Follicular dynamics and ovulation time in gilts and post-weaning sowsDynamique folliculaire et moment de l’ovulation chez les cochettes et les truies en période post-sevrage
(Canadian Vet Med Assoc, 2017-01)
Ultrasonography was used to study follicular dynamics from the beginning of estrus to ovulation in pubertal gilts and post-weaning sows. Ultrasound turned out to be a useful tool to determine patterns of growth of preovulatory ...
Induction of double ovulation in mares using deslorelin acetate
(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 ...
Inducing ovulation with oestradiol cypionate allows flexibility in the timing of insemination and removes the need for gonadotrophin-releasing hormone in timed AI protocols for dairy cows
(Csiro Publishing, 2017-01-01)
The effects of addition of gonadotrophin-releasing hormone (GnRH) to a progesterone plus oestradiol-based protocol and timing of insemination in Holstein cows treated for timed AI (TAI) were evaluated. Cows (n=481) received ...
Development and fate of the postovulatory follicle complex, postovulatory follicle, and observations on folliculogenesis and oocyte atresia in ovulated common snook, Centropomus undecimalis (Bloch, 1792)
(2017-04-01)
The common snook, Centropomus undecimalis, was induced to ovulate using a time-release, GnRH analogue. Ovulation occurred the afternoon or evening the day after hormone administration. The time of ovulation was established ...
Use of estradiol benzoate to induce ovulation in a short-term protocol for fixed-time AI in sheep
(2015-01-01)
The aim of this study was to test the hormonal protocol for fixed-time artificial insemination (TAI) with a progesterone vaginal device for six days applying equine chorionic gonadotropin (eCG) or estradiol benzoate (EB) ...
Ovule, fruit and seed development in Abolboda (Xyridaceae, Poales): implications for taxonomy and phylogeny
(Wiley-Blackwell, 2014-05-01)
Xyridaceae belongs to the xyrid clade of Poales, but the phylogenetic position of the xyrid families is only weakly supported. Xyridaceae is divided into two subfamilies and five genera, the relationships of which remain ...
