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...
A new approach to overcoming a yearling Holstein bull's complete lack of motivation to mounting
Contributor(s):: Foote, R. H., Presicce, G. A., Brockett, C. C.
A young Holstein bull, selected for semen evaluation, was presented with a variety of sexual stimuli in an attempt to induce it to mount teaser animals and serve an artificial vagina. The bull was tested on 25 occasions and was scheduled for slaughter at 17 months of age because of a total...
A note on the consistency and specificity of lambs' responses to a stockperson and to their photograph in an arena test
Contributor(s):: Tallet, C., Veissier, I., Boivin, X.
Understanding how farm animals perceive their stockperson is a major challenge, especially for artificially reared animals which are known to show strong attraction to humans. Replacing the stockperson by its photograph in an arena test could be a useful method for standardising human stimuli....
A note on the influence of visual conspecific contact on the behaviour of sheltered dogs
Contributor(s):: Wells, D. L., Hepper, P. G.
The effects of visual contact with other dogs on the behaviour of dogs housed in a rescue shelter were examined. 407 dogs were studied: 212 dogs were housed in cages that allowed for visual contact with dogs in opposite pens; 195 dogs were deprived of visual contact with other dogs by being...
A preliminary study into the effectiveness of stroboscopic light as an aversive stimulus for fish
Contributor(s):: Mesquita, F. de O., Godinho, H. P., Azevedo, P. G. de, Young, R. J.
To reduce fish mortality in nature it is often necessary to expel individuals from areas modified by humans (e.g., dams) where they could be injured or killed. We tested the effectiveness of stroboscopic light as an aversive stimulus for zebrafish (Danio rerio) in captivity. We used six groups of...

Animal Enrichment Strategies for Promoting Natural Behaviors in Captive Populations of Tasmanian Devils (Sarcophilus harrisii)
Contributor(s):: Tierney O\'neal
The population of Tasmanian devils (Sarcophilus harrisii) is in rapid decline due to Devil Facial Tumour Disease, and insurance populations have been created in captivity for potential future introduction into the wild. Many problems can arise within captive animal populations including loss of...
Auditory stimulation as enrichment for zoo-housed Asian elephants ( Elephas maximus )
Contributor(s):: Wells, D. L., Irwin, R. M.
This study explored the effect of auditory stimulation on the behaviour and welfare of four zoo-housed, female Asian elephants (Elephas maximus). All animals were exposed, in an ABA design, to two conditions of auditory stimulation: a 'control' (no auditory stimulation), and an 'experimental'...
Behavioural analysis of a nociceptive event in fish: comparisons between three species demonstrate specific responses
Contributor(s):: Reilly, S. C., Quinn, J. P., Cossins, A. R., Sneddon, L. U.
Nociception is the sensory mechanism by which potentially harmful stimuli are detected in animals and humans. The behavioural responses to noxious stimulation have been studied in two fish species thus far. However, since species-specific differences are seen in mammals, more species need to be...

Do horses generalise between objects during habituation?
Contributor(s):: Christensen, J. W., Zharkikh, T., Ladewig, J.
Habituation to frightening stimuli plays an important role in horse training. To investigate the extent to which horses generalize between different visual objects, 2-year-old stallions were habituated to feeding from a container placed inside a test arena and assigned as TEST (n=12) or REFERENCE...
Does drinking milk stimulate sucking in young calves?
Contributor(s):: Passille, A. M. B. de, Metz, J. H. M., Mekking, P., Wiepkema, P. R.
To examine the motivation of non-nutritive sucking by calves, a series of tests was conducted on calves that were fed milk replacer by bucket and allowed to suck on a dry artificial teat. After the morning and afternoon meals, the calves sucked the teat for 4-6 min while they sucked it for less...
Does environmental enrichment consisting of brushing prepartum zebu heifers improve first-lactation behavior?

Does water or blowing air stimulate cows to defecate?
Contributor(s):: Robichaud, Marianne Villettaz, de Passillé, Anne Marie, Rushen, Jeffrey
Manure is an important cause of dirtiness and disease for cows and can affect milk quality and human health. The aim of this study was to test whether we could stimulate cows to defecate at a particular location in order to reduce the spread of manure. A series of four tests with 12 lactating...
Early human handling in non-weaned piglets: effects on behaviour and body weight
Contributor(s):: Oliveira, D. de, Costa, M. J. R. P. da, Zupan, M., Rehn, T., Keeling, L. J.
Early handling of animals including tactile stimulation (TS) has been shown to have beneficial effects on the physical and psychological development of species where considerable maternal interaction, e.g. in the form of licking, already occurs. But little is known about the magnitude of these...
Effect of enclosure quality on reactivity and welfare of captive Soemmerring's gazelle ( Gazella soemmerringii )
Contributor(s):: Mansour, A. A. H., Zakaria, A. H., Fraser, A. F.
The welfare of nonhuman animals in zoos is a great challenge to the zookeeper. Changes in the behavioral response of captive animals to their immediate environment can be used as a method for evaluating their welfare status. This study evaluates reactive responses of 3 groups of captive...
Effects of Calf Horn as Chews on the Behavior of Laboratory Dogs
Contributor(s):: Ketter, Daphne A., Klima, André, Küchenhoff, Helmut, Dobenecker, Britta, Schmidt, Jörg, Erhard, Michael H., Döring, Dorothea
It is increasingly required that non-human animals in laboratories are provided with adequate enrichment to promote the welfare of the animals. In a previous publication we showed that laboratory dogs intensively used the horn of calf hooves as chewing objects. In this report, we describe the...
