Special Issue Information

Dear Colleagues,

Globally, there are billions of domestic animals being raised for food production, kept as pets or for research, testing and teaching, used in sporting events or other types of entertainment, or in other systems where they are dependent on human management. As you know, interest in how the welfare of these animals can be better understood and protected has significantly increased in recent years and is continuing to do so. As this interest increases, interest in finding innovate and scientifically robust methods for assessing animal welfare continues.

There are several challenges associated with assessing animal welfare, including the invasive nature of some measures and techniques we use and the differences in physiological and behavioural thresholds to wild counterparts or between different breeds. In addition, animal welfare assessment is inherently an activity of indirect measurement that often requires significant time and resources impractical for use in many scenarios. Therefore, there is an ongoing need for innovative methods for assessing the welfare of domestic animals that are practical to use and adaptable to many species in a range of scenarios, using novel measures of welfare and emerging technology.

This Special Issue will focus on recent research or reviews that investigate innovative approaches and/or technologies used to assess the welfare of domestic animals.

The environmental enrichment needs of snakes are often disregarded. Using preference testing, we aimed to shed light on the enrichment preferences of a popular pet species, the western hognose snake (Heterodon nasicus). Snakes’ enclosures were divided into enriched and standard sides. The enriched half had substrate for burrowing, interactive stimuli, and a large water dish. The standard half had paper towel substrate and a small water dish. Each side also contained a single shelter. We provided belly heat to create a thermal gradient on one side of the cage. Snakes were observed for 6 days, four times daily. We predicted a preference for enriched conditions and, as snakes are ectothermic, a preference for the warmer side. Snakes were additionally given an exploration assay, to explore whether differences in preference for environmental enrichment interact with boldness levels. We found that hognose snakes preferred enrichment, and the strength of this preference increased over time. Preference for enrichment was stronger when the enriched side was cooler. This may be due to the burrowing tendencies of these snakes. We found no relationship between preference and boldness. These findings emphasise the importance of preference testing in establishing research-informed enrichment opportunities for reptiles. Full article
