Abstract
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.
