Although maternal aggression in rats is confined to a restricted post-partum period, the high and stable aggression level and the constancy of its behavioural structure make it an attractive experimental procedure for studying the behavioural effects of psychotropic drugs. Female rats were tested against naive male intruder rats for 5 or 10 min on post-partum days 3-9, during which aggression is stable. Chlordiazepoxide (CDP; 5, 10 and 20 mg/kg, orally) had a biphasic effect on aggression; it increased aggression considerably at 5 and (to a lesser extent) at 10 mg/kg. At 20 mg/kg aggression returned to control level. CDP shortened the latency to the first attack at 5 mg/kg, but not at higher dosages. CDP enhanced aggression, particularly in the first 2 min of an encounter. It did not change the structure of the aggressive behaviour, but did induce a dose-dependent increase in feeding. Fluprazine (Flu; 5, 10 and 20 mg/kg IP), a specific antiaggressive (serenic) drug, induced a dose-dependent decrease in aggression and exerted its largest effect in the first 2 min of an encounter. In accordance with the reduced aggression, latencies to the first attack increased. Maternal aggression in rats represents an extension to other (male) aggression paradigms in psychopharmacology. First, it has no male counterpart. Secondly, the hormonal mechanisms underlying this behaviour differ from those of male aggression. Thirdly, the morphology of maternal aggression is different from that shown in male models of agonistic behaviour (e.g. resident-intruder). These features make maternal aggression an attractive paradigm for pharmacological studies of female behaviour.
