Peripheral blood samples were collected throughout pregnancy from 11 red deer hinds. During the same period, 6 other hinds which mated but failed to produce calves were also sampled. Pretreatment of some of these hinds included synchronization of oestrus alone (N = 3) or with injection of 1000 i.u. PMSG (N = 9). During early and mid-pregnancy, LH and prolactin were frequently undetectable. Prolactin concentrations in pregnant and non-pregnant hinds were high (greater than 250 ng/ml) in December-January. The results of the hormone analyses suggested that the amount of progesterone in plasma correlates with the number of corpora lutea (CL) present. The concentrations of oestradiol and progesterone were low from mid-winter onwards in the non-pregnant hinds, suggesting a reduction in ovarian activity at this time. In pregnant animals, progesterone concentrations were high for the first 200 days of gestation. Oestradiol rose to peak values concomitant with declining progesterone concentrations just before parturition.
在整个孕期从11头马鹿母鹿采集外周血样本。同期，对另外6头交配但未产仔的母鹿也进行了采样。其中一些母鹿的预处理包括单独的发情同步处理（N = 3）或注射1000国际单位孕马血清促性腺激素（PMSG，N = 9）。在妊娠早期和中期，促黄体生成素（LH）和催乳素常常检测不到。在12月至1月期间，怀孕和未怀孕母鹿的催乳素浓度都很高（大于250纳克/毫升）。激素分析结果表明，血浆中孕酮的量与黄体（CL）数量相关。在未怀孕的母鹿中，从冬中开始雌二醇和孕酮浓度较低，表明此时卵巢活动减少。在怀孕动物中，孕酮浓度在妊娠的前200天较高。就在分娩前，雌二醇随着孕酮浓度下降升至峰值。
