Changes in the levels of progesterone, oestrogen, PGE1 and PGF2 alpha in Xinong Saanen dairy goats during parturition



Changes in the levels of progesterone, oestrogen, PGE1 and PGF2 alpha in Xinong Saanen dairy goats during parturition



Acta Veterinaria et Zootechnica Sinica 16(4): 217-223



Radioimmunoassay of serum from 10 goats showed a rapid fall in progesterone content and a gradual rise in oestrogen from 72 to 12 hours before parturition. The PGF2 alpha showed a gradual rise from 60 hours before parturition. When the cervix opened, the oestrogen, PGE1 and PGF2 alpha rose rapidly, and at parturition reached peak values of 2158 +or- 294, 1397 +or- 398 and 744 +or- 181 pg/ml, respectively.
