Changes in the levels of progesterone, corticosteroids, estrone, estradiol-17 beta, luteinizing hormone, and prolactin in the peripheral plasma of the ewe during late pregnancy and at parturition



Changes in the levels of progesterone, corticosteroids, estrone, estradiol-17 beta, luteinizing hormone, and prolactin in the peripheral plasma of the ewe during late pregnancy and at parturition



Biology of Reproduction 9(1): 30-35



Serial measurements (up to four times per day) of maternal plasma progesterone, corticosteroids, oestrone, oestradiol-17 beta , LH, and prolactin were made in six sheep, during late pregnancy and at parturition (d 0). The mean progesterone concentration on day-10 was 15.5 ng/ml. From day-4 the level began to decrease, and by day 0 the mean progesterone level was 1.0 ng/ml.
