The elaboration of strategies in the field of conservation of animal genetic resources (and not only) had, have and will be based on genetic analysis studies. Without conducting these studies, it is practically impossible to develop management strategies for inbreeding or to develop effective breeding programs. In this paper we present two important indicators of genetic analysis in horse population and not only the reproductive isolation coefficient and the age structure. This parameter has a capital importance in animal breeding because there has a directly influence in animal population evolution. More than that, To be accepted as a population, a herd must fulfill four criteria: reproductive isolation, morphological and physiological differences, environmental requirements and genetic size. The reproductive isolation is the most important criteria for population because only reproductive isolated populations have an own evolution. Regarding the age structure, this parameter has a double importance: for exploitation (influenced directly average age), and on the other hand, for animal breeding (influenced the generation interval and population variability).
