People believe that naturalistic enclosures make animals happier
Vervaecke, Hilde ; Stevens, Jeroen ; D'haen, Sarah ; Arnouts, Heidi
Zoo enclosure designers should aim to offer behavioural opportunities that allow animals to enhance their quality of life. This can be achieved through a “behavioural engineering approach” in which artificial devices can be used, or through the “naturalistic approach” in which the wild environment is mimicked maximally. We hypothesized that the visitors’ perception of the animals’ happiness or wellbeing is influenced by enclosure design. In an online query, we showed pictures of natural versus unnatural looking enclosures for bonobos and we asked to score happiness on a 7-point scale, following an existing 4 item questionnaire, used to score subjective wellbeing in apes. A linear mixed model was applied with individual score as response value, respondent ID as random effect and enclosure type (natural or unnatural) as fixed effect. Respondents gave a significantly higher happiness score to more natural enclosures (df=1, p< /0.0001). In more natural enclosures, they thought the bonobos would experience positive emotions during a longer period (df=1; p< /0.0001), they gave a higher score to the degree in which they estimated the animals to be successful at fulfilling their needs (df=1; df=0.0001), and they thought they themselves would be happier if they were the animal during one week in that enclosure (df=1, p< /0.0001). For each of the four questions, all nine pairwise comparisons of natural versus unnatural enclosures showed that the differences were significant (df=200, p< /0.00001) for happiness score, duration of happiness, and happiness if the respondent would be the animal. Similarly, all pairwise comparisons differed significantly for ‘efficiency to fulfil their needs’, except for the comparison of the pictures of a natural but relatively empty grassy area and an unnatural indoor enclosure with climbing structures (df=200, p< /0.351), indicating a rough understanding of great apes’ climbing needs. Overall, people feel that naturalistic looking enclosures make bonobos happier. Whether their behavioural and psychological needs are met more efficiently in naturalistic enclosures needs to be assessed separately.

Behaviour of horses during hoof trimming: do they behave more calmly with adhesive tape on the nose?
Vervaecke, Hilde ; Pypaert, Ine ; Muelherr, Jeanine ; Arnouts, Heidi
The “duct tape twitch” – a piece of adhesive tape stuck on the vertical midline of the horses’ nose – is supposed to calm horses down during hoof trimming. The underlying mechanism is unknown. We tested the effect of this tape on 30 horses, with three farriers. For each horse, trimming of one forefoot and one hindfoot was observed with and without tape on the nose, in a randomized order. Relaxed and tensed behaviours were scored during five minutes per hoof for a total of 20 minutes per horse. In one horse the experiment was terminated due to dangerous behaviours. A mixed linear model was used to examine the relationship between relaxed and tensed behaviour and presence of tape. Besides horse identity, identity of farrier, sex (male - stallion or gelding - and female), judgment of owner about calmness of horse (calm, not calm), type of hoof manipulation (lifting, rasping, cutting, clipping), the model also included other factors possibly explaining part of the variance. Mares were more relaxed (p< /0.04), there was more relaxed behaviour during rasping compared to lifting, cutting and clipping (p< /0.0001) and the horses showed significantly more relaxed behaviour with tape on the nose (p< /0.0001). We saw more tensed behaviour in horses that were judged by the owner as “not calm” (p< /0.0001). The horses showed more tensed behaviours during foot lifting and when they had no tape on the nose (p< /0.0001). The increase in relaxed behaviours and decrease of tensed behaviours when there was tape on the nose was significant but small (p< /0.0001). Horse and farrier identity also affected tensed behaviours. The application of tape slightly calms down horses but its’ application or attempts hereto can in some cases cause dangerous reactions.
