FACTORS AFFECTING SUPEROVULATION, FERTILIZATION AND RECOVERY OF SUPEROVULATED OVA IN PREPUBERAL CATTLE [PDF]

open access: yesReproduction, 1970
Summary. Holstein calves, reared from birth under standard conditions, were given various combinations of pmsg-lh or pmsg-hcg at 8 to 9 weeks, or at 17 weeks of age. Follicular development was variable, but averaged fifty-three follicles≥1·0 cm in diameter following administration of either 1500 or 2000 i.u. of pmsg.

Abnormal early cleavage events predict early embryo demise: sperm oxidative stress and early abnormal cleavage. [PDF]

open access: yes, 2014
Human embryos resulting from abnormal early cleavage can result in aneuploidy and failure to develop normally to the blastocyst stage. The nature of paternal influence on early embryo development has not been directly demonstrated although many studies ...

Inhibition of Superovulation in the Rabbit [PDF]

open access: yesNature, 1953
THE horse pituitary extract AP.118.B induces superovulation in albino does at 12 weeks of age, provided the animals are fed at a high level from birth. Treatment consists of six subcutaneous injections of this pituitary extract at 12-hr. intervals, followed by an intravenous injection of 25 I.U. prolan 12 hr. later.

Welfare in horse breeding [PDF]

open access: yes, 2015
Welfare problems related to the way horses are bred, whether by coitus or by the application of artificial reproduction techniques (ARTs), have been given no discrete consideration within the academic literature. This paper reviews the existing knowledge

Cryopreservation of equine oocytes: looking into the crystal ball [PDF]

open access: yes, 2020
In vitro embryo production has evolved rapidly in the horse over the past decade, but blastocyst rates from vitrified equine oocytes remain quite poor and further research is needed to warrant application.

Effect of breed and follicular status on response to superovulation in South African goats

open access: yesJournal of Applied Animal Research, 2018
This study evaluated the effect of breed and follicular status of Boer and indigenous goats on response to superovulation and embryo yield. The oestrous cycles were synchronized with progestagen for nine days and superovulated with porcine follicle ...

Pertumbuhan Prenatal dalam Kandungan Kambing Melalui Superovulasi

open access: yesHayati Journal of Biosciences, 2007
Thirty six Etawah-grade does (BW 20.4-44.2 kg, age 2.5-7 years) were used to study the efficacy of increasing secretion of endogenous hormones of pregnancy by superovulation of does to stimulate of growth prenatal in uterus.

GnRH or estradiol benzoate combination with CIDR improves in-vivo embryo production in bovines (Bos indicus and Bos taurus) under subtropics [PDF]

open access: yesPeerJ, 2021
Multiple Ovulation and Embryo Transfer (MOET) technology is a potential technique to upgrade livestock species’ genetics. The varied response to super-stimulatory treatments remains one of the limiting factors to this technology’s widespread use.

Effect of Fsh β-Sub Unit and Fshr Genes Polymorphisms on Superovulatory Response Traits [PDF]

open access: yes, 2014
Follicle stimulating hormone (FSH) is a pituitary expressed glycoprotein hormone that regulatesreproduction in mammals which composed of α and β-sub unit. The β-sub unit dictates its bindingspecificity with their receptor (FSHR).
