Flavour preference acquired via a beverage-induced conditioning and its transposition to solid food: Sucrose but not maltodextrin or saccharin induced significant flavour preferences in pigs
Contributor(s):: Clouard, Caroline, Chataignier, Mathieu, Meunier-Salaün, Marie-Christine, Val-Laillet, David
When exposed to novel food during food transitions, growing pigs often elicit a neophobic response that is responsible for decreased food consumption. Flavour preference conditioning may represent an interesting way to reduce neophobia and improve food intake in growing pigs. The present series...
Do bottlenose dolphins display behavioural response to fish taste?
Contributor(s):: Bouchard, Bertrand, Lisney, Thomas J., Campagna, Sylvie, Célérier, Aurélie
The chemosensory abilities (i.e. taste, smell and trigeminal perception) of odontocete cetaceans are still widely unknown. However, a better understanding of their potential use of these senses would not only improve our knowledge of their behavioural ecology, but also allow us to develop...
Facial expressions and other behavioral responses to pleasant and unpleasant tastes in cats (Felis silvestris catus)
Contributor(s):: Hanson, Michaela, Jojola, Susan M., Rawson, Nancy E., Crowe, Melissa, Laska, Matthias
The goal of the present study was to assess how cats react to tastes previously reported to be preferred or avoided relative to water. To this end, the facial and behavioral reactions of 13 cats to different concentrations of l-Proline and quinine monohydrochloride (QHCl) as well as mixtures with...

Using self-selection to evaluate the acceptance of a new diet formulation by farmed fish
| Contributor(s):: Carlberg, H., Cheng, Ken, Lundh, T., Brannas, E.
The evaluation of new diet composition is commonly achieved by performing time-consuming growth trials, which may negatively impact the welfare of a large number of fish if the feed is not accepted. Instead, the fish's behavioural responses to a new diet composition can be used as a first...
Conditioned taste aversion in the grey fox ( Pseudalopex griseus), in Southern Argentine Patagonia
| Contributor(s):: Nielsen, S., Travaini, A., Vassallo, A. I., Procopio, D., Zapata, S. C.
Attempts to control cougar ( Puma concolor) and culpeo fox ( Pseudalopex culpaeus) populations in Patagonia through poisoning, negatively affects grey foxes ( Pseudalopex griseus) and many other non-target species. It is therefore advisable to develop selective predator control methods. Among a...
Food preference, keeper ratings, and reinforcer effectiveness in exotic animals: the value of systematic testing
| Contributor(s):: Gaalema, D. E., Perdue, B. M., Kelling, A. S.
Food preference describes the behavior of selecting between items for consumption; reinforcer effectiveness is the functional effect of that item in controlling behavior. Food preference and reinforcer effectiveness were examined in giant pandas (Ailuropoda melanoleuca) and African elephants...
Systematic investigation of the stability of food preferences in captive orangutans: implications for positive reinforcement training
| Contributor(s):: Clay, A. W., Bloomsmith, M. A., Marr, M. J., Maple, T. L.
Using preference-assessment tests with humans in conjunction with behavioral modification sessions has been a regular component of almost all operant conditioning programs with mentally challenged humans. This has been very effective in improving the efficiency of behavioral training in these...

Consumer attitudes towards alternatives to piglet castration without pain relief in organic farming: qualitative results from Germany

Choosing a food future: differentiating among alternative food options
| Contributor(s):: Follett, J. R.
This article examines the diversity of food networks that fit within the alternative food system of the United States. While farmers' markets, community supported agriculture schemes, and corporate organic food markets all fit within the alternative food system, they differ greatly in the...
Cockatiels (Nymphicus hollandicus) reject very low levels of plant secondary compounds
| Contributor(s):: Matson, K. D., Millam, J. R., Klasing, K. C.
The rejection thresholds of caged cockatiels (Nymphicus hollandicus) were tested to determine their sensitivity to plant secondary compounds. Both alkaloids and tannins were tested using a two-bottle method in which purified water was always available in one bottle and an aqueous test solution...
Effect of an early bitter taste experience on subsequent feather-pecking behaviour in laying hens
| Contributor(s):: Matauschek, A. H., Beck, P., Rodenburg, T. B.
Recent studies showed that laying hens learn not to peck at bitter-tasting feathers from conspecifics. In the present experiment, feathers of newly hatched chicks were made distasteful by spraying them with a bitter-tasting substance (quinine). It was hypothesized that chicks could detect quinine...
Effects of exposing pigs to moving and odors in a simulated slaughter chute
| Contributor(s):: Krebs, N., McGlone, J. J.
Pigs in the finishing stage are infrequently handled and can be difficult to handle when experiencing novel situations. This study sought to determine the effects of minimal training and a novel odor/taste reward on the ease of handling finishing pigs in a novel environment. Pigs were assigned to...
Strength and persistence of conditioned taste aversion in rats: evaluation of 11 potential compounds
| Contributor(s):: Massei, G., Cowan, D. P.
Conditioned taste aversion (CTA) occurs when animals associate the taste of a food with illness and subsequently avoid that food. CTA can be experimentally induced by adding an undetectable, illness-inducing chemical to food. The use of CTA has been suggested as a humane, non-lethal method for...
Taste threshold determination and side-preference in captive cockatiels (Nymphicus hollandicus)
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...
The effect of feeding enrichment toys on the behaviour of kennelled dogs (Canis familiaris)
| Contributor(s):: Schipper, L. L., Vinke, C. M., Schilder, M. B. H., Spruijt, B. M.
In general, an animal's inability to perform specific behaviours (for example, due to a lack of suitable stimuli or physical restraint) is often viewed as a cause of reduced welfare of animals kept in captivity. There is increasing evidence that the opportunity to display more...
