  1. Increased reproductive output in stereotypic captive Rhabdomys females: potential implications for captive breeding

    Contributor(s):: Jones, M. A., Lierop, M. van, Mason, G., Pillay, N.

    Captive animal populations can diverge considerably from populations in the wild, despite the animals not being deliberately domesticated. If the phenotypes which are of benefit in captivity are heritable, the genotypes of captive-stock can diverge swiftly and substantially from wild-stock. Using...

  2. 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...

  3. Intersucking in dairy cattle - review and questionnaire. (Special Issue: Behaviour and welfare of cattle)

    Contributor(s):: Lidfors, L., Isberg, L.

    Intersucking is an abnormal behaviour in dairy heifers and cows, and it is defined by one animal sucking the teat of another animal with the intention of sucking milk. The aim of this paper is to review earlier studies on intersucking in dairy cattle and to present results from a questionnaire...

  4. ISAE international congresses, 1999-2001. (International Society for Applied Ethology Special Issue)

    Contributor(s):: Widowski, T., Mench, J.

    This special issue of Applied Animal Behaviour Science contains topics on the International Society for Applied Ethology (ISAE) congress. The 8 topics include (1) human-animal interactions in livestock production; (2) applied and basic research in farm animal welfare; (3) transferring the results...

  5. 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...

  6. 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...

  7. Owner attitudes and dog behaviour problems

    Contributor(s):: O'Farrell, V.

    In the treatment of dog behaviour problems, assessment of the owner's attitude is usually an essential part of the diagnostic process. Questionnaire studies of groups of owners reveal wide variation in both degree and kind of owner attachment. Individual-centred methods such as the Kelly...

  8. 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...

  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. 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...

  12. 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...

  13. 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...

  14. 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...

  15. 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...

  16. 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...

  17. 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...

  18. 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...

  19. Treatment of separation anxiety in dogs with clomipramine: results from a prospective, randomized, double-blind, placebo-controlled, parallel-group, multicenter clinical trial

    Contributor(s):: King, J. N., Simpson, B. S., Overall, K. L., Appleby, D., Pageat, P., Ross, C., Chaurand, J. P., Heath, S., Beata, C., Weiss, A. B., Muller, G., Paris, T., Bataille, B. G., Parker, J., Petit, S., Wren, J.

    The efficacy and tolerability of clomipramine in the treatment of separation anxiety in dogs was tested in a prospective, randomized, double-blind, placebo-controlled, parallel-group, international multicentre clinical trial. For a diagnosis of separation anxiety, dogs had to exhibit at least one...
