Abstract

This study monitored the vocal responses of piglets, as indicators of well-being, to evaluate the effect of various sounds played during 2 simulations of stressful farm procedures: (a) the 5 min the animals were held as if for castration and (b) the first 20 h after weaning. The sound treatments included pink noise, music, vocalizations made by other piglets during actual castrations or the first hours after weaning, and silence (control). The study presented pink noise and music both with and without a binaural beat in the delta-theta frequency range. In both the handling and weaning situations, none of the sound treatments reduced the piglets' call rate below that heard during the control. Piglets vocalized most during playback of pink noise and least during silence and playback of calls from other pigs. These results suggest that playing music or other sounds provides no improvement in conditions for piglets during handling and weaning.
