Estimated marginal mean and standard error for skin temperature of piglets measured with an infra-red thermometer near the xiphoid process. Results are shown after the first restraining and administration of local anesthesia (LA) or sham injections (NO LA) (a, n = 162) and after the second restraining and castration with local anesthesia (LA) or sham injections (NO LA) (b, n = 176). The piglets were restrained with either a tubular bench (TUBE) or a castration rack (HANGING)
