  1. Are the livestock guarding dogs where they are supposed to be?

    Contributor(s):: Zingaro, Margherita, Salvatori, Valeria, Vielmi, Luisa, Boitani, Luigi

    In many parts of the world, livestock guarding dogs (LGDs) are considered one of the most powerful prevention tools against carnivore predation on domestic animals, but how they behave when left unsupervised with their flock on pastures is mostly unknown. We monitored 29 LGDs with GPS (Global...

  2. 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...

  3. Condensed tannins reduce browsing and increase grazing time of free-ranging goats in semi-arid savannas

    Contributor(s):: Mkhize, N. R., Heitkonig, I. M. A., Scogings, P. F., Dziba, L. E., Prins, H. H. T., Boer, W. F. de

    Tannin concentrations fluctuate spatially and temporally within and among plant species, with consequences for forage quality of herbivores. The extent to which these fluctuations influence foraging activities of goats is not fully understood. While accounting for the effects of the time of the...

  4. 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...

  5. No increased stress response in horses on small and electrically fenced paddocks

    Contributor(s):: Glauser, A., Burger, D., Dorland, H. A. van, Gygax, L., Bachmann, I., Howald, M., Bruckmaier, R. M.

    Regular free movement is an important factor for the wellbeing of horses, reducing the risk of behavioural disorders as well as maintaining bodily functions healthy. Currently animal welfare legislations in several countries require minimal stay times in outdoor enclosures. However, clear legal...

  6. Reaching new heights: the effect of an environmentally enhanced outdoor enclosure on Gibbons in a zoo setting

    Contributor(s):: Anderson, M. R.

    Gibbons have adapted to live in the canopy layer of the rainforest. Gibbons in the wild predominantly spend their time high in the trees resting, traveling, and foraging for food. Comparatively, gibbons in the zoo often rest and search for their food terrestrially. The purpose of this study was...

  7. Utilization of matrix population models to assess a 3-year single treatment nonsurgical contraception program versus surgical sterilization in feral cat populations

    Contributor(s):: Budke, C. M., Slater, M. R.

    This study constructed matrix population models to explore feral cat population growth for a hypothetical population (a) in the absence of intervention; (b) with a traditional surgical sterilization-based trap, neuter, and return program; and (c) with a single treatment 3-year nonsurgical...

  8. Comprehension and utilisation of pointing gestures and gazing in dog-human communication in relatively complex situations

    Contributor(s):: Lakatos, G., Gacsi, M., Topal, J., Miklosi, A.

    The aim of the present investigation was to study the visual communication between humans and dogs in relatively complex situations. In the present research, we have modelled more lifelike situations in contrast to previous studies which often relied on using only two potential hiding locations...

  9. Status quo of the personality trait evaluation in horse breeding: judges' assessment of the situation and strategies for improvement

    Contributor(s):: Borstel, U. K. von, Pasing, S., Gauly, M., Christmann, L.

    Recently, concerns about the validity of the evaluation of personality traits in horse breeding have been raised. For that reason, the aim of the present study was to assess the current status of personality trait evaluation in horse breeding. A survey was conducted among all station performance...

  10. Attitudes towards farm animals as a part of belief systems

    Contributor(s):: Vinnari, M., Rasanen, P., Jokinen, P.

  11. Providing 'get-away bunks' and other enrichments to primiparous adult female mink improves their reproductive productivity

    Contributor(s):: Buob, M., Meagher, R., Dawson, L., Palme, R., Haley, D., Mason, G.

  12. Feeding behaviour of sheep on shrubs in response to contrasting herbaceous cover in rangelands dominated by Cytisus scoparius L

    Contributor(s):: Pontes, L. da S., Agreil, C., Magda, D., Gleizes, B., Fritz, H.

    The foraging responses of ewes faced with a diversity of feed items and their effects on broom (Cytisus scoparius L.) consumption were examined. The experiment was conducted on a farm in the autumn with ewes (n=33) grazing three small paddocks (0.44 ha on average, for at least 10 days each)...

  13. Space use as an indicator of enclosure appropriateness: a novel measure of captive animal welfare

    Contributor(s):: Ross, S. R., Schapiro, S. J., Hau, J., Lukas, K. E.

    Empirical measures of animal behavior and space use within the captive environment can provide critical information about animals' requirements, preferences and internal states. The trend toward naturalistic environments has shown promise in terms of behavioral benefits for animals such as great...

  14. Relationships among variables indexing selective grazing behavior of goats

    Contributor(s):: Ganskopp, D., Cruz, R., Fajemisin, B.

    Although portable computers presently allow documentation of real-time grazing behaviour under field conditions, the task of selecting proper and easily recorded variables to test their hypotheses still exists. In view of this, the relationships among variables describing grazing behaviour and...

  15. Legal implications in development and use of expert systems in agriculture

    Contributor(s):: Downs, W., Newton, K. A.

    Applications of Artificial Intelligence, particularly Expert Systems, are rapidly increasing. This science promises to give computer-based systems the capability of reasoning and decision making.
