Body growth using weight and length parameters have been examined following the introduction of the rice rat to laboratory conditions and a history of breeding covering some 15 generations. The pattern of growth shows a characteristic enphasic form which appears to be determined by the interplay of the external environment and the genetic endowment. The external environmental factors include the waxing and waning of the lactational performance of the mother and the intake of solid food, resulting in the first phase being mainly controlled by the maternal environment, the second phase being mainly controlled by a lessening maternal environment + external (solid food) environment + some genetics, the third phase being influenced by external environment + genetic endowment.
在将稻鼠引入实验室条件并经历了约15代的繁殖历史后，研究人员利用体重和体长参数对其身体生长情况进行了检查。生长模式呈现出一种典型的阶段性形态，这似乎是由外部环境和遗传禀赋的相互作用所决定的。外部环境因素包括母体泌乳能力的起伏以及固体食物的摄入量，这导致第一阶段主要受母体环境控制，第二阶段主要受逐渐减弱的母体环境+外部（固体食物）环境+部分遗传因素控制，第三阶段则受外部环境+遗传禀赋的影响。
