Effects of physical enrichment and pair housing before weaning on growth, behaviour and cognitive ability of calves after weaning and regrouping

Housing unweaned calves individually in barren environments negatively affects their growth, cognitive ability, and adaptability to environmental changes in later life. Social housing has been shown to improve those aspects, whereas physical environmental enrichment has rarely been studied in calves....

Sow behavior during introduction to a large dynamic group is influenced by familiarity and method

Sows in an extensive setting maintain small, stable matrilineal social groups comprised of familiar, and often genetically related, conspecifics. Providing conditions in an intensive farm setting which allow similar social groups could reduce aggression by allowing familiar sows to benefit...

Social buffering as a tool for improving rodent welfare

The presence of a conspecific can be calming to some species of animal during stress, a phenomenon known as social buffering. For rodents, social buffering can reduce the perception of and reaction to aversive experiences. With a companion, animals may...

Sex differences in hierarchical stability in a formation of a mixed-sex group of rhesus macaques

Forming groups of captive rhesus macaques (Macaca mulatta) is a common management practice. New formations of unfamiliar macaques can be costly, with high levels of trauma, particularly as intense aggression is used to establish a dominance hierarchy. Combining previous subgroups...

Influence of pair-housing on sleep parameters evaluated with actigraphy in female rhesus monkeys

Rhesus monkeys are naturally social animals, and behavioral management strategies have focused on promoting pairhousing in laboratory settings as an alternative to individual or group housing. In humans, co-sleeping can have a major impact on bed partners' sleep, raising the...

Single-dose diazepam administration improves pairing success of unfamiliar adult male rhesus macaques (Macaca mulatta)

Social housing is one of the best forms of environmental enhancement for nonhuman primates, and current research into pair compatibility and introduction techniques focuses on improving safety and outcome. The gradual steps method (GS), which is widely used for introducing...

Effects of social housing on dairy calf social bonding

Social housing for dairy calves has a range of benefits for social development, yet there is limited understanding of how social bonds form early in life. We characterized effects of early life social contact on the development of social preference...

Pre-exposure via wire-mesh partition reduces intraspecific aggression in male, wild-type Norway rats

There are instances when animals are introduced and expected to live alongside unfamiliar conspecifics within zoos, laboratories and wildlife sanctuaries. These pairings of unfamiliar animals may result in stress, trauma, or even death, in addition to reduced confidence in data...
