Clinical prospects proposing an increase in the luteolytic dose of prostaglandin F2α in dairy cattle

open access: yesThe Journal of Reproduction and Development, 2020
Over the past few decades, the luteolytic dose of prostaglandin F2α (PGF2α) and its analogs, used to synchronize estrus for fixed-time insemination in dairy cattle, have remained unchanged.

Does synchronising follicular wave emergence improve outcomes in non‐superstimulated donor cattle undergoing ovum pick‐up (OPU) for in vitro embryo production?

open access: yesAustralian Veterinary Journal, EarlyView.
In vitro embryo production (IVEP) is now a widely commercialised assisted reproductive technology used in cattle reproduction. The use of follicle‐stimulating hormone (FSH) to superstimulate donor cattle prior to ovum pick‐up (OPU) is generally regarded as an effective strategy to improve oocyte quality, developmental competence and increase embryo ...

Cortisol and heart rate response of mares during the in‐hand breeding procedure with and without restraint

open access: yesEquine Veterinary Journal, Volume 58, Issue 4, Page 1116-1126, July 2026.
Abstract Background In‐hand breeding involving restraint methods is likely the most common practice in the horse breeding industry worldwide. However, welfare issues that arise from such management have not been investigated in detail. Objectives (1) To investigate whether the mares show increased stress responses during in‐hand breeding using (a) a ...

Handmade Biopsy for Genotyping of In Vitro‐Produced Bovine Embryos

open access: yesAnatomia, Histologia, Embryologia, Volume 55, Issue 3, May 2026.
ABSTRACT Blastocyst biopsy allows genomic selection of pre‐implantation bovine embryos, reducing generation interval and enhancing the genetic gain. We aimed to evaluate the suitability of a simple biopsy procedure, performed by hands, using a splitting microblade and a stereoscope, on in vitro‐produced embryos. Crossbred Bos taurus x B.
