Cumulus-oocyte complexes (COCs) recovered during an ovum pick-up (OPU) session from
a cow is low (1 to 15 COCs). Moreover, mixing of two or more cows COCs to increase total …

Background The in vitro culture of presumed zygotes derived from single cow ovum pick-up
(OPU) is important for the production of quality blastocysts maintaining pedigree. The aim of …

Recovery of oocytes from live animals through ultrasound-guided transvaginal follicular
aspiration (ovum pickup, OPU) is an essential element of modern livestock development. To …

The first objective of this research was to compare the effect of single vs. group culture
methods on the developmental rate of oocyte maturation and embryo production in vitro …

A total of 901 cumulus–oocyte complexes (COCs) were collected from bovine ovaries
obtained at a local abattoir. COCs randomly assigned to Treatment I (n= 451), were cultured …

Bovine cumulus-oocyte complexes (COC)(n= 4230) were used in this study to assess the
effects of culture method, hormonal supplementation, and cumulus cell concentration on …

A new and effective protocol to culture bovine embryos without coculture and with
individualized culture media has been established, which would allow the study of a single …

Objective The objectives of this study were to elucidate the efficiency of oocyte recovery
through different techniques, grading of oocytes, and optimization of the caprine in vitro …

The experiment was undertaken to study the effect of collection techniques on cumulus
oocyte complexes (COCs) recovery, in vitro maturation (IVM) and in vitro fertilization (IVF) of …

The objective of this study was to evaluate the blastocyst development rate for in vitro
produced bovine embryos using either the conventional culture medium for bovine embryos …
