Application of the TMS probe resulted in dominance of theta and delta waves and appearance of...

  6. Travel sickness and meat quality in pigs

    Contributor(s):: Bradshaw, R. H., Randall, J. M., Forsling, M. L., Rodway, R., Goode, J. A., Brown, S. N., Broom, D. M.

    An experiment was conducted to investigate the incidence of travel sickness in pigs, specific hormone concentrations at exsanguination and subsequent meat quality. Fifty, 80-kg slaughter pigs were transported on a lorry for 4.5 h. During the journey, behavioural observations of the individually...

  7. Use of conjoint analysis to weight welfare assessment measures for broiler chickens in UK husbandry systems

    Contributor(s):: Haslam, S. M., Kestin, S. C.

    For the purposes of farm animal welfare assessment, Farm Assurance Schemes and enforcement of animal welfare legislation, a requirement arises for a unitary welfare score which may be the amalgamation of several animal welfare measures. In amalgamating measures, weighting to reflect the...

  8. Using the Piglet Scream Test to enhance piglet survival on farms: data from outdoor sows

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

    The point of the Piglet Scream Test is to identify those sows that increase the survival of their piglets through good maternal behaviour. For this to work, sows must be shown to differ in their test responsiveness, for differences to be consistent across parities and for responsiveness to be...

  9. Validation of an Animal Needs Index for cattle using Test Theory

    Contributor(s):: Herva, T., Peltoniemi, O., Virtala, A. M.

    The validity of an ANI-based welfare index for cattle, the A-Index, was evaluated using Test Theory methods described for quality of life assessments in human medicine. Content validity was considered during the modification of the Index for Finnish beef production. In total, 43 items evaluating...

  10. Validation of broiler chicken gait scoring training in Thailand, Brazil and New Zealand

    Contributor(s):: Butterworth, A., Knowles, T. G., Whittington, P., Matthews, L., Rogers, A., Bagshaw, C. S.

    Broiler chickens are the most numerous terrestrial farmed animals on earth. These birds can suffer a range of pathologies which result in lameness, and one technique for assessing the impact of lameness on the individual bird, and on the flock has been gait scoring. This paper describes a study...

  11. Vocal-type classification as a tool to identify stress in piglets under on-farm conditions

    Contributor(s):: Borell, E. von, Bunger, B., Schmidt, T., Horn, T.

    Previous studies have shown that the analysis of high frequency stress calls in pigs can serve as a reliable tool in welfare research. Our study focuses on the classification of three different classes of piglet vocalisation: grunting, squealing and screaming. In a castration experiment...

  12. Welfare assessment in 82 pig farms: effect of animal age and floor type on behaviour and injuries in fattening pigs

    Contributor(s):: Courboulay, V., Eugene, A., Delarue, E.

    A welfare assessment method was built, based on criteria related to behaviour, lesion scores and human/animal interactions, and tested thereafter in two main types of farms differing by their type of floor: either concrete, fully or partially slatted (C; n=42) or straw bedding (S; n=40)....

  13. Welfare assessment of broilers through examination of haematomas, foot-pad dermatitis, scratches and breast blisters at processing

    Contributor(s):: Gouveia, K. G., Vaz-Pires, P., Costa, P. M. da

    Analysis of post mortem lesions is a common means for assessing poultry welfare during rearing and pre-slaughter handling. The aim of this study was to determine the influence of: age, sex, rearing system, total number of birds on-farm, period between catch and slaughter and distance from poultry...

  14. Welfare implications of nipple drinkers for broiler chickens

    Contributor(s):: Houldcroft, E., Smith, C., Mrowicki, R., Headland, L., Grieveson, S., Jones, T. A., Dawkins, M. S.

    Commercially reared broiler chickens are commonly supplied with drinking water through lines of nipple drinkers that are positioned above the birds' heads to avoid water leaking and spoiling the litter underfoot. This means that the birds have to peck upwards to obtain water, an action that is...

  15. Wire-floor pens as an alternative to metallic cages in fattening rabbits: influence on some welfare traits

    Contributor(s):: Martrenchar, A., Boilletot, E., Cotte, J. P., Morisse, J. P.

    The possibility of improving the welfare of fattening rabbits by rearing them in pens instead of cages was investigated. Time budgets, locomotion, ear lesions, breaking strength of the femur and productivity were compared in fattening rabbits kept at the same stocking density (15 rabbits m-2)...

  16. From "animal machines" to "happy meat"? Foucault's ideas of disciplinary and pastoral power applied to 'animal-centred' welfare discourse. (Special issue: Minding animals: Emerging issues concerning our relationships with other an

    Contributor(s):: Cole, M.

    Michel Foucault's work traces shifting techniques in the governance of humans, from the production of 'docile bodies' subjected to the knowledge formations of the human sciences (disciplinary power), to the facilitation of self-governing agents directed towards specified forms of self-knowledge...

  17. Silence and denial in everyday life - the case of animal suffering. (Special issue: Minding animals: Emerging issues concerning our relationships with other animals.)

    Contributor(s):: Wicks, D.

    How can we make sense of the fact that we live in a world where good people co-exist in silence about widespread animal suffering. How is it that sites of suffering such as laboratories, factory farms, abattoirs and animal transportation are all around us and yet we 'do not, in a certain sense,...

  18. Physical planning of intensive systems of beef cattle using systematic layout planning as an analytical tool and its relationship with animal well-being

    Contributor(s):: Guimaraes, M. C. C., Inoue, K. R. A., Bueno, M. M., Baeta, F. C., Tibirica, A. C. G., Tinoco, I. F. F.

    The intensification of animal production systems suggests that the future of production is not the increase of the herd, but the increase of productivity. The main goal of facility design is to provide space for a specific purpose, and to provide optimal conditions for its development;...
