  1. The effect of four different feeding regimes on rabbit behaviour

    Contributor(s):: Prebble, J. L., Langford, F. M., Shaw, D. J., Meredith, A. L.

    Dietary composition and presentation impacts on the behaviour of animals, and failure to provide a suitable diet can lead to reduced welfare through the development of poor health, the inability to express normal behaviours and the development of abnormal behaviours. This study assessed the...

  2. Explaining prehistoric variation in the abundance of large prey: a zooarchaeological analysis of deer and rabbit hunting along the Pecho Coast of Central California

    Contributor(s):: Brian F. Codding, Judith F. Porcasi, Terry L. Jones

    Three main hypotheses are commonly employed to explain diachronic variation in the relative abundance of remains of large terrestrial herbivores: (1) large prey populations decline as a function of anthro pogenic overexploitation; (2) large prey tends to increase as a result of increasing social...

  3. 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...

  4. Comparative study of trophic behaviour and herd structure in wild and feral goats living in a Mediterranean island: management implications

    Contributor(s):: Rivera-Sanchez, L., Cassinello Roldan, J., Baraza Ruiz, E., BartolomeFilella, J.

    The aim of this study was to compare the trophic behaviour and the social structure of Majorcan wild goats and feral goats present in the island of Majorca. The former are descendants of an ancestral goat ecotype introduced in the island in the late Neolithic, whereas feral goats come from...

  5. Effect of forage presentation on feed intake behaviour in stabled horses

    Contributor(s):: Ellis, A. D., Fell, M., Luck, K., Gill, L., Owen, H., Briars, H., Barfoot, C., Harris, P.

    In some stabled horses, the lack of foraging opportunity leads to a reduction in chewing time with consequent negative impacts on the digestive system and potentially development of stereotypies. This study aimed to compare the effect of four types of haynets on feed intake behaviour in stabled...

  6. The effects of a high-starch or high-fibre diet on equine reactivity and handling behaviour

    Contributor(s):: Bulmer, L., McBride, S., Williams, K., Murray, J. A.

    Increasing performance work in the horse is often associated with a reduction in the forage ration and an increase in concentrates, usually in the form of high-starch cereal grains. This type of diet has been associated with stereotypic behaviours and health problems. High-starch diets are also...

  7. Domesticated landscapes : the subsistence ecology of plant and animal domestication

    Contributor(s):: Terrell, John Edward

  8. In the company of humans

    Contributor(s):: Terborgh, John

  9. The transition from foraging to farming : the archaeozoological perspective in Anatolia

    Contributor(s):: Buitenhuis, Hijlke

  10. Development of early foraging behaviour of domestic chicks in varying social contexts

    Contributor(s):: Gajdon, G. K., Mundwiler, B., Stauffacher, M.

    Two aspects of foraging development might be crucial to learning in precocial chicks: what food particles look like and what food sites look like. Previous research indicates that there are innate dispositions for particle preferences and for preferring the type of food sites experienced between...

  11. Investigating anhedonia in a non-conventional species: do some riding horses Equus caballus display symptoms of depression?

    Contributor(s):: Fureix, C., Beaulieu, C., Argaud, S., Rochais, C., Quinton, M., Henry, S., Hausberger, M., Mason, G.

    Investigating depression-like conditions in animals is methodologically challenging, but potentially important for welfare. Some riding horses display 'withdrawn' states of inactivity and low responsiveness that resemble the reduced engagement with the environment shown by certain depressed...

  12. Pushed to the limit: food abundance determines tag-induced harm in penguins

    Contributor(s):: Wilson, R. P., Sala, J. E., Gomez-Laich, A., Ciancio, J., Quintana, F.

    The energetic costs of animal movement change with body condition, although the consequences of this for foraging efficiency are rarely considered. We deployed externally attached devices to Magellanic penguins ( Spheniscus magellanicus), known to increase the costs of swimming via increased drag...

  13. The relevance of variations in group size and phenotypic appearance on the behaviour and movement patterns of young domestic fowl

    Contributor(s):: Liste, G., Campderrich, I., Beltran Heredia, I. de, Estevez, I.

    Variations in the group size of laying hens might increase the risk of undesired behaviours with important consequences for the birds' health and welfare. However, larger groups housed at constant densities also translate into larger enclosures that may increase space efficiency, therefore...

  14. The risk factors affecting the development of vent pecking and cannibalism in free-range and organic laying hens

    Contributor(s):: Lambton, S. L., Knowles, T. G., Yorke, C., Nicol, C. J.

    Injurious pecking remains one of the biggest animal welfare and economic challenges for free-range egg producers. This prospective epidemiological study investigated the development of vent pecking (VP) and cannibalism on 62 free-range and organic UK farms (119 flocks). Flocks were visited at 25...

  15. Identifying sustainability issues for soymeal and beef production chains

    Contributor(s):: Kamali, F. P., Meuwissen, M. P. M., Boer, I. J. M. de, Stolz, H., Jahrl, I., Garibay, S. V., Jacobsen, R., Driesen, T., Oude Lansink, A. G. J. M.

    The expansion of livestock production throughout the world has led to increased demand for high protein animal feed. This expansion has created economic benefits for livestock farmers and other actors in the chain, but also resulted in environmental and social side effects. This study aims to...

  16. 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...

  17. A survey of abnormal repetitive behaviors in North American river otters housed in zoos

    Contributor(s):: Morabito, P., Bashaw, M. J.

    Stereotypic behaviors, indicating poor welfare and studied in a variety of species (especially carnivores), appear related to characteristics of current and past environments. Although North American river otters (Lontra canadensis) often develop abnormal, repetitive, possibly stereotypic...

  18. 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...

  19. Effects of environmental complexity and temporary captivity on foraging behavior of wild-caught meadow voles

    Contributor(s):: Kozuch, A. E., McPhee, M. E.

    Increased housing of wild nonhuman animals in captivity for conservation, research, and rehabilitation has revealed the importance of systematically analyzing effects of the captive environment on behavior. This study focused on the effects of complexity and time held in captivity on foraging...

  20. Frustrated appetitive foraging behavior, stereotypic pacing, and fecal glucocorticoid levels in snow leopards ( Uncia uncia ) in the Zurich Zoo

    Contributor(s):: Burgener, N., Gusset, M., Schmid, H.

    This study hypothesized that permanently frustrated, appetitive-foraging behavior caused the stereotypic pacing regularly observed in captive carnivores. Using 2 adult female snow leopards (U), solitarily housed in the Zurich Zoo, the study tested this hypothesis experimentally with a novel...
