T. P. S.  aBrazilian pantaneiro horsebgenetic diversity at microsatellite level.  c2003  aBrazilian Pantaneiro Horse was originated from horses introduced by Spanish and Portuguese colons about three centuries ago. This population was selected to resist the adverse conditions of the environment and now is submitted to a conservation program where DNA typing will be an important tool to help in the management and control "in situ" conservation nucleus of Embrapa Pantanal farm. An analysis of 12 microsatellite loci in 101 animals has been used to define the genetic strucuture of the Pantaneiro Horse from Brazil. Nei's DA distances from Thoroughbred, Arabian, Spanish Pure Breed (Andalusian) and Uruguay Creole horses were calculated showing a minimum distance of Pantaneiro Horse and Spanish Pure Breed (0.228) and similar distance from Spanish Pure Breed and Thoroughbred and Arabian (0.355 and 0.332). Resulta indicate a great diversity level, clear distancing respect to the other breeds and genetic uniformity inside the Pantaneiro Horse. Finally we suggest the utilisation of genetic for genealogical registers control, conservation plans and Pantaneira breed management.  aEqüino  aAnimal conservation  aCavalo pantaneiro  aConservacao animal  aEquine  aMarca molecular  aMicrosatellites  aMolecular marks1 aSERENO, J.
