Thermography as a non-invasive measure of stress and fear of humans in sheep

No data have been published on the use of infrared thermography (IRT) to evaluate sheep emotions. We assessed whether this technique can be used as a non-invasive measure of negative emotions. Two voluntary animal approach (VAA) tests were conducted (and...

Emotions and ethical decision-making in animal ethics committees

Ethical evaluation of projects involving animal testing is mandatory within the EU and other countries. However, the evaluation process has been subject to criticism, e.g., that the committees are not balanced or democratic enough and that the utilitarian weighting of...

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...

Comparing abnormal and fear-related behaviour under two nursery rearing conditions for infant rhesus macaques

Two nursery rearing strategies for infant rhesus macaques (Macaca mulatta) were compared to measure effects on abnormal and fear‐related behavior. Changes made from the standard nursery‐rearing procedures (SN) included earlier exposure to peers, frequent peer‐group play sessions, the use of...

Long term behavioral and clinical outcomes for nursery reared macaques

Nursery rearing (NR) as an experimental manipulation has informed our understanding of the basic bio‐behavioral mechanisms of development. Nursery rearing also occurs for clinical support of infants that fail to thrive or are rejected by their mothers. Early experimental studies...

Rhesus monkey (Macaca mulatta) groups with more non-natal adult males per adult female have lower rates of aggression-induced trauma and greater reproductive success

Limiting contact aggression and social stress is a principal animal welfare challenge in managing large groups of captive nonhuman primates. This challenge is especially pronounced in rhesus monkeys (macaca mulatta), a species characterized by a relatively high frequency of aggression...

A comparison of activity patterns of captive chimpanzees (Pan troglodytes) housed in primadomes™ or corrals

Primadomes™ and corrals, two types of housing options available to captive chimpanzees, differ in several physical features, including closed (primadomes™) or open (corrals) tops, mesh (primadomes™) or concrete (corrals) walls, and available space per animal (142 ft2/individual in primadomes™; 516...

Predictors of pair housing success vary in captive St
