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.

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…
The quality of Valle del Belice sheep’s milk and cheese produced in the hot summer season in Sicily
2013
In response to the growing consumer demand for fresh cheese in summer, this investigation was aimed to evaluate the chemical and microbiological characteristics of sheep’s milk and cheese produced in Sicily in the hot summer months. A total of 810 bulk milk samples collected from 17 farms rearing ewes of the Valle del Belice breed were analysed for chemical composition, somatic cell count, total bacterial count and clotting parameters. Samples (n = 18) of Protected Designation of Origin Vastedda della valle del Belice cheese produced in six dairies were collected in summer, autumn and spring and analysed for chemical composition, microbiological profile and fatty acid (FA) composition.

Restauri in Sicilia: gli interventi sui beni architettonici danneggiati dal terremoto del 1968 nella Valle del Belice
2020
Questo contributo mira ad integrare lo scenario culturale delle eterogenee esperienze incluse nella sessione “Protezione, pratica, codici e norme” del secondo Convegno Internazionale della SIRA Società Italiana per il Restauro dell’Architettura. L’articolato ventaglio dei casi studio, che spazia dal tema della tutela dei siti d’interesse ambientale alle normative settoriali in Italia e Francia, ed include le questioni tecniche e metodologiche riguardanti il cantiere di restauro, è completato dall’esperienza del restauro dei beni architettonici nei centri urbani danneggiati dal terremoto che interessa la valle del Belice in Sicilia nel 1968. Dopo aver inquadrato i luoghi danneggiati dal viol…
Detection of genomic regions underlying milk production traits in Valle del Belice dairy sheep using regional heritability mapping
2021
The aim of this study was to identify genomic regions underlying milk production traits in the Valle del Belice dairy sheep using regional heritability mapping (RHM). Repeated measurements for milk yield (MY), fat percentage and yield (F% and FY) and protein percentage and yield (P% and PY), collected over a period of six years (2006-2012) on 481 Valle del Belice ewes, were used for the analysis. Animals were genotyped with the Illumina 50k SNP chip. Variance components, heritabilities, and repeatability within and across lactations were estimated, fitting parity, litter size, season of lambing, and fortnights in milk, as fixed; and additive genetic, permanent environment within and across …
Rigenerazioni: città e territori nelle ricostruzioni
2009
Si esplorano le ragioni della permanenza dell’insediamento umano nel territorio attraverso il confronto di tre casi: il Belice, l’alta Valle dell’Agri, Messina; tre territori che in diversi modi e in diverse epoche hanno affrontato eventi distruttivi e si sono misurati con processi di ricostruzione interrogandosi sul proprio futuro.
