Castúa sow Program and the future of the Iberian pig
Castúa sow program is an applied research work financed by CDTI and Inga Food, and developed with the participation of IRTA and the collaboration of the University of Zaragoza and the University of Extremadura. The research, of a vast magnitude, is intended to provide the Iberian pig sector with a highly productive, high-quality and homogeneous animal, selected with objective criteria through modern genetics tools.
The work carried out during these years has had two central pillars. On the one hand, the study and genetic-productive analysis of three of the most important Iberian breeds swine (Retinto, Entrepelado, Torbiscal), and their ability to cross in purity among them, for the use of heterosis and its complementarity in the different characters (reproductive, productive, quality of carcass and meat).
On the other hand, once it had been chosen the two more suitable breeds, and fixed its position in the Castúa chart, a Genetic Selection and Improvement Plan was implemented for each one of them according to its “selection objectives”.
The breed’s purity, the rigor in the bloodline control, in the zootechnical data collection, and the health control, together with an adequate feeding system adapted to the nutritional requirements of the Iberian pig of the Castúa Program, in addition to the use of the newest technologies in genetic improvement and management of swine production, are the strategic aims in which the success of the Castua Progam is based.
