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...
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...
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...
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...
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...
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...
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...
Social housing is always preferred in the research environment; however, single housing is sometimes necessitated by scientific objectives or social incompatibility. In these cases, other environmental enhancements are developed to provide indirect social interactions. We...
It is important to evaluate the effectiveness of environmental enrichment in meeting behavioral goals (e.g., decreasing abnormal behavior) and in making the best use of limited facility resources (e.g., money, personnel time). One/zero behavioral data...
Effective environmental enrichment encourages usage, promotes species‐typical behaviors, and/or decreases abnormal behaviors. Porches are small cages that attach to the primary cage of an animal to provide additional space and a better view of the...
