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...

A successful strategy for social housing adult male cynomolgus macaques in triads

At Charles River, we are committed to ensuring all animals have the highest level of care and welfare. For juvenile, subadult and adult female cynomolgus macaques (Macaca fascicularis), we have a near 100% success rate for social housing. Sexually mature...

The relationship between self-directed anxiety behaviors and cortisol in socially housed capuchin monkeys (Cebus [Sapajus] apella)

Non‐human primates are excellent models for the study of human social anxiety. Both humans and non‐human primates form complex relationships with others, and exhibit signs of distress when those relationships become unstable. Self‐directed behaviors, such as self‐scratching, have traditionally been...

Behavioral predictors of successful pairing of rhesus macaques (Macaca mulatta) at the visual contact phase of social introduction

Identification of behaviors early in the process of rhesus macaque social introductions that might predict social housing success would allow primate managers to best allocate resources and minimize animal stress by aborting introductions unlikely to lead to successful pairings. We...

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...

Validating WelfareTrak® as a tool to improve the welfare of individual chimpanzees

WelfareTrak® is a web application that gives animal care specialists the opportunity to complete weekly species‐specific surveys to monitor positive and negative indicators of welfare for individual animals. WelfareTrak® generates reports and “flags” potential shifts in welfare status. The goal...

Looking into the eyes of a cow: Can eye whites be used as a measure of emotional state? Applied Animal Behaviour Science 186, 1-6

A number of studies have looked at whether the percentage of visible eye whites could be a reliable and dynamic tool for measuring emotional state in cattle. In this study we have built upon previous research to further test this...

Contact with cows during the young age increases social competence and lowers the cardiac stress reaction in dairy calves

Separating calf and cow within 24h after birth is common practice in dairy farms. Some dairy farmers, however, practice a rearing system in which the calves are nursed by their dam or by foster cows. We investigated if dairy calves...

Dairy goats prefer to use different flooring types to perform different behaviours

Flooring is an important component of indoor housing systems for livestock as it can impact animal hygiene and welfare. Therefore, the aim of this study was to evaluate the lying and elimination preferences of goats, as well as their relative...
