, Be sulfate and Be carbonate completely inhibited growth of rats and caused some mortality. A rickets-like condition occurred in these rats. Food intake was reduced by about 50% but this did not account for all growth inhibition as shown by a paired feeding experiment. Return to stock diet after a prolonged period of ingestion of Be salt allowed rapid but not complete growth recovery. Be sulfate was more toxic to old rats than to weanlings, but with Be carbonate mature rats seemed to be more resistant than weanlings. Be carbonate at a level of 2.3% of the diet caused some weight depression in rats. Be metal at a 10% dietary level and Be oxide at a 5% dietary level did not affect the growth of rats. 11 figs., 2 tabs.
