Short communication: JY-1 gene variants and embryo production in Holstein cows
(2021-02-01)
The aims of this study were to verify the occurrence of single nucleotide polymorphisms (SNPs) in the JY-1 gene and their association with the in vivo and in vitro production of embryos in Holstein donors. The JY-1 protein ...
Morphology, sex ratio and gene expression of Day 14 in vivo and in vitro bovine embryos
(2013-04-29)
The present study was designed to compare Day 14 bovine embryos that were produced entirely in vitro using the post-hatching development (PHD) system with in vivo-derived embryos without or with transient PHD culture from ...
Morphology, sex ratio and gene expression of Day 14 in vivo and in vitro bovine embryos

Forskolin effect on the cryosurvival of in vitro-produced bovine embryos in the presence or absence of fetal calf serum
(Cambridge University Press, 2014-05-01)
The objective of this study was to assess the viability and cryotolerance of zebu embryos produced in vitro with or without the addition of fetal calf serum (FCS) and forskolin (F). Embryos produced in vivo were used as a ...
Vitrified embryo transfer in Merino sheep under extensive conditions
(Colégio Brasileiro de Reproducao Animal, 2019-06)
The aim was to evaluate pregnancy success after transfer of embryos vitrified in micropipette tips in Merino sheep under extensive conditions. A second objective was to evaluate the influence of embryo stage in such pregnancy ...
Comparison of embryo yield and pregnancy rate between in vivo and in vitro methods in the same Nelore (Bos indicus) donor cows
(Elsevier B.V., 2009-03-01)
To investigate why the preferred means to produce bovine embryos in Brazil has changed from in vivo to in vitro, we compared these two approaches in the same Nelore cows (n = 30) and assessed total embryo production and ...
