Paradoxical effects of bovine somatotropin treatment on the ovarian follicular population and in vitro embryo production of lactating buffalo donors submitted to ovum pick-up
(Elsevier B.V., 2015-03-01)
The aim of the present study was to evaluate the effect of bovine somatotropin (bST; 500 mg) administration on lactating buffalo donors submitted to two different ovum pick-up (OPU) and in vitro embryo production schemes ...
Number of oocytes retrieved per donor during OPU and its relationship with in vitro embryo production and field fertility following embryo transfer
(2017-01-01)
The association of OPU-IVEP is an important instrument to drive genetic progress. In vitro embryo production (IVEP) has remarkably expanded in the last decade compared to in vivo embryo production. Because of the high ...
Differential expression of members of the IGF system in OPU-derived oocytes from Nelore (Bos indicus) and Holstein (Bos taurus) cows
(2013-05-01)
The insulin-like growth factor (IGF) system is related to quality of oocytes and embryos. The aim of this study was to investigate the mRNA levels of IGF1 and IGF2 and their receptors, IGFR1 and IGFR2, as well as IGFBP2, ...

Produção in vitro de embriões bubalinos
(2011)
Recently, buffalo in vitro embryo production presents high maturation rate (80%), moderate cleavage rate (50%), and moderate blastocyst formation rate (20%). IVP has a great potential to advance bubalinoculture as much as ...
Effect of recombinant bovine somatotropin (bST) on follicular population and on in vitro buffalo embryo production
(Elsevier B.V., 2009-06-01)
The objective of this study was to evaluate the effect of bovine somatotropin (bST) on ovarian follicular population in buffalo heifers and its influence on oocyte quality, recovery rates and in vitro embryo production. ...
Characterization and control of oocyte large-scale chromatin configuration in different cattle breeds
(Elsevier B.V., 2020-01-01)
Differences in reproductive physiology between cattle breeds may help to explain distinct responses to assisted reproductive techniques and to define breed-specific protocols with improved efficiency. Germinal vesicle (GV) ...
