Home cage aggression in group-housed male mice is a major welfare concern and may compromise animal research. Conventional cages prevent flight or retreat from sight, increasing the risk that agonistic encounters will result in injury...
Depression is a human mental disorder that can also be inferred in non-human animals. This study explored whether time spent inactive but awake (“IBA”) in the home-cage in mice was further triggered by risk factors...
Although there has been an increase in research studying the impact of housing on zoo animal welfare, there is still a lack of literature regarding the impact of seasonal housing differences on animal welfare. In...
Many indoor-housed cows isolate at calving when given the opportunity, and calving behaviors vary by blind and pen design. The objectives of this study were to determine if cows preferred calving in a visibly separated...
The public has expressed growing concern for the well-being of fishes, including popular pet species such as the Siamese fighting fish (Betta splendens). In captivity, male Bettas behave aggressively, often causing injuries and death if...
IntelliCage for mice is a rodent home-cage equipped with four corner structures harboring symmetrical double panels for operant conditioning at each of the two sides, either by reward (access to water) or by aversion (non-painful...
Stalls or crates are a very common type of housing used on pig farms that restrict an animal’s movement. How this confinement impacts the animal’s affective states is seldom investigated. We conducted a preference test...
Laboratory fish play an important role in many research fields, and they are also raised and bred in many laboratories around the world. While many studies have suggested suitable feeding densities for various laboratory fish...
Intensification and complexity of pig production systems may require different strategies for animal welfare improvement. We aimed to identify welfare issues of gestation sows and areas for improvement by comparing four production systems, including the...
Sleep is an important contributor to good physical and mental health and an important component of post-surgical recovery. The assessment of dark phase (‘nighttime’) behavior can provide insight into the efficacy of analgesic treatments and...
