Variance component estimation for SCS in different local breeds and species
2009
Chromosomal assignment of the ovine hairless (hr) gene by fluorescence in situ hybridization.
2008
Congenital hypotrichosis in mammalian species consists of partial or complete absence of a hair coat at birth. Affected individuals having a partial hair coat at birth may loose it subsequently.The aim of this paper was to physically map the ovine hr gene using fluorescence in situ hybridization (FISH).A preliminary study on an internet data bank (http://www.informatics.jax.org) showed that the regions of the hr gene on murine chromosome 14 and human chromosome 8 present homology with ovine chromosome 2.
β-lactoglobulin gene promoter: new SNPs in sheep and goat
2008
β-lactoglobulin (β-lg) is the major whey protein in milk of ruminants and several non ruminant species, but it is lacking in rodents, lagomorphs and human. The aim of this work was sequencing the promoter region of β-lg gene in Sicilian sheep and goat dairy breeds, in order to identify polymorphisms. In these species, the promoter region was aligned using the sequences available on database. A common set of primers was designed to amplify and sequence a fragment of approximately 2.1 kb. Within this region, 12 single nucleotide polymorphisms (SNPs) were identified in goat breeds: 7 out of them were not yet reported in literature. Moreover, in sheep breeds 15 SNPs were newly identified. Using…
How Geography and Climate Shaped the Genomic Diversity of Italian Local Cattle and Sheep Breeds
2022
International audience; Understanding the relationships among geography, climate, and genetics is increasingly important for animal farming and breeding. In this study, we examine these inter-relationships in the context of local cattle and sheep breeds distributed along the Italian territory. To this aim, we used redundancy analysis on genomic data from previous projects combined with geographical coordinates and corresponding climatic data. The effect of geographic factors (latitude and longitude) was more important in sheep (26.4%) than that in cattle (13.8%). Once geography had been partialled out of analysis, 10.1% of cattle genomic diversity and 13.3% of that of sheep could be ascribe…
Mi chiamo Serban e non sono il romeno di nessuno, sono il romeno di me stesso. Pratiche di assoggettamento e soggettivazione tra pastori sardi e serv…
2018
«I am Serban, a Romanian who does not belong to anybody, I belong to my- self». Subjugation and subjectification practices between Sardinian she- pherds and Romanian servant shepherds The article investigates the role of the Romanian paid worker in the Sardinian countryside that replaces the traditional figure of the local «servo pastore» (Sardinian servant shepherd). The focus is on the symbolic and relational ten- sion between Sardinian shepherds and Romanian salaried workers, starting from extensive ethnographic material based on participant observation and in-depth interviews. By analyzing their work practices and daily interactions as well as what the Sardinians said about the Romanian…
Genomic Tools for the Characterization of Local Animal Genetic Resources: Application in Mascaruna Goat
2022
Italy contains a large number of local goat populations, some of which do not have a recognized genetic structure. The “Mascaruna” is a goat population reared for milk production in Sicily. In this study, a total of 72 individuals were genotyped with the Illumina Goat_IGGC_65K_v2 BeadChip with the aim to characterize the genetic diversity, population structure and relatedness with another 31 Italian goat populations. The results displayed a moderate level of genetic variability for Mascaruna, in concordance with the estimated values for Italian goats. Runs of homozygosity islands are linked to genes involved in milk production, immune response and local adaptation. Population structure anal…
Lampedusa 2016: per un dialogo tra generazioni
2016
Primo feedback su un progetto di mediazione comunitaria in corso a Lampedusa, dedicato alle relazioni giovani adulti in un'isola duramente provata dall'esperienza degli sbarchi, ma ancora di più dalla massiccia presenza di operatori dell'accoglienza e della sicurezza, la cui presenza ha alterato l'equilibrio comunitario. L’idea guida del progetto suppone che sia possibile attivare percorsi di gestione condivisa delle tensioni esistenti tra le componenti della generazione degli educatori (genitori, insegnanti, catechisti, specialisti impegnati in progetti per gli adolescenti), attraverso cui attivare la loro collaborazione sull’obiettivo comune di ritessere le relazioni tra le generazioni su…
