Intermountain Embryonics was started by veterinarians Hoyt Rees and Rebecca Holmbeck in June of 2017. Now that IVF technology has become affordable and efficient, it is Intermountain Embryonic's goal to help beef and dairy producers capitalize on this technology. Through rapid genetic improvement that embryo use can provide, producers can increase production rates, improve animal health traits, and increase feed efficiency. Genetically superior animals can produce more with less, making animal agriculture more profitable, while reducing stress on the environment.
