Abstract
This research contributes to the study of the Guatemalan Creole pig. It has included the study of 66 animals from three different communities of the Ch'ortí region, in Chiquimula, on which we analysed 12 quantitative traits: face length, head length and width, withers and rum heights, body length, dorsoesternal height, bicostal and rump widths, rump length, chest and cannon perimeters. From obtained results it can be considered this breed as monomorphic. The lack of sexual dimorphism found in this work could be the result of: 1) no differential expression of hereditary characters between sexes, or 2) a consistency with Bergmann's rule. For possible biotypes, the breed does not present differences in morphological appearance, whatever genetic lineages and environmental conditions of each geographical area. Results may be of special value for considering possible breeders exchanges.
