  1. 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...

  2. 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...

  3. 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...

  4. 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...

  5. 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...

  6. 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...

  7. 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...

  8. 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...

  9. 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...

  10. 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...

  11. Early rearing interacts with temperament and housing to influence the risk for motor stereotypy in rhesus monkeys ( Macaca mulatta )

    Contributor(s):: Vandeleest, J. J., McCowan, B., Capitanio, J. P.

    Laboratory and zoo housed non-human primates sometimes exhibit abnormal behaviors that are thought to reflect reduced well-being. Previous research attempted to identify risk factors to aid in the prevention and treatment of these behaviors, and focused on demographic (e.g. sex or age) and...

  12. 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...

  13. 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...

  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. Mental health of dogs formerly used as 'breeding stock' in commercial breeding establishments

    Contributor(s):: McMillan, F. D., Duffy, D. L., Serpell, J. A.

    Canine commercial breeding establishments (CBEs) are kennel facilities where puppies are produced in large numbers for commercial sale. In the popular media, CBEs are commonly referred to as "puppy mills" or "puppy farms." Conditions in CBEs vary widely in quality. Dogs in these facilities are...

  16. 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...

  17. Feeding motivation and stereotypies in pregnant sows fed increasing levels of fibre and/or food

    Contributor(s):: Bergeron, R., Bolduc, J., Ramonet, Y., Meunier-Salaun, M. C., Robert, S.

    Twenty-one multiparous sows were used in a Latin square design, from days 7 to 90 of gestation, to test the effect of fibre and feed levels on feeding motivation and feeding-related stereotypies. Treatments were: VHF (very high-fibre, 29% ADF, 50% NDF, 4.5 kg/day); HF (high-fibre, 23% ADF, 43%...

  18. 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...

  19. Buller steer syndrome review

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