Embryo Transfer Can Maximize Best Genetics
Heather Smith Thomas
A growing number of breeders now use advanced reproductive techniques such as embryo transfer (ET) to maximize the genetics of their best cows. This is a way to produce many more calves from an outstanding cow than she could ever raise in her lifetime. As pointed out by Russ Princ at Genex (a company that does custom semen collection, much of which is used for ET), this is also a way to get more calves from a pair of animals that nick well. “A good cow may have only 10 to 14 calves during her life, but with ET you can raise dozens of calves from her. People are selling rights to flushes, selling embryos, and confirmed sexed pregnancies (in recip cows) from a flush,” says Princ.
