The electrical method achieved a complete state of unconsciousness 7 minutes faster than air asphyxiation. Our results show that air asphyxiation raised cortisol levels more than the electrical method, with no significant difference in glucose and lactate concentrations. Electrically treated fish had higher superoxide dismutase and liver-reduced glutathione levels, while suffocated fish showed elevated GSH and liver catalase levels. Radiographs revealed no fractures or skeletal changes. Electrical stunning had no effect on gill tissue, but caused brain tissue hemorrhage, whereas air asphyxiation caused less damage. Air asphyxiation caused gill tissue issues but less brain damage. Consciousness loss is crucial for humane practices.

Dogs were filmed moving on a loose lead over a Tekscan Strideway gait analysis system. Stride length as a proportion of limb length (calculated as distance from the elbow to the floor), body weight distribution in the front versus the hind limbs (%), and minimum and maximum apparent angles of the lateral epicondyle of humerus (LEH) and greater tubercle of humerus (GTH) during the motion cycle were measured. Except for GTH angles, there were significant differences in all the investigated metrics. Differences varied across breeds/breed types. It is recommended that, when purchasing and fitting harnesses for dogs, owners and harness fitters treat dogs on an individual basis. The impact of pulling in harness on dog gait requires investigation as dogs may experience greater restrictions when pulling than during locomotion on a loose lead.","PeriodicalId":56277,"journal":{"name":"Journal of Applied Animal Welfare Science","volume":" ","pages":"301-317"},"PeriodicalIF":1.4,"publicationDate":"2025-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41162911","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In two of these cases, we analyzed the dams' and kits' behavior during the first week after the fostering event and recorded the kits' weight. Three fostering events were successful, with foster kits surviving until weaning age; two were unsuccessful, possibly due to the age and developmental stage difference between foster and biological kits. Behaviorally, dams appeared to care for all kits equally, without differences observed in average maternal behaviors or aggression between dams and kits, or among kits. Despite the weight being difference between foster and biological kits, we have verified that fostering can be successful in this species. Future fostering attempts should complement behavioral observations with physiological parameters to assess effects on growth and survival and match foster kits with similarly aged litters to maximize chances of acceptance.","PeriodicalId":56277,"journal":{"name":"Journal of Applied Animal Welfare Science","volume":" ","pages":"1-11"},"PeriodicalIF":1.4,"publicationDate":"2025-03-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143733277","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The NaCl treatment significantly reduced cortisol levels and the expression of HSP70, HSP90, GR, and MR (p < 0.05).

Qualitative Behavioral Assessment (QBA) is a promising alternative to ethograms. This study evaluated QBA's usefulness in assessing behavior in ten captive black rhinos in a UK zoo by comparing it with ethogram data. QBA descriptors meaningfully overlapped with ethogram behaviors, for example, agonistic behaviors like horn clash aligned with Angry, Startled, and Nervous, while playful behaviors like head fling matched Lively and Excited. Correlations emerged between techniques; for instance, naso-nasal greeting and environmental investigation correlated with Active and Interested, while tactile contact negatively correlated with Angry and Nervous. Individual rhinos accounted for ~35% of (co)variation, with coefficient plots identifying significant key ethogram behaviors/QBA descriptors. The strong overlap within a joint model suggests QBA is a valuable welfare assessment tool that complements ethogram data collection for this species.","PeriodicalId":56277,"journal":{"name":"Journal of Applied Animal Welfare Science","volume":" ","pages":"1-16"},"PeriodicalIF":1.4,"publicationDate":"2025-03-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143694155","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The time of day and the number of times bell-ringing behavior occurred were recorded. Additionally, we recorded human presence, and whether humans were zoo staff or visitors. Observations were made over a 6-month period, starting 4 months after the objects were placed without food. Bell-ringing behavior occurred regardless of the humans present, who were categorized into four groups based on their roles. The behavior tended to be expressed more in the afternoon than in the morning, with no strong relationship observed with daily feeding times.
