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.
Impiego di granelle di leguminose in alternativa alla soia nella produzione di carne ovina biologica

Use of legume grains in substitution of soybean meal in organic lamb meat production. This study aimed to evaluate the effects of replacing soybean meal in the diet with alternative legume grains without GMO presence and at low aflatoxin risk, on the growth and carcass and meat quality traits of lambs. After weaning at 66±6 d of age, 28 male Comisana lambs were divided into 4 groups and gradually adapted to diets over a 15-d period. Until slaughter at 129±6 d of age, each group received ad libitum pelleted alfalfa hay and concentrates differing for the protein source: chickpeas (CP), faba beans (FB), peas (PE) and soybean meal (SM). Lambs growth and carcasses weight were not modified by the…

Genome-wide analysis of Italian sheep diversity reveals a strong geographic pattern and cryptic relationships between breeds
2014
Summary Italy counts several sheep breeds, arisen over centuries as a consequence of ancient and recent genetic and demographic events. To finely reconstruct genetic structure and relationships between Italian sheep, 496 subjects from 19 breeds were typed at 50K single nucleotide polymorphism loci. A subset of foreign breeds from the Sheep HapMap dataset was also included in the analyses. Genetic distances (as visualized either in a network or in a multidimensional scaling analysis of identical by state distances) closely reflected geographic proximity between breeds, with a clear north–south gradient, likely because of high levels of past gene flow and admixture all along the peninsula. Sa…
Cellule somatiche in latte ovino: analisi e applicazione delle curve ROC
2013
Negli ovini da latte le mastiti costituiscono una delle principali cause di perdite economiche per la ridotta produzione e soprattutto per la scarsa qualità tecnologica del latte. Diversi studi hanno dimostrato che il contenuto in cellule somatiche (SCC) del latte può essere impiegato sia come metodo diagnostico sia come criterio di selezione nei programmi di miglioramento genetico per la resistenza alle mastiti. Obiettivo di questo lavoro è stato applicare la metodologia delle Receiver Operating Characteristics curves (ROC) per valutare la capacità diagnostica del SCC nel discriminare le mammelle infette da quelle sane e per individuare un valore soglia discriminante in ovini da latte. In …
