Evaluation of some trace element levels in serum and claw tissue in cattle with different claw lesion

The aim of this study was to compare levels of serum and claw tissue chromium (Cr), manganese (Mn), iron (Fe), cobalt (Co) copper (Cu), zinc (Zn) and selenium (Se) in healthy cattle with various claw lesions and to evaluate the relationship between claw lesion and trace element levels. The animals were divided into two groups as healthy cattle and cattle with claw lesions. A total of 40 cattle were used as 10 healthy cattle and 30 cattle with claw lesions in the study. Hoof conformation measurements and hoof hardness values were determined in both healthy cattle and cattle with claw lesions. Blood and claw tissue samples (hoof wall and solar hoof) were taken to determine serum and claw tissue trace element levels in both groups. Cr, Mn, Fe, Co, Cu, Zn and Se levels were analysed in serum and claw tissue samples. Sole ulcer in 14 cattle (46%), white line disease in 2 cattle (7%), heel erosion (40%) in 12 cattle and both sole ulcer and heel erosion were determined in 2 cattle of the cattle with claw lesions. It was determined that the hardness value of the solar in the cattle with hoof lesions was higher than the healthy cattle. Cr, Mn, Fe, Co and Se levels in paries ungulae were found to be higher in the cattle with claw lesions, compared to the healthy cattle, while the Cu level of paries ungulae was statistically significantly higher in the healthy cattle compared to the cattle with claw lesions. In healthy cattle;, Cr, Zn and Cu levels in sola ungulae hoof tissue were higher than the cattle with claw lesions, while the Mn, Fe, Co and Se concentrations were lower than in those cattle with claw lesions. As a result, it was observed that Cu and Zn levels of the solear hoof in cattle with claw lesions were lower than in the healthy cattle. It can be suggested that trace elements such as Mn, Zn, Cu ve Se are very important for hoof health, and low levels of Cu and Zn in the solar hoof can increases rate of claw lesions in cattle with claw lesions.
