ABSTRACT
Reduced welfare and productivity of dairy goats have often been associated with poor claw health, especially conditions such as claw overgrowth and deformations. It is known that periodic claw trimmings have prophylactic and therapeutic effects on these problems, and this study aimed to evaluate if the additional use of an angle grinder to finish trimming overgrown and deformed goat claws, after the usual trimming using hoof shears, could provide further changes in these claws. For this, twelve Saanen goats (57.29 ± 11.15 kg of body weight, 3.08 ± 1.78 years old) were selected by presence of severe claw overgrowth, and absence of claw alterations of other nature. Their claws were trimmed in two steps, first using hoof shears and then using an angle grinder. Morphometric, baropodometric, and conformational aspects of all claws were assessed before claw trimming and after each trimming step. To analyse the effects of the trimming steps in each claw, the Tukey's test was used on parametric data, with 5% probability, and descriptive statistics were used on non-parametric data. Although this is a small pilot study, results suggest that using an angle grinder after the use of hoof shears, could further reduce heel length and sole width of claws, as well as reduce the number of deformed claws. The incorporation of the second trimming tool, could also further increase the frequency with which the point of maximum pressure was found in the toes, rather then in the heels of the claws as seen in deformed claws.
