Modulus of elasticity and dry-matter content in flat and contracted claws}, abstract = {The modulus of elasticity (E) and dry matter content (DMC) of horn samples from two types of claw deformity (contracted and flat claws) were determined according to EN-ISO 527 and ASTM D 638-03. The overall E values for all segments combined were 168 ± 154 MPa (mean ± SD, n = 79) and 248 ± 196 (n = 90) for contracted and flat claws, respectively. These values were approximately 60 % and 40 % less than the E value of sound claw material. The high correlation between E and DMC, as previously found for sound claw horn material was not present in horn obtained from these types of pathologically altered claws.}, year = {2008}, journal = {Berliner und Münchener Tierärztliche Wochenschrift}, volume = {121}, pages = {95-101}, month = {03/2008}, publisher = {Schlütersche Verlagsgesellschaft mbH & Co.
