In this study, we genetically characterized the Uruguayan pig breed Pampa Rocha. Genetic variability was assessed by analyzing a panel of 25 microsatellite markers from a sample of 39 individuals. Pampa Rocha pigs showed high genetic variability with observed and expected heterozygosities of 0.583 and 0.603, respectively. The mean number of alleles was 5.72. Twenty-four markers were polymorphic, with 95.8% of them in Hardy Weinberg equilibrium. The level of endogamy was low (FIS = 0.0475). A factorial analysis of correspondence was used to assess the genetic differences between Pampa Rocha and other pig breeds; genetic distances were calculated, and a tree was designed to reflect the distance matrix. Individuals were also allocated into clusters. This analysis showed that the Pampa Rocha breed was separated from the other breeds along the first and second axes. The neighbour-joining tree generated by the genetic distances DA showed clustering of Pampa Rocha with the Meishan breed. The allocation of individuals to clusters showed a clear separation of Pampa Rocha pigs. These results provide insights into the genetic variability of Pampa Rocha pigs and indicate that this breed is a well-defined genetic entity.

Goats are located predominantly in the dry Spain specially in Andalusia, Castilla-La Mancha, the Canary Islands, Murcia and Extremadura. In this paper we have analyzed 867 samples of 18 Spanish goat populations from different parts of the Iberian Peninsula (Azpi-Gorri, Blanca de Rasquera, Blanca Andaluza, Blanca Celtibérica, Florida, Malagueña, Murciano-Granadina, Negra Serrana, Payoya and Retinta) and the Balearic (Ibicenca, Mallorquina and Formentera goat) and Canarian Archipelagos (Ajuí, Majorera, Palmera, Tenerife North and Tenerife South). Twenty-three microsatellites have been amplified and the withinbreed genetic variation has been calculated through the analysis of the mean number of alleles, heterozygosity and F IS The values of expected heterozygosity (He) per breed ranged from 0.524 to 0.721 in Palmera and Florida, respectively, while the observed heterozygosity (Ho) ranged between 0.515 and 0.705 in Palmera and Retinta, respectively. Goat genetic diversity in Spain is very high, with a mean number of alleles, expected and observed heterozigosities across the breeds of 7.04, 0.668 and 0.621, respectively.

La especie caprina se localiza predominantemente en la España seca con gran protagonismo de Andalucía, Castilla-La Mancha, Canarias, Murcia y Extremadura. En este trabajo se analizan 867 muestras de 18 poblaciones caprinas españolas provenientes de diferentes zonas de la Península Ibérica (Azpi-Gorri, Blanca de Rasquera, Blanca Andaluza, Blanca Celtibérica, Florida, Malagueña, Murciano-Granadina, Negra Serrana, Payoya y Retinta) y de los archipiélagos Balear (Ibicenca, Mallorquina y cabra de Formentera) y Canario (Ajuí, Majorera, Palmera, Tinerfeña del Norte y Tinerfeña del Sur). Se amplifican 23 microsatélites de ADN y se determina la variación genética de las razas mediante el análisis del número medio de alelos, la heterocigosis, y el estadístico F IS. Los valores de heterocigosis esperada (He) oscilan entre 0,524 en la raza Palmera y 0,721 en la Florida mientras que la heterocigosis observada (Ho) fluctúa entre 0,515 en la Palmera y 0,705 en la Retinta. En España existe una diversidad genética caprina elevada con valores de número medio de alelos, heterocigosis esperada y observada para todas las razas de 7,04, 0,668 y 0,621 respectivamente.

The wild boar, a cinegetic species of Iberian Peninsula, has numerous sub-populations ofSus scrofa mediterraneus. Doñana National Park is the most important biological reserves in Spain and the largest protected area with great ecological diversity, distributed on three basic types of ecosystems: sand dunes, beaches and marshes. Here live together a variety of species: mammals, birds, reptiles, fishes... and, among them, the wild boar. In order to determine the genetic diversity, also in comparison with other Spanish populations, we studied 25 microsatellite pigs markers and found genetic variation within and among populations by analysis of heterozygosity (0.53), number of alleles (5.60), deviation by HW equilibrium and Fis index (0.02).

El jabalí de interés cinegético en la península Ibérica, cuenta con numerosas sub-poblaciones de Sus scrofa mediterraneus. El Parque Nacional Doñana es la reserva biológica más importante de España y la mayor superficie protegida con gran diversidad ecológica distribuida en tres tipos básicos de ecosistemas: dunas, playas y marismas en los que cohabita gran variedad de mamíferos, aves, reptiles, peces.... entre los que se cuentan poblaciones de jabalí. Para conocer su diversidad genética, en comparación con otras poblaciones españolas, se han estudiado 25 marcadores microsatélites porcinos y se ha determinado la variación genética dentro y entre poblaciones mediante el análisis de la heterocigosis (0,53), número de alelos (5,60), desviación del equilibrio de HW y Fis (0,02).
