The behavioral toxicity of cadmium (Cd, 100 ppm, through drinking water for 60 days) was assessed in growing male rats maintained on diets containing 21, 8 and 5% protein. Cd exposure in the 21% protein diet fed rats resulted in decreased body weight and growth, spontaneous locomotor activity and learning ability. The response latency in the learning situation was enhanced significantly. The decreases in the locomotor activity and learning ability were more marked in the 5% protein diet fed animals. The increase in the response latency was, however, more marked in the 8% protein diet fed group. Data indicate the enhanced vulnerability of protein malnourished animals to the behavioral deficits induced by Cd.
