Positive reinforcement training as enrichment for singly housed rhesus macaques ( Macaca mulatta )
Contributor(s):: Baker, K. C., Bloomsmith, M. A., Neu, K., Griffis, C., Maloney, M.
Positive reinforcement training is one component of behavioural management employed to improve psychological well-being. There has been regulatory promotion to compensate for restricted social housing in part by providing human interaction to singly caged primates, implying an efficacy standard...

Pre-weaning environmental enrichment increases piglets' object play behaviour on a large scale commercial pig farm
Contributor(s):: Yang, Chung-Hsuan, Ko, Heng-Lun, Salazar, Laura C., Llonch, Lourdes, Manteca, Xavier, Camerlink, Irene, Llonch, Pol
Environmental enrichment is a legal requirement for European pig farms. The suitability of enrichment materials for neonatal pigs is understudied and has not been tested in commercial settings. This study investigates the effect of hanging objects and substrate as two enrichment strategies...

Preference and motivation for different diet forms and their effect on motivation for a foraging enrichment in captive Orange-winged Amazon parrots (Amazona amazonica)
Contributor(s):: Rozek, Jessica C., Millam, James R.
Motivation tests were conducted to assess preference strength for diet form and a cage enrichment device by Orange-winged Amazon parrots (Amazona amazonica) held in individual cages, N=10. Each cage was equipped with two trough-type feeders, one of which had a hinged lid that required lifting to...

Preferences for toy types and presentations in kennel housed dogs
Contributor(s):: Pullen, A. J., Merrill, R. J. N., Bradshaw, J. W. S.
Toys are often provided for adult dogs housed in kennels, but their effectiveness as environmental enrichment is not well documented. At a minimum, toys need to elicit interest in the animal for which they are intended, before any "enrichment" can be claimed. In this study we have examined...

Preferences of Orange-winged Amazon parrots ( Amazona amazonica ) for cage enrichment devices
Contributor(s):: Kim, L. C., Garner, J. P., Millam, J. R.
Cage enrichment devices (ED), frequently termed cage "toys", are often provided to captive parrots as a means of promoting a behaviorally stimulating environment, but it is not clear whether particular properties of EDs are more effective than others in eliciting engagement with them. We tested...

Providing ‘get-away bunks’ and other enrichments to primiparous adult female mink improves their reproductive productivity
Contributor(s):: Buob, Misha, Meagher, Rebecca, Dawson, Lauren, Palme, Rupert, Haley, Derek, Mason, Georgia
This study investigated whether simple, cheap enrichments – ‘get-away bunks’ (a wire mesh semi-cylinder attached to the cage ceiling) and small manipulable objects (balls and suspended chewing items) – could improve welfare and productivity in nursing mink dams (Neovison vison) in commercial farm...

Provision of a resource package reduces feather pecking and improves ranging distribution on free-range layer farms
Contributor(s):: Pettersson, Isabelle C., Weeks, Claire A., Nicol, Christine J.
The effect of a resource package designed to reduce inter-bird pecking and increase range use was tested on fourteen free-range farms in the UK. The package comprised two types of objects intended to attract pecking behaviour: ‘pecking pans’ containing a particulate pecking block, and wind...

Provisioning of live black soldier fly larvae (Hermetia illucens) benefits broiler activity and leg health in a frequency- and dose-dependent manner
Contributor(s):: Ipema, Allyson F., Gerrits, Walter J. J., Bokkers, Eddie A. M., Kemp, Bas, Bolhuis, J. Elizabeth
Fast-growing broilers spend most their time inactive and are therefore prone to experience leg problems. Environmental enrichment that facilitates intrinsically motivated behaviours can potentially promote activity and reduce leg problems, thereby improving broiler welfare. A promising...

Quantitative evaluation of the motivation to access a running wheel or a water bath in farm mink
Contributor(s):: Hansen, S. W., Jensen, M. B.
The purpose of the series of experiments presented here was to quantify the priorities of mink for swimming water and running wheel, respectively, by construction of demand functions for each of the two resources by use of operant conditioning techniques. In all the experiments, the mink were...

Rabbit preference for cages and pens with or without mirrors
| Contributor(s):: Zotte, A. D., Princz, Z., Matics, Z., Gerencser, Z., Metzger, S., Szendro, Z.
Five-week-old Pannon White rabbits were housed in a closed climatized rabbitry and randomly assigned to either pens (56 rabbits) having a basic area of 1 m2 with a stocking density of 16 and 12 rabbits/m2 or to 18 individual cages (0.24 m2/cage). The pens and the cages were divided into two...

Reaching new heights: the effect of an environmentally enhanced outdoor enclosure on Gibbons in a zoo setting
| Contributor(s):: Anderson, M. R.
Gibbons have adapted to live in the canopy layer of the rainforest. Gibbons in the wild predominantly spend their time high in the trees resting, traveling, and foraging for food. Comparatively, gibbons in the zoo often rest and search for their food terrestrially. The purpose of this study was...

Refuge use affects daily activity patterns in female Xenopus laevis
| Contributor(s):: Archard, Gabrielle A.
The African clawed frog (Xenopus laevis) is widely used for scientific research, but its ecology and behavior are poorly understood. In two experiments, the 24h activity patterns of female X. laevis were monitored. In the first, activity was determined both in the presence and absence of a...

Relative value of a nest box, sand floor and extra space during the breeding season in adult blue fox males
| Contributor(s):: Koistinen, T., Jauhiainen, L., Korhonen, H. T.
We measured how much adult blue fox males value access to a nest box and sand floor enrichments while a platform and activity object are available simultaneously. Ten blue fox males were solitary housed in test apparatuses with permanent access to a platform and wooden block (activity object)...

Responses of adult laying hens to abstract video images presented repeatedly outside the home cage
| Contributor(s):: Clarke, C. H., Jones, R. B.
In Experiment 1, individually housed, 31-week-old laying hens (n=45) were exposed to either the video image of a computer screensaver (SS) programme (Fish), a blank but illuminated television monitor (B), or a black plastic hide (H) presented approximately 50 cm in front of their home cages for...
