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

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
