Intervals to estrus and ovulation in weaned sows depend partially on the diameter of ovarian follicles at weaning. The objective was to determine if follicular diameter in sows could be increased by a 48h period of GnRH infusion before weaning and wh

The weaning to estrus and weaning to ovulation intervals in sows are controlled by ovarian follicular growth after weaning. Longer intervals could be caused by smaller diameter follicles at weaning that take more time to reach a preovulatory size. We

Growth hormone plays a central role in the change in nutrient metabolism that occurs during the initiation of lactation. The actions of growth hormone are mediated by the growth hormone receptor (GHR) whose mRNA is present in three alternatively spli

An oestrous synchronisation protocol was developed for use in lactating dairy cows using PGF(2alpha), GnRH, and oestradiol cypionate (ECP). In experiment 1, lactating dairy cows received two injections of PGF(2alpha) (on days 0 and 11) (PP; n=10) or

Growth hormone (GH) is essential for postnatal somatic growth, maintenance of lean tissue at maturity in domestic animals and milk production in cows. This review focuses on neuroregulation of GH secretion in domestic animals. Two hormones principall

Timed artificial insemination (TAI) protocols use PGF(2alpha) and GnRH injections to synchronize ovulation. The objective was to evaluate the PGPG protocol (d 0, PGF(2alpha); d 3, GnRH; d 11, PGF(2alpha); d 13, GnRH and TAI) for first TAI and also ex

Uncoupling of the growth hormone (GH) axis in early postpartum dairy cows is correlated with a decrease in liver GH receptor (GHR) 1A mRNA and a decrease in liver GH receptor protein. Postpartum recoupling of the GH axis is also correlated with GHR 1

Growth hormone (GH) plays a role in metabolic adaptations that occur during lactogenesis. Liver GH receptor transcript (GHR 1A) is transiently decreased near parturition and may reduce GH-dependent signaling leading to low blood insulin-like growth f
