This experiment was conducted to investigate how the lactation regulation such as restricted-lactation, early weaning during the suckling period influences on ovarian functions in primiparous rats, on the bases of change in histological characteristics of ovary and mammary gland.
1. The ovaries of rats in middle lactation stage maintained the functional corpora lutea full of cytoplasm, and those of rats in late lactation stage contained matured ovarian follicles.
2. The milk was found full in the mammary gland tissue of NL rats, but short in the tissue of RL rats, and all the alveolar tissues were degraded in mammary gland of weaned rats. The alveoli structures of mammary gland of NL rats were uniformed on Day 10, but such uniformity was lost greatly on Day 20.
