Using longitudinal data to evaluate the behavioural impact of a switch to carcass feeding on an Asiatic lion (Panthera leo persica) (Finch et al., 2020)
What is the long-term behavioural impact of carcass feeding on zoo-housed Asiatic lions? A lioness at Chester Zoo showed the following behavioural changes 12 months after the diet change: ✔Reduction in pacing; ✔Increase in resting behaviour; ✔Increase in feeding-related behaviours, shortly after & 12 months after the diet change.
Longitudinal Improvements in Zoo-Housed Elephant Welfare: A Case Study at ZSL Whipsnade Zoo
(Finch et al., 2020)
New study assessed the welfare improvements of the Asian elephants at ZSL Whipsnade Zoo, using data from their species-specific behavioural monitoring programme. Some of their findings include: ✔Species-appropriate levels of feeding; ✔Low levels of stereotypic behaviours; ✔Rare agonistic behaviour between group members; ✔Positive social associations & interactions between group members.
Specialised for the Swamp, Catered for in Captivity? A Cross-Institutional Evaluation of Captive Husbandry for Two Species of Lechwe (Rose & Rowden, 2020)
There is a new published paper on zoo husbandry practices in lechwe - a wetlands social antelope that is understudied in captivity: ✔Similar male:female ratios in captive and wild herds; ✔Enclosures usually included wetland areas, which were rarely managed; ✔Vegetation cover was limited; ✔Similar diets between zoos, but different from guidelines; ✔Abnormal behaviours reported but causes not identified.
A Retrospective Study of Macropod Progressive Periodontal Disease (“Lumpy Jaw”) in Captive Macropods across Australia and Europe: Using Data from the Past to Inform Future Macropod Management (Rendle et al., 2020)
New research looked into "lumpy jaw" disease in captive macropods: ✔High mortality (62.5% for Australian & European institutions); ✔Risk of developing the disease increased with age; ✔Different incidence rates & risk of infection between institutions and geographic regions; ✔Recommendations to reduce disease risk were provided.
A persistent abnormal repetitive behaviour in a false water cobra (Hydrodynastes gigas) (Michaels et al., 2020)
Fresh new paper looked into stereotypic behaviour in captive false water cobras: ✔Observed fixed pattern of movement against viewing window identified as potential stereotypy; ✔Snake spent some time in this repetitive behaviour, which was also reported by another zoo; ✔The enrichment used did not reduce the behaviour's frequency or changed the snakes' use of the enclosure.
The 2020 Five Domains Model: Including Human–Animal Interactions in Assessments of Animal Welfare (Mellor et al., 2020)
The Five Domains Model of animal welfare assessment has just been updated in a new paper: ✔Five Domains: (1) Nutrition, (2) Physical Environment, (3) Health, (4) Behavioural Interactions, (5) Mental State; ✔Update adds human-animal interactions to the model; ✔Applicable to all animal caretakers, including zoo keepers, researchers & veterinary staff!
Seasonal and Daily Activity of Two Zoo-Housed Grizzly Bears (Ursus arctos horribilis)
New study investigated activity patterns in two zoo-housed grizzly bears: ✔Most inactivity recorded in winter; ✔Stereotypies and general activity emerged in spring and summer; ✔Stereotypies more frequent in the morning.
