Removals based on low within-matriline relatedness can reduce severe aggression in captive rhesus macaques

Previous observational research of captive rhesus macaques suggests that higher coefficients of relatedness within matrilines are associated with lower rates of severe within‐matriline aggression and more cohesive grooming communities. We tested whether experimental removals targeted to increase the relatedness coefficient...

Behavioral and physiological outcomes in nursery-reared pigtailed macaques (Macaca nemestrina)

The Infant Primate Research Laboratory at the Washington National Primate Research Center incorporates a number of rearing techniques aimed at assuring the welfare and enhancing behavioral outcomes for infants reared in the nursery. We recently instituted full‐time peer group social...

Nursery rearing macaques – An overview from a veterinary perspective

A variety of clinical and research scenarios require nursery rearing of infant macaques. Nursery rearing practices vary across institutions and are conducted with a range of personnel and facility resources. Caretakers, veterinarians, research and behavioral staff work together to ensure...

Training non-lactating rhesus macaques to act as foster mothers

There can be psychological and physiological consequences resulting from nursery rearing rhesus macaques. To reduce the need for nursery rearing, orphaned infants are often placed with lactating foster mothers. Unfortunately, a supply of these lactating females is not readily available...

Effect of concrete slats, three mat types and out-wintering pads on performance and welfare of finishing beef steers

The objective was to investigate the effect of placing mats on concrete slatted floors on performance, behaviour, hoof condition, dirt scores, physiological and immunological variables of beef steers, and to compare responses with animals on out-wintering pads. Continental crossbred beef...

Personality, environmental stressors, and diarrhea in Rhesus macaques: An interactionist perspective

Previous research has repeatedly shown both personality and psychological stress to predict gastrointestinal disorders and chronic diarrhea in humans. The goal of the present research was to evaluate the role of personality, as well as psychological stressors (i.e., housing relocation...

Coping style and cortisol levels in infancy predict hair cortisol following new group formation in captive rhesus macaques (Macaca mulatta)

Social instability in primate groups has been used as a model to understand how social stress affects human populations. While it is well established that individual cercopithecines have different temperaments or personalities, little is known about how temperament mediates the...

Providing feeding enrichment by hand mitigates anxiety among laboratory-housed rhesus macaques (Macaca mulatta)

Some husbandry procedures may be perceived as aversive by cage‐housed rhesus macaques. We assessed whether providing feeding enrichment by hand as opposed to placing it on a caging surface decreases anxiety responses to daily husbandry activities. Eleven adult males and...

Management of weight and body condition for captive adult and aging chimpanzees (Pan troglodytes)

With the goal of finding a practical way to improve and/or maintain the body condition of overweight chimpanzees to promote health and welfare, several feeding protocols' effects on chimpanzee body condition scores (BCS) were evaluated. BCS were assessed at the...

Dams’ social behaviour and long-term cortisol profiles in response to their infants being nursery-reared

The influence of early rearing experiences on infants' social and neuroendocrine development is well characterized. However, little is known about the effects of nursery rearing (NR) on the infants' mothers. Such information is important in welfare considerations. In a two‐part...
