Among animal models, the pig is particularly relevant owing to its anatomical similarity to humans, although specific differences in the zygomatic arch and mandibular fossa require adapted surgical approaches. We describe and validate a standardized surgical approach to the porcine temporomandibular joint (TMJ) suitable for translational research. Eleven cadavers of Sus scrofa domestica were dissected to identify key anatomical structures. A high condylectomy was performed to establish a reproducible surgical pathway, and the caudal intra-articular injection technique was tested using methylene blue to assess its feasibility. The pig's TMJ area consists of superficial muscles such as the platysma and parotidoauricularis, with deeper structures such as the parotid gland, facial nerve and major vessels, while the bony anatomy includes a large condylar head and a superficial zygomatic arch. The proposed surgical approach to the pig TMJ involves a retromandibular incision with preauricular extension, subperiostal dissection to expose the zygomatic arch and articular capsule, followed by an incision to access the condyle, disc and mandibular fossa, allowing for condylectomy with careful preservation of the facial nerve and surrounding structures. This study highlights the anatomical differences with humans, such as the presence of the parotidoauricularis muscle, which lies superficially to the facial nerve and serves as a useful landmark for a safe dissection. The described approach provides a reliable and reproducible technique for future TMJ surgical studies in the pig model.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772261441431"},"PeriodicalIF":1.3,"publicationDate":"2026-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148317944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a need for practical methods of food restriction compatible with group housing. The diet board was developed as a mechanical solution to food restriction of group-housed rats. It tightly embeds food pellets in grooves cut into aspen boards, forcing the rats to gnaw wood to reach their food. In this two-year experiment, 146 nine-week-old outbred Hsd:Sprague Dawley® rats were divided into four equal groups: diet board-fed males and females, and ad libitum-fed males and females. Blood samples for clinical chemistry were collected at regular intervals during the study, and times of spontaneous death or euthanasia were recorded. Triglyceride and cholesterol values were significantly lower in diet board males than ad libitum males. The restriction of food intake via a diet board significantly increased the 24-month survival rate for both female and male groups. The better observed survival rates amongst diet board-fed rats makes it possible to start long-term studies with far fewer rats than with ad libitum feeding. Thus, using a diet board appears to be a promising method for the reduction of animal numbers in long-term rat studies that is compatible with group housing.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772261453481"},"PeriodicalIF":1.3,"publicationDate":"2026-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148277879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study aimed to highlight the importance of humane endpoints in a rat model of mammary carcinogenesis undergoing ladder resistance training to evaluate and ensure the absence of animal suffering. Twenty-eight female Wistar rats were assigned randomly to four groups of seven animals per group: sedentary, sedentary induced (with N-methyl-N-nitrosourea (MNU)), exercised and exercised MNU-induced. At 7 weeks of age, the animals in the induced groups were injected intraperitoneally (i.p.) with the carcinogenic agent (N-methyl-N-nitrosourea; i.p; 50 mg/kg). The animals' welfare was monitored using a set of biological characteristics. The resistance exercise training, started at 9 weeks old and comprised climbing a ladder three times per week for 18 weeks, gradually increasing the load throughout the protocol. Of 14 MNU-induced rats, 9 (64%) developed mammary cancer. Exercised rats tended to show delayed tumor ulceration despite larger tumor volumes. No significant differences in bodyweight were observed, although weight loss appeared earlier in sedentary-induced animals. Exercised rats exhibited more stress signs, including reduced grooming and one case of chromodachryorrhea, yet had lower tumor-related humane endpoint scores. Three rats were euthanised early due to tumor-related endpoints. Minor tail wounds occurred but did not affect exercise or welfare. These results indicate that, with careful endpoint monitoring, the exercise protocol is well tolerated and may improve performance in tumour-bearing rats, supporting ethical standards while allowing accurate investigation of resistance training effects.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772261444916"},"PeriodicalIF":1.3,"publicationDate":"2026-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148252050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

As such, any effort to advance the 3Rs must engage with this complexity and incorporate the lived experiences of stakeholders to inform policy advancements. In an interview-based study, we gathered insights from 35 Swiss researchers on the implementation of the 3Rs in Switzerland. Using reflexive thematic analysis, we identified two overarching categories of facilitation: originative facilitation, referring to the collective meaning-making of the 3Rs, and executive facilitation, encompassing politico-institutional conditions that support their implementation. The present paper focusses on the latter domain, in which key themes include political support fostering a pro-3R research environment, the cultivation of a 3R culture within research institutions, clearer 3R guidance from cantonal commissions on animal experimentation, and strategic use of the Swiss 3R Competence Centre as a leading national 3R intermediary. These themes detail major institutional stakeholders that could further promote the implementation of the 3Rs from the perspective of researchers. Accordingly, the results showed that advancing the 3Rs is not just a matter of niche innovations but should also be orchestrated from a broader institutional perspective and with specific objectives to achieve. While these findings are specific to the Swiss context, they provide valuable information for countries with similar regulations on animal experimentation or a similar political structure.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772261447418"},"PeriodicalIF":1.3,"publicationDate":"2026-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148252081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Pain and distress are generally considered in the context of the analogy postulate and the precautionary principle. The analogy postulate refers to (patho-)physiological similarities between humans and vertebrates, assuming that manipulations causing pain and distress in humans do so equally in vertebrates. According to the precautionary principle, animals will be considered to have pain/distress in the absence of any scientific consensus as to the presence or absence of pain. Although those principles can be useful guides for humane treatment of laboratory animals, they do not address the subjectivity involved in recognising pain/distress. A reliable estimate of animal pain and distress can be derived from both behavioural and physiological indicators. Distress and pain are biological phenomena that motivate behaviours aimed at alleviating these states. If no behaviour achieves the expected outcome, the animal may switch to other modes, such as depression or learned helplessness. Pain is regarded as a biologically adaptive mechanism, alerting organisms to possible damage or injury. The effect of experimental procedures on perceived pain/distress may depend on physical and social environmental conditions. Observation schemes can be used to assess and monitor daily for clinical signs or problems. They can help reduce pain/distress and provide adequate care. Competent observation of animals is also basic to the correct implementation of humane endpoints. AI will transform research. Intelligent systems will generate data, enable early stress detection and improve animal welfare.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772261446785"},"PeriodicalIF":1.3,"publicationDate":"2026-06-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148252079","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these issues, it is crucial to systematically identify the psychological and emotional burdens, as well as the specific stressors, experienced by individuals in this field. This study examines the ethical conflicts and compassion fatigue encountered by personnel working with laboratory animals in Korea. An online survey was conducted with 165 participants, including animal researchers (laboratory technicians, postdoctoral researchers, and graduate students), principal investigators, animal facility managers, and attending veterinarians. The results indicated that animal researchers experienced lower levels of stress and fewer ethical dilemmas than other occupational groups, including principal investigators, attending veterinarians, and animal facility managers. Female respondents reported a higher frequency of ethical dilemmas than male respondents, regardless of occupational role. Participants with less than six years of work experience reported fewer ethical dilemmas than those with longer tenure, suggesting that ethical sensitivity might increase with prolonged exposure to animal experimentation. Euthanasia and animal pain were identified as the primary sources of ethical stress. Multivariate logistic regression analysis revealed that experiences of ethical dilemmas, years of employment, and occupational role were significantly associated with stress levels. These findings underscore the need for organizational-level interventions to mitigate ethical stress and promote a healthier research environment. Strengthening emotional resilience and supporting the overall well-being of personnel working with laboratory animals are essential goals of such efforts.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"236772261443573"},"PeriodicalIF":1.3,"publicationDate":"2026-06-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148211834","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main aim of this study was to gain a better understanding of the importance of access to sheltered space for laboratory mice. We pair-housed mice (BALB/c, SWISS and C57BL/6, male and female) in conventional laboratory cages that contained either (i) resources to build underground shelter (burrowing substrate) or (ii) artificial structures providing shelter (e.g. red plastic house). We assessed how mice used these resources, as well as their preferences when given a choice between different shelters. In addition, we assessed the insulating properties of different shelters. Mice spent most of their time underground in deep bedding and the least time inside the standard red plastic house, where they nested outside the house. They also showed a strong preference for the deep burrow cage, and the most relevant features of preferred shelters seem to be darkness and being underground. Nesting material alone was also less insulating, possibly contributing to an increased need for non-shivering thermogenesis.","PeriodicalId":18013,"journal":{"name":"Laboratory Animals","volume":" ","pages":"247-257"},"PeriodicalIF":1.3,"publicationDate":"2026-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147633905","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
