Social experience, behavior and stress in guinea pigs

Guinea pigs require considerable socialisation to acquire the skills necessary to build up stable social structures. If rearing conditions are inadequate this creates conditions of social instability and extreme endocrine changes occur.

Social experience, behaviour, stress and health in guinea pigs

These data suggest that guinea pigs require considerable socialisation to acquire the skills necessary to build up stable social structures. If rearing conditions are inadequate this creates conditions of social instability and extreme endocrine changes occur.

Environmental enrichment for laboratory mice (Mus musculus)

It must be considered as doubtful whether the current bland and unenriched laboratory animal cage environment is either sufficient or able to fulfill the legitimate requirements of this species. Water bottles containing sawdust provide effective cage enrichment for laboratory mice....

Of mice and kin: The functional significance of kin bias in social behaviour

Mice tend to be intolerant of same sex partners at the time of puberty. It is, therefore good advice to establish same sex groups well before the onset of puberty.

Group-size, cage shelf level, and emotionality in nonobese diabetic mice?Impact on onset and incidence of IDDM

Emotionality' or 'fearfulness' is higher in mice housed in steel cages at the top of the rack than at the middle of bottom of the rack.Incident and reflected light decreased from the top to the bottom of the rack.

Antibody response to rat erythrocytes and some behaviors in two strains of mice after social isolation

Social isolation (of adult mice) influenced emotional behavior [under frightening conditions], but not the antibody response [to rat erythrocytes].

Body weight and water intake of guinea pigs: influence of single caging and an unfamiliar new room

No changes in body weight are observed if adult male guinea pigs are removed from their groups and kept singly in their home enclosure. In contrast, subjects markedly lose weight and show a marked reduction of water intake if isolated...

Increased plasma ACTH responses to stress in nonhandled compared with handled rats require basal levels of corticosterone and are associated with increased levels of ACTH secretagogues in the median eminence

Handling of rat pups produced siginificantly lower plasma ACTH responses to a variety of stressors compared to nonhandled pups.
