  1. The effects of feeding space on the behavioural responses of cattle during rest periods offered as part of long-distance transportation

    Contributor(s):: Ross, M., Widowski, T. M., Haley, D. B.

  2. The concept of behavioural needs in contemporary fur science: do we know what American mink (Mustela vison) really need?

    Contributor(s):: Kornum, A. L., Rocklinsberg, H., Gjerris, M.

  3. A novel emotional and cognitive approach to welfare phenotyping in rainbow trout exposed to poor water quality

    Contributor(s):: Colson, V., Mure, A., Valotaire, C., Le Calvez, J. M., Goardon, L., Labbé, L., Leguen, I., Prunet, P.

    Recent scientific evidence for fish sentience has stressed the need for novel sentience-based detection tools of fish welfare impairment in commercial farms. In order to mimic a well-characterised stress situation, rainbow trout (Oncorhynchus mykiss) were exposed to poor water quality (hypoxia...

  4. Animal welfare and organic aquaculture in open systems

    Contributor(s):: Cottee, S. Y., Petersan, P.

    The principles of organic farming espouse a holistic approach to agriculture that promotes sustainable and harmonious relationships amongst the natural environment, plants and animals, as well as regard for animals' physiological and behavioral needs. However, open aquaculture systems - both...

  5. Behaviour of juvenile mud crabs Scylla serrata in aquaculture: response to odours of moulting or injured crabs

    | Contributor(s):: Wall, D., Paterson, B., Mohan, R.

    Behaviour of juvenile mud crabs, Scylla serrata (70–90 mm carapace width, CW) were observed in response to odours of moulting and injured conspecifics and food (pilchard) under controlled flow conditions using bioassay technique. This study was undertaken to better...

  6. Behaviour, synchrony and welfare of Pekin ducks in relation to water use

    | Contributor(s):: Waitt, C., Jones, T., Dawkins, M. S.

    The method of providing bathing water to commercially farmed ducks presents potential logistic, welfare and health issues. Welfare may be compromised if ducks do not have access to water in which they can at least dip their heads and spread water over their feathers. However maintaining hygiene...

  7. Circadian drinking during ad libitum and restricted feeding in pygmy goats

    | Contributor(s):: Rossi, R., Prete, E. del, Rokitzky, J., Scharrer, E.

    Eating and drinking of 8 pygmy goats, 3-8 years old, 30-42 kg liveweight, were recorded during ad libitum and restricted feeding conditions. During ad libitum conditions, water and feed intake occurred throughout the day with a circadian distribution of feed and water intake showing peaks at the...

  8. Effect of acute histamine and pentagastrin on voluntary food intake in growing chickens

    | Contributor(s):: Saadoun, A., Alvarez, A. F., Cabrera-Saadoun, M. C.

    Seven male chickens, 5 weeks old, were injected intraperitoneally with histamine 0, 500 or 1000 micro g/kg body weight. Feed intake was measured at 6, 15, 30, 45, 60, 90 and 120 min and water intake at 15, 30, 45, 60, 90 and 120 min after injection of histamine. A second experiment was carried...

  9. Influence of cage enrichment on aggressive behaviour and physiological parameters in male mice

    | Contributor(s):: Loo, P. L. P. van, Kruitwagen, C. L. J. J., Koolhaas, J. M., Weerd, H. A. van de, Zutphen, L. F. M. van, Baumans, V.

    From welfare perspective group, housing of mice is preferred over individual housing. Group housing of male laboratory mice, however, often leads to problems due to excessive aggressive behaviour. In our search for management and housing modifications to decrease aggression in group-housed male...

  10. Taste threshold determination and side-preference in captive cockatiels ( Nymphicus hollandicus )

    | Contributor(s):: Matson, K. D., Millam, J. R., Klasing, K. C.

    The taste thresholds of caged cockatiels (Nymphicus hollandicus) for aqueous solutions of sodium chloride, citric acid, and sucrose were studied using two-choice taste-preference tests. The effects of location on the threshold were tested by putting the flavoured solution in either the preferred...

  11. Thwarting of behaviour in different contexts and the gakel-call in the laying hen

    | Contributor(s):: Zimmerman, P. H., Koene, P., Hooff, J. A. R. A. M. van

    Earlier studies have shown that thwarting of feeding behaviour in the laying hen is expressed through a specific vocalization, the gakel-call. The first aim of this study was to investigate whether the effect of deprivation per se on the occurrence of gakel-calls can be distinguished from the...

  12. Burdizzo castration of calves less than 1-week old with and without local anaesthesia: short-term behavioural responses and plasma cortisol levels

    | Contributor(s):: Boesch, D., Steiner, A., Gygax, L., Stauffacher, M.

    Castration of calves over 3 weeks of age is considered a painful procedure. It is less clear whether and how much pain is caused by this procedure in very young calves. The aim of the present study was to determine the short-term pain response of 30 calves less than 1-week of age to Burdizzo...

  13. Cattle grazing behavior with season-long free-choice access to four forage types

    | Contributor(s):: Fehmi, J. S., Karn, J. F., Ries, R. E., Hendrickson, J. R., Hanson, J. D.

    This experiment investigated how season-long, free-choice grazing affected weekly cattle grazing behaviour and resource use. Our objectives were to determine if known forage preferences change through the season, if feedbacks from previous grazing intensity affect current use, and if resources...

  14. Effects of forced flavor exposure on food neophobia

    | Contributor(s):: Cheney, C. D., Miller, E. R.

    For 5 days, 18 male albino rats were fed on food pellets ad libitum, but were only allowed 10 min access to water daily. After this they received mashed pellets (pellets mixed with water) for 3 days. Then rats (n=6 per group) were assigned to forced-exposure to mint-flavoured water,...

  15. Effects of social "stressors" on belly-nosing behaviour in early-weaned piglets: is belly-nosing an indicator of stress?

    | Contributor(s):: Gardner, J. M., Duncan, I. J. H., Widowski, T. M.

    Belly-nosing is a behaviour pattern commonly observed in early-weaned piglets. Although belly-nosing has been referred to as an indicator of stress, the factors involved in its causation are unknown. The objective of this study was to determine if the differences in stress at weaning influence...

  16. Manipulating cattle distribution with salt and water in large arid-land pastures: a GPS/GIS assessment

    | Contributor(s):: Ganskopp, D.

    Several of the problems associated with grazing animals in extensive settings are related to their uneven patterns of use across the landscape. After fencing, water and salt are two of the most frequently used tools for affecting cattle distribution in extensive settings. Cattle are attracted to...

  17. The effects of two different amounts of dietary grain on the digestibility of the diet and behaviour of intensively managed horses

    | Contributor(s):: Freire, R., Clegg, H. A., Buckley, P., Friend, M. A., McGreevy, P. D.

    The current experiment examined the effect of switching from a moderate grain diet to a high grain diet, as are typically fed to intensively managed horses, on some behavioural and physiological (oro-caecal transit time [OCTT], digestibility, plasma cortisol concentrations and heart rate)...

  18. Piglets' weaning behavioural response is influenced by quality of human-animal interactions during suckling

    | Contributor(s):: Sommavilla, R., Hotzel, M. J., Costa, O. A. D.

  19. The impacts of profound wildlife experiences

    | Contributor(s):: Smith, L. D. G., Ham, S. H., Weiler, B. V.

    Profound experiences with wildlife have been identified as potential triggers for changing the way people feel and act towards wildlife. However, there has been little systematic research into the impacts of these experiences on the lives of those who experience them. This qualitative study...
