This breed was a result of the crossing of breeds from the Iberian peninsula, both Spanish and Portuguese, during the occupation of the Pantanal region. At the present time, there are few Pantaneiro cattle nuclei due to the random crossing with Nellore cattle from the beginning of the XX century. In spite of this, this ecotype is important material for genetic studies due to the natural selection in underwent for the specific ecosystem of the Pantanal. Comparative advantages can be observed for this breed when compared to other breeds or when used in cross breeding systems with "improved" breeds. As well as the historical importance in terms of occupation of the region, it is useful in environmental conservation since it doesn't require environmental modification for it's production and reproduction. This is especially important in the Pantanal region with the dynamics of flooding and dry periods.  aBrazil  aPantanal  aGenética  aBovino pantaneiro  aBrasil  aGenetic  aPantaneiro cattle1 aABREU, U.
