  1. Skin stimulated induction of mouth movements in cattle

    | Contributor(s):: Simonsen, H. B.

    Six animals in a free-ranging herd of 10 Aberdeen Angus cattle showed mouth movements induced by skin stimulation by grooming the sacro-coccygeal region with a horse grooming brush. Three of the animals reacted by mouth movements similar to stereotypic tongue rolling. 22 (37

  2. Stereotypic behaviour and tail biting in farmed mink (Mustela vison) in a new housing system

    | Contributor(s):: Vinke, C. M., Eenkhoorn, N. C., Netto, W. J., Fermont, P. C. J., Spruijt, B. M.

    Farmed mink are known for showing stereotypies and tail biting, behaviours that are mostly viewed as indicators of reduced welfare. Among the factors that are often described as being relevant for the welfare of mink are food management systems, age at weaning, and type/presence of nest boxes and...

  3. Strain-specific effects of cage enrichment in male laboratory mice (Mus musculus)

    | Contributor(s):: Nevison, C. M., Hurst, J. L., Barnard, C. J.

    Within-cage behaviour and physiological parameters were compared among male mice from 6 strains in an enriched (nesting material and a perspex tunnel) and non-enriched environment (n = 32 per strain). The outbred strains were more aggressive than the inbred strains and levels of aggression were...

  4. Stress and animal welfare

  5. Tail and ear biting lesions in pigs: an epidemiological study

    | Contributor(s):: Smulders, D., Hautekiet, V., Verbeke, G., Geers, R.

    Tail and ear biting lesions have a negative effect both on the animal welfare status of pigs (Sus scrofus) and the economical revenue of the pig farm. Tail biting behaviour is an unpredictable, abnormal behaviour that is thought to have a multifactorial origin. On-farm factors influencing tail...

  6. Tail-biting in mink (Mustela vison) is influenced by age at removal from the mother

    Full-text: Available

    | Contributor(s):: Mason, G.

    Previous studies have shown that male mink (Mustela vison) removed from their mothers at seven weeks of age develop more tail-biting than males left with their mothers until six months. Mink in the wild do not damage their own pelts in this way, and such behaviour may well be an indication of...

  7. The early ontogeny of bar-gnawing in laboratory gerbils

    | Contributor(s):: Wiedenmayer, C.

  8. The effect of a short-term biomedical research protocol on stereotyped rocking in young chimpanzees

    | Contributor(s):: Pazol, K. A., Bloomsmith, M. A.

  9. The effects of light intensity and light source on injuries due to pecking of male domestic turkeys (Meleagris gallopavo)

    | Contributor(s):: Moinard, C., Lewis, P. D., Perry, G. C., Sherwin, C. M.

    It has been shown that, in small groups of intact male domestic turkeys, supplementary ultraviolet (UV-A) radiation, visual barriers, and added straw (environmental enrichment) minimize the incidence of injurious pecking under incandescent light at 5 lux. This paper describes two experiments,...

  10. The welfare impact of increased gavaging doses in rats

    | Contributor(s):: Alban, L., Dahl, P. J., Hansen, A. K., Hejgaard, K. C., Jensen, A. L., Kragh, M., Thomsen, P., Steensgaard, P.

    Textbook recommendations for gavaging rats vary between 1-5 ml for an adult rat. Rats weighing either 130 or 250 g were gavaged with varying dosages of barium sulphate (BaSO4). After dosing, radiographs were taken at 0, 15 and 60 min. Animals showing a section of the small intestine totally...

  11. The welfare of farmed mink (Mustela vison) in relation to housing and management: a review

    | Contributor(s):: Nimon, A. J., Broom, D. M.

  12. Human and animal inter-relationships. Review Series: 3. Normal behaviour patterns of dogs: part I. 4. Behavioural problems of dogs: part II

    | Contributor(s):: Blackshaw, J. K.

    Most problems arise when the owner fails to realize that the dog must be part of a defined hierarchy. The treatment of aggression, attention seeking, and elimination, feeding and sexual problems is reviewed.

  13. Human and animal inter-relationships. Review Series: 6. Behavioural problems of cats: II

    | Contributor(s):: Blackshaw, J. K.

    | Contributor(s):: Ekesbo, I.

    This chapter covers horse domestication, changes in the animals and their environment, management, behaviour and welfare. Focus is given on innate or learned behaviour and different types of social behaviour. Some of the normal physiological frequency values of interest at clinical examination...
