Implanting cows with the embryos of genetically superior heifers is big business these days. It's helping elite cattle breeders and beef and dairy producers spread U.S. cow genetics around the globe.

Embryo transfer technology has revolutionized the breeding strategies, and if cattle producers are going to feed 9 billion people by 2050, there is no way they can rely on traditional breeding te ...

In 2017, Donahue was part of a team that performed Indiana’s first intravaginal embryo culture with an FDA-approved device that allowed embryos to grow in a device inside the patient rather than ...

UC Davis scientists spent years editing a sex-determining gene into bovine embryos using Crispr. In April, Cosmo arrived—and his DNA reveals how far the field has to go.

Implanting a beef cattle embryo in a dairy cow could increase profitability and cut greenhouse gas emissions. Male dairy calves are worth so little that they are often shot after birth, ...

American scientists have successfully created working kidneys from cells taken from cloned cow embryos, marking a leap forward towards the manufacture of spare-part organs from human stem cells.

The study, published in Biotechnology Journal, used genetic engineering techniques to integrate a human DNA segment that produces proinsulin into cows’ embryos.

But can the formation of such human-cow hybrid embryos be justified ethically? Not everyone agrees (Source: iStockphoto) Related Stories. Two mums plus dad made this embryo, Science Online, 06 Feb ...
