[Measurement of temperature generation in the corium of bovine claws during claw trimming with an angle grinder using different grinding and cutting disks].

On 80 bovine hindclaws from slaughtered cows a correct functional claw trimming (sole horn thickness 5 mm; group 1) and on further 80 hindclaws a standardised, incorrect claw trimming (sole horn thickness 2 mm; group 2) was performed using 4 different disks (one cutting, three grinding disks). Two thermocouples were inserted into the solar corium and the heat production on the corium was measured during claw trimming. During correct functional claw trimming with each of the 4 disks a temperature increase in the corium with a median of < or = 0.
