El dimorfismo sexual de tamaño (SSD) es un fenómeno poco estudiado en las razas domésticas locales, y generalizaciones como la regla de Rensch, que interpreta la relación del SSD con el tamaño corporal, no han sido siempre fundamentadas para las diferentes especies de ganado. Se escogió para esta investigación una representación de razas de cerdos criollos para realizar un estudio comparativo del SSD debido a su homogeneidad morfológica, características reproductivas y rango de tamaños. Los resultados reflejaron una isometría en la relación del tamaño sexual, al menos para el caso de las razas criollas estudiadas. Pero son necesarios un mayor número de estudios a nivel intraespecífico para evaluar la variación geográfica de tamaño y su impacto sobre el SSD, así como para poder comprender los mecanismos que modulan el SSD.
Sexual dimorphism in size (SSD) is a phenomenon scarcely studied among local domestic breeds, and generalizations such as the rule of Rensch, which interprets SSD relationship with body size, have not been always informed for livestock. Creole pig breeds were chosen for this SSD comparative study due to their morphological homogeneity, their reproductive characteristics and their size range. The results reflected an isometric sexual size relationship, at least for studied creole pigs. But a greater number of studies at the intraspecific level in this species are needed to assess the geographic variation in size and its impact on the SSD, as well as to understand the mechanisms that modulate the SSD.
