Estudio citogenético del ganado bovino Criollo Argentino biotipo Patagónico

Abstract

Se han analizado citogenéticamente 25 animales bovinos pertenecientes a la raza Criolla Argentina biotipo Patagónico, raza sobre la que no se ha actuado de forma selectiva sino que sólo ha actuado la selección natural por razones de aislamiento. Se ha observado en nuestro trabajo que no son portadores de alteraciones cromosómicas que puedan incidir sobre la fertilidad de los mismos, como la translocación robertsoniana 1/29, lo que explicaría la alta fertilidad que poseen en comparación con otras razas Criollas americanas en las que sí se han encontrado animales portadores de esta translocación y de otras alteraciones cromosómicas.

Twenty five animals belonging to the Argentinian Creole breed cattle Patagonic biotype, biotype originated only by the natural selection by the reasons of geographical isolation, were cytogenetically studied. The analized animals were not carrier of chromosomic alterations involved on the fertility, as the 1/29 robertsonian translocation. That would explain the high fertility observed in these animals in relation with other American Creole breeds in which was observed the presence of this translocation and others.
