Imparied thermoregulation in pregnant rabbits at term.
Pregnant and nonpregnant female rabbits were placed in hot (33 degrees C) and cold (3 degrees C) environments and their core temperatures measured. Pregnant rabbits during the 3 days before giving birth were less able to maintain normal body temperatures in thermally adverse environments than were nonpregnant rabbits. This alteration in thermoregulatory ability may permit an environmental temperature change that is not dangerous to nonpregnant rabbits to be potentially harmful or lethal to both mother and offspring.
