(1) Fetal rabbits of different gestational ages (20-29 days) were obtained by Caesarian section and term rabbits (31 days) by natural delivery. After dissection, organ weights were obtained and growth curves drawn. Brown adipose tissue was first visible at 22 days gestation and increased relatively more quickly than the body weight till day 26 after which it formed a constant percentage of the body weight. Growth of white adipose tissue followed a similar pattern, except that it was not visible until day 24. (2) The percentage triglyceride content of both types of adipose tissue increased throughout the latter part of gestation. (3) Fetuses of low birth weight had depressed fat stores in brown adipose tissue. (4) Some, but not all, of the high birth weight fetuses had relatively enlarged fat stores. (5) It is suggested that the conditions which produce fetuses of unusually low or high birth weight tend to have a greater corresponding effect on the fetal fat stores.
(1) 通过剖腹产获取不同胎龄（20 - 29天）的胎兔，通过自然分娩获取足月兔（31天）。解剖后，获取器官重量并绘制生长曲线。褐色脂肪组织在妊娠22天时首次可见，直至26天，其增长相对体重更快，此后在体重中所占比例保持恒定。白色脂肪组织的生长模式相似，只是直到24天才可见。(2) 在妊娠后期，两种类型脂肪组织的甘油三酯含量百分比均增加。(3) 低出生体重胎儿褐色脂肪组织中的脂肪储备减少。(4) 部分但并非所有高出生体重胎儿的脂肪储备相对增大。(5) 有人提出，产生极低或极高出生体重胎儿的条件往往对胎儿脂肪储备有更大的相应影响。
