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...

Abnormal, abusive, and stress-related behaviors in baboon mothers

BACKGROUND: Psychiatric disturbances during pregnancy and the postpartum period are especially serious, given the negative effects on the mother as well as the child. Understanding the causes of such disturbances has been difficult owing to the complexity of psychological, social,...

Conflict resolution following aggression in gregarious animals: a predictive framework

Knowledge of how animals manage their conflicts is critical for understanding the dynamics of social systems. During the last two decades research on gregarious animals, especially primates, has focused on the mechanisms of conflict management, mainly on friendly postconflict reunions...

Effectiveness of enrichment devices during brief periods of social restriction in singly housed baboons

Data were collected on the animals' (three singly caged adult males) daily biscuit intake and activity levels as well as log activity prior to, during, and following social restriction (housed in separate room in which no other animals are present),...

Onset of aggressive toy biting by a laboratory baboon coincides with cessation of self-injurious behavior

After age 7.1 years, SIB became more frequent, usually directed at one knee. Neither daily Prozac or periods of social contact [grooming-contact bars] eliminated SIB. The baboon abruptly ceased SIB at age 12.5 years, coinciding with the onset of aggressive...

Survey of NIH-Funded Investigators Who Use Nonhuman Primates

Current use of nonhuman primates: 58% Rhesus macaques, 10% Long-tailed macaque, 10% Baboons, 7% Pig-tailed macaques, 4% Squirrel monkeys, 3% Chimpanzees, < 2% Other species. Respondents' most common recommendation for meeting future nonhuman primate needs deal with increasing the availability...

Artificial weaning of Old World monkeys: Benefits and costs

The perceived benefits of permanent, pre-weaning mother-infant separation are not supported by scientific findings. ... As long as there is an excessive number of monkeys and insufficient cage space, there is no ethically legitimate reason for attempting to enhance the...

Reproduction in baboons: The influence of environmental enhancement

A number of factors may be influencing the improved reproductive performance of this baboon population. The new facility provides increased space, more complex climbing structures, and decreased competition for food than the old setting.

The effect of four enrichment conditions on abnormal behavior in seven singly caged baboons (Papio hamadryas anubis)

Seven singly caged juvenile baboons were selected for behavioral intervention due to the severity of their abnormal behavior. Continuous all occurrence sampling method determined durations of abnormal and common behaviors throughout the ten-week study. Analysis of baseline behavior (fifteen 30-minute...

Cortisol responses to immobilization with Telazol and ketamine in baboons (Papio cynocephalus/anubis) rhesus macaques (Macaca mulatta)

The injection and blood sampling process increased cortisol levels in monkeys not trained to extend an arm but exerted no effect on cortisol in trained macaques. Thus, the animals' physiological responses to blood sampling and immobilization are influenced by such...
