Abstract: The scent glandmorphological developments of musk rat(0ndatra zibethica)were determined in different seasons and divided into four stages of development :non—scent secreting stage, scent gland development stage peak level stage of scent—secreting and constant scent—secreting srage The scent was collected from i92 musk rats based on the morphorphogfcal sturctures and histological character tics of the muskrat scent gland at differe1t scelt-secreting Stages. Wich five times of counting scelt from one muskrat per year the total output of scent collected come to 2.65±0.32 g．Intramuscular injection of 5 mg／kg of testosterone propionate could induce the scent gland development and scent-secretingon muskrat during no-scent secreting period，and the level of scent secreting reach the same peak as that at the stage of scent—secreting.Feeding experiments proved that there was no effect of scent-collecting artificially on the reproductivity of the mating female muskrat.

摘要： 根据麝鼠香腺的形态发育，将其划分为非泌香期、香腺发育期、泌香盛胡和泌香持续期4个时期。通过对l92只成年雄性麝鼠分别进行5次活体取香，每只取香量累计达2.65±0.32 g。
非泌香期肌注丙酸睾丸索5 mg／kg，可诱导雄麝鼠香腺的发育和泌香。通过饲养繁殖观察，证明雄体取香对配偶雌体繁殖无不良影响。
