  1. Online videos indicate human and dog behaviour preceding dog bites and the context in which bites occur

    Contributor(s):: Sara C. Owczarczak-Garstecka, Francine Watkins, Rob Christley, Carri Westgarth

    YouTube videos of dog bites present an unexplored opportunity to observe dog bites directly. We recorded the context of bites, bite severity, victim and dog characteristics for 143 videos and for 56 videos we coded human and dog behaviour before the bite. Perceived bite severity was derived...

  2. Identification and development of measures suitable as potential breeding traits regarding dairy cows' reactivity towards humans

    Contributor(s):: Ebinghaus, A., Ivemeyer, S., Rupp, J., Knierim, U.

    Behavioural indicators of the human-animal relationship (HAR) are predominantly used in animal welfare science. However, the reactivity of dairy cows - as part of the HAR - is also of interest in the context of dairy breeding, due to its estimated moderate heritability. The avoidance distance...

  3. Does group size have an impact on welfare indicators in fattening pigs?

    Contributor(s):: Meyer-Hamme, S. E. K., Lambertz, C., Gauly, M.

    Production systems for fattening pigs have been characterized over the last 2 decades by rising farm sizes coupled with increasing group sizes. These developments resulted in a serious public discussion regarding animal welfare and health in these intensive production systems. Even though large...

  4. Positive reinforcement training for blood collection in grizzly bears ( Ursus arctos horribilis) results in undetectable elevations in serum cortisol levels: a preliminary investigation

    Contributor(s):: Joyce-Zuniga, N. M., Newberry, R. C., Robbins, C. T., Ware, J. V., Jansen, H. T., Nelson, O. L.

    Training nonhuman animals in captivity for participation in routine husbandry procedures is believed to produce a lower stress environment compared with undergoing a general anesthetic event for the same procedure. This hypothesis rests largely on anecdotal evidence that the captive subjects...

  5. On-farm qualitative behaviour assessment in sheep: repeated measurements across time, and association with physical indicators of flock health and welfare

    Contributor(s):: Phythian, C. J., Michalopoulou, E., Cripps, P. J., Duncan, J. S., Wemelsfelder, F.

    Qualitative Behavioural Assessment (QBA) is a 'whole-animal' methodology that assesses the expressive qualities of animal behaviour using terms such as 'tense', 'relaxed', 'anxious', and 'content'. The reliability and validity of QBA as an indicator for on-farm welfare assessment in pigs, cattle,...

  6. Detecting horses' sickness: in search of visible signs

    Contributor(s):: Hausberger, M., Fureix, C., Lesimple, C.

    Assessing sickness in animals, by which we refer to non-specific states involving both physical discomfort and negative emotional states, is a real challenge. In this review, we demonstrate the need for clear and simple indicators of sickness in horses, a species in which suffering is largely...

  7. Manifestation of neuronal ceroid lipofuscinosis in Australian Merino sheep: observations on altered behaviour and growth

    Contributor(s):: Cronin, G. M., Beganovic, D. F., Sutton, A. L., Palmer, D. J., Thomson, P. C., Tammen, I.

    Neuronal ceroid lipofuscinoses (NCL) is an inherited neurodegenerative disorder in children. Presently there is no effective treatment and the disorder is lethal. NCL occur in a variety of non-human species including sheep, which are recognised as valuable large animal models for NCL. This...

  8. Use of Qualitative Behaviour Assessment as an indicator of welfare in donkeys

    Contributor(s):: Minero, M., Costa, E. dalla, Dai, F., Murray, L. A. M., Canali, E., Wemelsfelder, F.

    One of the objectives of the Animal Welfare Indicators project was to develop animal-based indicators to assess donkey welfare, including their emotional state. This study aimed to develop a fixed rating scale of Qualitative Behaviour Assessment (QBA) for donkeys, to evaluate the inter-observer...

  9. Stocking density affects welfare indicators of growing pigs of different group sizes after regrouping

    Contributor(s):: Fu, LingLing, Li, HuiZhi, Liang, TingTing, Zhou, Bo, Chu, QingPo, Schinckel, A. P., Yang, XiaoJing, Zhao, RuQian, Li, PingHua, Huang, RuiHua

    In recent years, the concept of animal welfare began to be accepted by the Chinese people. On some intensive pig farms, the stocking density for growing pigs is too great, leading to decreased animal welfare. In order to study the relationships between stocking density and welfare indicators and...

  10. Behavioural analysis of captive tigers ( Panthera tigris): a water pool makes the difference

    Contributor(s):: Biolatti, C., Modesto, P., Dezzutto, D., Pera, F., Tarantola, M., Gennero, M. S., Maurella, C., Acutis, P. L.

    The activity budgets of seven captive tigers ( Panthera tigris) housed in four zoological gardens (A, B, C, D) were analysed to assess their welfare and to relate it to several variables, including enclosure type, management, and animal history. Behaviours were recorded by instantaneous focal...

  11. What can inactivity (in its various forms) reveal about affective states in non-human animals? A review

    Contributor(s):: Fureix, C., Meagher, R. K.

    Captive/domestic animals are often described as inactive, with the implicit or explicit implication that this high level of inactivity is a welfare problem. Conversely, not being inactive enough may also indicate or cause poor welfare. In humans, too much inactivity can certainly be associated...

  12. Fear and stress measurements in pure and hybrid red-legged partridges

    Contributor(s):: Campo, J. L., Garcia Davila, S., Garcia Gil, M., Torres, O., Santiago Moreno, J.

    The purposes of this study were to examine the duration of induced tonic immobility (a reliable fear indicator considered a passive anti-predator behavioural trait) and two stress indicators (heterophil to lymphocyte ratio, and fluctuating asymmetry of leg length, middle-toe length, and wing...

  13. 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...

  14. Acoustic analysis of cattle ( Bos taurus) mother-offspring contact calls from a source-filter theory perspective

    Contributor(s):: Torre, M. P. de la, Briefer, E. F., Reader, T., McElligott, A. G.

    Cattle vocalisations have been proposed as potential indicators of animal welfare. However, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication...

  15. Can ear postures reliably measure the positive emotional state of cows?

    Contributor(s):: Proctor, H. S., Carder, G.

    Animal welfare science is increasingly concerned with the promotion of positive emotions in animals, yet little is known about how to measure them. We examined whether ear postures in dairy cows were reliable indicators of a low arousal, positive emotional state. We conducted a total of 381, 15...

  16. Emotions in dogs being petted by a familiar or unfamiliar person: validating behavioural indicators of emotional states using heart rate variability

    Contributor(s):: Kuhne, F., Hossler, J. C., Struwe, R.

    Although physical human-dog interactions have an important influence on the human-dog relationship, few studies have proposed the key factors of physical human-dog contact affecting the well-being of dogs. Therefore, our aim was to investigate the effect of physical human-dog contact on the...

  17. Environmental complexity and use of space in slow growing free range chickens

    Contributor(s):: Rodriguez-Aurrekoetxea, A., Leone, E. H., Estevez, I.

    Production environments for meat poultry are generally bi-dimensional open areas where birds tend to cluster along the walls. We investigated the impact of increasing environmental complexity (EC) on slow-growing free-range chickens raised under commercial conditions. The study was conducted in...

  18. Playful handling of laboratory rats is more beneficial when applied before than after routine injections

    Contributor(s):: Cloutier, S., Wahl, K. L., Panksepp, J., Newberry, R. C.

    The ability of positive affective states to counteract negative states engendered by routine medical procedures remains poorly studied. In laboratory rats, positive affect typically associated with rough-and-tumble play can be induced through human "hand play" - the experience of being "tickled"...

  19. Testing three measures of mouse insensibility following induction with isoflurane or carbon dioxide gas for a more humane euthanasia

    Contributor(s):: Moody, C. M., Makowska, I. J., Weary, D. M.

    Laboratory mice are commonly killed via exposure to gradually increasing concentrations of isoflurane and carbon dioxide (CO 2) gas. Once rendered insensible using isoflurane or CO 2, a high concentration of CO 2 is used to decrease time to death. When the switch from isoflurane to a high flow...

  20. Young Blond d'Aquitaine, Angus and Limousin bulls differ in emotional reactivity: relationships with animal traits, stress reactions at slaughter and post-mortem muscle metabolism

    Contributor(s):: Bourguet, C., Deiss, V., Boissy, A., Terlouw, E. M. C.

    The present study investigated relationships between reactivity during tests, stress reactions at slaughter and animal traits in young Blond d'Aquitaine (BA), Limousin (LI) and Angus (AN) bulls. Behavioural and physiological reactivity of animals was evaluated during rearing using a "Human test"...
