  1. Evidence of competition for nest sites by laying hens in large furnished cages

    Contributor(s):: Hunniford, Michelle E., Torrey, Stephanie, Bédécarrats, Gregoy, Duncan, Ian J. H., Widowski, Tina M.

    Furnished cages are designed to accommodate behaviour considered important to laying hens, particularly nesting behaviour. Few researchers have studied the degree of competition for nest sites or the extent to which the amount of nest space affects nesting behaviour in large furnished cages. We...

  2. Astroturf as a dustbathing substrate for laying hens

    Contributor(s):: Alvino, Gina M., Tucker, Cassandra B., Archer, Gregory S., Mench, Joy A.

    Furnished cages for laying hens often contain an Astroturf (AT) pad which may be sprinkled with feed to promote foraging and dustbathing. We evaluated AT and AT plus feed (ATF) to determine if hens use these substrates for dustbathing. Hens (N=30) without prior exposure to substrate were housed...

  3. Behaviour and use of space in fattening rabbits as influenced by cage size and enrichment

    Contributor(s):: Buijs, Stephanie, Keeling, Linda J., Tuyttens, Frank A. M.

    In the few previous studies on the effects of space allowance on fattening rabbit behaviour, space allowance was confounded with group size. This is the first study of fattening rabbit behaviour in which space allowance was varied whilst group size was stable (8 animals per pen), although this...

  4. The inescapable problem of lab animal restraint | Garet Lahvis | TEDxMtHood

    Full-text: Available

    | Contributor(s):: Garet Lahvis

      Garet Lahvis is a pioneer in academic research on the mental experiences of laboratory mice and is an internationally recognized scientific expert on empathy. Using sophisticated behavioral experiments, his laboratory discovered that mice enjoy living with other mice and they can also...

  5. Laying hens’ preferences for nest surface type are affected by enclosure

    | Contributor(s):: Hunniford, M. E., Mason, G. J., Widowski, T. M.

    The nest surfaces preferred by hens are inconsistent with those typically provided in commercial settings. However, little research has explored hens’ preferences for commercially available nest surfaces. Our objective was to compare hens’ preferences for two such surfaces – red smooth and yellow...

  6. How tall should a mink cage be? Using animals’ preferences for different ceiling heights to improve cage design

    | Contributor(s):: Díez-León, María, Quinton, Margaret, Mason, Georgia

    Regulations and guidelines assume that taller cages are better for mink, because they permit more diverse postures (e.g. standing upright) and freedom to move. New Canadian Codes of Practice therefore stipulate cage ceiling heights of at least 38cm, while in Europe cages must be 46cm or taller....

  7. Nest alternatives: Adding a wire partition to the scratch area affects nest use and nesting behaviour of laying hens in furnished cages

    | Contributor(s):: Hunniford, Michelle E., Widowski, Tina M.

    Furnished cages (FC) are designed to accommodate highly motivated behaviour patterns like nesting; however, how hens perceive the resources provided in FCs is not fully understood. Our previous research of hens in FCs with a curtained nest (plastic mesh floor) and a scratch area (smooth plastic...

  8. Blue foxes’ (Vulpes lagopus) motivation to gain access and interact with various resources

    | Contributor(s):: Koistinen, Tarja, Korhonen, Hannu T., Hämäläinen, Elina, Mononen, Jaakko

    We analysed the willingness of blue foxes (Vulpes lagopus) to work for and utilise five resources: a platform, wooden block, sand floor, nest box and empty space. Ten juvenile blue fox males were housed singly in apparatus consisting of three cages connected with one-way doors through the walls...

  9. Keel impacts and associated behaviors in laying hens

    | Contributor(s):: Baker, Sydney L., Robison, Cara I., Karcher, Darrin M., Toscano, Michael J., Makagon, Maja M.

    Factors contributing to the development of keel bone damage are not well understood. This study aimed to identify behaviors and cage structures associated with acceleration events experienced by individual hens at their keels as the birds navigated their enriched colony cage environments....

  10. Cage size affects comfort, safety and the experienced security of working dogs in cars

    | Contributor(s):: Skånberg, Lena, Gauffin, Oskar, Norling, Yezica, Lindsjö, Johan, Keeling, Linda J.

    Working dogs often spend a large amount of their time in cars. It has been hypothesized that a larger compartment in the car would be more comfortable for the dog, but that a smaller space could be safer, especially while driving. This presents a potential conflict. In this study, working dogs of...

  11. Curtained nests facilitate settled nesting behaviour of laying hens in furnished cages

    | Contributor(s):: Hunniford, M. E., Widowski, T. M.

    Egg location can be used to determine the nests that hens prefer, but it does not indicate whether the design of that nest satisfies a hen's nesting motivation. Hens that are satisfied with the nest resources exhibit characteristic settled nesting behaviour including less activity and longer...

  12. The effects of cage color and light intensity on rat affect during heterospecific play

  14. Prisoners in War: Zoos and Zoo Animals During Human Conflict 1870-1947

    | Contributor(s):: Clelly Johnson

        Animals are sentient beings capable of many of the same feelings experienced by humans. They mourn a loss, they feel love and loyalty, and they experience fear. During wars and conflicts, fear is a prevailing emotion among humans, who worry for their wellbeing. Animals,...

  15. A Decade of Progress toward Ending the Intensive Confinement of Farm Animals in the United States

    | Contributor(s):: Sara Shields, Paul Shapiro, Andrew Rowan

    In this paper, the Humane Society of the United States (HSUS) farm animal protection work over the preceding decade is described from the perspective of the organization. Prior to 2002, there were few legal protections for animals on the farm, and in 2005, a new campaign at the HSUS began to...

  16. Think Outside the Cage: Moving Towards New Understandings of Companion Rabbits

    | Contributor(s):: Ruthann Drummond

    Rabbits are the third most common companion mammal in Western homes, and their popularity continues to rise. However, they are also one of the most broadly used animal resources around the world, commonly being bred for their food, their fur, and their utility as biological models in animal...

  17. Blue foxes' ( Vulpes lagopus) motivation to gain access and interact with various resources

    | Contributor(s):: Koistinen, T., Korhonen, H. T., Hamalainen, E., Mononen, J.

    We analysed the willingness of blue foxes ( Vulpes lagopus) to work for and utilise five resources: a platform, wooden block, sand floor, nest box and empty space. Ten juvenile blue fox males were housed singly in apparatus consisting of three cages connected with one-way doors through the walls...

  18. Environmentally enriching American mink ( Neovison vison) increases lymphoid organ weight and skeletal symmetry, and reveals differences between two sub-types of stereotypic behaviour

    | Contributor(s):: Diez-Leon, M., Bursian, S., Galicia, D., Napolitano, A., Palme, R., Mason, G.

    Enrichment studies for wild carnivores (e.g., in zoos) are often short-term, use enrichments of unknown motivational significance, and focus on glucocorticoids and stereotypic behaviour (SB), ignoring other stress-relevant variables. Our study assessed the broad behavioural and physiological...

  19. Practical physical and behavioral measures to assess the socialization spectrum of cats in a shelter-like setting during a three day period

    | Contributor(s):: Slater, M., Garrison, L., Miller, K., Weiss, E., Makolinski, K., Drain, N., Mirontshuk, A.

    Animal welfare organizations routinely accept large numbers of cats with unknown histories, and whose backgrounds vary from well-socialized pets to cats that have had little or no contact with humans. Agencies are challenged with making the determination of socialization level in a highly...

  20. 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...
