AMES, Iowa – Beef and dairy producers want the animals in their herds to possess the best genetics possible. But a cow can have only one calf per year, which places a natural limitation on how widely ...

Embryo development in livestock underpins global food security and genetic improvement programmes. From the first mitotic divisions in the zygote to the formation of the blastocyst, the timing, ...

Handmade cloning (HMC) presents several advantages over conventional cloning, including higher throughput, cost-efficiency, and operational simplicity. However, a comprehensive analysis comparing ...

Cornell researchers have uncovered the genetic triggers that cause male and female bovine embryos to develop differently, as early as seven to eight days after fertilization. The breakthrough in basic ...

AMES, Iowa – Iowa State University animal science and veterinary researchers made possible the first ever successful bovine embryo transfers in the Republic of Kosovo, paving the way toward improved ...

For decades, scientists knew that male embryos in many mammal species—such as cows, mice, and even humans—tend to grow faster than female ones. But no one really knew why. The new study, published in ...

The earliest days after fertilization, once a sperm cell meets an egg, are shrouded in scientific mystery. The process of how a humble single cell becomes an organism fascinates scientists across ...
