Continuous observation of embryonic growth can improve understanding of the early developmental events and allow us to use parametric statistical analyses with time as a parameter. A cinematographic study such as that reported here utilizes time-laps

The viability of microblade-bisected Day-7 embryos transferred to recipients without zona pellucidae directly after splitting or after overnight storage at 4°C was investigated in two experiments. In Experiment 1, 26 demi-embryos of excellent or goo

The aims of this study were to evaluate the amount of amniotic fluid required for diagnosis of sex, milk protein and microsatellite variants by polymerase chain reaction (PCR) and to review methods for isolating DNA from the amniotic cells. Uterine a

In this study we evaluated the use of a chemically defined medium in the production of blastocysts from bovine oocytes fertilized in vitro. As culture medium we used CRI-PVP, a modification of CRlaa medium with bovine serum albumin replaced by polyvi

Morula and blastocyst stage embryos recovered from B6D2F_1 mice were bisected with a metal microblade in M2 medium with or without sucrose and/or cytochalasin B supplementation. Cell lysis was determined by staining the embryos with Hoechst 33258 and

The effect of alanine (1 mM) and glycine (10 mM) supplementation on bovine embryo development in vitro was investigated. Presumptive bovine zygotes, produced by in vitro maturation and insemination of oocytes, were cultured for 144 h in CRlaa medium

4’,6’-diamidino-2-phenylindole (DAPI) is a fluorescent dye that binds only to the DNA of dead blastomeres of an embryo. The use of DAPI for assessing viabilities of equine Day 6 to 7 embryos was studied. The pregnancy and normal development of th

A PCR-based sex determination assay for sheep and cattle embryos was developed using mouse embryos for optimizing the protocol. Samples were lysed either enzymatically or by alkaline treatment followed by enzymatic amplification of DNA from the ZFY/Z

Multiple ovulation embryo transfer (MOET) is used to make more rapid progress in animal breeding schemes. On dairy farms, where female calves are more desired, embryo sex diagnosis is often performed before embryo transfer. Fresh transfers have been
