Effect of grape pomace from red cultivar 'Nero d’Avola' on the microbiological, physicochemical, phenolic profile and sensory aspects of ovine Vasted…
2022
Abstract Aims The purpose of this study was to functionalize an ovine stretched cheese belonging to 'Vastedda' typology with red grape pomace powder (GPP) of Nero d’Avola cultivar and to characterize the microbiological, physicochemical, phenolic profile and sensory characteristics of the final cheeses. Methods and Results Before cheeses production, GPP was characterized for its microbiological profile, antibacterial activity and polyphenolic content. No colonies of bacteria and yeasts were detected in the GPP. GPP showed a large inhibition spectrum against spoilage and pathogenic bacteria. Three classes of polyphenolic compounds belonging to flavan-3-ols, flavonol and phenolic acids were i…
SOIL FERTILITY, GREENHOUSE GAS EMISSIONS AND AGRONOMIC PERFORMANCE IN A VINEYARD WITH DIFFERENT SOIL MANAGEMENT IN A SEMIARID MEDITERRANEAN ENVIRONME…
2017
In the semiarid Mediterranean environment, vineyard soils are often characterised by intensive tillage and large supply of inorganic fertilizers. Those practices, coupled with the semiarid Mediterranean climate features (warm to hot, dry summers and mild, wet winters),speed up the mineralisation of soil organic matter (SOM) so that many lands have lost much fertility. To counteract SOM decline, the introduction of cover crops with or without nitrogen (N) fixing forage legumes, has become a management technique widely used. Indeed, cover crops besides increasing SOM and potentially mineralisable N, it can mitigate soil erosion in sloping vineyards. However, the competition risk for soil wate…
Modeling soil organic carbon stock after 10 years of cover crops in Mediterranean vineyards: improving ANN prediction by digital terrain analysis.
2018
Estimate changes in soil organic carbon (SOC) stock after Agro Environment Measures adoption are strategically for national and regional scale. Uncertainty in estimates also represents a very important parameter in terms of evaluation of the exact costs and agro environment payments to farmers. In this study we modeled the variation of SOC stock after 10-year cover crop adoption in a vine growing area of South-Eastern Sicily. A paired-site approach was chosen to study the difference in SOC stocks. A total 100 paired sites (i.e. two adjacent plots) were chosen and three soil samples (Ap soil horizons, circa 0-30 cm depth) were collected in each plot to obtain a mean value of organic carbon c…
L'incremento della sostenibilità ambientale attraverso una corretta gestione dell'irrigazione.
2014
Lo scopo di questo lavoro è quello di mettere a punto, a partire dalle informazioni territoriali quali caratteristichemeteorologiche e pedologiche, uno studio capace di valutare la sostenibilità della gestione irrigua in tre ipotetiche parcelle sperimentali individuate nel territorio del sottobacino Iudeo-Bucari (TP). Sitratta di tre vigneti che rappresentano per caratteristiche morfologiche e gestionali l'intero sottobacino, ovvero una delle aree maggiormente vitate della Sicilia. Il fine è valutare la sostenibilità della gestione irrigua in termini di risparmio energetico, attraverso l'applicazione del modello di bilancio idrico FAO 56. Questo tipo di studio pone le basi per la redazione …
Genetic diversity of Mediterranean cattle breeds related to geography and climate
2015
In recent decades, changes in climate have caused impacts on natural and human systems. Mediterranean countries will be particularly affected by this phenomenon, with growing temperatures and reduced rainfall. Understanding how species and ecosystems respond to climate change has become a crucial focus in biodiversity conservation and management. The genome-wide SNP panels allows providing background information on genome structure in domestic animals, opening new perspectives to livestock genetics. The International Project GALIMED "Genetic Adaptation of Bovine Livestock and production systems in MEDiterranean region", develops an integrated approach that combines the analysis of SNP marke…
LINKAGE DISEQUILIBRIUM AND GENETIC DIVERSITY IN TWO SICILIAN CATTLE BREEDS ASSESSED BY BOVINE SNP CHIP
2013
The Modicana (MOD) and Cinisara (CIN) are two Sicilian cattle breeds farmed in extensive systems and their economic importance lies on the traditional making of two typical ‘pasta filata’ cheeses. The aim of this study was to explore the genetic structure and the extent of Linkage Disequilibrium (LD) of MOD and CIN cattle breeds. A total of 144 animals were genotyped, using the Bovine SNP50K v2 BeadChip. The squared correlation coefficient between two loci (r2) was used as a measure of LD. Principal components analysis (PCA), molecular inbreeding (F) and Bayesian clustering algorithm (Pritchard et al., 2000) were used to explore the relationship between individuals and populations. The r2 r…
Genome-wide scan for Runs of Homozygosity in Valle del Belice sheep
2017
The current availability of very large numbers of single nucleotide polymorphisms (SNPs) throughout the genome makes these markers particularly suitable for the detection of genomic regions where a reduction in heterozygosity occurred and offers new opportunities to improve the accuracy of inbreeding (F) estimates. Runs of homozygosity (ROH) are contiguous lengths of homozygous segments of the genome where the two haplotypes inherited from the parents are identical. Here, we investigated the occurrence and the distribution of ROH in medium-density SNP genotypes (~ 50 000) in order to characterize autozygosity in 512 individuals of Valle del Belice sheep and identify the regions of the genom…
Application of molecular markers to investigate genetic diversity in Sicilian livestock
2014
La diversità genetica delle specie e razze di interesse zootecnico, rappresenta un’importante risorsa in tutti i sistemi di allevamento . Per lo studio della diversità genetica, nel corso dei decenni sono stati sviluppati diversi metodi che si basano su informazioni del pedigree o su dati molecolari (microsatelliti e SNPs, Single Nucleotide Polymorphisms). Con l’aumento della disponibilità di marcatori molecolari per la maggior parte delle specie di interesse zootecnico, e con lo sviluppo di sofisticate tecniche analitiche, sta crescendo la capacità di caratterizzare la variabilità genetica delle razze. Inoltre, ad oggi, poche sono le informazioni sulla diversità genetica delle razze e dell…
