The present study was conducted to investigate the cause of the structural changes of small intestine during lactation in albino rats. Anatomical measurements (total length, total wet weight and total dry weight) and histological studies of small intestine were undertaken in virgin control rats, lactating control rats, lactating rats with restricted food intake and lactating rats with restricted litter size. Restriction of food intake prevented the growth of small intestine during lactation, while restriction of litter size had no effect. Results indicate that the structural changes in small intestine are due to work hypertrophy secondary to hyperphagia and not due to any hormonal factors.
本研究旨在探讨白化大鼠哺乳期小肠结构变化的原因。对未孕对照大鼠、哺乳对照大鼠、食物摄入量受限的哺乳大鼠和窝仔数受限的哺乳大鼠进行了小肠的解剖学测量（总长度、总湿重和总干重）及组织学研究。食物摄入量受限会阻碍哺乳期小肠的生长，而窝仔数受限则没有影响。结果表明，小肠的结构变化是由于摄食过多继发的工作性肥大，而非任何激素因素所致。
