Resources (81-100 of 100)

  1. Eliminatory behaviour of domestic dogs in an urban environment

    Contributor(s):: Reid, J. B., Chantrey, D. F., Davie, C.

  2. Social dominance of female dairy goats influences the dynamics of gastrointestinal parasite eggs

    | Contributor(s):: Ungerfeld, R., Correa, O.

    In ruminants, social hierarchies determine an unequal access to resources, such as food consumption, individuals from the other gender, or shade. Related to this, physiological status is associated with the social rank, resulting in differences in reproductive success, milk yield, or health...

  3. Influence of weaning age and an experimental Haemonchus contortus infection on behaviour and growth rates of lambs

    | Contributor(s):: Schichowski, C., Moors, E., Gauly, M.

    Four groups of 20 lambs each, differing in weaning age (6 or 13 weeks) and infection with Haemonchus contortus (infection after weaning or simultaneous to weaning), were observed and compared regarding the behaviour before, during and after these procedures. Furthermore the influence on...

  4. Behavioural responses of cattle to the odours of blood and urine from conspecifics and to the odour of faeces from carnivores

    | Contributor(s):: Terlouw, E. M. C., Boissy, A., Blinet, P.

    Before experimentation, 12 heifers were trained during 15 days to walk through a corridor for food. In the middle of the corridor, at either side, 2 ventilating odour dispensers were fixed behind perforated screens. The odours of urine from non-stressed and stressed conspecifics and of blood were...

  5. The maintenance behaviour and cleanliness of pigs in two-tier weaner decks

    | Contributor(s):: Lewis, N. J., Christison, G. I.

    Tiered weaner decks for pigs appear to have a major disadvantage because the faeces and urine from the pigs in the top pens drop through to the pigs in the lower pens. This may affect the well-being of these pigs and may cause the development of poor dunging habits. To determine the general...

  6. Detecting and neutralizing odor sources in dog and cat elimination problems

    | Contributor(s):: Melese, P.

  7. Height to withers and abdominal circumference effects on diets of grazing goats

    | Contributor(s):: Mellado, M., Rodriguez, A., Villarreal, J. A., Lopez, R.

    Diet selection in an arid rangeland of northern Mexico by short (height to withers 77 cm) multiparous non-pregnant, non-lactating does and the diets of multiparous non-pregnant, non-lactating does with reduced (101 cm) abdominal circumference is described from microhistological analysis of fecal...

  8. Discrimination between conspecific odour samples in the horse ( Equus caballus )

    | Contributor(s):: Hothersall, B., Harris, P., Sortoft, L., Nicol, C. J.

    Behavioural observations suggest that smell is important in social discriminations between horses but balanced studies of this capacity are lacking. We used a habituation-discrimination procedure to investigate the ability of horses to distinguish between pairs of odour samples from different...

  9. Relationships between behaviour and health in working horses, donkeys, and mules in developing countries

    | Contributor(s):: Burn, C. C., Dennison, T. L., Whay, H. R.

    Recent studies raise serious welfare concerns regarding the estimated 93.6 million horses, donkeys and mules in developing countries. Most equids are used for work in poor communities, and are commonly afflicted with wounds, poor body condition, respiratory diseases, parasites, dental problems,...

  10. Physiological and behavioural responses of laboratory rats housed at different tier levels and levels of visual contact with conspecifics and humans

    | Contributor(s):: Cloutier, S., Newberry, R. C.

    Laboratory rats are typically housed in clear or opaque cages on multi-tiered racks. Clear-walled cages allow a view of the room and facilitate visual social contact with neighbouring rats but may induce anxiety due to lack of visual cover. We hypothesized that degree of visibility of humans and...

  11. Faecal glucocorticoid level is not correlated with stereotypic pacing in two captive margays ( Leopardus wiedii )

    | Contributor(s):: Gusset, M.

    The 'coping hypothesis' of stereotypic behaviour - that stereotypies are performed as a means of helping the animal to cope with its environment by reducing stress - was tested using two adult female margays (Leopardus wiedii), an endangered neotropical small cat species. Within-individual and...

  12. Do double cages and access to occupational materials improve the welfare of farmed mink?

    | Contributor(s):: Hansen, S. W., Malmkvist, J., Palme, R., Damgaard, B. M.

    The effects of cage enrichments and additional space were studied in 60 pairs of mink kits kept in standard cages (STD) and 67 pairs of mink kits kept in enriched cages (ENR). During the period from mid July to the end of September both groups had alternate access to one and two connected cages....

  13. Time budgets and adrenocortical activity of cows milked in a robot or a milking parlour: interrelationships and influence of social rank

    | Contributor(s):: Lexer, D., Hagen, K., Palme, R., Troxler, J., Waiblinger, S.

    Adrenocortical activity and time budgets in a robotic milking system in two variants of cow traffic (partially forced, free) were compared with a conventional milking system, focusing on the relationships between adrenocortical activity, time budgets, and social rank of the cows. Both groups were...

  14. Modulation of aggression in male mice: influence of cage cleaning regime and scent marks

    | Contributor(s):: Loo, P. L. P. van, Kruitwagen, C. L. J. J., Zutphen, L. F. M. van, Koolhaas, J. M., Baumans, V.

    Group housing of male laboratory mice often leads to welfare problems due to aggressive behaviour. From a welfare perspective, individual housing is not a preferred solution to these problems - and so other ways of reducing aggression between male mice were sought. Aggression peaks after...

  15. Relationships between multiple welfare indicators measured in individual chickens across different time periods and environments

    | Contributor(s):: Nicol, C. J., Caplen, G., Edgar, J., Richards, G., Browne, W. J.

    The assessment of animal welfare requires the collection of multiple indicators of welfare but quantification of their associations in different contexts is lacking. Previous studies have examined correlations between a few indicators, but not relationships between many different indicators, or...

  16. A review of mulesing and other methods to control flystrike (cutaneous myiasis) in sheep

    | Contributor(s):: Phillips, C. J. C.

    Flystrike (cutaneous myiasis) in sheep has the potential to have a major impact on the welfare of significant numbers of sheep worldwide, but particularly in Australia. The main control method used in Australia, the mulesing operation to remove folds of skin from the hindquarters of the sheep, is...

  17. Cross-institutional assessment of stress responses in zoo animals using longitudinal monitoring of faecal corticoids and behaviour

    | Contributor(s):: Shepherdson, D. J., Carlstead, K. C., Wielebnowski, N.

    Cross-institutional studies that combine non-invasive physiological measures of stress responses and the assessment of individual differences in behaviour and temperament have great potential as tools for assessing the well-being of zoo animals and for identifying key environmental stimuli...

  18. Enriching the metabolic cage: effects on rat physiology and behaviour

    | Contributor(s):: Sorensen, D. B., Mortensen, K., Bertelsen, T., Vognbjerg, K.

    Metabolic cages are used for housing rats and mice for up to five days for collection of urine and/or faeces. The small, barren area of the metabolic cage compromises animal welfare as the animals lack a solid floor, shelter, nest material and social contact. We constructed and tested a...

  19. The husbandry, welfare and health of captive African civets ( Vivera civetica ) in western Ethiopa

    | Contributor(s):: Tolosa, T., Regassa, F.

    A study was carried out during the period from September 2001 to August 2002 in Jimma zone, western Ethiopia to evaluate the husbandry and health of captive African civets (Vivera civetica). Wild civets were found in the wild in all 13 of the districts in the zone, although traditional...

  20. Environmental enrichment for maned wolves ( Chrysocyon brachyurus ): group and individual effects

    | Contributor(s):: Vasconcellos, A. S., Guimaraes, M. A. B. V., Oliveira, C. A., Pizzutto, C. S., Ades, C.

    Procedures that increase foraging and exploratory behaviours are generally accepted as effective at improving welfare and reducing stereotypies in captive animals. To determine the effect of food and toy enrichment on the behaviour and hormonal levels of maned wolves (Chrysocyon brachyurus), 11...
