Twenty-four hour pattern of lutropin and progesterone pulsatile secretion base line in postpartum dairy cows.
Twenty-four hour patterns of lutropin and progesterone pulsatile secretion base line were studied in six postpartum dairy cows. The base line of lutropin showed three peaks within 24 hours. The base line of progesterone showed two peaks which coincided in the time with the nadirs of lutropin base line. These peaks show up clearly irrespective of the stage of puerperium.
