Use of Equine Pituitary Extract (EPE) in low doses to induce double ovulation in mares
(2017-01-01)
The aim of this study was to evaluate the effect of treatment using low doses of EPE on rates of ovulation and embryo recovery. Eight mares were used in this way: first cycle (n = 8)-control group (untreated); second cycle ...
Ovule bet-hedging at high elevation in the South American Andes: Evidence from a phylogenetically controlled multispecies study
(Blackwell, 2019)
How animal-pollinated plants support low and stochastic pollination in the high alpine is a key question in plant ecology. The ovule bet-hedging hypothesis proposes compensation for stochastic pollination via ovule oversupply ...
Ovule bet-hedging at high elevation in the South American Andes: Evidence from a phylogenetically controlled multispecies study

Ovulation and ovulation rate in ewes under grazing conditions: factors affecting the response to short-term supplementation
(2021-02-01)
The relationships between ovulation rate and nutrition remain confused, probably because of uncontrolled variation in experimental conditions. To help resolve the problem, we analyzed data from 20 experiments conducted ...
Is progesterone the key regulatory factor behind ovulation rate in sheep?
(Elsevier B.V., 2017-01-01)
Ovarian antral follicles in the ewe grow in an orderly succession, producing 3 to 4 waves per estrous cycle. In prolific sheep, some large antral follicles from the second-to-last wave of the estrous cycle are added to the ...
Ovulation rate and its relationship with follicle diameter and gene expression of the LH receptor (LHR) in Nelore cows
(Elsevier B.V., 2012-01-01)
The objective was to determine the relationship among the diameter of ovarian follicles, ovulation rate, and gene expression of the LH receptor (LHR) in Nelore cattle. In Experiment 1, ovulation was synchronized in 53 ...

The Use of hCG for Inducing Ovulation in Sheep Estrus Synchronization Impairs Ovulatory Follicle Growth and Fertility
(MDPI, 2021-04)
Currently, there is an intense effort to find an alternative hormone to eCG to induce ovulation after estrus synchronization treatments in sheep. One of the proposed alternatives is based on the use of hCG, but the results ...
