  1. Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour

    Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.

    Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...

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

    Contributor(s):: Tallet, C., Seneque, E., Megnin, C., Morisset, S., Val-Laillet, D., Meunier-Salaun, M. C., Fureix, C., Hausberger, M.

    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...

  3. What is a canine athlete?

    Contributor(s):: Zink, M. C., Dyke, J. B. van

    Canine sports medicine and rehabilitation is the newest specialty in veterinary medicine. It encompasses and integrates a variety of fields, including orthopedics, exercise physiology, neurology, cardiology, pulmonology, nutrition, and others. Rehabilitation, which includes conditioning...

  4. Adopter-dog interactions at the shelter: behavioral and contextual predictors of adoption

    Contributor(s):: Protopopova, A., Wynne, C. D. L.

    Millions of unwanted pets enter animal shelters each year in the USA, but only a portion leave alive. Previous research has found that morphology and in-kennel behavior influence adoption. The current study evaluated whether any behaviors exhibited by dogs during an out-of-kennel interaction with...

  5. A pilot study of sexual dimorphism in the head morphology of domestic dogs

    Contributor(s):: Carrasco, J. J., Georgevsky, D., Valenzuela, M., McGreevy, P. D.

    The dog ( Canis lupus familiaris) displays more morphological diversity than any other species. It is a direct descendant of the gray wolf ( Canis lupus), but shows remarkable behavioral and morphological differences. It has been suggested that differences in skull shape that relate to brain...

  6. 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...

  7. Stress measures in tail biters and bitten pigs in a matched case-control study

    Contributor(s):: Munsterhjelm, C., Brunberg, E., Heinonen, M., Keeling, L., Valros, A.

  8. Visual discrimination learning and spatial acuity in sheep

    Contributor(s):: Sumita, Sugnaseelan, Prescott, N. B., Broom, D. M., Wathes, C. M., Phillips, C. J. C.

  9. A cross-cultural comparison of reports by German Shepherd owners in Hungary and the United States of America

    Contributor(s):: Wan, M., Kubinyi, E., Miklosi, A., Champagne, F.

    Cross-cultural comparisons of dog behavior and dog-keeping practices are limited. The current study compared the questionnaire responses of German Shepherd owners in Hungary and the United States of America (USA). Owners provided information about their dog-keeping practices, as well as reports...

  10. A note on hair whorl position and cattle temperament in the auction ring

    Contributor(s):: Lanier, J. L., Grandin, T., Green, R., Avery, D., McGee, K.

    The objective of this study was to further describe the relationships between facial hair whorls and temperament in cattle. Cattle (n=1636) from 6 commercial cattle auctions in Colorado and Texas, USA [date not given] were observed. Whorl location was classified according to lateral position...

  11. Social strategies associated with identity profiles in dairy goats

    Contributor(s):: Miranda-de la Lama, G. C., Sepulveda, W. S., Montaldo, H. H., Maria, G. A., Galindo, F.

    The aim of this study was to identify and analyse the social strategies associated with dominance, conflict resolution, individual behaviour and morphological traits in goats. Social interactions of 30 high-yielding dairy goats were recorded over a period of 16 days for 96 h. The variables...

  12. Addressing pain caused by mulesing in sheep. (Special Issue: Pain in farm animals.)

    Contributor(s):: Fisher, A. D.

    The surgical operation of mulesing cuts wool-bearing and wrinkled skin from the perineal region and adjoining hindquarters of Australian Merino sheep, and has been shown in combination with tail docking to provide significantly enhanced protection against flystrike for the remainder of the...

  13. The presence of mind: on reunifying the animal mind and body

    Contributor(s):: McMillan, F. D., Rollin, B. E.

  14. Height to withers and abdominal circumference effects on diets of grazing goats

    Contributor(s):: Mellado, M., Rodriguez, A., Villarreal, J. A., Lopez, R.

    Diet selection in an arid rangeland of northern Mexico by short (height to withers 77 cm) multiparous non-pregnant, non-lactating does and the diets of multiparous non-pregnant, non-lactating does with reduced (101 cm) abdominal circumference is described from microhistological analysis of fecal...

  15. Time spent in shade and its relationship with physiological factors of thermoregulation in three breeds of cattle

    Contributor(s):: Bennett, I. L., Finch, V. A., Holmes, C. R.

    Six Brahman, 6 Shorthorn and 6 Brahman X Hereford X Shorthorn steers were kept in a yard which consisted of 4 areas exposed to direct sunlight and 3 shaded areas covered by canopies which reduced the transmission of direct solar radiation by 50, 70 and 80% (low-, medium- and high-shade areas...

  16. Challenges and paradoxes in the companion-animal niche

    Contributor(s):: McGreevy, P. D., Bennett, P. C.

    By definition, the companion-animal niche demands merely that animals must provide companionship. At first glance, this may seem easy enough, but the forces that contribute to success in this niche are complex. Indeed, success as a companion is rarely measured in terms of biological fitness, and...

  17. Welfare epidemiology as a tool to assess the welfare impact of inherited defects on the pedigree dog population

    Contributor(s):: Collins, L. M., Asher, L., Summers, J. F., Diesel, G., McGreevy, P. D.

    The effect that breed standards and selective breeding practices have on the welfare of pedigree dogs has recently come under scrutiny from both the general public and scientific community. Recent research has suggested that breeding for particular aesthetic traits, such as tightly curled tails,...

  18. What factors should determine cage sizes for primates in the laboratory?

    Contributor(s):: Buchanan-Smith, H. M., Prescott, M. J., Cross, N. J.

    It is imperative to provide adequate quantity and quality of space for all captive animals. Yet practically all guidelines on the housing of primates in the laboratory specify minimum cage sizes based solely on body weight. We argue that no single factor, such as body weight, is sufficient to...
