Pairing successes with male cynomolgus macaques after vasectomy

Problem: Traumatism, self-traumatism and better environmental enrichment of singly housed Male Cynos in our colony of approximately 100 Cynos.We also encountered incidents of aggressive behavior towards caretakers and stereotypical behaviors such as overgrooming.Approach: In our primate environmental enrichment program, we...

What time is feeding? How delays and anticipation of feeding schedules affect stump-tailed macaque behavior

Results indicate that anticipation of feeding routines had a considerable negative impact on behavior. In the times when animals were awaiting to be fed, rates of self-directed behavior, inactivity, vocalization and abnormal behaviors all increased significantly. When feeding was delayed...

Early vs. natural weaning in captive baboons: The effect on timing of postpartum estrus and next conception

We examined the details of 73 recorded pregnancies of 45 adult females. ... The results of this study indicate that forced infant weaning did not improve reproductive productivity in our colony of baboons. In fact, the data indicate that most...

Behavioral enrichment for marmosets by a novel food dispenser

A mealworm dispenser was constructed and used to promote foraging activities in a group of 11 marmosets. The dispenser was not monopolized by a dominant individual for more than 10% of the total time.
