(Elsevier B.V., 2012-12-01)
This study aimed to determine whether deslorelin acetate could induce double ovulation in mares. In Experiment 1, eight mares were treated with prostaglandin on Day 8 (D8) after ovulation, then treated with saline or with ...
INDUCTION OF OVULATION AND OVARIAN CHARACTERISTICS OF PREPUBERTAL GILTS TREATED WITH HUMAN CHORIONIC GONADOTROPIN OR KISSPEPTIN
(Inst Zootecnia, 2016-01-01)
In view of its similar structure and function to luteinizing hormone (LH), human chorionic gonadotropin (hCG) has conventionally been used as the main hormone to induce estrus and ovulation in sows. Recently, it has been ...
Association of Deslorelin and Sulpiride for Double Ovulation Induction in Mares
(2018-11-01)
The aim of this study was to verify the effect of deslorelin and sulpiride association on double ovulation induction in mares. Ten mares were used for this study. Eight days after ovulation, luteolysis was induced and mares ...
Effect of superstimulatory treatments on the expression of genes related to ovulatory capacity, oocyte competence and embryo development in cattle.
(2012-12-01)
Multiple ovulation (superovulation) and embryo transfer has been used extensively in cattle. In the past decade, superstimulatory treatment protocols that synchronise follicle growth and ovulation, allowing for improved ...

(LIPPINCOTT WILLIAMS & WILKINS, 2010)
Purpose of review This review discusses ovarian reserve tests for ovulation induction and their application in determining fertility capacity, and their current applications to assess risk of natural ovarian failure and ...
Histrelin acetate-induced ovulation in Brazilian Northeastern jennies (Equus asinus) with different follicle diameters
(2019-09-15)
The aim of the present study was to evaluate the efficacy of a GnRH analog for induction of ovulation in Brazilian Northeastern jennies (Equus asinus) with different follicle diameters. Four consecutive estrus of 10 jennies ...
Embryo recovery and pregnancy rates after the delay of ovulation and fixed time insemination in superstimulated beef cows
(2002-04-01)

Comparative Efficacy of Histrelin Acetate and hCG for Inducing Ovulation in Brazilian Northeastern Jennies (Equus africanus asinus)
(2020-09-01)
The goal of this study was to compare the efficiency of histrelin acetate (GnRH analog) and human chorionic gonadotropin (hCG) to hasten ovulation in Brazilian Northeastern jennies (Equus africanus asinus). Thirty cycles ...
Progesterone-based strategies to induce ovulation in prepubertal Nellore heifers
(2013-01-01)
Four experiments were conducted to evaluate hormonal strategies to induce ovulation in Nellore heifers. In experiment 1, heifers (N = 1039) received a controlled internal drug release (CIDR) of fourth use (CIDR-4) on Day ...
Induction of multiple ovulations in mares using low doses of GnRH agonist Deslorelin Acetate at 48 hours after luteolysis
(Hippiatrika Verlag Mbh, 2015-03-01)
This study was aimed to test low doses of a GnRH agonist, deslorelin acetate (DA), for induction of multiple ovulations in mares and to determine its impact upon their reproductive efficiency. Seven mares aging from 8-20 ...
