  1. Effect of housing density on growth, agonistic behaviour, and activity in hatchling saltwater crocodiles (Crocodylus porosus)

    Contributor(s):: Brien, Matthew L., Webb, Grahame J., McGuinness, Keith A., Christian, Keith A.

    The purpose of this study was to examine the effect of density on growth rate, agonistic behaviour, activity and use of space by hatchling C. porosus in captivity. Hatchling C. porosus were raised in identical enclosures (1.5m2) at different densities (3.3, 6.7, 13.3 and 20.0hatchlings/m2; or...

  2. Effects of space allowance and simulated sea transport motion on behavioural and physiological responses of sheep

    Contributor(s):: Navarro, Grisel, Col, Ramazan, Phillips, Clive J. C.

    Transporting sheep by sea exposes them to some prolonged floor motions, and their responses may depend on their space allowance. We simulated sea motion in a crate with a moveable and programmable floor, to measure behaviour and physiological responses. Nine sheep were exposed in groups of 3 for...

  3. Tail posture as a detector of tail damage and an early detector of tail biting in finishing pigs

    Contributor(s):: Larsen, Mona Lilian Vestbjerg, Andersen, Heidi Mai-Lis, Pedersen, Lene Juul

    The purpose of the current study was to investigate the relation between the tail posture of finishing pigs and tail damage with the aims to use tail posture as (1) a detector of tail damage, (2) an early detector of tail biting to possibly predict and prevent bleeding tail damage. Tails of each...

  4. Exploration Feeding and Higher Space Allocation Improve Welfare of Growing-Finishing Pigs

    Contributor(s):: Herman M Vermeer, Nienke CPMM Dirx-Kuijken, Marc BM Bracke

    Lack of environmental enrichment and high stocking densities in growing-finishing pigs can lead to adverse social behaviors directed to pen mates, resulting in skin lesions, lameness, and tail biting. The objective of the study was to improve animal welfare and prevent biting behavior in an...

  5. Toward an understanding of beaver management as human and beaver densities increase

    Contributor(s):: Siemer, William F., Jonker, Sandra A., Decker, Daniel J., Organ, John F.

  6. Stocking density affects welfare indicators of growing pigs of different group sizes after regrouping

    Contributor(s):: Fu, Lingling, Li, Huizhi, Liang, Tingting, Zhou, Bo, Chu, Qingpo, Schinckel, Allan P., Yang, Xiaojing, Zhao, Ruqian, Li, Pinghua, Huang, Ruihua

    In recent years, the concept of animal welfare began to be accepted by the Chinese people. On some intensive pig farms, the stocking density for growing pigs is too great, leading to decreased animal welfare. In order to study the relationships between stocking density and welfare indicators and...

  7. On-farm evaluation of the Salmon Welfare Index Model (SWIM 1.0): theoretical and practical considerations

    Contributor(s):: Folkedal, O., Pettersen, J. M., Bracke, M., Stien, L. H., Nilsson, J., Martins, C., Breck, O., Midtlyng, P. J., Kristiansen, T.

    The present study investigated the operational feasibility of the recently developed Salmon Welfare Index Model (SWIM 1.0) designed for Atlantic salmon ( Salmo salar L) in production cages. Ten salmon farms containing spring smolts were visited twice, first between May and June the first year in...

  8. The contribution of broiler chicken welfare certification at farm level to enhancing overall animal welfare: the case of Brazil

    Contributor(s):: Souza, A. P. O., Molento, C. F. M.

    The intensification of farm animal welfare debate has led to an increasing number of certification schemes covering this issue; however, there are concerns about the contribution of these schemes in improving welfare. The aims of this study were to identify certification schemes for broiler...

  9. Agonistic behaviour, skin lesions and activity pattern of entire male, female and castrated male finishing pigs

    Contributor(s):: Bunger, B., Schrader, L., Schrade, H., Zacharias, B.

    Fattening of intact boars is the least invasive alternative to the detrimental welfare effects of surgical castration of piglets. However, beside problems such as boar taint the divergent agonistic and sexual behaviour of boars may impair the pigs' welfare during fattening. To evaluate the effect...

  10. Effects of under- and overstocking freestalls on dairy cattle behaviour

    Contributor(s):: Winckler, C., Tucker, C. B., Weary, D. M.

    Freestall availability affects cattle behaviour and most studies in this area have focused on overstocking. We studied the effects of three levels of stall availability, including both over- and understocking on the time budgets and agonistic interactions in 36 dairy cattle in four stable groups....

  11. The ethics of a co-regulatory model for farm animal welfare research

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

    Standards for farm animal welfare are variously managed at a national level by government-led regulatory control, by consumer-led welfare economics and co-regulated control in a partnership between industry and government. In the latter case the control of research to support animal welfare...

  12. Stakeholder attitudes toward farm animal welfare

    Contributor(s):: Heleski, C. R., Mertig, A. G., Zanella, A. J.

    We developed a survey to measure attitudes toward farm animal welfare, then targeted two US groups considered highly influential in this area: veterinary college faculty members with large animal/food animal emphasis (VCF) and animal science faculty members (ANS). The survey was conducted via...

  13. Ranging characteristics of the domestic cat ( Felis catus) in an urban environment

    Contributor(s):: Thomas, R. L., Baker, P. J., Fellowes, M. D. E.

    In many countries, high densities of domestic cats ( Felis catus) are found in urban habitats where they have the potential to exert considerable predation pressure on their prey. However, little is known of the ranging behaviour of cats in the UK. Twenty cats in suburban Reading, UK, were fitted...

  14. Influence of stocking density on tonic immobility, lameness, and tibial dyschondroplasia in broilers

    Contributor(s):: Sanotra, G. S., Lawson, L. G., Vestergaard, K. S.

    This study assessed the effect of stocking density on the development of fear reaction (tonic immobility), lameness (gait), and tibial dyschondroplasia in broiler chicks of mixed sex. During 3 experiments, the study used 49 500 broiler chicks (Ross 208). Of these, 432 focal chicks were randomly...

  15. 'Bling with bite' - the rise of status and weapon dogs

    Contributor(s):: Harding, S.

  16. Motivation for group housing in gestating sows

    Contributor(s):: Kirkden, R. D., Pajor, E. A.

  17. The effect of group size and stocking density on the welfare and performance of hens housed in furnished cages during summer

    Contributor(s):: Guo, Y. Y., Song, Z. G., Jiao, H. C., Song, Q. Q., Lin, H.

  18. The effect of housing system on the behaviour and growth parameters of fattening rabbits

    Contributor(s):: Moinard, C., Mendl, M., Nicol, C. J., Green, L. E.

  20. Agonistic behaviour and feather pecking in single-sexed and mixed groups of laying hens

    Contributor(s):: Oden, K., Vestergaard, K. S., Algers, B.

    The effects of the presence of males on female aggressiveness and feather pecking in groups of about 500 laying hens housed in an aviary system were studied. In all, 10 groups of ISA Brown laying hens were observed at 21, 35, 45 and 55 weeks of age on 2 farms, during 2 years. In the second year,...
