  1. Assessing walking posture with geometric morphometrics: effects of rearing environment in pigs

    Full-text: Available

    | Contributor(s):: Tallet, Céline, Sénèque, Emilie, Mégnin, Claire, Morisset, Stéphane, Val-Laillet, David, Meunier-Salaün, Marie-Christine, Fureix, Carole, Hausberger, Martine

    Rearing social animals like pigs in isolation from conspecifics can have consequences on behaviour and physiology. The aim of this experiment was to determine whether rearing conditions affect body posture. We adapted a method for quantitative evaluation of posture based on geometric...

  2. Behavioural responses of broiler chickens during low atmospheric pressure stunning

    Full-text: Available

    | Contributor(s):: Mackie, Nikki, McKeegan, Dorothy E. F.

    Low atmospheric pressure stunning (LAPS) is a new irreversible stunning method for broiler chickens ( Gallus gallus domesticus), which has the potential to improve welfare during routine slaughter. During LAPS, birds are placed in a hypobaric chamber that allows oxygen to be gradually removed...

  3. Effects of stocking rate on measures of efficacy and welfare during argon gas euthanasia of weaned pigs

    | Contributor(s):: Fiedler, K. J., Parsons, R. L., Sadler, L. J., Millman, S. T.

    The objective of this study was to evaluate the effects of chamber stocking rate on facets of animal welfare and efficacy during euthanasia of weaned pigs ( Sus scrofa domesticus) with argon gas. Two hundred and thirty-three weaned pigs designated for euthanasia at a commercial production farm...

  4. Making the case for developing alternative lameness scoring systems for dairy goats

    | Contributor(s):: Vieira, A., Oliveira, M. D., Nunes, T., Stilwell, G.

    Lameness is a behavioural indicator of pain that negatively affects dairy ruminants' health and welfare. Lameness is generally assessed by subjective methods, based on the observation of the animal's behaviour, using numerical rating scales (NRSs) - the most common scoring system - and visual...

  5. Does hippotherapy effect use of sensory information for balance in people with multiple sclerosis?

    | Contributor(s):: Lindroth, J. L.

  6. The effect of four different feeding regimes on rabbit behaviour

    | Contributor(s):: Prebble, J. L., Langford, F. M., Shaw, D. J., Meredith, A. L.

    Dietary composition and presentation impacts on the behaviour of animals, and failure to provide a suitable diet can lead to reduced welfare through the development of poor health, the inability to express normal behaviours and the development of abnormal behaviours. This study assessed the...

  7. Urinary posture and motor laterality in dogs ( Canis lupus familiaris) at two shelters

    | Contributor(s):: Gough, W., McGuire, B.

    Motor laterality is the preference shown for using one limb or lateral half of the body over the other. In domestic dogs, most laterality studies have examined forelimb preferences during staged tasks. We focused instead on hindlimb preferences during urination when males use the raised-leg...

  8. The effect of physical contact between dairy cows and calves during separation on their post-separation behavioural response

    | Contributor(s):: Johnsen, J. F., Ellingsen, K., Grondahl, A. M., Boe, K. E., Lidfors, L., Mejdell, C. M.

    Premature breaking of the maternal bond between a cow and her calf triggers a strong behavioural response which renders separation and weaning major welfare challenges in suckling systems. Fence-line separation and weaning allowing physical contact has been evaluated for beef cattle and is...

  9. Effects of growth-promoting technology on feedlot cattle behavior in the 21 days before slaughter

    | Contributor(s):: Stackhouse-Lawson, K. R., Tucker, C. B., Calvo-Lorenzo, M. S., Mitloehner, F. M.

    There is growing interest in the animal welfare implications of growth-promoting technology used in feedlot cattle, namely hormonal implants, ionophores, antibiotics and β 2-adrenergic agonists. Previous studies have focused on the effects of implants on aggression, but little work has...

  10. Internet-based home training is capable to improve balance in multiple sclerosis: a randomized controlled trial

    | Contributor(s):: Frevel, D., Maurer, M.

  11. The effects of human age, group composition, and behavior on the likelihood of being injured by attacking pumas

    | Contributor(s):: Coss, R. G., Fitzhugh, L. E., Schmid-Holmes, S., Kenyon, M. W., Etling, K.

    Documentation from the years 1890 to 2000 of 185 instances of pumas (Puma concolor) attacking humans in the United States and Canada has provided statistical evidence that pumas are less likely to kill or injure humans in certain circumstances. We identified incidents of fatal attacks, severe...

  12. Down but not out: supine postures as facilitators of play in domestic dogs

    | Contributor(s):: Norman, K., Pellis, S., Barrett, L., Henzi, S. P.

    We used two sets of videotaped data of playing domestic dog dyads to determine whether rolling over during play served as a signal of submission or whether it was a combat maneuver adopted as part of an ongoing play sequence. Our results provide strong support for the latter. In the absence of...

  13. Effect of enclosure size and complexity on the behaviors of captive chimpanzees ( Pan troglodytes )

    | Contributor(s):: Jensvold, M. L. A., Sanz, C. M., Fouts, R. S., Fouts, D. H.

    Reports describing the implementation of innovative facility designs are important to both the primate caregiving community and policymakers reviewing current U.S. Department of Agriculture regulations. This study documents the changes in behaviour of 5 adult chimpanzees that coincided with...

  14. Effects of stocking rate on measures of efficacy and welfare during carbon dioxide gas euthanasia of young pigs

    | Contributor(s):: Fiedler, K. J., Parsons, R. L., Sadler, L. J., Millman, S. T.

    The objective of this study was to evaluate the effects of chamber stocking rate on facets of animal welfare and efficacy during gas euthanasia of young pigs ( Sus scrofa domesticus). Crossbred pigs (390 neonatal and 270 weaned) designated for euthanasia at production farms were randomly assigned...

  15. Welfare by the ear: comparing relative durations and frequencies of ear postures by using an automated tracking system in sheep

    | Contributor(s):: Vogeli, S., Wechsler, B., Gygax, L.

    Given the increased interest in animal emotional reactions for assessing welfare, indicators for such reactions are sought. Ear postures and movements have been found to be promising indicators of emotional states in sheep and other animals. The manual recording of ear postures, however, is very...

  16. Equine assisted activities and therapies: A case study of an older adult

    | Contributor(s):: Wehofer, Lisa, Goodson, Nicole, Shurtleff, Tim L.

  17. Dogs' features strongly affect people's feelings and behavior toward them

    | Contributor(s):: Gazzano, A., Zilocchi, M., Massoni, E., Mariti, C.

    Dogs are a strong appeal for people. The aim of this research was to assess whether different dog features affect people's feelings and behavior toward them. Three puppies (1 Labrador retriever, 1 golden retriever, and 1 Border collie), 7 average adult dogs (3 small, 2 medium, and 2 large), and 2...

  18. Interpretation of dog behavior by children and young adults

    | Contributor(s):: Lakestani, N. N., Donaldson, M. L., Waran, N.

    This study investigates people's ability to interpret dog behavior. Inability to interpret dog behavior correctly may be a factor contributing to young children's higher likelihood of being bitten by dogs. Children (4- to 10-year-olds) and adults (total n=550) watched videos of dogs displaying...

  19. The effect of physiotherapy intervention to the pelvic region of experienced riders on seated postural stability and the symmetry of pressure distribution to the saddle: a preliminary study

    | Contributor(s):: Nevison, C. M., Timmis, M. A.

    It is commonplace for trainers and judges to comment that riders are "crooked" or "collapsed in the hip." This asymmetrical posture will likely have a significant effect on stability/balance and may subsequently have a detrimental effect on performance. Although the effects of asymmetry on...

  20. Effect of hippotherapy on motor control, adaptive behaviors, and participation in children with autism spectrum disorder: a pilot study

    | Contributor(s):: Ajzenman, H. F., Standeven, J. W., Shurtleff, T. L.
