  1. Light, vision and the welfare of poultry

    Contributor(s):: Prescott, N. B., Wathes, C. M., Jarvis, J. R.

    The visual system of domestic poultry evolved in natural light environments, which differ in many respects from the artificial light provided in poultry houses. Current lighting systems are designed mainly around human vision and poultry production, ignoring the requirements of poultry vision and...

  2. Mealworm dispensers as environmental enrichment for captive Rodrigues fruit bats ( Pteropus rodricensis )

    Contributor(s):: O'Connor, K. I.

    This study is an assessment of the use of mealworm dispensers as environmental enrichment devices for Rodrigues fruit bats (Pteropus rodricensis). Captive animals frequently receive easily consumed food at set times and locations, which often minimizes the time they spend searching for and...

  3. Methods for measuring feeding motivation in sheep

    Contributor(s):: Jackson, R. E., Waran, N. K., Cockram, M. S.

    An operant crate and a push-door were used to measure feeding motivation in Suffolk sheep (2-4 years of age) after 0, 6, 12, 18 and 24 h without feed. In experiment 1 (n=12), sheep had to push a panel with their noses to obtain a feed reward. In experiment 2 (n=14), sheep had to run a race and...

  4. Preference of domestic rabbits for grass or coarse mix feeds

    Contributor(s):: Leslie, T. K., Dalton, L., Phillips, C. J. C.

    The motivation of juvenile rabbits to graze was tested by offering a choice of coarse mix or grass as rewards to rabbits fed a nutritionally adequate diet of carrots and hay. Before measuring the motivation of the 16 rabbits, eight were offered access to grass for 16 days and the remaining eight...

  5. Rapid behavioural adjustments to unfavourable light conditions in European starlings ( Sturnus vulgaris )

    Contributor(s):: Maddocks, S. A., Bennett, A. T. D., Cuthill, I. C.

  6. Reducing post-mixing aggression and skin lesions in weaned pigs by application of a synthetic maternal pheromone

    Contributor(s):: Guy, J. H., Burns, S. E., Barker, J. M., Edwards, S. A.

    In commercial pig production, piglets are often mixed after weaning which can result in severe aggression and lead to body damage, disruption of feeding behaviour and reduced growth. This experiment investigated whether application of a synthetic maternal pheromone to groups of weaned pigs in...

  7. Relationship between rooting behaviour and foraging in growing pigs

    Contributor(s):: Beattie, V. E., O'Connell, N. E.

    The objective of the present study was to investigate the relationship between rooting behaviour and foraging in growing pigs. In study 1, forty-eight 11-week-old pigs were housed in eight groups of six with access to a rooting substrate in the form of spent mushroom compost. In half of the...

  8. Responses to short-term exposure to simulated rain and wind by dairy cattle: time budgets, shelter use, body temperature and feed intake

    Contributor(s):: Schutz, K. E., Clark, K. V., Cox, N. R., Matthews, L. R., Tucker, C. B.

    Our objective was to examine how short-term exposure to wind or rain, or the combination of wind and rain, influences behavioural and physiological responses and the motivation for shelter. Twenty-four, non-lactating, pregnant Holstein-Friesian cows were individually housed and allocated one of...

  9. Rope test may indicate efficacy of tail-biting treatments in growing pigs

    Contributor(s):: Bracke, M. B. M.

    Tail biting is a most serious welfare problem in pigs raised for slaughter. In instances of an outbreak of tail biting, scientists have recommended that farmers take measures such as removal of affected animals, provision of enrichment materials and application of repellents to the pigs' tails....

  10. The effect of a moving bait on the behaviour of captive cheetahs ( Acinonyx jubatus )

    Contributor(s):: Williams, B. G., Waran, N. K., Carruthers, J., Young, R. J.

  11. The effect of feeding a high fibre diet on the welfare of sows housed in large dynamic groups

    Contributor(s):: Stewart, C. L., Boyle, L. A., McCann, M. E. E., O'Connell, N. E.

    This study assessed the effect of increasing fibre levels in the concentrate ration on the welfare of sows housed in a large dynamic group. One hundred and twelve Large White x Landrace sows were allocated to one of two treatments over six replicates. Treatments were as follows: (i) High Fibre...

  12. The effect of increasing dietary fibre on feeding, rumination and oral stereotypies in captive giraffes ( Giraffa camelopardalis )

    Contributor(s):: Baxter, E., Plowman, A. B.

    Many captive giraffes perform oral stereotypes, in particular tongue-playing, licking of objects (including conspecifics) and vacuum chewing. Typically, the diet of these large ruminants in captivity consists mostly of food concentrates, which are consumed rapidly and do not provide stimulation...

  13. The effectiveness of environmental enrichment on reducing stereotypic behaviour in two captive vicugna ( Vicugna vicugna )

    Contributor(s):: Parker, M., Goodwin, D., Redhead, E., Mitchell, H.

    Environmental enrichment by increasing foraging behaviour and providing food item choice are widely practised and generally accepted as effective methods for reducing stereotypic behaviour in captive animals. In this study, the effectiveness of increasing foraging patch choice and food item...

  14. The effects of different types of feeding enhancements on the behaviour of single-caged, yearling rhesus macaques

    Contributor(s):: Schapiro, S. J., Suarez, S. A., Porter, L. M., Bloomsmith, M. A.

    Captive primates rarely spend as much time searching for, obtaining and processing feed as do their wild counterparts. Enrichment techniques designed to encourage captive primates to spend more species-appropriate amounts of time in foraging behaviour have been successful. Behavioural effects of...

  15. Do pets influence the quantity and choice of food offered to them by their owners: lessons from other animals and the pre-verbal human infant?

    Contributor(s):: Day, J. E. L., Kergoat, S., Kotrschal, K.

    All social animals influence each other's behaviour. One area of particular interest is the social interaction that occurs between pets and their owners. Within pet-owner dyads, food and feeding are always part of the dyadic ritual. In this review, we hypothesize that feeding can be considered to...

  16. 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.

  17. Behaviour of cats

    Contributor(s):: Bradshaw, J.

    The origin, history and effects of domestication, behaviour and relationship with humans of cats are described.

  18. Welfare implications of dairy calf and heifer rearing

    Contributor(s):: Lawrence, A. B., Dwyer, C. M., Jarvis, S., Roberts, D.

    In this chapter we have focused primarily on behavioural issues that emerge from current practices of calf rearing. We have used the perspective of behavioural development and existing knowledge from other species to emphasise that early events in the calf's life (early weaning and individual...
