摘要
本研究对初生、７、１４、２１、２８、４２、５６、７０和８４日龄等９个阶段日龄组的３４只新西兰白兔的体长、体重及主要内脏器官的重量或长度分别进行了测定。结果显示：４２日龄之前，仔、幼兔身体各部分随着体重的增加呈现较迅速的增长，至４２日龄后生长发育速度减慢、根据非线性方程Ｙ＝ａＹ＾ｂ计算的异速生长系数ｂ值，主要内脏器官的早熟序列为：胸腺－肾－心脏－胃－肝－小肠－脾－结，直肠－盲肠。
New Zeaand Whites were studied.The body weight,body length and the weight and /or lenghd of the main internal organs of New Zealand Whites were determined at 1,7,14,21,28, 42, 56,70 and 84 days old.The results show that the internal organs develop fast and in-crease as the increase of the body weight beform 42 days old。The early-maturing order of theinternal organs is thymus-kidney-heart-lung-stomach-liver-small instestine-spleen-colon and rectum-cecum according to the allometry coefficient b calculated by the curvilinear e-quation Y =aXb.
