%A Dr. Mark B. Kristal %A Christina L. Williams %J Physiological Psychology %T The effects of strain, reproductive condition, and strain of placenta donor on placentophagia in nonpregnant mice %X The effects on placentophagia of strain, reproductive condition, and strain of placenta donor were observed in nonpregnant mice. Mice of the C57BL/6By and BALB/cBy strains were exposed to placentas of either strain after either no previous parturitional experience, one parturitional experience without nursing experience, or one parturitional experience with nursing experience. There was a significant effect of strain, a significant effect of reproductive condition, but no significant effect of strain of placenta donor. There was a significant interaction between strain and reproductive condition, but no significant interactions with placenta strain. It was inferred that the ability of a mouse to acquire and utilize relevant stimuli during and after parturition, in order to produce an emancipation of placentophagia from the physiological controls associated with parturition, is influenced by genotype. %N 4 %K placenta, placentophagia, mice, inbred strain, parturition %P 354-356 %V 1 %D 1973 %I The Psychonomic Society %L cogprints6218
