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.
将怀孕和未怀孕的雌性兔子置于炎热（33摄氏度）和寒冷（3摄氏度）的环境中，并测量它们的核心体温。与未怀孕的兔子相比，即将分娩前3天的怀孕兔子在热应激环境中维持正常体温的能力较弱。这种体温调节能力的改变可能会使一种对未怀孕兔子无害的环境温度变化，对母兔和幼崽都有潜在危害或致命危险。
