Measurements of body weight and body, tail and hindlimb lengths were made at various times during the postnatal development of the CFHB-Wistar rat using simple techniques which avoided unnecessary stress being applied to the animal. All the graphical relationships studied using these measurements indicated that growth was divided into two phases which meet at 16 days. This was particularly noticeable when either body length or hindlimb length was plotted against either age or body weight. Body weight appeared to be a better indication of maturity than time; and linear relationships were found when measurements of body lengths were plotted against the square root of body weight. Curvilinear graphs were obtained when body weight was plotted on alternative scales. Results suggest that prior to 16 days metabolism is probably directed more towards attaining sufficient maturity to enable the animal to survive independently, than to increasing its stature; but after 16 days this situation is reversed.
采用简单技术对CFHB-Wistar大鼠出生后发育的不同阶段进行体重、体长、尾长和后肢长度的测量，这些技术避免了对动物施加不必要的压力。使用这些测量值研究的所有图形关系均表明，生长分为两个阶段，这两个阶段在16天时相交。当将体长或后肢长度与年龄或体重绘制在一起时，这一点尤为明显。体重似乎比时间更能体现成熟度；当将体长测量值与体重的平方根绘制在一起时，发现了线性关系。当以其他尺度绘制体重时，得到的是曲线图形。结果表明，在16天之前，新陈代谢可能更多地是为了达到足够的成熟度以使动物能够独立生存，而不是增加其体型；但在16天之后，这种情况就会逆转。
