The threshold of estradiol level for fresh embryo transfer differs between blastocyst and cleavage‐stage embryo [PDF]

Acta Obstetricia et Gynecologica Scandinavica
Introduction Ovarian stimulation can cause supraphysiological estradiol levels and adverse effects on endometrial receptivity. Since patients could undergo cleavage or blastocyst stage embryo transfer, the threshold value of peak estradiol level for each

Single-Step Genomic Prediction of Superovulatory Response Traits in Japanese Black Donor Cows

Biology, 2023
We assessed the performance of single-step genomic prediction of breeding values for superovulatory response traits in Japanese Black donor cows. A total of 25,332 records of the total number of embryos and oocytes (TNE) and the number of good embryos ...

Comparing Methods to Select Candidates for Re-Genotyping to Impute Higher-Density Genotype Data in a Japanese Black Cattle Population: A Case Study

Animals, 2023
As optimization methods to identify the best animals for dense genotyping to construct a reference population for genotype imputation, the MCA and MCG methods, which use the pedigree-based additive genetic relationship matrix (A matrix) and the genomic ...

Deslorelin Slow-Release Implants Delay Ovulation and Increase Plasma AMH Concentration and Small Antral Follicles in Haflinger Mares

Animals, 2021
There is an increasing interest in the manipulation of ovarian follicular populations in large domestic animals because this could prove beneficial for assisted reproductive techniques such as ovum pick-up (OPU).

The role of embryo transfer in improving pregnancy outcomes of in vitro fertilization-embryo transfer [PDF]

Xin yixue, 2022
Embryo transfer is not just a simple process of implanting the embryos into the uterus. A successful and effective embryo transfer requires not only high-quality embryos and appropriate uterine environment, but also high technical level of embryo ...

Influence of Intrauterine Fluid Detection, Number of Transfers and Age of the Recipient on Pregnancy Rate and Early Embryonic Loss in a Commercial Embryo Transfer Program

Animals, 2023
The selection of the recipient mare is one of the most important factors involved in the success of equine embryo transfer. The aim of this study was to determine whether the age of the recipient, the number of transfers and the detection of intrauterine

Expression of Enzymes Associated with Prostaglandin Synthesis in Equine Conceptuses

Animals, 2021
In the horse, mobility of the conceptus is required for maternal recognition of pregnancy depending on secretion of prostaglandins by the conceptus. The aim of this study was to determine the expression and localization of key enzymes of the different ...

Diestrous Ovulations in Pregnant Mares as a Response to Low Early Postovulatory Progestogen Concentration

Animals, 2020
Spontaneous prolongation of the luteal phase has been described in horses, but the underlying causes are still unclear. The present study investigated details of gonadotrophin and progestogen secretion in pregnant mares (n = 11) with or without ...
