[Effect of cross-fostering on various physiological and behavioral features in Wistar and genetically cataleptic rats].
In the GC rats reared by their natural mothers the plasma corticosterone concentration and open field locomotion were lower than in Wistar rats whereas the startle-reflex amplitude was higher. Cross-fostering did not affect the plasma corticosterone concentration or the startle-reflex amplitude. A negative correlation between these parameters was found. An open field test yielded lower results in Wistar rats reared by foster mothers belonging to the GC strain whereas the reverse cross-fostering did not affect the locomotion in GC rats. The data suggest that fostering affects the open field behaviour whereas cross-fostering effects depend on the genotype of fostered litter.
