The present study made a diagnosis of the distribution of sheep breeds and crosses, from the regions of Coquimbo to Magallanes y Antártica Chilena, by number, sex and age. Data was collected through surveys included sheep producers, slaughterhouses and livestock markets, and supplemented with information provided by the Seventh Chilean Agriculture and Forestry Census, 2007. The study found that the surveyed regions has a total of 25 breeds and 6 commercial crosses, and crossbreeds made by sheep producers to obtain animals with higher productivity. The major breeds, and their respective participation within the national fock, are: Corriedale (74%), mainly present in the southern regions; Suffolk 6%, mainly in the central zone; and Australian Merino, with 3%, in the central north and austral zones. The crosses made by sheep producers represent 12% of all sheep. Only a small proportion of sheep sales are through livestock markets, and in general most regions of the country lack authorized slaughterhouses to process sheep. Cold storage facilities occur south of the Bio Bio region, and the bulk of local production is consumed by the domestic market. Se realizó un diagnóstico de la distribución del recurso genético ovino, desde las regiones de Coquimbo a Magallanes y Antártica Chilena, destacando las razas y cruzas ovinas por número, sexo y edad. Los datos fueron recopilados a través de encuestas, aplicadas a productores ovinos, plantas procesadoras, frigoríficos y ferias ganaderas; complementados con la información aportada por el VII Censo Agropecuario y Forestal del año 2007. El estudio señaló que en las regiones encuestadas un total de 25 razas, seis cruzas comerciales y diferentes cruzas realizadas por los productores ovinos. Las principales razas son: Corriedale con un 74% de existencia, principalmente en la Zona Austral; Suffolk Down, 6%, principalmente en la Zona Central; y Merino Australiano con un 3%, en la Zona Centro Norte y Austral del país. Los cruces realizados por los productores ovinos, representan ...
