In vitro-produced blastocysts were transferred singly to 99 Angus crossbred recipients. Culture treatments were a 2 x 2 factorial of medium (KSOM or SOF) and oxygen concentration (5 or 20%). At parturition, birth weight and frame measurement before c

Blastocyst development, total cell number and allocation to inner cell mass (ICM) and trophectoderm (TE) lineages was compared among day 9 hatched blastocysts from four culture treatments in a two-factor design. Two modified commercial media (KSOM an

Timed embryo transfer (TET) using in vitro produced (IVP) embryos without estrus detection can be used to reduce adverse effects of heat stress on fertility. One limitation is the poor survival of IVP embryos after cryopreservation. Objectives of thi

We investigated the effect of meiotic stages and two maturation protocols on bovine oocyte's resistance to cryopreservation. Oocytes at germinal vesicle breakdown (GVBD) and metaphase II (MII) stage as well as oocytes matured for 22 h in media supple

Data on biopsied, sexed and cryopreserved in vitro produced (IVP) bovine embryos, and their in vivo developmental competence are very limited. Two preliminary studies were conducted before the primary study. In Experiment 1, post-thaw in vitro develo

A study was conducted to evaluate the potential of rescuing immature oocytes from the ovaries of an endangered wild bovid, the gaur (Bos gaurus). Recovered, immature gaur oocytes (n = 59) placed in culture were evaluated for: (1) nuclear maturation a

Microfluidics has shown promise as a new platform for assisted reproduction. To assess the potential of microfluidics for fertilization, we studied sperm and fluid motion in microchannels to better understand the flow characteristics in a microfluidi

The aim of this study was two-fold: (1). to compare recovery of embryos/ova from superovulated Holstein heifers by flushing the uterine horns through insertion of the catheter very close to the tip of the horn (deep) or just after the uterine bifurca

Cryopreservation causes a significant proportion of bovine oocytes to undergo degeneration during subsequent culture. We investigated the degeneration mechanism of cryopreserved oocytes. In vitro matured bovine oocytes were vitrified by the open-pull
