Preliminary studies on hoof characteristics in Amiata donkey
Alessandro Giorgetti | Luisa Andrenelli | Roberto Tocci | Clara Sargentini
In this work the biometrical, physical and chemical characteristics of Amiata donkey hoof were studied. The Amiata donkey is a local endangered breed and derives from the homonym mountain in Tuscany. This donkey, which was once used as pack animal in farms and in mines, is now involved in trekking, onotherapy and milk production. The mean hoof biometrics and its standard deviation were calculated. The physical and chemical characteristics were also estimated, through ANOVA, considering the hoof region as fixed effect: wall, white line and sole for hardness, wall and sole for chemical characteristics. The small size and healthy hoof, was basically cylindrical (crown cir./Foot plantar circ. ratio=0.9) and it showed higher hardness in wall (H=126.5± 3.3), followed by sole (H=105.2±3.3), and white line (H=74.0±3.3). The wall has shown the lower moisture content (%=11.7±3.2) and the higher content in Al, Mn, Li, Ni, Pb, Se. The positive correlation between Al, Li, Pb and Hardness has shown the hoof high resistence to toxic elements. Very interesting has seemed the negative correlation between K <em>vs</em> Li and Pb, to indicate the tendency of K to remove potentially harmful elements.
