  1. 'Animal Ethics Dilemma': an interactive learning tool for university and professional training

    Contributor(s):: Hanlon, A. J., Algers, A., Dich, T., Hansen, T., Loor, H., Sandoe, P.

    'Animal Ethics Dilemma' is a freely available computer-supported learning tool (www.animalethicsdilemma.net or www.aedilemma.net) which has been developed primarily for veterinary undergraduates but is applicable also to students in other fields of animal science. The objectives of the computer...

  2. A behavioural comparison of New Zealand White rabbits ( Oryctolagus cuniculus ) housed individually or in pairs in conventional laboratory cages

    Contributor(s):: Chu, L. R., Garner, J. P., Mench, J. A.

    Despite their gregarious nature, rabbits used for research are often housed individually due to concerns about aggression and disease transmission. However, conventional laboratory cages restrict movement, and rabbits housed singly in these cages often perform abnormal behaviours, an indication...

  3. A breeding goal to improve the welfare of sheep

    Contributor(s):: Scobie, D. R., Bray, A. R., O'Connell, D.

    This paper examines the practical and welfare implications of breeding a polled sheep with a short tail, devoid of wool on the head, legs, belly and breech, which has been proposed as a breeding goal (Scobie et al., Proceedings of the New Zealand Society of Animimal Production 57 (1997) 84-87)....

  4. A brief note on the effects of novel enrichment on an unwanted behaviour of captive bonobos

    Contributor(s):: Csatadi, A., Leus, K., Pereboom, J. J. M.

    Animals in captivity may show undesirable behaviour when they are not sufficiently challenged, making it essential for their well-being to provide daily enrichment to zoo animals. Primates need a regular replacement with novel enrichment objects to prevent them from getting bored and look for...

  5. A brief note on the validation of a system for recording lying behaviour in dairy cows

    Contributor(s):: O'Driscoll, K., Boyle, L., Hanlon, A.

    The duration and frequency of lying behaviour and the time spent standing are behavioural indicators of cow comfort. The objective of this study was to validate a robustly designed datalogger (DL) for recording standing and lying behaviour of cows at pasture. The datalogger consists of an...

  6. A cage without a view increases stress and impairs cognitive performance in rats

    Contributor(s):: Harris, A. P., D'Eath, R. B., Healy, S. D.

    Single housing is believed to be chronically stressful and to have a negative impact on welfare and cognition in rats (Rattus norvegicus). However, single housing does not consistently evoke stress-like responses nor does it consistently impair cognitive performance. In an experiment in which all...

  7. A case control study of on-farm risk factors for tail biting in pigs

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

  8. A case study employing operant conditioning to reduce stress of capture for red-bellied tamarins ( Saguinus labiatus )

    Contributor(s):: Owen, Y., Amory, J. R.

    Traditional techniques used to capture New World monkeys, such as net capture, can induce high levels of acute stress detrimental to welfare. Alternatively, training nonhuman animals via operant conditioning to voluntarily participate in husbandry and/or veterinary practices is accepted as a...

  9. A case study of orangutan and siamang behavior within a mixed-species zoo exhibit

    Contributor(s):: Pearson, E. L., Davis, J. M., Litchfield, C. A.

    This empirical case study assessed the behavior and welfare of 2 orangutans (Pongo abelii) and 2 siamangs (Symphalangus syndactylus) within a mixed-species zoo exhibit. The study used instantaneous scan-sampling to record behavior, location, and interspecies proximity over 174 hr and...

  10. A case study: fecal corticosteroid and behavior as indicators of welfare during relocation of an Asian elephant

    Contributor(s):: Laws, N., Ganswindt, A., Heistermann, M., Harris, M., Harris, S., Sherwin, C.

    This study was a preliminary investigation of an enzyme immunoassay for measuring fecal glucocorticoid metabolites in a male Asian elephant (Elephas maximus) by investigating changes in behavior and cortisol metabolite excretion associated with a putative stressful event. The study collected...

  11. A case study: the effect of visitors on two captive pumas with respect to the time of the day

    Contributor(s):: Maia, C. M., Volpato, G. L., Santos, E. F.

    This study analyzed the effects of noise levels and number of visitors on the behaviors of a mother puma and her daughter in a zoo environment with respect to the time of day. The study monitored visitation (noise and number) over two 1-week periods (4 weeks between periods) and frequency of...

  12. A close keeper-nonhuman animal distance does not reduce undesirable behavior in contact yard goats and sheep

    Contributor(s):: Anderson, U. S., Maple, T. L., Bloomsmith, M. A.

    This study investigated the relation between zookeeper-nonhuman animal distance and the undesirable behaviour that goats and sheep exhibited toward visitors of Zoo Atlanta's (Georgia, USA) contact yard. It hypothesized that a close distance between keeper and animal would be associated with a...

  13. A combination of behavioral and physiological indicators for assessing pig welfare on the farm

    Contributor(s):: Candiani, D., Salamano, G., Mellia, E., Doglione, L., Bruno, R., Toussaint, M., Gruys, E.

    The purpose of this research was to identify pig welfare indicators that could help in recognizing stressful practices on farm. The study evaluated behavioral and physiological indicators (cortisol and negative acute phase proteins) in 2 groups of 20 female pigs 4 months old after a 48-hr...

  14. A comparative approach to the study of Keeper-Animal Relationships in the zoo. (Special Issue: Zoo animal welfare.)

    Contributor(s):: Carlstead, K.

    Research on intensively farmed animals over the past 25 years has shown that human-animal interactions, by affecting the animal's fear of humans, can markedly limit the productivity and welfare of farm animals. This article begins to explore some of the factors that need to be considered to...

  15. A comparative study of the influence of social housing conditions on the behaviour of captive tigers ( Panthera tigris )

    Contributor(s):: Rouck, M. de, Kitchener, A. C., Law, G., Nelissen, M.

    Nowadays, zoos are increasingly concerned with animal welfare as public expectations and knowledge of the needs of captive animals increases. Although many zoos try to provide all sorts of enrichment for their big cats, the importance of social enrichment is not yet fully understood. This study...

  16. A comparative study of the well-being of piglets reared conventionally and in cages

    Contributor(s):: Putten, G. Van, Dammers, J.

  17. A comparison of attachment levels of adopters of cats: fee-based adoptions versus free adoptions

    Contributor(s):: Weiss, E., Gramann, S.

    Nonhuman animal welfare professionals have been critical of adoption programs that do not charge a fee for adult cats, despite the high euthanasia rate for cats due to a reported lack of homes. The argument against the free cat adoptions cites a devaluation of the cat, which may affect the...

  18. A comparison of Bahamian cat and dog caregivers on New Providence

    Contributor(s):: Fielding, W. J.

    This article offers the first comparison of actions and attitudes of Afro-Caribbean caregivers who keep only cats or only dogs. A total of 330 Bahamian caregivers found that women primarily keep cats; men primarily keep dogs. Cat keepers were more attached to their companion animals but no more...

  19. A comparison of operant responding by farrowing sows for food and nest-building materials

    Contributor(s):: Hutson, G. D.

    In experiments on 4 days immediately before and after parturition with 16 sows trained to lift a lever to gain access to either a box containing straw, a box containing sticks, an empty box, or a food drop, sows lifted more for food than for the empty box or nest-building materials. On any day...

  20. A comparison of social and environmental enrichment methods for laboratory housed dogs

    Contributor(s):: Hubrecht, R. C.

    48 Beagles in 4 equal groups: (controls; opportunities for social contacts with conspecifics; given 30 s/day of intensive handling; and provided with 3 different toys/chews permanently suspended in the pen (Rawhide, Gumabone chew and a piece of plastic tubing)) were observed for a total of 432 h....
