Objective: to characterize and genetically evaluate the Holstein population located in the high tropics of Nariño province, Colombia, in order to propose an improvement program that meets the region's needs and conditions. Methods: first, values of heritability (h²), repeatability (R), and genetic correlations (Г) between milk production (PL), milk fat percentage (PG), milk protein percentaje (PP), open days (DIAB), number of services per conception (SPC), calving interval (IEP), and several shape or phenotypic variables were estimated. Historical information was collected from 296 farms between 1999 and 2006. Subsequently, the milk production control was conducted until 2010. An Animal Model was used to estimate the genetic parameter...
