Embryo transfer (ET) is a recognized reproductive technology in food-animal production. It allows genetically superior females to make greater contributions to breeding programs. Also, appropriate processing of embryos recovered from animals infected with chronic viral and bacterial infections means those embryos can be transferred to healthy recipients with virtually no risk of disease transmission. Recovered embryos can be frozen for transfer at a future time or different location. The sale of embryos obtained from valuable donors represents an income stream for while breeders can retain ownership of their valuable donors.
