Captive-born animals frequently lose their anti-predatory abilities due to the absence
of encounters with their predators, but these abilities can be regained through specific
training. Anti-predator training can, thus, enhance the success of reintroduction
programs with predator naive animals. In addition, a good memory is important to guarantee
the effects of the anti-predator training and increase survival rate after release
into the wild. In the present study, anti-predator training sessions were applied
to 11 captive-born collared peccaries (Pecari tajacu), followed by memory tests at
30, 60 and 90 days after the end of the training sessions. The collared peccaries
responded appropriately to training against predators, showing alert, escape and predator
avoidance behaviors after anti-predator training; however, the animals maintained
these acquired behaviors for only 30 days after the end of the anti-predator training.
After 60 days, peccaries responded to the predator in a 'relaxed' manner, exhibiting
no anti-predator behaviors. For the trained collared peccaries to be released into
the wild, reinforcement in the anti-predator training would be required at least 30
days prior to release.
