Summary

Pedigree and population viability analyses of a conservation herd of Moura breed from Embrapa Swine and Poultry were carried out. ENDOG software was used for pedigree analysis and VORTEX for population viability analysis. The data were obtained with the curator of the herd and a total of 411 animals born between the years of 1999 and 2011 for the analysis with ENDOG. The input data in VORTEX were obtained from a questionnaire answered by the curator of the herd. The Inbreeding Coefficient (F) was 0.06 percent, the average effective population size (Ne) was 30 animals with an average generation interval of 3.48 years. The extinction probability was 0 percent for a simulation period of 100 years and 3 percent for a period of 500 years. The determinant parameters for the viability of this herd were the entry of animals and prolificacy of the breed. Although the study did not indicate immediate risk of extinction of this herd, it should be constantly monitored with controlled population parameters to prevent the extinction of this last herd of Moura pig breed.

Résumé

Les analyses de la viabilité de la population et pedigree ont été effectuées sur un harde de la race Moura de l'Embrapa Porcins et Oiseaux. ENDOG logiciel a été utilisé pour l'analyse de pedigree et VORTEX pour l'analyse de la viabilité de la population. Les données ont été obtenues avec le conservateur du harde et un total de 411 animaux nés entre les années 1999 et 2011 ont été analysés avec ENDOG. Les données d'entrée dans VORTEX ont été obtenus a partir d'un questionnaire auquel ont répondu par le conservateur du harde. Le coefficient de consanguinité (F) était 0,06%, la taille effective de la population moyenne (Ne) était 30 animaux, avec un intervalle de 3,48 ans en moyenne de la production. La probabilité d'extinction était de 0% pour une période de simulation de 100 ans, et 3% pour une période de 500 ans. Les paramètres déterminant pour la viabilité de ce harde a été l'introduction des animaux et la prolificité de la race. Bien que l'étude ne mentionne pas le immédiat extinction, la dernière race de porcs Moura doit être contrôlée en permanence avec les paramètres de population pour éviter l'extinction.

Resumen

Se realizó el análisis de pedigrí y de viabilidad de la población de un rebaño de la raza Moura Embrapa Suínos y Aves. Se utilizó el Software ENDOG para el análisis de pedigree y VORTEX para el análisis de viabilidad de la población. Los datos se obtuvieron con el curador de lo rebaño y un total de 411 animales nacidos entre los años 1999 y 2011 se analizaron con ENDOG. Los datos de entrada en VORTEX se obtuvieron de un cuestionario contestado por el curador de lo rebaño. El coeficiente de endogamia (F) fue de 0.06%, el tamaño medio efectivo de la población (Ne) fue de 30 animales, con un intervalo medio de generación de 3,48 años. La probabilidad de extinción fue de 0% para un período de simulación de 100 años y 3% durante un período de 500 años. Los parámetros más importantes para la determinación de la viabilidad de este rebaño fuerón el ingreso de animales y prolificidad de la raza. Aunque el estudio no indica peligro inmediato de extinción, el último rebaño de la raza Moura debe ser monitoreado constantemente con los parámetros de población para evitar la extinción.
