Genetic polymorphism at the CSN1S1 gene in Girgentana dairy goat breed
2013
The aim of this work was to evaluate the variability of the αs1-casein locus in the endangered Girgentana dairy goat breed in order to define genetic improvement and a conservation program for this breed. The study was performed on 200 dairy goats by means of different PCR protocols. The most frequent alleles were A (0.590) and F (0.290) followed by B (0.065) and N (0.047). CSN1S1 E allele was identified with a very low frequency (0.008). The most common genotype was AF (0.365) followed by AA (0.340). The high frequency of the strong genotypes is associated with the production of milk with high fat and protein content and with optimal technological properties. In Girgentana goat breed, the …
Fatty Acids as Biomarkers of the Production Season of Caciocavallo Palermitano Cheese
2021
Simple Summary In the Mediterranean environment, climatic variability determines a discontinuity in the forage availability of pastures. Caciocavallo Palermitano is a cheese obtained from the milk of the Cinisara cattle breed, mainly raised on pasture. The present study investigated the fatty acid profile of cheeses produced in two typical farms in the four seasons of the year, with the aim of identifying specific fatty acids that can be used as biomarkers to discriminate the productions obtained in the different seasons, in order to economically enhance those seasonal productions that have better health characteristics. The results revealed the possibility of distinguishing spring producti…
Genetic and environmental sources of variation for milk yield traits in Barbaresca siciliana breed
2001
Abstract Multi-trait animal model procedures were used to calculate variance for milk yield traits in the Barbaresca siciliana breed. The recorded data consisted of 14 791 lactations from 6678 ewes distributed among 44 herds from six provinces in Italy. The data-set with pedigree information used for the estimation of genetic parameters and correlation, included 6678 ewes with records, 757 dams, 4 paternal grandams, 28 maternal grandam and 2 maternal great-grandams, all without records, and additionally 301 sires, 3 paternal grandsires, 11 maternal grandsires and 1 maternal great-grandsires. The variables considered in the present study were the milk yield at 100 days (MY-100), 120 days (MY…
Ecological, morphological and genetic characterization of sympatric Haemonchus spp. parasites of domestic ruminants in Mauritania
1995
SUMMARYThe 4 species of ruminants (dromedary, zebu cattle, sheep and goat) in arid areas of Mauritania harboured Haemonchus spp. as the most frequent internal parasite. This was a rare situation where the 3 putative species, H. longistipes (dromedary), H. placet (zebu cattle) and H. contortus (sheep and goat) occurred sympatrically. The study was undertaken on hosts slaughtered at the Nouakchott abattoir, on the basis of monthly collection of worms. The environment was very unfavourable to H. placei and unfavourable to H. contortus, as intensity of infection remained low throughout the year, whereas infection in the dromedary was 10 to 20-fold higher. The survival strategies during the long…
Time-to-event analysis of mastitis at first-lactation in Valle del Belice ewes
2007
A time-to-event study for mastitis at first-lactation in Valle del Belice ewes was conducted, using survival analysis with an animal model. The goals were to evaluate the effect of lambing season and level of milk production on the time from lambing to the day when a ewe experienced a test-day with a recorded SCC greater than or equal to 750,000 cells/ml, and to estimate, for this trait, its heritability and the percentage of variation explained by the flock-year of lambing effect. A dataset with 2468 first-lactation records, collected from 1998 to 2003 in Valle del Belice ewes allocated in 17 flocks, was used. The Cox model used included lambing season and total milk yield adjusted for lac…
A Viable System View of the Japanese Lean Production System
2011
We highlight the main characteristics of lean production and we analyze them using a viable-systemic perspective. Doing so we consider the lean production with its osmotic interactions with the Japanese business system and we create a framework which highlights the key relations which are essential for the viability of the system.
EFFECT OF DIFFERENT ROOTSTOCKS ON VEGETATIVE GROWTH OF JAPANESE AND EUROPEAN PLUM CULTIVARS IN SOUTHERN ITALY: PRELIMINARY RESULTS
2007
The preliminary results of a new rootstock trial for Japanese and European plum cultivars are reported. Two clonal Prunus cerasifera ('Myrobalan 29C' and 'MrS 2/5'), two Prunus domestica ('Penta' and 'Tetra') and the peach × almond 'GF 677' were tested in a warm and dry climate of Southern Italy where the plum industry is recently increasing, particularly for the Japanese type. 'GF 677' showed the most vigorous habit together with a higher production at the first bearing year in comparison with 'Myrobalan 29C', while the two P. domestica types resulted in very low vigour. This result was more evident and statistically significant with the Japanese plum cultivar, whereas very low differences…
What to show on the wine labels: a hedonic analysis of price drivers of Sicilian wines
2013
Unlike previous literature, we construct a hedonic model of wine price that incorporates all the main categories of variables simultaneously to enable a better evaluation of their importance on wine price formation. A comprehensive model has the advantage of providing more reliable estimates of the attributes' implicit prices thereby facilitating firms' pricing and improving effectiveness of wine production and marketing decisions. We utilize two different datasets of Sicilian wines collecting data from influential wine guides. Our results suggest that wine price strongly depends on objective features such as vintage, alcoholic content, geographical origin, grape variety, producer size and …
Can Applications Designed to Evaluate Visual Function Be Used in Different iPads?
2018
SIGNIFICANCE: Apple devices could be suitable for vision tests, provided that the test has been correctly adapted to the device, after considering the spatial and colorimetric characterization of the screen. PURPOSE: The majority of vision applications has not been developed by vision or colorimetry experts and suffers from conceptual and design errors that may lead average users to an erroneous assessment of their visual capabilities. The reliability of vision tests depends on the accurate generation of the necessary visual stimuli in a particular device. Our aim was to ascertain whether a given color test, designed for a colorimetrically characterized device, might be used in another simi…
