Costruzioni di ‘identità’. I cinquant’anni della comunità belicina
2019
Il territorio è un essere vivente di grande complessità: il risultato di processi sinergici di co-evoluzione tra gli insediamenti umani e l’ambiente. Rappresenta quindi il campo in cui i diversi attori possono sviluppare un senso di identità, di appartenenza e di riconoscimento con il proprio luogo: l’identità spaziale, che varia da luogo a luogo e nel tempo. Nel 1968 la Valle del Belice (Sicilia) è stata danneggiata da un violento terremoto che ha trasformato radicalmente la regione e le sue comunità. A cinquant’anni dall’evento, il presente scritto analizza questa parte del territorio secondo tre diverse narrazioni: - caratteristiche fisico-materiali; - una prospettiva locale come area di…
Loss in milk yield and related composition changes resulting from different levels of somatic cell count in Valle del Belice dairy sheep
2015
Mastitis is the most common and costly disease in the dairy industry and is responsible for several production effects. Mammary infections cause high somatic cell count (SCC) and severe damage to udder tissue and result in important losses of milk yield and quality, curd and cheese yields in dairy ewes. The aim of this study was to determine the effect of different levels of SCC on milk yield and composition in Valle del Belice dairy sheep. The original data set used for this study included 92,261 records of 6,763 ewes. Data were collected between 1994 and 2006 in 15 flocks. Test-day records of milk yield (MY), fat % (F%), protein % (P%), and SCC were collected following an A4 recording sch…
Polymorphisms of β-defensin genes in Valle del Belice dairy sheep
2011
The aim of this work was to study β-defensin 1 (SBD1) and β-defensin 2 (SBD2) genes in Valle del Belice dairy sheep in order to identify polymorphisms that can be utilized as markers of the analyzed genes, and search for the functional effects and roles of the identified polymorphisms (variation of the amino acid sequence of the protein and stability of mRNA molecule). The study was conducted on 300 randomly selected animals belonging to four flocks. A total of seven SNPs were identified, two in SBD1 and five in SBD2. The two SNPs identified in SBD2 coding region, at position 1659 and position 1667, were non-synonymous, leading to amino acid changes in the protein product. Nevertheless, the…
Determination of milk production losses and variations of fat and protein percentages according to different levels of somatic cell count in Valle de…
2018
The somatic cell count (SCC) of milk is widely used to monitor udder health and the milk quality and because of its positive genetic correlation with mastitis this trait was included in breeding schemes of dairy sheep. The aim of this study was to estimate the loss in milk yield (MY) and related composition resulting from different levels of somatic cell count in Valle del Belice dairy sheep. Data were collected between 2006 and 2016 in 15 flocks following an A4 recording scheme. Somatic cell count (SCC), fat and protein percentage (F% and P%) were determined using mid-infrared spectroscopy. To evaluate loss in test day MY, F% and P%, five different classes of SCC were arbitrarily defined: …
L'architettura di Francesco Venezia nella ricostruzione post-sismica del Belice
2014
Una breve descrizione dei progetti realizzati da Francesco Venezia nei luoghi della tragedia sismica del Belice Questo breve testo si pone l’obiettivo di restringere il campo d’analisi nella descrizione di alcune opere realizzate dall’architetto campano, probabilmente il più grande interprete dei temi legati alla ricostruzione intesa come metafora e memoria del paesaggio della tragedia. Grazie alle esperienze di progetto maturate nel Belice, Francesco Venezia ha affermato il proprio profilo professionale catturando l’attenzione della critica internazionale che da allora lo ha seguito costantemente nella sua importante carriera di progettista, arrivando a segnalare alcune opere siciliane nel…
Test-Day Model Heritabilities for somatic cvell score and production traits in primiparous Valle del Belice sheep
2006
A repeatability test-day animal model was used to investigate heritabilities of somatic cell score (SCS) and milk production traits in Valle del Belice sheep. The heritability estimate for SCS falls within the range reported in literature (0.14±0.03), while estimates for milk production and composition traits were below those obtained by others, 0.12±0.03, 0.09±0.02, 0.14±0.03, 0.14±0.03, and 0.12±0.03, respectively, for milk yield, fat %, fat yield, protein %, and protein yield. Flock-test-day had a substantial effect on milk production traits but not on SCS. These results provide the basic parameters required for discussion of selection strategies and objectives in Valle del Belice sheep.
Paesi abbandonati e il ritorno della vita con l'arte
2020
In Italia, nella seconda metà del Novecento, numerosi furono i centri urbani abbandonati, a causa, ad esempio, dell’emigrazione, dei dissesti idrogeologici e degli eventi sismici. In Sicilia, i paesi di Gibellina, Salaparuta, Poggioreale, nella provincia di Trapani e Montevago, nella provincia di Agrigento, dopo il terremoto, del gennaio 1968, che colpì la parte occidentale dell’Isola, furono abbandonati e, negli anni successivi, ricostruiti, anche in siti distanti. Certamente l’attenzione iniziale fu rivolta alla costruzione delle nuove città, mentre dopo i danni dovuti alle scosse sismiche i resti degli antichi paesi furono lasciati al loro lento ed inesorabile degrado. Più recentemente, …
Vastedda della valle del Belìce, una DOP che può dare molto

Analysis of microbiological variation in PDO Vastedda della valle del Belìce cheese during the storage period
2011
The PDO “Vastedda della valle del Belìce” is a Sicilian pasta filata sheep cheese, made from raw milk without starter addition. It is a small round cheese without rind, weighing about 500-700 g. It is cheese is marketed also out of Sicily to allow its marketing and to prolong its shelf-life. The aim of this work was to evaluate the variation of microbiological parameters during the shelf-life period. Then 162 Vastedda cheeses from 18 cheese-making processes in 7 farms have been analysed at different times of storage at 4°C (0, 15, 30, 45, 60, 75, 90, 105, 120 days). Coliforms and E. coli were detected into 7/18 cheese-making processes and their count decreased during the storage period. Ent…
Parentage verification of Valle del Belice dairy sheep using multiplex microsatellite panel
2013
Abstract The aim of this work was to develop and evaluate a PCR based microsatellite markers multiplex system for parentage verification of Sicilian Valle del Belice dairy sheep. A total of 85 samples of blood and hair were collected and genotyped for 24 microsatellite markers in multiplex electrophoresis runs. A total of 269 alleles were detected across the 24 loci investigated. The PIC considering all loci was equal to 0.736, showing that this microsatellite panel was very polymorphic and highly informative. A parentage test was performed on 64 families generated with multiple sires. Results indicated 20.3% and 29.7% misidentification rates for females and males, respectively. In 8 cases,…
