Abstract
El cerdo ibérico, perteneciente al tronco porcino Sus scrofa meridionalis o cerdo mediterráneo, ha sido criado en sistemas extensivos durante siglos y como consecuencia, ha desarrollado un genotipo “ahorrador” que le permite adaptarse a las condiciones climáticas extremas y a los ciclos estacionales de abundancia y escasez de alimento característicos del suroeste de la Península Ibérica. Por otro lado, la rusticidad propia de la raza y la escasa selección genética determinan una menor eficiencia de sus parámetros productivos respecto a otras razas cosmopolitas seleccionadas. Sin embargo, en los últimos años, la demanda de productos cárnicos de calidad por parte de los consumidores ha llevado a la intensificación de los sistemas de producción del cerdo ibérico. Los sistemas intensivos aumentan la rentabilidad del proceso productivo, ya que permiten acortar los ciclos de producción y reducir los meses de vida para alcanzar el peso mínimo de sacrificio. Sin embargo, existen marcadas diferencias en la eficiencia de la producción del cerdo ibérico respecto a las razas mejoradas, siendo las más evidentes la menor precocidad y mayor duración del ciclo productivo en el cerdo ibérico...
The Iberian pig, which belongs to the Sus scrofa meridionalis or Mediterranean pig type, has been raised for centuries in extensive systems and as a consequence, it has developed a "thrifty" genotype that allows it to adapt to extreme climatic conditions and seasonal cycles of abundance and scarcity of food, typical of the southwest Iberian Peninsula. On the other hand, the breed's rusticity and the scarce genetic selection determine a lower efficiency of its productive parameters compared to other selected cosmopolitan breeds. However, in recent years, consumer demands for quality meat products has led to the intensification of Iberian pig production systems. Intensive systems increase the profitability of the production process, as they shorten production cycles and reduce the months of life to reach the minimum slaughter weight. However, there are marked differences in the efficiency of the production of the Iberian pig with respect to improved breeds, the most evident being the shorter precocity and longer duration of the production cycle in the Iberian pig...
