The uteri of two donor female llamas were flushed non-surgically and one viable 7-day-old embryo was recovered. The embryo was transferred non-surgically within four hours into a recipient female llama whose estrous cycle was synchronized with the donor by injection of gonadotropin releasing hormone (GnRH). Pregnancy was confirmed 20 days after transfer, at which time the level of serum progesterone was determined and found to be consistent with that of gestation (>/=100 ng/100 ml). A normal and healthy male weighing 33 1bs was born on October 8, 1984, 326 days following transfer of the embryo to the recipient.
