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...
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...
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...
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...
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...
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...
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...
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...
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...
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...

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
Dietary tryptophan supplementation in privately owned mildly anxious dogs
Contributor(s):: Bosch, G., Beerda, B., Beynen, A. C., van der Borg, J. A. M., van der Poel, A. F. B., Hendriks, W. H.
Food composition has been reported to influence mood and behaviour in humans and animals and it could help to reduce unwanted behaviour in dogs. Anxiety-related behaviour is associated with the functioning of the central serotonergic system and here it was investigated if dietary supplementation...
Effects of early weaning and housing conditions on the development of stereotypies in farmed mink
Contributor(s):: Jeppesen, L. L., Heller, K. E., Dalsgaard, T.
141 female mink pups were weaned at 6, 8 or 10 weeks of age and subjected to two different housing conditions. They were either kept together with a single male sibling in traditional mink cages (30 x 45 x 90 cm) or housed socially with all litter-mates in an alternative system consisting of...
Factors affecting pica in the domestic cat
Contributor(s):: Bradshaw, J. W. S., Neville, P. F., Sawyer, D.
A postal survey was conducted of the owners of 152 cats, mainly of oriental breeds, which exhibited pica (defined broadly, as chewing, sucking or ingesting non-nutritive materials). The most common material was wool (93% of cases), followed by cotton, man-made fabrics, rubber/plastic and...
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%...
Genetics and genomics of animal behaviour and welfare - challenges and possibilities. (Special Issue: Farm animal welfare since the Brambell report.)
Contributor(s):: Jensen, P., Buitenhuis, B., Kjaer, J., Zanella, A., Mormede, P., Pizzari, T.
Traditionally, the contribution of applied ethology to animal welfare science has concentrated on understanding the reactions of animals to their housing conditions. Domestication has had small effects on fundamental aspects of animal behaviour, and therefore, the needs of present day...
Housing conditions and behavioural problems of indoor cats as assessed by their owners
Contributor(s):: Heidenberger, E.
Housing conditions and behavioural problems of a sample of 1177 cats were described by their 550 owners. Indications for inadequate housing in the light of species-specific needs were analysed. 65.1% of the cats were Domestic European Shorthairs and 78.7% were castrated animals. 87% of the...
Inter-group variation in abnormal behaviour in chimpanzees ( Pan troglodytes ) and rhesus macaques ( Macaca mulatta )
Contributor(s):: Hook, M. A., Lambeth, S. P., Perlman, J. E., Stavisky, R., Bloomsmith, M. A., Schapiro, S. J.
The present study was designed to explore whether abnormal behaviour patterns in captive chimpanzees and rhesus macaques can provide additional data relevant to the question of social transmission of behaviour in non-human primates. The degrees to which various abnormal behaviours were displayed...
Measuring aggressiveness in growing pigs in a resident-intruder situation
Contributor(s):: Erhard, H. W., Mendl, M.
218 pigs of both sexes from 23 litters aged 7 or 11 weeks were used to examine aggressiveness in growing pigs. Individual pigs were isolated in one half of their home pen and an intruder pig was introduced. This pig was 2 to 3 weeks younger than the resident pig. The time from the first contact...
