Can live with ‘em, can live without ‘em: Pair housed male C57BL/6J mice show low aggression and increasing sociopositive interactions with age, but can adapt to single housing if separated

The basic question as to whether male laboratory mice should be singly or group housed represents a major animal welfare concern within current laboratory animal legislation and husbandry. To better understand the behavioural and physiological mechanisms underlying this issue, we...

Does dairy calves’ motivation for social play behaviour build up over time?

Dairy calves are often housed in individual pens, which limits play behaviour. This study investigates whether the motivation for social play builds up during periods of deprivation hereof. Sixteen mixed-sex pairs of calves (33 ± 3 days of age) were...

Attenuation of fear through social transmission in groups of same and differently aged horses

Transmission of fear and attenuation of fear within groups of farm animals remain relatively unexplored, despite the importance for human and animal safety. This paper reports the results of two separate experiments, aiming to explore social transmission of habituation in...

Female social behaviour during three male introductions in captive groups of rhesus macaques

Introductions of new males into captive primate groups are often necessary to prevent inbreeding, but also bear high social risks. To minimize these risks, it is crucial to understand the social behaviour accompanying male introductions. While the behaviour of new...

Intergenerational sex-specific transmission of maternal social experience

The social environment is a major determinant of individual stress response and lifetime health. The present study shows that (1) social enrichment has a significant impact on neuroplasticity and behaviour particularly in females; and (2) social enrichment in females can...

Breaking up is hard to do: Does splitting cages of mice reduce aggression?

Injurious aggression in group housed male laboratory mice is a common welfare issue that can also negatively affect study outcomes. Often, one mouse in the cage appears unwounded, and the current standard practice is to remove this presumed aggressor. This...

Long term benefits on social behaviour after early life socialization of piglets

Early life socialization of piglets has been shown to reduce piglet aggression at weaning, but information on sow health and long-term benefits is lacking. We aimed to assess how socialization impacts sow udder quality and long-term pig behaviour and growth....

Provision point-source materials stimulates play in sows but does not affect aggression at regrouping

When sows are mixed into groups, hierarchies form and resulting aggression and stress can affect production and welfare. This study determined the effect of providing point-source materials on aggressive and play behaviors in gestating sows. Large white cross Landrace sows...

Does group size matter? Captive chimpanzee (Pan troglodytes) behavior as a function of group size and composition

The National Institutes of Health and the Association of Zoos and Aquariums recommend that captive chimpanzees be housed in multi‐male, multi‐female, age‐diverse groups of no less than seven individuals. These recommendations are rooted in the idea that captive chimpanzee groups...

Individuals in larger groups are more successful on spatial discrimination tasks
