Abstract

The plasma concentrations of progesterone and oestradiol-17p during pregnancy and the first 20 days after parturition were estimated in reindeer. The concentration of progesterone in the period 75–25 days prior to parturition was significantly higher than in the period 200– 75 days prior to parturition (P < 0.001). During the last 25 days before parturition the concentration decreased significantly. The concentration of oestradiol-17β was in most cases below 70 pg/ml until 50 days prior to parturition. During the last 25 days of pregnancy there was a significant increase in oestradiol-17β and the ratio progesterone/ oestradiol-17β was markedly lower than in the period 75–25 days before calving.

摘要

对驯鹿孕期及分娩后前20天的孕酮和雌二醇-17β血浆浓度进行了测定。分娩前75 - 25天的孕酮浓度显著高于分娩前200 - 75天(P < 0.001)。在分娩前最后25天,浓度显著下降。在分娩前50天之前,大多数情况下雌二醇-17β浓度低于70 pg/ml。在孕期最后25天,雌二醇-17β显著增加,孕酮/雌二醇-17β比值明显低于产犊前75 - 25天。
