  1. Classifying the severity of scientific animal use: a review of international systems

    Contributor(s):: Fenwick, N., Ormandy, E., Gauthier, C., Griffin, G.

    Severity classification systems (ie pain scales, categories of invasiveness, degrees of severity etc) are used to classify the adverse effects experienced by animals used for scientific purposes. Currently, eleven countries use severity classification systems. These systems have developed in...

  2. Consciousness, cognition and animal welfare. Proceedings of the UFAW symposium, Zoological Society of London's meeting rooms, London, UK, 11-12 May, 2000

    This supplement consists of abstracts and articles presented during the symposium. Topics presented focused on the consciousness, cognition and animal welfare.

  3. Consequences of enhancing environmental complexity for laboratory rodents - a review with emphasis on the rat

    Contributor(s):: Sorensen, D. B., Ottesen, J. L., Hansen, A. K.

    Enhancing the complexity of the environments of captive animals is often referred to as environmental enrichment, and aims to have positive effects on the animals' well-being. Such enrichments may have consequences both for so-called 'normal' behaviour and for the pathophysiology of the animals...

  4. Control and complexity in novel object enrichment

    Contributor(s):: Sambrook, T. D., Buchanan-Smith, H. M.

  5. Deflighting procedures and their welfare implications in captive birds

    Contributor(s):: Hesterman, H., Gregory, N. G., Boardman, W. S. J.

    Deflighting is used to prevent large captive birds from escaping by limiting their ability to fly. This practice deprives birds of this normal behaviour, but can allow them to express other behaviours that would be suppressed if they were confined to cages or aviaries. The potential negative...

  6. Effective feeding enrichment for non-human primates: a brief review

    Contributor(s):: Reinhardt, V., Roberts, A.

    This review summarizes the feeding enrichment options that have been shown to promote more foraging and feed processing activities while ameliorating behavioural pathologies in captive non-human primates.

  7. Effects of lighting on the welfare of domestic poultry: a review

    Contributor(s):: Manser, C. E.

    Four aspects of lighting which may affect the behaviour and physiology of housed poultry are light intensity, photoperiod, light source and wavelength. These factors are frequently manipulated in an attempt to improve productivity and to facilitate management practices. This review examines the...

  8. Enriching the lives of zoo animals, and their welfare: where research can be fundamental

    Contributor(s):: Robinson, M. H.

  9. Enrichment of laboratory caging for rats: a review

    Contributor(s):: Patterson-Kane, E. G.

    Rats are well-understood and widely used laboratory species that should be provided with environmentally enriched caging in line with modern animal welfare guidelines. This paper reviews which sources of enrichment are effective and should be prioritized, and how methods for providing enrichment...

  10. Evaluation of welfare indicators for the social environment in cattle herds

    Contributor(s):: Johannesson, T., Sorensen, J. T.

    The social environment is very important for the welfare of animals in loose housing dairy production systems. This article reviews recent literature on the effect of animal density (AD) and regrouping (RG) on the welfare of cattle and describes the development of feasible indicators for the...

  11. Factors influencing human attitudes to animals and their welfare

    Contributor(s):: Serpell, J. A.

    This paper reviews the literature on human attitudes to animals, and postulates the existence of two primary motivational determinants of attitudes labelled 'affect' and 'utility'. It also proposes that the relative strengths of these key attitude dimensions are affected by various modifying...

  12. Feed additives: do they add to animal welfare? An evaluation

    Contributor(s):: Kan, C. J., Jager, L. P., Grommers, F. J.

    This paper attempts to draw attention to the use of growth-promoting and disease-preventing feed additives and their possible adverse effects on animal welfare, where effects on the self-regulating capacities of the animals are used as yardsticks of animal welfare. First, the groups, the use and...

  13. Genetic selection for poultry behaviour: big bad wolf or friend in need?

    Contributor(s):: Jones, R. B., Hocking, P. M.

    This paper reviews selective breeding studies in which underlying fearfulness, sociality, feather pecking, adrenocortical responsiveness and growth rate were manipulated in Japanese quail and fowls. The apparent benefits of selection for these traits are discussed, as are the ethical issues...

  14. How has the risk of predation shaped the behavioural responses of sheep to fear and distress?

    Contributor(s):: Dwyer, C. M.

    To use behaviours as indicators of stress it is important to understand their underlying causation. For a prey animal in the wild, such as a sheep, behavioural responses have evolved to evade detection and capture by predators. The behavioural responses of the wild ancestors of domestic sheep to...

  15. Individual differences in temperament of domestic animals: a review of methodology

    Contributor(s):: Manteca, X., Deag, J. M.

  16. Mammal trapping: a review of animal welfare standards of killing and restraining traps

    Contributor(s):: Iossa, G., Soulsbury, C. D., Harris, S.

    Millions of wild mammals are trapped annually for fur, pest control and wildlife management. Ensuring the welfare of trapped individuals can only be achieved by trapping methods that meet accepted standards of animal welfare. At the international level, the assessment of mechanical properties of...

  17. Measures of developmental instability as integrated, A Posteriori indicators of farm animal welfare: a review

    Contributor(s):: Tuyttens, F. A. M.

    Developmental instability, of which fluctuating asymmetry is the most commonly used and recommended measure, has recently been claimed to be an objective, integrated and retrospective indicator of animal welfare. The theoretical and empirical grounds for these claims are reviewed. In theory,...

  18. Operant animal welfare: productive approaches and persistent difficulties

    Contributor(s):: Patterson-Kane, E. G., Pittman, M., Pajor, E. A.

    Operant procedures occupy a prominent role within animal welfare science because they provide information about the strength of animals' preferences. It is assumed that strongly motivated choices commonly indicate conditions necessary for uncompromised welfare. A review of the literature shows...

  19. Pain in birds

    Contributor(s):: Gentle, M. J.

    The physiology of pain, pain receptors, behavioural and physiological responses to pain, pain following trauma (including beak amputation), and analgesia in birds are reviewed.

  20. Painful dilemmas: the ethics of animal-based pain research

    Contributor(s):: Magalhaes-Sant'Ana, M., Sandoe, P., Olsson, I. A. S.

    While it has the potential to deliver important human benefits, animal-based pain research raises ethical questions, because it involves inducing pain in sentient beings. Ethical decision-making, connected with this variety of research, requires informed harm-benefit analysis, and the aim of this...
