  1. White Blood Cell Counts, Parasite Prevalence, and Plasma Cortisol Levels of Dogs in a County Animal Shelter: Changes over Days and Impact of a Program of Repeated Human Interaction

    Contributor(s):: Emily S. Dudley

    Animal shelter housing is highly stressful for a dog, compromising welfare and leading to undesirable behaviors and unknown health consequences. We documented the changes in circulating numbers of white blood cells, plasma cortisol, and fecal parasite shedding of dogs housed for 10 days at a...

  2. Effects of stage of gestation at mixing on aggression, injuries and stress in sows

    Contributor(s):: Stevens, B., Karlen, G. M., Morrison, R., Gonyou, H. W., Butler, K. L., Kerswell, K. J., Hemsworth, P. H.

    Confinement of breeding sows to stalls is a controversial welfare issue, and there is a worldwide move to house gestating sows in groups. We examined the effects of day of mixing following insemination on aggression, injuries and stress in sows. A total of 800 sows were used in this experiment...

  3. Cohabitation with a sick cage mate: Effects on noradrenaline turnover and neutrophil activity

    Contributor(s):: Alves, Glaucie Jussilane, Vismari, Luciana, Florio, Jorge Camilo, Palermo-Neto, João

  4. Effects of exposing pigs to moving and odors in a simulated slaughter chute

    Contributor(s):: Krebs, N., McGlone, J. J.

    Pigs in the finishing stage are infrequently handled and can be difficult to handle when experiencing novel situations. This study sought to determine the effects of minimal training and a novel odor/taste reward on the ease of handling finishing pigs in a novel environment. Pigs were assigned to...

  5. Effects of social "stressors" on belly-nosing behaviour in early-weaned piglets: is belly-nosing an indicator of stress?

    Contributor(s):: Gardner, J. M., Duncan, I. J. H., Widowski, T. M.

    Belly-nosing is a behaviour pattern commonly observed in early-weaned piglets. Although belly-nosing has been referred to as an indicator of stress, the factors involved in its causation are unknown. The objective of this study was to determine if the differences in stress at weaning influence...

  6. Outdoor housing of laboratory dogs: effects on activity, behaviour and physiology

    Contributor(s):: Spangenberg, E. M. F., Bjorklund, L., Dahlborn, K.

    Laboratory dogs are mainly housed indoors and outdoor housing is often considered to be an insecure and uncontrollable alternative. This study aimed to assess the effects of outdoor housing of laboratory dogs on their general physiology, activity and activity-related behaviours. Eight male...

  7. Adrenocorticotrophin-induced stress response in captive vicunas ( Vicugna vicugna ) in the Andes of Chile

    Contributor(s):: Bonacic, C., Macdonald, D. W., Villouta, G.

    The vicuna is mainly used in two ways: wild captured, shorn and returned to the wild; or wild captured and maintained in captivity as part of a programme of sustainable use in the Andes of South America. Farming of wild vicunas has hitherto involved no assessment of their welfare. In this study a...

  8. Assessment of stress in non-human primates: application of the neutrophil activation test

    Contributor(s):: Honess, P. E., Marin, C., Brown, A. P., Wolfensohn, S. E.

    A technique measuring leukocyte (neutrophil) activity was used to examine differences between stress levels in a breeding colony of rhesus macaques housed in either a traditional caging system or open-rooms. The leukocyte activation test measured the degree to which blood from the two treatment...

  9. The effect of transport on cortisol, glucose, heart rate, leukocytes and body weight in captive-reared guanacos ( Lama guanicoe )

    Contributor(s):: Zapata, B., Gimpel, J., Bonacic, C., Gonzalez, B. A., Riveros, J. L., Ramirez, A. M., Bas, F., Macdonald, D. W.

    Current procedures for ranching and sustainable use of guanacos necessitate their transport. Transportation is a risky process for animals, and is a particular concern for wild-caught or semi-domesticated species such as the guanaco - a wild South American camelid species increasingly being...

  10. The effect of transport stress on neutrophil activation in wild badgers ( Meles meles )

    Contributor(s):: Montes, I., McLaren, G. W., Macdonald, D. W., Mian, R.

    Wild badgers (Meles meles) in Wytham woods, Oxfordshire, are routinely trapped, transported to a central field laboratory, studied and released as part of an on-going population study. These procedures have been carefully developed to minimize impact on the badgers' welfare; however they are...

  11. The physiological impact of wool-harvesting procedures in vicunas ( Vicugna vicugna )

    Contributor(s):: Bonacic, C., Macdonald, D. W.

    A current programme of wildlife utilization in the Andean region involves the capture of wild vicunas, their shearing, transport and, in some cases, captive farming. The effects of these interventions on the physiology, and thus welfare, of wild vicunas are unknown. As a first step to quantifying...
