Seasonal and age related changes in size of reproductive structures of red deer hinds (Cervus elaphus)

摘要: Morphometric studies of uteri, ovary weights, and follicle diameters were carried out to investigate possible methodological applications. Size anatomical appearance the uterus varied with age phase in estrous cycle, both parous nulliparous females. The thus may provide valuable information on reproductive status for known-aged animals. Weight ovaries increased young, but declined old females, showing significant covariance body weight young prime ages. Ovary weights from low levels shortly after parturition a maximum towards end gestation period. Ovaries containing corpus luteum heavier than those without. Compared mean diameter largest ovarian an opposite pattern during yearly cycle. Maximum was non-ovulated size appear be limited value as criteria analysis performance.
