In this study 12 microsatellite markers are used to characterize the Caballo Monchino horse breed and to known the genetic relationships with other Spanish local horse breeds. The genetic diversity, allelic frequencies, heterozygosity, Wright's F statistics (FIS and FST) was calculated, and to establish the genetics relationship between Mediterranean horse populations a correspondence analysis was carried out.

The pedigree file of the Tudanca local bovine breed recovers information of animals born from 1966 to 2010 in 455 herds. The pedigree completeness level is characterised by a low number of equivalent complete generations (~2). Individual inbreeding and relatedness coefficients, and effective number of founders, ancestors and founder genomes, were computed. Average effective population size was estimated based on the regression of the inbreeding on genealogical amount of information, and effective population seize for the last generation were also calculated. Using this information, medium-term inbreeding rate evolution (50 years) was predicted. A high percentage of animals (87%) with a high level of inbreeding (>6,25) was found. The effective number of founder genomes (72) and the effective number of ancestors (88) reflect the genetic base of the current population, while the medium-term loss of genetic variability predicted from the effective population size (18-29) showed a breed under a low to moderate level of genetic risk.

The Pasiega cattle breed has been recently listed as endangered by the MARM (i.e. Spanish Ministry of Environment, Agriculture and Fisheries). The main objective of this study was to identify the potential difficulties in developing the Pasiega conservation strategy. To get information of the structure of the Pasiega farms, we performed co to the cattle raisers. The results showed that 86.7% were family farms. Forty-seven percent of farmers surveyed derived all their income from farming and 93.3% indicated that they earned the majority (i.e. 50% or more) of their income from agriculture. Seventy-three percent of farmers surveyed were older than 50 years, with 33.3% having a farm successor. Forty-two percent of farmers had got Pasiega cattle for more than 50 years and 26.7% were members of a health defence association. The population of Pasiega cattle is scarce accounting for 359 animals (i.e. mean= 5.6 head per farmer). Eighty-seven percent of farmers had other breeds and other species. The average size of farms was 40,5 ha, being slightly higher in San Pedro del Romeral (i.e. 54.3 ha/farm). Fifteen percent of the surface belonged to farmers with 37.8% being public grassland, this percentage was slightly higher in San Pedro Romeral (i.e. 57.4%). Our results showed that the Pasiega is a rustic breed which has been traditionally managed for decades. These cattle are able to range in very steep and rough terrain to forage the natural resources of the place. Usually the Pasiega farmers earn their income by selling the animals and no by dairy production. Feeding depends on grazing in summer and hay provisioning in winter, combining both systems in spring and autumn. The Pasiega cattle graze in large areas, with stone huts distributed in a lot of plots, and many of them are communal mountain grass. Source

We used molecular information from 27 polymorphisms located in 21 genes associated with economic traits as are milk production and its composition, growth, marbling, sensorial traits as are tenderness, juiciness, and coat colour useful for traceability, in order to evaluate production characteristics of the Pasiega breed. We found the presence of alleles B and E at the CSN3 locus which denote a good cheese ability; the predominance of allele T at the RORC locus associated with marbling and the possibility of selecting favourable genotypes at genes as CAST and VIM (for tenderness), PPARG (type of fatty acid), AANAT, PGAM2 or ME3 (underlying sensorial traits) as a way to improve meat quality.

Two sheep populations present in the Cantabria region in the North of Spain and named Guriezo and Blanca de la Peña were genetically characterised, also their origin and relationships with other geographically or culturally connected breeds were studied. A total of 457 individuals belonging to the two groups and to other such as Lacha, Bardhoka, Anogeiano, Gentile di Puglia, Laticauda, Churra Bragancana, Colmenareña, Manchega, Merina, Rubia del Molar and Segureña breeds were genotyped for 21 microsatellite markers. The results allow detecting the influence of the Lacha breed on the Guriezo population, but also the genetic differences of both sheep populations (Guriezo and Blanca de la Peña) from all others ovine breeds studied.
