    Contributor(s):: Vandeleest, Jessica J., McCowan, Brenda, Capitanio, John P.

    Laboratory and zoo housed non-human primates sometimes exhibit abnormal behaviors that are thought to reflect reduced well-being. Previous research attempted to identify risk factors to aid in the prevention and treatment of these behaviors, and focused on demographic (e.g. sex or age) and...

    To examine the effects of milk allowance and weaning age on cross-sucking, 45 dairy calves were housed in groups of nine and fed milk and grain-based starter feed from automated feeders and allocated to three treatment groups: (A) Low-Milk Early-Weaned (fed 6L/d of milk until weaned at 47 d of...

  4. Comparing the relative benefits of grooming-contact and full-contact pairing for laboratory-housed adult female Macaca fascicularis

    Contributor(s):: Lee, Grace H., Thom, Jinhee P., Chu, Katherine L., Crockett, Carolyn M.

    Tactile social contact is the most effective form of environmental enrichment for promoting normal behavior in captive primates. For laboratory macaques housed indoors, pair housing is the most common method for socialization. Pairs can be housed either in full contact (FC), or in protected...

  13. Reconsidering coprophagy as an indicator of negative welfare for captive chimpanzees

    Contributor(s):: Hopper, Lydia M., Freeman, Hani D., Ross, Stephen R.

    For captive chimpanzees, 'abnormal' behaviours include behaviours observed only in captivity (i.e. species-atypical behaviours) and those that are performed at higher rates in captivity compared to in the wild. Both types are used as metrics for evaluating captive primates' welfare....

  15. The Swedish Swan Lady: reaction to an apparent animal hoarding case

    Contributor(s):: Svanberg, I., Arluke, A.

    This study describes media and judicial reaction to the first publicly acknowledged case of animal hoarding in Sweden-a 60-year-old Swedish woman who purportedly "rescued" 150 swans over several years by bringing many back to her one-room apartment. Reports in the press and social media reflected...

  16. Abnormal behaviour and behavioural problems in stabled horses and their relationship to horse welfare: a comparative review.

    Contributor(s):: G.j. Mason, J. Cooper

    Many behaviours in domestic animals, such as the ‘stable vices’ of horses, are treated because they are considered undesirable for economic or cultural reasons, and not because the activity affects the horse’s quality of life. The impact of a behaviour on the human reporter is...

    Contributor(s):: Wagner, K., Owen, S., Burke, T. W.

    The purpose of this research was to explore the perceived seriousness of crimes, such as abuse and neglect, committed against nonhuman animals. Drawing upon the methods of previous work on crime seriousness, it was hypothesized that perceptions of the harmfulness and wrongfulness of animal...

  20. Behavioural consequences of visual deprivation occurring at hatch or in the early life of chickens


    The development of behaviour in a line of chickens that are born sighted ( rdd) but turn blind after hatching was compared with a line that is blind at hatch ( beg) and with sighted White Leghorn controls (WL) to test the hypothesis that birds that become blind later in their life will show...
