AI Article Synopsis
- Early embryonic pregnancy losses in beef and dairy cows are often linked to developmental issues occurring during various stages, especially with in-vitro-produced embryos.
- The review covers critical stages like oocyte maturation, fertilization, and early embryonic development, highlighting common problems encountered and their impact on pregnancy outcomes.
- While some potential solutions are explored, many issues currently lack effective corrective measures, indicating a need for further research to enhance the survival rates of bovine embryos to term.
Article Abstract
Several key developmental events are associated with early embryonic pregnancy losses in beef and dairy cows. These developmental problems are observed at a greater frequency in pregnancies generated from in-vitro-produced bovine embryos. This review describes critical problems that arise during oocyte maturation, fertilization, early embryonic development, compaction and blastulation, embryonic cell lineage specification, elongation, gastrulation, and placentation. Additionally, discussed are potential remediation strategies, but unfortunately, corrective actions are not available for several of the problems being discussed. Further research is needed to produce bovine embryos that have a greater likelihood of surviving to term.
