The direction of temporary phase shifts depends on the timing of the light signal in the dark period (1800-0600). Delays predominated following signals between 2100 and 2400, while advances tended, even more uniformly, to follow signals given between 0100 and 0400. In one animal the caecotrophy rhythm split into 2 components after a light signal at 0400, while in another it was so disturbed that the signal was followed by a coprostasis of 10 days. The phase responses to light stimuli of the rabbit caecotrophy rhythm correspond well with those obtained in nocturnal rodents.
暂时相位偏移的方向取决于暗期（18:00至06:00）内光信号的时间。21:00至24:00之间的信号之后延迟占主导，而提前则更一致地倾向于跟随01:00至04:00之间给出的信号。在一只动物中，04:00的光信号后盲肠营养节律分裂为两个成分，而在另一只动物中，该节律受到严重干扰，信号后出现了10天的排粪停滞。兔子盲肠营养节律对光刺激的相位反应与夜间啮齿动物的反应非常吻合。
