Investigating potential effects of the contraceptive Implanon on the behavior of free-ranging adult female Barbary macaques
Contributor(s):: Maijer, A. M., Semple, S.
In recent years, the use of hormonal contraception in captive, free-ranging, and wild mammal populations has increased, but the effects on these nonhuman animals' behavior and the associated welfare impacts remain poorly understood. This study of free-ranging adult female Barbary macaques (...
Behaviour, wounds, weight loss and adrenal weight of rabbit does as affected by semi-group housing
Contributor(s):: Buijs, S., Maertens, L., Hermans, K., Vangeyte, J., Tuyttens, F. A. M.
Group housing is often assumed to improve the welfare of gregarious species. Whether this is actually the case depends on the advantages (e.g. more opportunity for social and locomotor behaviour) and disadvantages (e.g. increased fighting and wounding) induced by the specific housing type. We...
Hair plucking in captive bonobos ( Pan paniscus)
Contributor(s):: Brand, C. M., Marchant, L. F.
Both wild and captive studies of grooming in non-human primates emphasize the adaptive role of this behavior. Indeed, social grooming is frequently characterized as "social glue" in the life of primates. Grooming behavior is studied to reveal dominance, kin relations, and social networks. Many...

Identifying environmental and management factors that may be associated with the quality of life of kennelled dogs ( Canis familiaris)
Contributor(s):: Kiddie, J., Collins, L.
This paper describes the use of a validated quality of life assessment tool (described elsewhere) to identify environmental and management factors that may affect quality of life in dogs kennelled in rehoming centres. Dogs were allocated to one of the four treatment groups, all of which had a...

The effect of nursing on the cow-calf bond
Contributor(s):: Johnsen, J. F., Passille, A. M. de, Mejdell, C. M., Boe, K. E., Grondahl, A. M., Beaver, A., Rushen, J., Weary, D. M.
Dairy calves are often separated from the cow soon after birth and prevented from nursing, but little is known about the effects of nursing on the development of the cow-calf bond. This study evaluated the effect of nursing on affiliative behaviours between the dam and her calf including...
The power of automated behavioural homecage technologies in characterizing disease progression in laboratory mice: a review
Contributor(s):: Richardson, C. A.
Behavioural changes that occur as animals become sick have been characterized in a number of species and include the less frequent occurrence of 'luxury behaviours' such as playing, grooming and socialization. 'Sickness behaviours' or behavioural changes following exposure to infectious agents,...

Social housing of non-human primates in a research facility: socialisation across macaque species and sexes
Contributor(s):: Rehrig, A., DiVincenti, L., Jr., Schery, L. A.
Refinement of social housing practices is paramount to improving animal welfare in laboratory environments, especially with regard to non-human primates. Even though social housing of the same species should be considered the optimal paradigm, cynomolgus ( Macaca fascicularis) and rhesus macaques...
Washing the dog reduces dog allergen levels, but the dog needs to be washed twice a week
out of 5 stars
Contributor(s):: Tessa Hodson, Adnan Custovic, Angela Simpson, Martin Chapman, Ashley Woodcock, Rosalind Green
Background: Many asthmatic patients allergic to dogs refuse to part with their dog, and it is essential to develop techniques for lowering exposure with a dog in the home. Objective: This study investigated the effect of dog washing on the subsequent recovery of Can f 1 from...

Bobcat ( Lynx rufus ) breeding in captivity: the importance of environmental enrichment
Contributor(s):: Molla, M. I., Quevedo, M. A., Castro, F.
Environmental enrichment is an improvement in the biological functioning of nonhuman animals in captivity resulting from modifications to their environment; however, specifying appropriate and practical measures of enrichment is problematic. This study analyzes the behavior of 4 bobcats (Lynx...
Evaluating paint rollers as an intervention for alopecia in monkeys in the laboratory ( Macaca nemestrina )
Contributor(s):: Runeson, E. P., Lee, G. H., Crockett, C. M., Bellanca, R. U.
Adult female macaques (Macaca nemestrina) in the laboratory with alopecia from known or suspected overgrooming were subjects in a study evaluating effectiveness of a grooming device. The intervention evaluated was a paint roller on a metal bar hung on the cage, replaced weekly for 6 weeks. In a...
Function of tongue-playing of cattle in association with other behavioral and physiological characteristics
Contributor(s):: Ishiwata, T., Uetake, K., Eguchi, Y., Tanaka, T.
To study the function of tongue-playing of cattle, this study observed 71 Japanese Black x Holstein steers after feeding in 2 repetitive experiments. The number of steers who performed tongue-playing did not differ among the 3 levels of environmentally enriched pens. Most (90.6%) performances of...
Pair housing for female longtailed and rhesus macaques in the laboratory: behavior in protected contact versus full contact
Contributor(s):: Baker, K. C., Crockett, C. M., Lee, G. H., Oettinger, B. C., Schoof, V., Thom, J. P.
Pair housing for caged macaques in the laboratory generally allows unrestricted tactile contact but, less commonly, may involve limited contact via grooming-contact bars or perforated panels. The purpose of using this protected contact housing, which prevents entry into pair-mates' cages,...
The effect of the captive environment on activity of captive cotton-top tamarins ( Saguinus oedipus )
Contributor(s):: Burrell, A. M., Altman, J. D.
This study examined captive cotton-top tamarin (Saguinus oedipus) behaviour across 3 different exhibits: (a) a rain forest (30.5 m in diameter), where tamarins free-ranged with other species; (b) a caged outdoor exhibit (5 m in diameter); and (c) a caged enclosure, with access indoors (6x9 m) and...
Critical care and survival of fragile animals: the case of Prrxl1 knockout mice
Contributor(s):: Monteiro, C., Dourado, M., Matos, M., Duarte, I., Lamas, S., Galhardo, V., Lima, D.
The generation of genetically modified animal models in which a given gene is permanently deleted or overexpressed, sometimes results in fragile phenotypes characterized by high morbidity and premature death. This undesired outcome creates important welfare difficulties and poses a huge...
The effect of conspecific removal on the behaviour and physiology of pair-housed shelter dogs
Contributor(s):: Walker, J. K., Waran, N. K., Phillips, C. J. C.
Dogs ( Canis familiaris) are a highly social species and within a shelter environment pair-housing is recommended to prevent the stress associated with social isolation. Separation of individuals which may have formed bonds in this environment is a usual occurrence, as a result of rehoming or...
