Changes in the hypothalamic-hypophyseal-ovarian axis of primiparous sows following weaning or pulsatile gonadotropin releasing homrone administration and weaning.
Lactating primiparous sows were used to examine relationships among hypothalamic gonadotropin releasing hormone (GnRH), serum, and anterior pituitary gonadotropins and follicular development after weaning or after administering GnRH pulses (1.5 ug) once hourly for 72 h before weaning. Control sows were either slaughtered at 0 or 72 h after weaning or were cannulated for collection of blood samp...

15 صفحه اولProgesterone therapy during early pregnancy and embryonal survival in primiparous weaned sows.
The experiment was conducted in primiparous sows to determine whether progesterone supplementation during early pregnancy could improve embryonal survival and to confirm a functional relationship between progesterone concentrations in the postovulatory period and embryonal survival. Thirty-four primiparous sows were fed for ad libitum intake from farrowing to d 21 of lactation, restricted to 50...
متن کاملOntogeny of metabolic effects on embryonic development in lactating and weaned primiparous sows.
Using an established experimental paradigm, feed restriction during the last week of lactation in primiparous sows reduces embryonic growth and development and produces female-specific embryonic mortality by Day 30 of gestation. Because this gender-specific loss of embryos at Day 30 was associated with changes in the variation of markers of epigenetic imprinting, the present study sought to est...
