  1. Survey of breeders' management of horses in Europe, North America and Australia: comparison of factors associated with the development of abnormal behaviour

    Contributor(s):: Parker, M., Goodwin, D., Redhead, E. S.

    An online survey of domestic horse breeders in the USA, UK, Australia, Canada and mainland Europe was carried out in order to examine management risk factors associated with the development of abnormal behaviour patterns. One hundred and forty breeders responded, and epidemiological results...

  2. The effects of weaning at 7, 14 and 28 days on piglet behaviour

    Contributor(s):: Worobec, E. K., Duncan, I. J. H., Widowski, T. M.

    The effects of very early weaning on piglet behaviour were investigated. In order to determine the effects of weaning age on piglet behaviour, litters of piglets were randomly assigned to be weaned at 7, 14 and 28 days of age. In each of 3 trials, piglets from 3 litters were mixed into 2 pens of...

  3. The social transmission of feather pecking in laying hens: effects of environment and age

    Contributor(s):: McAdie, T. M., Keeling, L. J.

    Abnormal behaviours, such as feather pecking, can become an even greater problem if they spread through the flock. Domestic hens are a social species and it has been suggested that feather pecking behaviour can be socially transmitted from few feather pecking individuals to many. The purpose of...

  4. The treatment of phobias in the dog

    Contributor(s):: Walker, R., Fisher, J., Neville, P.

    Since 1992 the authors have been compiling a casebook of detailed histories of canine phobia. As the work progressed modifications were made to the diagnostic criteria of anxiety in the dog. A combination of phenobarbitone with propranolol was used with perceived success supported by anecdotal...

  5. The use of mirrors for the control of stereotypic weaving behaviour in the stabled horse

    Contributor(s):: McAfee, L. M., Mills, D. S., Cooper, J. J.

    Weaving, a common locomotor stereotypy, is associated with social isolation in stabled horses. In this study we investigated the effect of provision of mirrors on weaving as this may have a similar effect to access to conspecifics. The behaviour of 6 known weavers, each in 1 of 3 locations within...

  6. Treating canine and feline behaviour problems and advising clients

    Contributor(s):: Turner, D. C.

    In this introductory paper, pet behaviour counselling and therapy is considered. A case is made for cooperation between veterinarians and trained pet behaviour advisors and for qualification of professionals working in the field. The general causes of behaviour problems, as well as general...

  7. Veterinary behavioural medicine. Selected papers presented at the 5th Biennial International Conference on Veterinary Behavioural Medicine, Minneapolis, Minnesota, USA, 14-16 July 2005

    Contributor(s):: Mills, D., Landsberg, G.

    This issue contains papers on normal behaviour and behavioural problems of dogs and approaches on how to manage these problems, including training and drug therapy.

  8. What time is feeding? How delays and anticipation of feeding schedules affect stump-tailed macaque behavior

    Contributor(s):: Waitt, C., Buchanan-Smith, H. M.

    Everyday animal care routines are essential to an animal's physical well-being but the effects of husbandry routines on the animals' psychological well-being are not often considered. The scheduling of animal care routines may have an important impact on how they are perceived by the animals...

  9. A behavioural comparison of New Zealand White rabbits ( Oryctolagus cuniculus ) housed individually or in pairs in conventional laboratory cages

    Contributor(s):: Chu, L. R., Garner, J. P., Mench, J. A.

    Despite their gregarious nature, rabbits used for research are often housed individually due to concerns about aggression and disease transmission. However, conventional laboratory cages restrict movement, and rabbits housed singly in these cages often perform abnormal behaviours, an indication...

  10. A behavioural study of scrapie-affected sheep

    Contributor(s):: Healy, A. M., Hanlon, A. J., Weavers, E., Collins, J. D., Doherty, M. L.

    The behaviour of 12 sheep, suspected of having scrapie, and 12 clinically normal animals from the Irish Republic was observed over a 6-day period [date not given]. Confirmation of the true disease status of the animals was made at postmortem using both histopathological and immunocytochemical...

  11. A note on aggression and cannibalism in laying hens following re-housing and re-grouping

    Contributor(s):: Cloutier, S., Newberry, R. C.

    The effects of being moved and mixed with strangers on the incidence of aggression and cannibalism in caged White Leghorn hens with intact beaks were examined. It was predicted that mixing of strangers would increase rates of aggression and cannibalism. Hens were reared in 16 stable groups of...

  12. An evaluation of response to novelty as a predictor of pecking tendency in laying hens

    Contributor(s):: Albentosa, M. J., Glen, E., Leeb, C., Whittaker, X., Nicol, C. J.

    Selective breeding against feather pecking in laying hens depends on identification of individual birds with the lowest feather pecking activity. If certain behavioural traits are phenotypically and genetically associated with, or predictive of, feather pecking activity then tests for these...

  13. Behavior and cortisol levels of dogs in a public animal shelter, and an exploration of the ability of these measures to predict problem behavior after adoption

    Contributor(s):: Hennessy, M. B., Voith, V. L., Mazzei, S. J., Buttram, J., Miller, D. D., Linden, F.

    Behaviour and plasma cortisol levels were examined in puppies and juvenile/adult dogs admitted to a public animal shelter. A behavioural test was developed to assess the responses of the dogs to novel or threatening conditions. Factor analysis of the behavioural responses of 166 dogs on day 3 in...

  14. Behavior of picketed circus elephants

    Contributor(s):: Friend, T. H.

    The behaviour of 14 female Asian (Elephas maximus) and 3 female African (Loxodonta africana) elephants who performed 2 shows each day with a circus that travelled to a new location (40 to 250 km from the previous day's lot) daily, was studied. When not performing or working, the elephants were...

  15. Behavioral and environmental factors associated with elimination behavior problems in cats: a retrospective study

    Contributor(s):: Horwitz, D. F.

    Data from 100 house soiling cats were reviewed. These cats had been referred to a clinic due to depositing urine, stool, urine and stool or spraying in the home. The information was contrasted and compared to similar information collected on 44 cats that did not have a history of persistent house...

  16. Behavioural and physiological responses to an acute stressor in crib-biting and control horses

    Contributor(s):: Bachmann, I., Bernasconi, P., Herrmann, R., Weishaupt, M. A., Stauffacher, M.

    The responses of eleven pairs of crib-biting and non-crib-biting horses (controls) to an arousal-inducing stimulus were studied. Video-observation of the horses revealed that crib-biting horses spent between 10.4 and 64.7% of their stabling time performing the stereotypy. During the first 2 days...

  17. Behavioural research in zoos: academic perspectives

    Contributor(s):: Hosey, G. R.

    A survey of papers published in Zoo Biology between 1989 and 1994 showed that 40% of papers were behavioural studies, but only 35% of these reported basic research. Most papers were authored by zoo researchers (58%), either with or without an academic collaborator. A similar survey of Animal...

  18. Buller steer syndrome review

    Contributor(s):: Blackshaw, J. K., Blackshaw, A. W., McGlone, J. J.

  19. Canine dominance-associated aggression: concepts, incidence, and treatment in a private behavior practice

    Contributor(s):: Cameron, D. B.

    A review of 35 dominance-associated aggression (DA) cases presented to a small, private, behaviour-only veterinary practice revealed that attention addiction was the most commonly associated (66

  20. Comparison of dogs' reactions to four different head collars

    Contributor(s):: Haug, L. I., Beaver, B. V., Longnecker, M. T.

    Head collars are widely used in canine behaviour modification programmes. Owner compliance is crucial for success and depends in part on the dog's acceptance of the product. The responses of 12 dogs to 4 different head collars were compared in a crossover design over four 10 min sessions each...
