| Abstract Scope |
The main objective of this study was to evaluate the composition and structure of hooves from Brazilian cattle specimens, as well as the influence of water content on their structure. Water absorption, FTIR, XRD, and SEM techniques were used to preliminarily analyze hooves’ composition and structure. Results showed both proximal and distal regions of the hoof wall present a maximum water intake of ~22 wt.%, after 3 days of immersion in distilled water. FTIR spectra showed characteristic peaks of amides A, I, II, and III, which are all present in the structure of α-keratin. XRD spectra presented broad peaks (~9.6 Å; ~4.2 Å), which are associated with the pitch in the α-keratin helical structure, and an increase in d spacing was observed with the increase in water content (from ~4.2 to ~4.5 Å). SEM images revealed a hierarchical structure divided into zones with different tubule shapes and sizes. |
