Abstract

The relationship between male rat aggressiveness and the presence of a female was studied. Twenty 100-day-old dominant male albino rats were individually exposed to an inaccessible female rat in a specially constructed apparatus. The males were then given free-forced trials to an empty compartment or a compartment housing a submissive male. The results indicate that following exposure to an estrous female, dominant males increased their percentage of choices to the submissive male. Moreover, the incidences of aggressions by the dominant animal toward the submissive animal increased sharply after prior exposure to the estrous female. These data suggest that one antecedent source of aggression among male rodents may be the presence of a sexually receptive female.
