Abstract

Bovine oocytes from prepubertal donors have been used for in vitro embryo production to decrease the generation interval. However, reduced cumulus-oocyte competence, mainly attributed to increased apoptosis, has been observed in oocytes/embryos collected from prepubertal donors. Here, we...

Abstract

Treatments with follicle stimulating hormone (FSH) to enhance ovarian follicular development before ovum pick-up (OPU) are important for improving in-vitro embryo production (IVEP) procedures in cows, however, their procedural efficacy needs to be evaluated. The objective of the present study was...

Abstract

Cows were treated with follicle-stimulating hormone (FSH) in a single dose and then subjected to ovum pick-up (OPU) for evaluation of oocyte recovery and in vitro fertilization (IVF). Cows underwent OPU followed by application of FSH (200 mg) on day 2 and new OPU on day 3. This methodology was...

Abstract

This study was conducted to evaluate oocyte recovery and in-vitro blastocyst production of donor cows superstimulated for ovarian follicular development with FSH administered as twice-daily injections in saline or a single injection diluted in 0.5% hyaluronan before oocyte aspiration. In Experiment ...

Abstract

Cows treated with single doses of follicle stimulating hormone (FSH) and ovum pick up (OPU) after 24 hours were evaluated for oocyte recovery, in vitro production of embryos (IVPE), and transferred embryos. To begin evaluations, the ovarian follicles larger than three millimeters in diameters were...

Abstract

The objective of this experiment was to evaluate the impact of complexed trace mineral supplementation on ovum pick-up (OPU) and in vitro embryo production in lactating beef cows. Thirty days prior to fixed-time artificial insemination (FTAI; day -30), 68 postpartum cows were stratified by BW, BCS, ...

Abstract

In the present study, there was an evaluation of in vitro embryo production (IVEP) in Bos indicus donor cows with small or large antral follicle counts (AFCs) when there was synchronization of follicular dynamics among cows before ovum pick-up (OPU). Donor cows classified as having small or large...

Abstract

The hypothesis of this study was that cows with good genetic merit for fertility traits (Fert+) would produce oocytes and embryos of greater quality than cows with poor genetic merit for fertility traits (Fert-) and that mRNA expression of candidate genes would reflect the observed differences in...

AbstractFull Text

The aim of this study was to compare the capacity of embryonic development of oocytes recovered from slaughterhouse ovaries and recovered in vivo by guided ultrasound (ovum pick-up - OPU) in an in vitro production system. Nine sessions in 59 Holstein cows were done to obtain oocytes through OPU and ...

Abstract

The differential expression of many productive and reproductive traits has already been associated with the genotype effect observed between Bos taurus indicus (Bos indicus) and Bos taurus taurus (Bos taurus) breeds. Lipids have a crucial role during oocyte development. The aim of this work was to...
