The selection nucleus with early embryo transfer is designed for a systematic production of very young bull dams, evaluated from their 1st lactation following 2 embryo recoveries. Sire-son selection path is identical to that involved in conventional schemes.
With the present technical parameters for transfer, the superiority of this new scheme over conventional ones is already clear in closed populations and enhanced in populations opened to better foreign populations, due to a quicker diffusion of the superior foreign genes into the commercial population.
