  1. 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....

  2. 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,...

  3. 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...

  4. 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...

  5. 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...

  6. Effect of cage type on fecal corticosterone concentration in buck rabbits during the reproductive cycle

    Contributor(s):: Cornale, P., Macchi, E., Renna, M., Prola, L., Perona, G., Mimosi, A.

    Fecal corticosterone concentration (FCC) was measured in 14 buck rabbits individually housed in standard-dimension cages (SC) or in bigger cages (BC; with a volume more than double that of SC and equipped with a plastic foot mat) during 4 consecutive reproductive cycles. Cage type 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. Stereotypic mice are aggressed by their cage-mates, and tend to be poor demonstrators in social learning tasks

    Contributor(s):: Harper, L., Choleris, E., Ervin, K., Fureix, C., Reynolds, K., Walker, M., Mason, G.

    Stereotypic behaviours (SBs) are linked with behavioural inflexibility and resemble symptoms of autism, suggesting that stereotypic animals could have autistic-like social impairments. SBs are also common in caged mice. We therefore hypothesised relationships between stereotypic and social...

  9. An ethological approach to determining housing requirements of gamebirds in raised laying units

    Contributor(s):: Matheson, S. M., Donbavand, J., Sandilands, V., Pennycott, T., Turner, S. P.

    Each year, the UK rears around 20-30 million pheasants and 3-6 million red-legged partridges for shooting purposes. However, welfare organisations and some members of the gamebird industry itself have raised concerns about the use of raised laying units for breeding gamebirds. Although the...

  10. Stereotypic behaviours in Melopsittacus undulatus: behavioural consequences of social and spatial limitations

    Contributor(s):: Polverino, G., Manciocco, A., Vitale, A., Alleva, E.

    The demand for parrots for pet and scientific purposes is an increasing phenomenon. Yet, the cognitive complexity of these animals makes it difficult to fully satisfy their eco-ethological needs in captivity, and strategies commonly adopted for their husbandry are often unsuccessful in...

  11. The effects of witnessing managemental procedures during the light versus the dark phase of the light cycle on behaviour, performance and welfare of laboratory rats

    Contributor(s):: Abou-Ismail, U. A., Mohamed, R. A., El-Kholya, S. Z.

    Research has indicated that witnessing managemental procedures are stressful to laboratory rats. Yet there has been little investigation into whether the time of witnessing these procedures affects behaviour and welfare in these animals. Ninety-six rats, representing two batches, were used in...

  12. Environmental factors that affect the behavior and welfare of domestic cats ( Felis silvestris catus) housed in cages

    Contributor(s):: Stella, J., Croney, C., Buffington, T.

    Understanding environmental factors that affect the behavior of cats in cages is important if caretakers are to improve the welfare of confined cats. The aim of this study was to examine the effects of the macro (room) and micro (cage) environments on cat behavior and their implications for cat...

  13. Abnormal Behavior in Caged Birds Kept as Pets

    Contributor(s):: van Hoek, Caroline S., Ten Cate, Carel

    There are a limited number of studies dealing with abnormal behavior in caged birds kept as pets. However, these studies demonstrate the presence of abnormal behavior in both songbirds and parrots. Ethological studies on these birds, as well as studies on domestic and zoo birds, indicate that...

  14. Abnormal behavior in caged birds kept as pets

    Contributor(s):: Hoek, C. S. van, Cate, C. ten

    There are a limited number of studies dealing with abnormal behavior in caged birds kept as pets. However, these studies demonstrate the presence of abnormal behavior in both songbirds and parrots. Ethological studies on these birds, as well as studies on domestic and zoo birds, indicate that...

  15. Animal welfare issues in the poultry industry: is there a lesson to be learned? (Special issue: food animal husbandry and the new millennium)

    Contributor(s):: Duncan, I. J. H.

    Many of the conditions in which poultry live and the procedures to which they are subjected compromise their welfare. This article describes these welfare problems in the hope that they may serve as warnings to the rest of animal agriculture, which then might take steps to avoid the same...

  16. Cage size preference in rats in the laboratory

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

    The size of an enclosure is an integral part of how well it accommodates a nonhuman animal's welfare; however, most enrichment studies concentrate on modifying the area inside the enclosure rather than enlarging it. It has been suggested that rats have little need for more cage space, but there...

  17. Cage use and feeding height preferences of captive common marmosets ( Callithrix j. jacchus ) in two-tier cages

    Contributor(s):: Buchanan-Smith, H. M., Shand, C., Morris, K.

    Determining appropriate feeding regimes has important welfare implications for captive primates. This study examined the preference of food bowl heights in 6 pairs of common marmosets (Callithrix jacchus) housed in a 2-tier cage system. Given that marmosets are arboreal and spend most of their...

  18. Effect of breed, cage type, and reproductive phase on fecal corticosterone levels in doe rabbits

    Contributor(s):: Prola, L., Cornale, P., Renna, M., Macchi, E., Perona, G., Mimosi, A.

    Fecal corticosterone concentration (FCC) is increasingly being used as a noninvasive indicator of stress in assessment of nonhuman animal welfare. The aim of this study was to evaluate effects of breed, cage type, reproductive phase, and their interactions on FCC levels in doe rabbits. A total of...

  19. Laboratory rodent welfare: thinking outside the cage

    Contributor(s):: Balcombe, J.

    This commentary presents the case against housing rats and mice in laboratory cages; the commentary bases its case on their sentience, natural history, and the varied detriments of laboratory conditions. The commentary gives 5 arguments to support this position: (a) rats and mice have a high...

  20. Legal loophole for subminimal floor area for caged macaques

    Contributor(s):: Reinhardt, V.

    Macaques are biologically adapted to an arboreal or semiarboreal lifestyle. They spend much or most of the day and all of the night in elevated locations well off the ground as a safeguard against predators including humans. When they are on the ground during an alarming situation, they...
