<b>A note on the effects of classical music as environmental enrichment for white-lipped peccaries (</b><b><i>Tayassu pecari</i></b><b>)</b>

Several authors have proposed that using music as a sensory stimulation can positively impact animal welfare. We aimed to investigate the impact of classical music (classical music-300/Beethoven and Mozart) as environmental enrichment on the behavior of 25 white-lipped peccaries (Tayassu pecari) using an ABA design (A1/A2: control; B: enrichment). Over 63 hours of focal animal observation (5 minutes/individual) during five-day phases, we recorded affiliative, agonistic, inactive, and exploratory behaviors. Our results indicate that classical music significantly increased exploratory behaviors (P&lt;0.05) and decreased inactivity (P&lt;0.05) in peccaries, suggesting a positive welfare effect. While affiliative behavior showed no significant change, we observed a potential link between increased agonistic events and elevated exploratory behavior. These findings contribute to the ongoing debate regarding music as enrichment and highlight the need for further comprehensive research into the effects of auditory stimuli on this species.
