“…The Fst in these goat populations was similar to the Fst found in other studies with Spanish goats (Martínez et al, 2006). The cause of these low values of Fst could be the phylogenetic proximity of the studied populations.…”

“…Mean Fis (0.76) was lower than the Fis value obtained in other goat breeds around the world (Barker et al, 2001;Xiang-Long and Valentini, 2004;Cañón et al, 2006) and higher than those found by Martínez et al (2006). The Fis by population is lower than the values obtained by Cañón et al (2006) in the Spanish breeds, except for Malagueña breed.…”

The population structure of the Murciano-Granadina breed was determined using 25 microsatellites from 266 goats of seven populations. The results of the genetic differentiation analysis showed that it is possible to differentiate the Murciana and Granadina populations even though a low F ST value (0.0432) had been obtained. Individuals could be assigned to their populations with a success rate of more than 80%. Bayesian-based clustering analysis of allele frequencies and multivariate analysis revealed that Murciana and Granadina populations were grouped in different clusters since K=3. The results demonstrate that Murciana and Granadina are still two different genetic groups included into MurcianoGranadina denomination. There is the opportunity to the genetically manage these populations, under a single herd-book but adding the necessary modifications to respect the conservation of the genetic diversity based on the use of multibreed models of genetic evaluation.Keywords: dairy goat, microsatellites, genetic diversity, conservation Murciano-Granadina, usando- RESUMO Determinou-se a estrutura da raça

“…Aunque algunas de las razas incluidas en este trabajo han sido previamente caracterizadas genéticamente (Martínez et al, 2004;Acosta et al, 2005;Cañón et al, 2006;Martínez et al, 2006Martínez et al, -2007Delgado et al, 2009), es la primera vez que se presentan datos de la diversidad genética de otras razas como es el caso de la raza Ibicenca o la cabra de Formentera, entre otras. Este estudio es el más amplio en cuanto a caracterización genética de razas caprinas autóctonas españolas ya que se estudian 15 de las 22 razas reconocidas oficialmente más dos poblaciones asilvestradas.…”

“…Therefore, the udder of this breed does not need a high percentage of connective tissue to avoid udder damage. The three breeds were affected by the dispersive effect of the genetic drift (island effect) of five centuries, producing different type of goats, all of them specialised as dairy animals (Martı´nez et al 2006), living in a subtropical zone (Canary Islands) which have a high meteorological variation between islands.…”

Tissue percentages (secretory, connective, ductal and vascular tissues) and the number and size of the alveoli in the udders of three dairy goat breeds under two milking frequencies (once-vs. twice-daily milking) were studied. Nine dairy goats, three of each breed studied (Majorera, Tinerfen˜a and Palmera), were milked during 6 weeks beginning at the tenth week of lactation. The right udder half was milked twice daily, and the left udder half was milked once daily. Moreover, during the experimental period, morphological udder data, milk yield, milk fractioning and milk composition were recorded. The goats were sacrificed and two samples for each gland were taken for the histological study. The statistical analyses revealed that the histological parameters were not influenced by the milking frequency, and that the breed determines different percentage of tissue components. Correlations between morphological parameters of the udder and milk-yielding parameters were high and determined the greater importance of the globosity and the structure of the udder in the milk production. Furthermore, it was determined that the percentage of secretory tissue in the mammary parenchyma has no correlation with the milk yield parameters in different high-production dairy breeds. Histological parameters (secretory and connective tissues) only have an impact in the milk fractions.
