Unlike most mammals, the mare does not have an increase of LH right before ovulation. FSH (Follicle-stimulating hormone): secreted by the pituitary, causes the ovarian follicle to develop. Levels of FSH rise slightly at the end of estrus, but have their highest peak about 10 days before the next ovulation.
Equine chorionic gonadotropin (acronym given as eCG but not to be confused with ECG) is a gonadotropic hormone produced in the chorion of pregnant mares.Previously referred to as pregnant mare's serum gonadotropin (PMSG), the hormone is commonly used in concert with progestogen to induce ovulation in livestock prior to artificial insemination.
The application of utilizing eFSH to increase the efficiency of equine embryo transfer was tested at the University of Saskatchewan.Embryos from 12 donor mares at 8 days of ovulation were recovered, scored, then transferred to 37 recipients mares who were tested for pregnancy after 7-10 days. 5 pregnancies resulted from the 15 embryos were recovered from the eFSA treatment group and 4 ...
Ovulation occurs about 109 hours after the start of follicle growth. Estrogen peaks at about 11 am on the day of proestrus. Between then and midnight there is a surge in progesterone, luteinizing hormone and follicle-stimulating hormone, and ovulation occurs at about 4 am on the next estrus day. The following day, metestrus, is called early ...
This test measures the amount of luteinizing hormone, a hormone that increases just before ovulation, that is in the urine. Before ovulation, the luteinizing hormone levels dramatically increase; this is known as the "LH surge". This test can recognize the LH surge about 1-1.5 days prior to ovulation. Additionally, some ovulation prediction ...
This positive feedback loop causes LH to spike sharply, and it is this spike that causes ovulation. Following ovulation, LH stimulates the formation of the corpus luteum. Estrogen has since dropped to negative stimulatory levels after ovulation and therefore serves to maintain the concentration of FSH and LH.
Induced ovulation is the process in which the pre-ovulatory LH surge and therefore ovulation is induced by some component of coitus e.g. receipt of genital stimulation. Usually, spontaneous steroid-induced LH surges are not observed in induced ovulator species throughout their reproductive cycles, which indicates that GnRH release is absent or ...
Techniques were developed where the implant was removed 48 hours after implantation in the mare, [8] however compounded biorelease Deslorelin products were at the time available as well as more commonly used ovulation promoters such as hCG, which did not produce the same failure effect. Upon "Sucromate Equine" receiving FDA-approval, the ...
