Abstract: The pulsatile secretion of LH was monitored in Shiba goats during the gestation (3 animals) and the postpartum suckling period (4 animals), by measuring plasma LH levels at 10-min intervals for 4 hr on three occasions in each reproductive phase: early-, mid-and late-stages, respectively. Except for one case at the mid-gestation stage, the LH secretion remained inactive throughout the gestation period showing none or one LH pulse/4 hr with low amplitude. The pulsatile secretion of LH with an amplitude of greater than 1 ng/ml resumed within a few weeks after kidding in 3 out of 4 animals, followed by the resumption of estrus at variable postpartum intervals (15 to 66 days), whereas the pulsatile LH secretion did not resume in the other animal which remained acyclic at least until day 78 postpartum. These results demonstrate that the pulsatile secretion of LH decreases throughout the gestation period and the increase of the LH pulse frequency after kidding would be a prerequisite for the resumption of the postpartum ovarian cycle in suckling Shiba goats. |
