No full textConsumer acceptance of Italian or New Zealander lamb meat: An Italian case study
No full textA Central location test was performed to compare heavy Apennine lamb meat to New Zealander lamb meat in order to create a Protected Geographical Indication for lamb meat. Roasted New-Zealander and heavy Apennine lamb legs were tested by 106 consumers according to the following experimental plan: blind phase (B) without any possibility to recognize the meat type tasted, expected phase (E) in which were described the characteristics of the two types of meat without tasting, informed phase (I) in which the tasted meat was recognized in provenience. Results showed in a nine point scale of appreciation for flavour, juiciness and overall pleasure, the highest values in Apennine lamb meat. B test showed the highest value for overall pleasure (P<0.01). Interaction, Italian lamb x Informed test showed the highest values for all the parameters except for overall liking for which Italian lamb x E test showed the highest values. About foreign lamb meat B test showed higher values than I and E test. Information about lamb meat origin showed disconfirmation for tenderness in Italian lamb meat. Foreign lamb meat showed a positive disconfirmation for flavour and overall pleasure, that confirm the better perception by consumers in blind consumption than in the informed one

No full textL'evoluzione della pratica dello stamping-out nella lotta alle epidemie.
No full textLa pratica dello stamping-out consiste nell’abbattimento obbligatorio degli animali (malati, infetti, sospetti infetti e, in alcuni casi, sospetti di contaminazione) e nella distruzione delle carcasse. Tale metodo, così come proposto dal Lancisi agli inizi del ’700, è stato per lungo tempo applicato nel controllo dei focolai di peste bovina, malattia presente in Europa sino alla fine della Grande Guerra e dal devastante impatto economico e sociale. In seguito, lo stamping-out è stato previsto dalla legislazione sanitaria di numerosi Paesi, per il controllo di malattie, alcune esotiche, in grado di causare ingenti perdite economiche e di diffondersi rapidamente da un paese all’altro. Con questo metodo sono state eliminate dal territorio italiano malattie quali l’afta epizootica, la peste suina classica e la peste suina africana. In epoche recenti, a livello internazionale, esso è stato applicato, ad esempio, nel controllo dei focolai di influenza aviare nel Sud-Est asiatico (anche in Italia), di BSE e di peste suina classica in Europa, di afta epizootica nel Regno Unito e in Sud-America. Il contesto che ha maggiormente contribuito al dibattito sullo stamping-out è quello che si è realizzato nel Regno Unito nel 2001, relativamente al controllo dei focolai di afta epizootica
Genomic insights into shank and eggshell color in Italian local chickens
Full text linkEggshell and shank color in poultry is an intriguing topic of research due to the roles in selection, breed recognition, and environmental adaptation. This study delves into the genomics foundations of shank and eggshell pigmentation in Italian local chickens through genome-wide association studies analysis to uncover the mechanisms governing these phenotypes. To this purpose, 483 animals from 20 local breeds (n = 466) and 2 commercial lines (n = 17) were considered and evaluated for shank and eggshell color. All animals were genotyped using the Affymetrix Axiom 600 K Chicken Genotyping Array. As regards shank color, the most interesting locus was detected on chromosome Z, close to the TYRP1 gene, known to play a key role in avian pigmentation. Additionally, several novel loci and genes associated with shank pigmentation, skin pigmentation, UV protection, and melanocyte regulation were identified (e.g., MTAP, CDKN2A, CDKN2B). In eggshell, fewer significant loci were identified, including SLC7A11 and MITF on chromosomes 4 and 12, respectively, associated with melanocyte processes and pigment synthesis. This comprehensive study shed light on the genetic architecture underlying shank and eggshell color in Italian native chicken breeds, contributing to a better understanding of this phenomenon which plays a role in breed identification and conservation, and has ecological and economic implications
