Phenotypical characterization of pantaneiro cattle in Brazil (Caracterización fenotípica del bovino pantaneiro en el Brasil)

Mazza M.C.M.

Description

Abstract
The spanish cattle breeds brought by settlers reaching the Pantanal later joined portuguese breeds and their descendants formed a local breed called Pantaneiro, Cuiabano or Tucura cattle. Through natural selection and evolutionary processes, these cattle adapted to the ecological conditions of the Pantanal (16o-22o S and 55o-58oW), a floodplain in the upper Paraguay river basin. Since the beginning of this century, these populations have been gradually substituted by Zebu cattle, placing this genetic resource in danger of extinction. The Pantanal Agricultural Research Center (CPAP-EMBRAPA) founded a conservation bank at its experimental station at the Pantanal (Nhumirim Ranch). Literature on the subject is very scarce
some publications from the beginning of the 20th century describe the Pantaneiro cattle as small sized with short red or brown hair with lighter coloration on the back
short and thin horns, upturned and pointed to the front
white ring around the snout and a lighter circle around the eyes. However, since the end of the 19th century, interbreeding, mainly with the Franqueiro cattle (descendant from portuguese breeds, formed in Minas Gerais, Brazil) and the Zebu has occurred.
Resumen
Las primeras razas bovinas, traídas al Pantanal por los colonizadores y más tarde las portuguesas y sus descendientes, formaron una raza local: bovino Pantanero, Tucura o Cuiabano. A través de la selección natural y de los procesos evolutivos estos bovinos se adaptaron a las condiciones climáticas e hidrológicas del Pantanal (16-22oS y 55-58oO) - región inundable del río Paraguay. Desde comienzo del siglo, la introducción de ganado Cebú, ha puesto a estos recursos genéticos en peligro de extinción. El Centro de Pesquisa Agropecuária do Pantanal (CPAP-EMBRAPA) fundó un banco de conservación en su estación experimental en el Pantanal (hacienda Nhumirim). La literatura sobre el asunto es muy escasa
a comienzos del siglo 20 describen al bovino Pantanero como: tamaño reducido, piel gruesa, pelo corto, de color castaño o rojo, con tendencia a clarear en el dorso, cuernos cortos y finos, volviendo para adelante y encima, anillo blanco alrededor del hocico y un círculo más claro en torno a los ojos. Desde el final del siglo 19 se ha cruzado con otras razas, principalmente ganado Franqueiro (descendiente de razas portuguesas, formado en Minas Gerais, Brasil) y Cebu. Las poblaciones actuales son muy semejantes a las descritas al inicio del siglo y aun con características de las razas originales españolas y portuguesas. También tiene cierta semejanza fenotípica con el criollo del Beni (Bolivia) y con el Casanare de Colombia.
