At the end of January 2007, was born in Brasilia the first calf clone resulted of the technical partnership among BIO, the Laboratory of Biotechnology of Reproduction and Embryology of the Veterinary Medicine Faculty– UFRGS, led by Prof. Dr. Jose Luiz Rodrigues and Central Caiapó, owned by Dr. João Pimenta da Veiga Filho. Affectionately called Fabi, the calf is a product of the Nuclear Transfer technique. In this work, the cloned embryos were gotten using electron-fusion of stem cells, obttanined from adipose tissue of an important cow of Nelore sire, with cytoplasms from enucleated oocytes. After 7 days of in vitro culture, the cloned embryos were transferred to the recipient heifers at Central Caiapó. The calf was born clinically well, at 289 gestation days and it had around 35 kg.
