DairyTalk 721: Better Genetics, More Difficult Calvings? Why OPU-IVP Can Change Calving Management - by Helmut Demmelhuber
This podcast episode is based on scientific and practical literature examining the biological consequences of OPU-IVP in cattle. Compared with artificial insemination and in-vivo embryo production, IVP pregnancies can be associated with longer gestation, heavier calves, and potentially more challenging calvings. Researchers are investigating mechanisms including epigenetic changes during early embryo development and altered placental function, while a direct link between IVP and premature birth remains uncertain. For breeding operations, this makes systematic recording of gestation length…
