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 ...
Influence of milk production on conception following artificial insemination or embryo transfer in lactating Holstein cows
(Amer Soc Animal Science, 2004-01-01)
Equine cloning: In vitro and In vivo development of aggregated embryos
(Society For The Study Of Reproduction, 2012-07)
The production of cloned equine embryos remains highly inefficient. Embryo aggregation has not yet been tested in the equine, and it might represent an interesting strategy to improve embryo development. This study evaluated ...
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 ...
Reduction in cytoplasmic lipid content in bovine embryos cultured in vitro with linoleic acid in semi-defined medium is correlated with increases in cryotolerance
(Cambridge University Press, 2015-09-09)
We examined whether culturing embryos with linoleic acid (LA) in semi-defined medium reduces lipid accumulation and improves cryosurvival after vitrification. Embryos were cultured with LA (100 μM) and a semi-defined medium ...
Non-surgical embryo transfer in goats and sheep: the Brazilian experience
(Csiro Publishing, 2019-01-01)
Brazil has presented tremendous progress in non-surgical embryo transfer (NSET) in sheep and goats. New instruments and techniques for non-surgical embryo recovery (NSER) and NSET in small ruminants were implemented. Recent ...
Which Factors Affect Pregnancy Until Calving and Pregnancy Loss in Buffalo Recipients of in vitro Produced Embryos?
(Frontiers Media Sa, 2020-12-02)
In vitro embryo production and embryo transfer (ET) in buffaloes has been developed for decades. However, most studies are focused on the donor or laboratory improvements, and there is a lack of reports regarding the ...
Update and overview on assisted reproductive technologies (ARTs) in Brazil
(2016-01-01)
The impressive increase in the use of assisted reproductive technologies (ARTs), especially in cattle, during the last few years in Brazil is well known worldwide. In 2015, there were over 13.7 million artificial inseminations ...
