This study aimed to characterize and compare the aspects involved in the microstructural formation of the Holstein and Gir breed hoof wall by histomorphometry, three-dimensional microtomography and microhardness test techniques. Seventy-two (18H/18G thoracic and 18H/18G pelvic) Holstein (H) and Gir (G) breed hooves were collected in slaughterhouses. The hooves were divided into six groups according to breed and age group: 24 to 36 months (C1H/C1G), 36 to 60 months (C2H/C2G) and over 60 months (C3H/C3G). The normality and homogeneity analysis of morphometric variables by the Kolmogrov-Sminov and Bartlett tests was conducted as a statistical model. Once the assumptions were met, the Sigmastat 3.5 software was used and the means were compared by T test. The...
