  1. Medical paradigms for the study of problem behaviour: a critical review. (International Society for Applied Ethology Special Issue)

    Contributor(s):: Mills, D. S.

    The study of animal behaviour problems is an area of increasing interest in applied ethology. As with the study of abnormal behaviour in humans, there are two broad approaches to this subject, one emphasising the role of the environment and biology of the species in shaping behaviour and other...

  2. 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...

  3. Factors associated with the prevalence of stereotypic behaviour amongst Thoroughbred horses passing through auctioneer sales

    Contributor(s):: Mills, D. S., Alston, R. D., Rogers, V., Longford, N. T.

    The objective of this study was to evaluate whether sex, age and/or coat colour were associated with the occurrence of stereotypic behaviour in the horse and to assess whether the occurrence of one type of stereotypy in an individual was associated with the occurrence of another specific type of...

  4. A study of cortisol and beta-endorphin levels in stereotypic and normal Thoroughbreds

    Contributor(s):: Pell, S. M., McGreevy, P. D.

    Plasma and salivary cortisol levels were measured in stereotypic (n=46) and normal horses (n=46). No significant differences were found between the 2 groups of horses. The correlation between plasma and salivary cortisol concentrations of individual horses (n=66) was also examined. A significant...

  5. Resting and social behaviour of dairy heifers housed in slatted floor pens with different sized bedded lying areas

    Contributor(s):: Nielsen, L. H., Mogensen, L., Krohn, C., Hindhede, J., Sorensen, J. T.

    The hypothesis that an increase in the straw bedded resting area for group housed heifers would increase synchronization of resting behaviour and decrease aggressive and abnormal behaviour was tested. An experiment was conducted on 2 Danish commercial dairy farms with 20 Danish Friesian heifers...

  6. Canine fears and phobias; a regime for treatment without recourse to drugs

    Contributor(s):: Rogerson, J.

    From a study of 247 (102 male dogs and 145 bitches) case histories presenting varying degrees of fear and phobia, both generalised and specific, it has been possible to define standard patterns of behaviour. This was done on the basis of severity of the fear, the type of fear response displayed...

  7. Dustbathing and feather pecking in domestic chickens reared with and without access to sand

    Contributor(s):: Norgaard-Nielsen, G.

    Eight groups of 10 female white Leghorn chicks were kept in wire floor cages from 1 day old. From 2 days of age four of the groups had continuous access to a wooden tray with dark dry sand, while the other groups had a wooden frame of the same size but without sand. Low intensity light (10 lux)...

  8. Motivational and physiological analysis of the causes and consequences of non-nutritive sucking by calves

    Contributor(s):: Passille, A. M. de, Rushen, J.

    Non-nutritive sucking by calves of an artificial, dry teat was examined. Most non-nutritive sucking occurred directly after a meal and was elicited by the taste of milk. Increasing the volume of milk drunk did not reduce the amount of non-nutritive sucking, suggesting that the consumption of milk...

  9. Some aspects of milk that elicit non-nutritive sucking in the calf

    Contributor(s):: Passille, A. M. de, Rushen, J., Janzen, M.

    Male Holstein dairy calves were allowed to suck a non-nutritive teat after meals of either cow milk or milk replacer, and the amount of non-nutritive sucking that occurred during the 10 min following the meal was observed. There were no differences between milk and commercial milk replacer in the...

  10. Stereotyped pecking after feeding by restricted-fed fowls is influenced by meal size

    Contributor(s):: Savory, C. J., Mann, J. S.

    Growing broiler breeder chickens, fed routinely according to a programme of chronic food restriction, typically show increased pacing before feeding time and increased drinking and pecking at non-food objects afterwards. Expression of this behaviour is often stereotyped in form. In 2 experiments...

  11. Stimulation of serotonin (5-HT) activity reduces spontaneous stereotypies in female but not in male bank voles ( Clethrionomys glareolus ). Stereotyping female voles as a new animal model for human anxiety and mood disorders?

    Contributor(s):: Schoenecker, B., Heller, K. E.

    Spontaneously stereotyping female and male bank voles were injected daily (except on days assigned for monitoring behaviour) during 3 weeks with placebo, the neurolepticum clozapine or the SSRI antidepressant citalopram. Clozapine blocks dopamine (DA) receptors and acts as a partial serotonin...

  12. Development of stereotypies and polydipsia in wild caught bank voles ( Clethrionomys glareolus ) and their laboratory-bred offspring. Is polydipsia a symptom of diabetes mellitus?

    Contributor(s):: Schoenecker, B., Heller, K. E., Freimanis, T.

    The development of stereotypies and polydipsia was studied in wild caught bank voles (P: n=92) and their laboratory-bred offspring (F1: n=248). All animals were kept isolated in barren cages in the laboratory. In the P generation, no individuals developed stereotypies, but 22% developed...

  13. Stereotypies in heifers are affected by feeding regime

    Contributor(s):: Redbo, I., Nordblad, A.

    The effect of giving different types of food which result in long or short feeding durations on stereotypy levels was studied. Forty-eight tethered heifers of the Swedish Red and White Breed, with an average age of 16 months, were subjected to the same treatment. During the first 2 weeks of the...

  14. Behavioural and physiological responses of horses to initial training: the comparison between pastured versus stalled horses

    Contributor(s):: Rivera, E., Benjamin, S., Nielsen, B., Shelle, J., Zanella, A. J.

    Horses kept in stalls are deprived of opportunities for social interactions, and the performance of natural behaviour is limited. Inadequate environmental conditions may compromise behavioural development. Initial training is a complex process and it is likely that the responses of horses may be...

  15. Indication of a genetic basis of stereotypies in laboratory-bred bank voles ( Clethrionomys glareolus )

    Contributor(s):: Schoenecker, B., Heller, K. E.

    The development of stereotypies was studied in 2 successive laboratory-bred generations of bank voles representing F1 (n=248) and F2 (n=270) of an originally wild caught stock. It was shown that the propensity to develop stereotypies under barren housing conditions strongly relates to the same...

  16. 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...

  17. Differences in background and outcome of three behavior problems of dogs

    Contributor(s):: Takeuchi, Y., Ogata, N., Houpt, K. A., Scarlett, J. M.

    In order to characterize the three major behaviour problems, aggression toward owners, aggression toward strangers and separation anxiety, backgrounds of dogs and general outcomes of the behavioural treatments were analyzed retrospectively. There were 169 cases of aggression toward owners, 84...

  18. 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...

  19. 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...
