  1. 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...

  2. Applied animal behaviour science. (Special issue: Suckling)

    Contributor(s):: Lidfors, L., Svennersten-Sjaunja, K., Redbo, I.

    This supplement contains articles that focus on behavioural and physiological aspects of suckling and/or sucking in ruminants. Abnormal sucking behaviour, particularly cross-sucking and non-nutritive sucking, in calves are presented; and the effects of milk flow and milk volume, the presence of a...

  3. Do the stereotypies of pigs, chickens and mink reflect adaptive species differences in the control of foraging?

    Contributor(s):: Mason, G., Mendl, M.

    Species differences in food-related stereotypies and natural foraging behaviour are discussed, and evolutionary explanations for these species differences, and reasons why apparent species differences in stereotypy may be artefacts of husbandry are postulated.

  4. Geophagia in horses: a short note on 13 cases

    Contributor(s):: McGreevy, P. D., Hawson, L. A., Habermann, T. C., Cattle, S. R.

    Recorded in several species including humans, geophagia or soil eating has been observed in both wild and domesticated horses and has generally been regarded as an indication of nutritional deficiency or "boredom". Studies of soils consumed by different species have led to several theories as to...

  5. Behaviour patterns and time course of activity in dogs with separation problems

    Contributor(s):: Lund, J. D., Jorgensen, M. C.

    An analysis of video-recordings of 20 dogs with separation problems suggested that separation behaviour may be divided into; exploratory behaviour, object play including elements of predatory behaviour, destructive behaviour and vocalization. Elimination behaviour was only found in one case....

  6. Feather eating in layer pullets and its possible role in the aetiology of feather pecking damage

    Contributor(s):: McKeegan, D. E. F., Savory, C. J.

    Feather eating and its possible relationship with damaging pecking was examined in 144 pen-housed ISA Brown layer pullets. Collection and measurement of loose feathers in sample plots on 12 pen floors (feather were characterized as 'short' or 'long'), and examination of faecal droppings (eaten...

  7. 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...

  8. 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.

  9. 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...

  10. A case control study of on-farm risk factors for tail biting in pigs

    Contributor(s):: Moinard, C., Mendl, M., Nicol, C. J., Green, L. E.

  11. 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...

  12. 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...

  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. 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...

  15. Cross-sucking by dairy calves may become a habit or reflect characteristics of individual calves more than milk allowance or weaning

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

    To examine the effects of milk allowance and weaning age on cross-sucking, 45 dairy calves were housed in groups of nine and fed milk and grain-based starter feed from automated feeders and allocated to three treatment groups: (A) Low-Milk Early-Weaned (fed 6 L/d of milk until weaned at 47 d of...

  16. 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...

  17. 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...

  18. 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...

  19. 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)...

  20. 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...
