In a study designed to examine the role of the genotype on sensitivity to drug-induced behavioural changes, pregnant C57BL/6J and CBA mice were administered 60 mg/kg phenobarbital (PHB) intraperitoneally during days 10-16 of gestation. Following a balanced intrastrain fostering procedure, the behaviour of lactating dams was observed in their home cage at 2, 3, 5, 7 and 14 days postpartum. As the pups became older, maternal behaviour declined in control groups, whereas PHB dams of the CBA strain persisted in nursing their pups. C57 dams were generally affected in an opposite way by PHB exposure. For example, treated dams spent significantly less time in licking behaviour. Nest quality score was especially elevated in PHB dams of the CBA strain, while in C57 dams, nest-building was inhibited and nest quality unaffected by the previous PHB exposure. These results indicate that specific items of maternal behaviour can be differently affected by PHB exposure, and that the responses are affected by the genotype. To summarise, pups raised by treated dams may receive either exaggerated or insufficient maternal attention, as a result of changes in neurotransmitter systems and behavioural regulation following phenobarbital exposure. These results point to the need for a better understanding of mother/pup interactions in studies aimed at characterizing drug and toxicant effects on postnatal development.
