    The purpose of this study was to establish the differences in morphometric characteristics of the cows with the Mottled Creole biotype versus the mestizo biotypes existing in the area. For this purpose, a descriptive, non-experimental, field study with a cross-sectional and quantitative approach was implemented. A population of 30 animals of the Criollo Jaspeado biotype and 30 mestizo animals with taurine crossbreeding, belonging to the Boyacá parish, Chone canton, province of Manabí, at 52 meters above sea level, were evaluated. The variables evaluated were height, body condition, weight, hoof angle, pelvic contour, length and width of vulva, width of ileum and ischium, length and diameter of teats. Among the outstanding results, there were significant statistical differences between the two groups of cattle for the body condition variable, with better performance for the variable in the Creole Marbled biotype cattle, despite the fact that the study was carried out during the dry season of the year. It is evident that this type of cattle maintains an optimal body condition in spite of the irregular topography, dry tropical climate, pasture limitations, distant access to water and presence of pests. Similarly, no significant statistical differences were found for the variable height and weight in kilograms. In the case of productive characteristics, there were no significant statistical differences for hoof angle, pelvic contour, vulva length and width, ileum and ischium width and teat length. However, the teat diameter variable generated significant statistical differences, based on the genetic predisposition with dairy aptitude of cattle with the Criollo Jaspeado biotype. It is demonstrated that cattle with the Criollo Jaspeado biotype are capable of competing in meat structure and dairy aptitude with the Brahman and Gyr dairy crossbreeding existing in the area.
