This study was an investigation of metabolism during bovine preimplantation development
from the oocyte up to the hatched blastocyst derived in vitro or in vivo. Metabolism was …

The consumption of oxygen, uptake of pyruvate and glucose and production of lactate were
determined for groups of bovine embryos produced in vitro from the one-cell to the …

Simple media were developed to study the metabolic requirements of bovine embryos up to
Day 7 (Day 0= day of oocyte aspiration) in vitro. Embryos were derived from oocytes …

The consumption of pyruvate and glucose, and the production of lactate, by single
preimplantation embryos, was measured using a noninvasive technique. Embryos were …

Pig embryos were collected, 2–7 days after oestrus, in modified BMOC-2 containing glucose
as the only energy source. Embryos were incubated individually in medium containing [5-3 …

Embryos were collected from superovulated donors at various intervals from onset of
oestrus, ranging from Day 1.5 to Day 6. In addition, blastocysts obtained from the culture of 1 …

Glucose utilization by sheep embryos was examined in 8‐cell (N= 36) and blastocyst (N=
36) stages, by measuring conversion of [5− 3H] glucose to 3H2O. Fifty percent glucose …

The metabolism of radiolabelled glucose and glutamine was measured in individual cattle
embryos produced by in vitro maturation and fertilization of oocytes, and culture with bovine …

At the beginning of the 1990s, co-culture of cattle and sheep embryos was the most favoured
method to support embryo development, but the use of this system has hampered progress …

The uptake of pyruvate and glucose by individual sheep oocytes and preattachment sheep
embryos at each state of development up to the hatching blastocyst was determined using a …
