Resumen: The studbook of the Spanish Arab Horse was analysed in order to assess the available genetic variability in the population via genealogical analyses and to ascertain the influence of different countries in the formation of the population. The Spanish Arab horse studbook could be traced back to the late 19th century with a total of 18,880 animals. A 15.7% (2965) of the registered individuals were Arab horses imported from foreign populations. The total number of founders was 1626: from these, 1495 individuals were identified as imported from foreign countries. The sum of the genetic contributions of the founders to the population revealed that those imported from the ‘Middle East’, Poland, the United Kingdom and Egypt had a higher importance in the formation of the Spanish Arab Horse, contributing, respectively, 36.4%, 18.7%, 11.9% and 9.1% of the genetic variability. The effective number of founders was 38.6 and the effective number of ancestors was 19 thus characterising the a...
