Extract

Mechanical properties of the hoof horn such as hardness, elastic modulus, bending stiffness and fracture toughness were influenced by the moisture content of the hoof horn (Collins et al., 1998; Baillie et al.; 2000). The moisture content of the hoof horn has been found to be affected by the micro-architecture and biochemical composition of the horn and by external factors such as humidity, chemicals and microbiological factors (Budras and Mulling, 1998). The aim of the experiment was to determine the influence of the moisture content and of storage methods, such as refrigerating in plastic bags and freezing, over the punch resistance and elastic modulus of the bovine hoof horn. Storage methods were studied for the determination of an experimental protocol in further research.
