Cattle domestication from wild aurochsen was among the most important innovations during Neolithic agricultural revolution. The available genetic and archaeological evidence points to at least two major sites of in India Near East, where zebu taurine breeds would have emerged independently. Under this hypothesis, all present-day European be descended cattle domesticated East subsequently spread diffusion herding farming lifestyles. We present here previously undescribed contrast with view,...
Recently different studies have formalized the way in which it is possible to obtain coancestry coefficients from molecular information (Caballero and Toro 2002; Eding Meuwissen 2001) by applying Malecot’s (1948) definition of kinship marker genes, though referring identity-by-state instead identity-by-descent 2002). The between two individuals, i j, probability that randomly sampled alleles same locus individuals are identical state. Because its straightforward relationship with...

Abstract By using a conditional gene targeting approach exploiting the cre‐lox system, we show that postnatal inactivation of myostatin in striated muscle is sufficient to cause generalized muscular hypertrophy same magnitude as observed for constitutive knockout mice. This formally demonstrates production site functional and this member TGFβ family growth differentiation factors regulates mass not only during early embryogenesis but throughout development. It indicates antagonist could be...
Summary The aim of this work is to highlight the need monitoring small populations conserve their genetic variability by using a set parameters characterize both structure and management practices. As representative example we analyse pedigree information endangered Xalda sheep breed Asturias. herdbook included total 805 animals 62 herds. number founders was 329. Nowadays, there are 562 live 26 active in risk losing diversity because abusive use certain individuals as parents. effective...
Although many research papers have studied diversity and differentiation within livestock species, genetic relationships among neighboring populations remain poorly understood. Here we apply recent methodologies to analyze the polymorphism of 14 microsatellites in 238 unrelated individuals belonging six sheep breeds from Northern Spain ascertain their historical relative contributions existing between populations. Individual genotypes were analyzed assess existence an underlying structure....
Canine adenovirus type 1 (CAdV-1) is responsible for infectious canine hepatitis. The disease has been described in captive American black bear (Ursus americanus) and European brown arctos arctos), with just one recently reported case a cub of free-ranging horribilis) from Alaska. aim this work to summarize findings related presence associated mortality CAdV-1 21 Cantabrian bears arctos) submitted necropsy Asturias Castilla y León (northwestern Spain) 1998 2018. On the basis...
Quantitative real-time reverse transcription PCR (qRT-PCR) is a useful tool for assessing gene expression in different tissues, but the choice of adequate controls critical to normalise results, thereby avoiding differences and maximizing sensitivity accuracy. So far, many genes have been used as single reference gene, without having previously verified their value controls. This practice can lead incorrect conclusions recent evidence indicates need use geometric mean data from several...
Five cattle Y-specific microsatellites, totalling six loci, were selected from a set of 44 markers and genotyped on 608 Bos taurus males belonging to 45 populations Europe Africa. A total 38 haplotypes identified. Haplogroups (Y1 Y2) previously defined using single nucleotide polymorphisms did not share haplotypes. Nine the 27 Y2-haplotypes only present in African cattle. Network correspondence analyses showed that this African-specific subfamily clustered separately main Y2-subfamily Y1...
Multi-host pathogens emerging and re-emerging at the wildlife-domestic animal interface affect wildlife management conservation. This is case of canine distemper virus (CDV), a paramyxovirus closely related to human measles rinderpest cattle. With an area 10,603 km2 , Asturias region in Atlantic Spain hotspot carnivore diversity, which includes largest Eurasian brown bear (Ursus arctos arctos) population one wolf (Canis lupus) populations south-western Europe. In 2020-2021, we recorded...
Abstract Understanding mortality causes is important for the conservation of endangered species, especially in small and isolated populations inhabiting anthropized landscapes where both natural human-caused may hinder these species. We investigated 53 free-ranging brown bears ( Ursus arctos ) found dead between 1998 2023 Cantabrian Mountains (northwestern Spain), a highly human-modified region are currently recovering after being critically threatened last century. detected traumatic...
Abstract A novel and simple methodology is introduced that allows accurate highly sensitive detection of microRNAs (miRNAs), taking advantage an amplification strategy based on multicomponent nucleic acid enzymes (MNAzymes), combined with a fluorescence resonance energy transfer (FRET) phenomenon. For this purpose, fluorescent dye (FAM) has been selected as donor, while gold nanoparticles (AuNPs) are employed acceptors, located close to each other through hybridisation the substrate. The...
Despite a number of recent studies that have focused on the origin domestic horses, genetic relationships between major geographical clusters still remain poorly understood. In this study we analyzed 296 bp mtDNA fragment from HVI region 171 horses representing 11 native Iberian, Barb, and Exmoor breeds to assess maternal phylogeography Iberian horses. The haplogroup with CCG motif (nucleotide position 15,494 15,496) was most frequent in Barb (0.42 0.57, respectively), regardless geographic...
The aim of this paper was to estimate direct and maternal genetic parameters for calving ease (CE), birth weight (BrW), weaning (WW), interval (CI) assess the possibility including information in beef cattle improvement programs. Field data, a total 59,813 animals (1,390 sires 1,147 grand sires) from Asturiana de los Valles breed, were analyzed with multivariate linear model.

Abstract. A total of 10,147 female goats from Burkina Faso were scored for 7 body measures and 12 qualitative traits. Sampling included the three main environmental areas goat breeds Faso: Sahel area (Sahelian goat), Sudan-Sahel (Mossi goat) Sudan (Djallonké goat). Overall, Sahelian had highest values all analysed measures. Differences between little. The is mainly spotted (61.92 %) with horns type “Spanish Ibex” (84.05 %), frequent absence beard (75.33 wattles (70.92 poorly developed udder...
Although louping ill affects mainly sheep, a 2011 outbreak in northern Spain occurred among goats. Histopathologic lesions and molecular genetics identified new strain of virus, 94% identical to the from Britain. Surveillance is needed minimize risk domestic wildlife species humans.
