The aim of this study has been to attempt a phenotypic and morphological characterization of the stocks of the Casanare breed of cattle in the department of the same name in Colombia. To this end, we have studied 79 animals belonging to three farms considered to be those with a higher level of breed purity in their stocks. We took into consideration 24 phaneroptic and 23 morphological characteristics. On the basis of the results obtained, we have defined the first ever racial standard for this breed.
