P-64: Strategies to Optimize Reproductive Efficiencyby Regulation of Ovarian Function inyak (Poephagus Grunniens L.)
Background: To design a pre-Ovsynch hormonal strategy in yaks in order to increase the ovulatory response to the first GnRH injection of Ovsynch so that overall synchronization rate to Ovsynch could be improved. Materials and Methods: Non-lactating cyclic yak cows (n=33) were assigned to receive either no treatment before Ovsynch (control) or 0.375mg of PGF2(PreP) followed 2 d later by 10 g of ...
متن کاملEvaluation of the effect of a 3rd GnRH injection administered six days after the 2nd GnRH injection of Ovsynch on the reproductive performance of Japanese black cows
This study was designed to evaluate the reproductive performance of Japanese black cows following the 3rd injection of gonadotropin releasing hormone (GnRH) analogue administered concurrently with Ovsynch-based treatment on day 6 (day 1 = the day of ovulation). In Experiment 1, 12 cows were allocated into three groups: a control group that was subjected to Ovsynch treatment and then injected wi...
متن کاملP-164: Comparision The Effect of GNRH Agonist Administration versus Vaginal Progesterone on Serum Progesterone in Luteal Phase in Ovarian Hyperstimulation and Intrauterine Insemination Cycles in Unexplained Infertility
Background: To compare the effect of GnRH agonist administration with vaginal progesterone on serum progesterone in Luteal phase in control ovarian hyper stimulation and intrauterine insemination cycles Materials and Methods: In this clinical trial, 242 infertile patients because of UEI (unexplained inferetility candidate for ovarian stimulation and intrauterine insemination reffering to infert...
متن کاملDevelopment of a GnRH-PGF2α-progesterone-based synchronization protocol with eCG for inducing single and double ovulations in beef cattle.
Experiments were designed to investigate the effect of different doses and timing of an eCG treatment given during GnRH-based synchronization protocols on follicular dynamics and fertility in cattle. In Exp. 1, Angus heifers (n = 50) received a 7-d Ovsynch + progesterone protocol (on d 0, GnRH and progesterone insert were administered; on d 7, progesterone insert was removed and PGF2α was injec...
متن کاملتأثیر زمان های مختلف شروع پروتکل اوسینک پس از تلقیح بر شاخص های همزمانی و باروری گاوهای هلشتاین
The objective of this study was to consider effect of three different time of starting Ovsynch after Artificial Insemination, on synchrony parameters, pregnancy loss and fertility in Holstein cows. Multiparous cows (> 30 Kg/d, n = 450) randomly assigned to one of three groups. Groups according to time of starting Ovysnch were as follows: 1- Starting Ovsynch on day 25 after AI, 2- Starting Ovsyn...
