At the Hacienda Cuba, located in the municipality of Montelíbano, Córdoba, 22 Bradford and Brangus cattle were born, after receiving females received an embryo transfer.

In the IPS CES Sabaneta, in the laboratory of the Colombian Institute of Tropical Medicine (ICMT) the embryos were incubated in vitro that were transferred to the recipient females and that nine months later would give life to these high-quality breed bovines.

The embryo transfer project with high genetic selection began in 2017, it was started by the CES University in an agreement with the Fundación Nuestra Señora de los Desamparados (FNSD) - Hacienda Cuba and the reproductive biotechnology company Ge3

"This project seeks to produce high-selection cattle to have them as the basis of our undergraduate and graduate practices and also serve for the selection and insemination of high-quality cattle among our associates" , mentioned the dean of the Faculty of Veterinary Medicine and Zootecnia (MVZ), Jhon Didier Ruiz Buitrago.

To carry out this transfer, the embryos are produced in vitro with ovules from females with high genetic potential and also with spermatozoa from highly selected bovines. Then some females are selected that are called receptors where hormonal management is done to simulate that they are pregnant without being pregnant and in the next phase of the process the embryo is implanted. The characteristics of the receiving females is that they have good body condition, that when it comes to raising good milk and that they have an ease of calving.

Between 40% and 50% of the transfers can be successful and the cattle that are born 9 months later do not have any genetic material from the recipient female.

"On November 9, another 26 recipient females were transferred and we are waiting to confirm how many of these females we have pregnant," added Alexandra Úsuga Suárez, professor of Animal Reproduction and Biotechnology at the MVZ Faculty of Veterinary Medicine and Zootechnics.

Five bovines resulting from the embryo transfer will arrive at Villa Elisa, one of the practice centers of the Faculty of Veterinary Medicine and Zootechnics, in November.
