The oxytocin receptor, luteolysis and the maintenance of pregnancy [PDF]
Bioscientifica Proceedings, 2019 During luteal regression episodic pulses of oxytocin secretion become coupled to the release of prostaglandin F2 alpha (PGF2 alpha) following synthesis of endometrial oxytocin receptors, but in early pregnancy the inhibition of oxytocin receptor formation by the conceptus prevents the development of the pulsatile pattern of PGF2 alpha release needed to

Luteal haemodynamics during spontaneous and induced luteolysis in crossbred cattle
Indian Journal of Animal Sciences, 2022 The haemodynamics of CL during natural and induced luteolysis was studied in crossbred cattle using colour Doppler ultrasonography. In natural cycle, penetration of Doppler signals deep into the CL was observed during Day 15 – 17 coinciding with the ...

Journal of Dairy Science, 2022 : Objectives were to evaluate the effect of 2 analogs of PGF2α (cloprostenol vs. dinoprost) and 2 doses (1 injection vs. 2 injections) on luteolysis, follicle diameter, hormonal concentrations, and time to ovulation in dairy heifers.

Table_1_The Interaction Between Nodal, Hypoxia-Inducible Factor 1 Alpha, and Thrombospondin 1 Promotes Luteolysis in Equine Corpus Luteum.DOCX [PDF]
, 2019 The regulation of corpus luteus (CL) luteolysis is a complex process involving a myriad of factors. Previously, we have shown the involvement of Nodal in functional luteolysis in mares.

Macedonian Veterinary Review, 2020 We hypothesized that a single dose of PGF2α belatedly injected on day 8 after GnRH-1 in cows receiving a 7-day Ovsynch-56 protocol (GnRH – 7 days – PGF2α – 56h – GnRH – 16h – timed AI) will increase the proportion of cows with complete luteolysis. At day

Review: Luteal prostaglandins: mechanisms regulating luteal survival and demise in ruminants
Animal, 2023 The corpus luteum (CL) is critical for establishment and maintenance of pregnancy in all mammals. However, the fate of the CL in ruminants is dependent on the presence of a functional uterus or signals from a developing embryo to modify uterine function ...

Journal of Animal Breeding and Genetics, EarlyView.ABSTRACT The Finnish Ayrshire cattle belong to the Nordic Red breeds. The basis of selection in Nordic Red breeds shifted from traditional pedigree‐based breeding values to genomic breeding values between 2011 and 2014. Joint genetic evaluation and admixture among the Nordic Red breeds have led to the formation of a composite Nordic Red population ...

Animals, 2021 This study examined the dose–response effect of prostaglandin F2α (PGF2α) when used to induce abortion in cows with two dead twins at pregnancy diagnosis 28–34 days post-AI (late embryonic period: LE) or at pregnancy confirmation 49–55 days post-AI ...

Molecular Reproduction and Development, Volume 93, Issue 7, July 2026.This graphical abstract summarizes that dietary supplementation of pregnant beef cows with unsaturated fatty acids and choline can increase (green) the concentration of metabolites in the uterine luminal fluid and alter the endometrial epithelial transcriptome during the peri‐elongation period (upregulation = green and downregulation = red).
