  1. The associations between animal-based welfare measures and the presence of indicators of food safety in finishing pigs

    Contributor(s):: Alpigiani, I., Bacci, C., Keeling, L. J., Salman, M. D., Brindani, F., Pongolini, S., Hitchens, P. L., Bonardi, S.

    Stressful housing and management practices affect animals, potentially increasing their receptiveness to pathogens. Since some pathogens do not lead to clinical signs of sickness, subclinical pigs could enter the food-chain, contaminating carcases and offal at slaughter, representing a threat to...

  2. Oestrus odours from rats and mares: behavioural responses of sexually naive and experienced rats to natural odours and odorants

    Contributor(s):: Nielsen, B. L., Jerome, N., Saint-Albin, A., Ouali, C., Rochut, S., Zins, E. L., Briant, C., Guettier, E., Reigner, F., Couty, I., Magistrini, M., Rampin, O.

    Three experiments were conducted to investigate if sexual experience affects the behavioural response of male rats to natural oestrus odours and constituent odorants. In the first experiment, 16 male Brown Norway rats were exposed before and after sexual training to four odours (1-hexanol (herb...

  3. Reconsidering coprophagy as an indicator of negative welfare for captive chimpanzees

    Contributor(s):: Hopper, L. M., Freeman, H. D., Ross, S. R.

    For captive chimpanzees, 'abnormal' behaviours include behaviours observed only in captivity (i.e. species-atypical behaviours) and those that are performed at higher rates in captivity compared to in the wild. Both types are used as metrics for evaluating captive primates' welfare. However,...

  4. 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...

  5. Program animal welfare: using behavioral and physiological measures to assess the well-being of animals used for education programs in zoos

    Contributor(s):: Baird, B. A., Kuhar, C. W., Lukas, K. E., Amendolagine, L. A., Fuller, G. A., Nemet, J., Willis, M. A., Schook, M. W.

    This study investigates program animal welfare using both behavioral and physiological measures in two separate experiments. In Experiment One, we examined possible differences in behavior and fecal glucocorticoid metabolites (FGM) between education, exhibit and off-exhibit armadillos ( N=59)...

  6. Survey of Canada goose feces for presence of Giardia

    Contributor(s):: Ayers, Christopher R., DePerno, Christopher S., Moorman, Christopher E., Stibbs, Henry H., Faust, Angela M.

  7. 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...

  8. The influence of gentle interactions on avoidance distance towards humans, weight gain and physiological parameters in group-housed dairy calves

    Contributor(s):: Lurzel, S., Munsch, C., Windschnurer, I., Futschik, A., Palme, R., Waiblinger, S.

    The quality of the relationship between cattle and their caretakers is important for animal welfare and productivity. Nevertheless, the influence of gentle interactions on group-housed dairy calves has not been thoroughly studied so far. We examined the effects of 42 min of gentle interactions...

  9. Hormonal and behavioural stress responses to capture and radio-collar fitting in free-ranging pampas deer ( Ozotoceros bezoarticus)

    Contributor(s):: Munerato, M. S., Marques, J. A., Caulkettt, N. A., Tomas, W. M., Zanetti, E. S., Trovati, R. G., Pereira, G. T., Palme, R.

    This study evaluated the short-term hormonal and behavioural responses to capture and radio-collar fitting in free-ranging pampas deer ( Ozotoceros bezoarticus). Twenty adult deer (eleven females and nine males) were captured in the South Pantanal wetland (Brazil) and equipped with VHF...

  10. The effects of social interaction and environmental enrichment on the space use, behaviour and stress of owned housecats facing a novel environment

    Contributor(s):: Rehnberg, L. K., Robert, K. A., Watson, S. J., Peters, R. A.

    Every day, millions of domestic cats are held temporarily in captive environments, such as boarding catteries and rescue shelters. Being in confinement can potentially invoke high levels of stress for these animals. Therefore, there is a need to develop appropriate strategies to reduce these...

  11. The danger of contracting salmonellosis from exotic pets

    Contributor(s):: Paul, Siba Prosad, Wilkinson, Rachel, Hawes, Dorothy

  12. Early transfer of mated females into the maternity unit reduces stress and increases maternal care in farm mink

    Contributor(s):: Malmkvist, J., Palme, R.

    Mated mammals on farms are typically transferred to another housing environment prior to delivery. We investigated whether the timing of this transfer - EARLY (Day -36), INTERMEDIATE (Day -18), or LATE (Day -3) relative to the expected day of birth (Day 0) - affects maternal stress, maternal...

  13. Effects of visual contact with zoo visitors on black-capped capuchin welfare

    Contributor(s):: Sherwen, S. L., Harvey, T. J., Magrath, M. J. L., Butler, K. L., Fanson, K. V., Hemsworth, P. H.

    Previous research has suggested that the presence of zoo visitors may be stressful for various primate species, and visual contact with visitors may be the sensory stimuli that mediate visitor effects. We studied a group of black-capped capuchins, Cebus apella, in a controlled experiment,...

  14. Enteric pathogens of dogs and cats with public health implications

    Contributor(s):: Kantere, M., Athanasiou, L. V., Chatzopoulos, D. C., Spyrou, V., Valiakos, G., Kontos, V., Billinis, C.

    Dogs and cats play an important role in modern society, enhancing the psychological and physiological well-being of many people. However, there are well-documented health risks associated with human animal interactions. More specifically, enteric pathogens of zoonotic risk which are transmitted...

  15. Group composition for fattening entire male pigs under enriched housing conditions - influences on behaviour, injuries and boar taint compounds

    Contributor(s):: Holinger, M., Fruh, B., Hillmann, E.

    In organic farming, the production of pork from entire male pigs seems to be the most promising alternative to castration, as organic animal husbandry aims at high standards of animal welfare and elimination of mutilations. However, previous research on behaviour of entire male pigs was mostly...

  16. Head partitions at the feed barrier affect behaviour of goats

    Contributor(s):: Nordmann, E., Barth, K., Futschik, A., Palme, R., Waiblinger, S.

    Space allowance at the feeding places often forces goats to feed in close proximity, that is, less than their individual distances. In consequence, agonistic behaviour may increase as well as stress and injuries, while access to feed may decrease, especially in low-ranking goats. Partitions...

  17. Colorectal cancer screening with odour material by canine scent detection

    Contributor(s):: Sonoda, H., Kohnoe, S., Yamazato, T., Satoh, Y., Morizono, G., Shikata, K., Morita, M., Watanabe, A., Kakeji, Y., Inoue, F., Maehara, Y.
