(2018-05-27)The 5-day Bee Synch + CIDR (Bee Synch) protocol for Bos indicus-influenced cows utilizes CIDR, GnRH (GnRH-1) and PGF on day 0 to eliminate mature corpora lutea, with FTAI and GnRH (GnRH-2) at 66 hours after CIDR removal ...

(Texas A&M University, 2005-02-17)Objectives were to determine if low-dose, continuous infusion of GnRH from Fall to Spring, would prevent seasonal anovulation in mares. Twenty Quarter Horse mares, ages 18 mo to 24 yrs, were stratified by age and body ...
-
(2017-12-10)Continuous infusion with native gonadotropin-releasing hormone (GnRH) restores follicular growth and ovulation in approximately 85% of winter anovulatory mares. However, the potential role of estradiol-17β (E2) in enhancing ...
-
(2014-12-12)The purpose of this experiment was to determine the effects of prenatal transportation stress (PNS) on LH, testosterone, and cortisol secretion before and after GnRH stimulation in sexually mature Brahman bulls. Forty-eight ...
-
(2013-01-28)The seasonal termination of ovarian cycles in mares initiated near the time of the autumnal equinox is a significant managerial issue for horse breeders world-wide. Studies presented herein had two over-arching aims. In ...
-
(Texas A&M University, 2006-08-16)We hypothesized that marked reductions in secretion of luteinizing hormone (LH) during transitional and anovulatory periods can be accounted for by similar reductions in hypothalamic gonadotropin-releasing hormone (GnRH) ...
-
(2012-07-16)Four experiments were conducted to test the hypothesis that RF-amide related peptide 3 (RFRP3) negatively regulate the secretion of LH in mares. In Exp. 1, mares received native gonadotropin-releasing hormone (GnRH) ...
-
(Texas A&M University, 2004-09-30)The physiological mechanisms through which nutrition mediates its effects in controlling reproduction are not well characterized. Both neural and endocrine components have been implicated in the communication of nutritional ...
-
(2016-01-11)Seasonal reproduction is highly correlated with circulating concentrations of luteinizing hormone (LH) in mares and low peripheral concentrations of LH serve as the primary basis for ovarian quiescence during the non-breeding ...
