Quality Management and Animal Welfare as Culture of Care for Animal Experiments under Biosafety Level-3, taking COVID-19 as a Practical Example

Abstract Since the start of the COVID‐19 pandemic, a tremendous amount of work has been done by scientists to understand the pathogenesis of the severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2). Several animal models have been reported to be useful for the development and testing of vaccines, antivirals, or therapeutics. These in vivo experiments have to be performed at high containment biosafety level (BSL)-3. Thus, an appropriate biosafety, facility and data management as well as high standard of animal welfare, thorough study design, and staff training combined with an overall research transparency and open communication need to be implemented to achieve high quality reproducible research. Such an approach combined with the well-known 3R principle (Replacement, Reduction, and Refinement) and the 3S principle (Good Science, Good Sense, and Good Sensibilities) can contribute to culture of care in scientific research. The perspective reviews the key points of optimized biosafety, data, quality and animal welfare management in high risk biosafety-settings to conduct animal experiments with infectious pathogens in the context of a culture of care.

Comparison of animal welfare assessment tools and methodologies: need for an effective approach for captive elephants in Asia.

Welfare is a fundamental aspect of animal management and conservation. In light of growing public awareness and welfare concerns about captive elephants, there is an urgent need for comprehensive, globally coordinated efforts for Asian elephants (Elephas maximus) that participate in religious, logging, or tourist activities in range countries where the majority reside, and where welfare issues have been identified but not addressed. This review provides a comparative analysis of available animal assessment tools. Each offers distinct features for assessment that allow institutions to select criteria for specific needs and available resources. Most are applied to general animal welfare assessments, although some are tailored to particular species, including elephants. The tools span diverse formats, from digital to primarily paper-based assessments. Assessments operate at individual and institutional levels and across multiple welfare domains. Methodologies rely on keeper ratings or expert evaluations, incorporate numerical scoring and Likert scales for welfare grading, and encompass inputs including behaviors, health, and physiological indicators. For tourist camp elephants, one challenge is that the tools were developed in zoos, which may or may not have application to non-zoological settings. Digital tools and assessment methodologies such as keeper ratings face logistical challenges when applied across tourist venues. As with any tool, reliability, validity, and repeatability are essential and must address the unique welfare challenges of diverse captive settings. We propose that a holistic, context-specific, evidence-based, and practical tool be developed to ensure high elephant welfare standards in non-zoological facilities throughout Asia.

Overpopulation of Animals in India: Analyzing Legislative Shortcomings

The overpopulation of animals in India is a critical issue with far-reaching consequences, impacting animal welfare, public health, and community safety. This legal research paper examines the root causes of this problem and the inadequacies in India's current legislative framework governing animal welfare. It explores how vague language, lax enforcement, and gaps in coverage have contributed to the unchecked growth of stray animal populations, resulting in suffering, public health risks, and safety concerns. Comparative analysis with regions known for effective animal welfare legislation reveals best practices and strategies that can be adapted to the Indian context. The paper proposes a series of legal reforms tailored to the Indian context, including mandatory spaying and neutering, comprehensive registration and microchipping, stricter licensing and breeding regulations, public education and awareness campaigns, strengthened animal cruelty penalties, and the introduction of Trap-Neuter-Return (TNR) programs for feral animals. Addressing challenges, objections, and ethical considerations, these recommendations aim to strike a balance between personal freedoms and the need for responsible pet ownership. Through case studies and a contextualized approach, this research underscores the importance of addressing legislative shortcomings in India to safeguard animal welfare, protect public health, and ensure community safety. The proposed reforms seek to harmonize India's rich cultural diversity with modern animal welfare standards, ultimately creating a more compassionate and secure environment for both animals and humans in the Indian context.

A Retrospective Study on the Status of Working Equids Admitted to an Equine Clinic in Cairo: Disease Prevalence and Associations between Physical Parameters and Outcome.

Working equids are often used to exhaustion, living and dying in conditions below minimal welfare standards. Due to their poor welfare status, euthanasia should be considered in certain conditions. The study aimed to describe the population and the disease frequency of the working equids admitted at an equine clinic in Cairo (i.e., Egypt Equine Aid (EEA)) from 2019 to 2022 and identify possible associations between physical parameters at admission and the outcome. Records of 1360 equids admitted at EEA were reviewed. The majority of the admitted equids were horses (65.6%), followed by donkeys (33%), in particular stallions (68.7%), from 1 to 15 years old (74.8%). Hospitalisation was mainly due to wounds (28.9%), orthopaedic problems (27.4%), colic (8.5%), or infectious diseases (7.4%). The majority of the equids were discharged, but 5.1% died on their own, without human intervention, and 23% were euthanised. Text mining revealed the anamnesis's most frequent words were 'accident', 'lameness', and 'wound'. In addition, owners sometimes reported using inappropriate remedies (e.g., firing) before hospitalisation. Multivariable ordinal regression analysis performed between physical parameters and the outcome (ordered based on severity: discharged, euthanasia, and dead) revealed that sex (male vs. female: OR = 1.33; p < 0.05), colour of the mucous membrane (pathological vs. physiological: OR = 1.72; p < 0.01), and capillary refill time (pathological vs. physiological: OR = 1.42; p = 0.02) increased the likelihood of a non-survival outcome. In conclusion, early euthanasia should be considered for these equids, to minimise prolonged suffering. Moreover, owners' education is recommended to guarantee minimal welfare standards to the working equids.

Forced Handling Decreases Emotionality but Does Not Improve Young Horses' Responses toward Humans and their Adaptability to Stress.

Horses are often still exposed to stressful or inadequate conditions and difficult relationships with humans, despite growing concerns about animal welfare. In the present study, we investigated the impact of different approaches of short-term handling sessions on young Lusitanian horses raised on a high-breed farm, specifically on their later adaptability to humans and stressful environments. Thirty-one foals (3 months old ± 15 days), from both sexes, were separated into three groups, one submitted to 3 consecutive days of handling sessions (Int-H), another to one handling session each month for 3 months (Month-H), and one left undisturbed (control). At 8 months old ± 15 days, all foals were evaluated during behavioral tests (restraint in a stock and forced-person test). Evaluations were based on behavioral observations and physiological assessments. The handled foals (Int-H and Month-H) reacted less to being isolated and restrained and better tolerated human contact and veterinary procedures than the control ones. The handled foals displayed less evasive and negative behaviors toward human approach, but also sought less human contact and did not interact, regardless of the handling timeframe. All animals displayed signs of stress when restrained in the stock, with increased neutrophil counts and CHCM levels in the blood, and no differences in metabolic (CK and LDH) and other hematological parameters. The neutrophil-lymphocyte ratio was significantly higher (p < 0.05) in handled foals than in control ones, suggesting low standards of welfare. Our data suggest that early forced handling decreases fearfulness in new environments; however, it does not improve the horses' relationship with humans, and it decreases welfare.

Cattle transporters' attitudes, indigenous knowledge, and current practices towards animal welfare, occupational well-being, and operational challenges: A survey of five regions in Ghana

Ghana is a significant cattle producer in Africa with an estimated cattle population of 3 million in 2020 [1]. The role of transporters in linking farms to markets and slaughterhouses is crucial in the livestock value chain. However, cattle transportation subjects the animals to high levels of stress, compromising their welfare, and transporters face challenges such as long working hours and harsh conditions.The objective of this study was to explore current practices, indigenous knowledge, and operational risks pertaining to animal welfare among transporters.The study was conducted in five regions connected by the N16, N10, and N6 Highway, the primary route for cattle transportation from the Ghana-Burkina Faso border to the coastal capital of Accra. A total of 78 transporters participated in the study.Out of the 78 participants in this study, the majority of transporters were young adults (56.5%) with secondary school education (45.9%) and 0–5 years of experience (37.2%). The average distance and time for transporting cattle was 528 km and 18 h, respectively. The transporters highlighted significant challenges encountered during cattle transport, including feed and water shortage, particularly prominent during the dry season (32.1%), as well as the occurrence of diseases and mortality, particularly high during the rainy season (41%). Furthermore, vehicular breakdowns were a common issue reported by transporters, with a substantial majority (88.5%) experiencing breakdowns during their last 10 trips. The results showed that most transporters (84.7%) had limited knowledge of animal welfare and had not received any formal education on livestock transportation. Instead, they gained experience as assistants on other trucks before becoming drivers. The findings of this study highlight the need for improved welfare standards for cattle during transportation and formal training programs for transporters in animal welfare and livestock transportation.

To trust or not to trust? Trust landscape of organic animal husbandry: Mapping consumer attitudes and information demands in Germany

A mainly positive attitude of consumers towards organic animal husbandry with its higher keeping standards compared to the legal regulations is evident. However, less is known about consumers’ detailed expectations of organic husbandry and in particular their attitude and trust along the value chain of organic animal products. Which consumers trust the most, and how do they want to be informed about organic animal husbandry? Where along the chain are trust deficits that should be addressed in the future to support sustainable food consumption with high animal welfare standards? To answer these important questions a survey was conducted among 729 German meat consumers. Using a cluster analysis, various consumer groups were identified based on their trust levels. Further, these groups were characterized regarding their general attitude, their information behavior, their evaluation of current media reporting, and their preferred way to be informed (emotional/rational) about organic animal products. The results revealed three clusters that clearly differ in their trust level of organic husbandry. Respondents assigned to the first cluster are committed organic consumers with high trust and the most positive attitude. The second cluster, combines respondents who are generally open to organic meat consumption and showing the second highest trust level and positive attitude towards organic. They show a slight favor for a more rational presentation of information. The third cluster is the smallest and can be described as the skeptics with a low interest in organic. The results indicate a general moderate to high trust level along the value chain of organic animal products, with the highest trust in organic retailers and farmers and the least trust in processing and conventional retailers. These are important insights for the organic sector in order to improve consumer trust and therewith increase the market share of organic meat products.

Dolphin-WET-Development of a Welfare Evaluation Tool for Bottlenose Dolphins (Tursiops truncatus) under Human Care.

Ensuring high standards of animal welfare is not only an ethical duty for zoos and aquariums, but it is also essential to achieve their conservation, education, and research goals. While for some species, animal welfare assessment frameworks are already in place, little has been done for marine animals under human care. Responding to this demand, the welfare committee of the European Association for Aquatic Mammals (EAAM) set up a group of experts on welfare science, cetacean biology, and zoo animal medicine across Europe. Their objective was to develop a comprehensive tool to evaluate the welfare of bottlenose dolphins (Tursiops truncatus), named Dolphin-WET. The tool encompasses 49 indicators that were either validated through peer review or management-based expertise. The first of its kind, the Dolphin-WET is a species-specific welfare assessment tool that provides a holistic approach to evaluating dolphin welfare. Inspired by Mellor's Five Domains Model and the Welfare Quality®, its hierarchical structure allows for detailed assessments from overall welfare down to specific indicators. Through combining 37 animal-based and 12 resource-based indicators that are evaluated based on a two- or three-level scoring, the protocol offers a detailed evaluation of individual dolphins. This approach allows for regular internal monitoring and targeted welfare management, enabling caretakers to address specific welfare concerns effectively.

Guidance on Minimum Standards for Canine-Assisted Psychotherapy in Adolescent Mental Health: Delphi Expert Consensus on Health, Safety, and Canine Welfare.

As interest in animal-assisted therapy (AAT) and canine-assisted psychotherapy (CAP) grows, there are increasing calls for the management of related health, safety, and welfare concerns for canines, providers, and clients. Existing health and safety guidelines lack empirical support and are, at times, contradictory. Welfare is increasingly prioritized; however, tools to monitor and manage welfare are underutilized and under-reported. The aim of this study was to provide expert consensus on the minimum health, safety, and welfare standards required to develop and deliver a CAP group program to adolescents experiencing common mental health disorders. Diverse AAT experts were recruited globally. Using Delphi methodology, over two rounds, 40 panelists reached a consensus agreement to include 32 items from a possible 49 into the minimum standards. Health and safety measures included risk assessment, veterinary screening, preventative medicine, training in infection control, and first aid. Welfare measures included training in welfare assessment, documentation of welfare, and flexible, individualized responses to promote wellbeing. Intestinal screening for parasites and the prohibition of raw food were not supported. Flexible and individualized assessment and management of canine welfare were supported over fixed and time-limited work schedules. Clinical practice implications are discussed, and recommendations are made.

Values Beyond “Health” in Budget-Constrained Healthcare Systems

ObjectivesMost current methods to value healthcare treatments only incorporate measures such as quality-adjusted life-years, combining gains in health-related quality of life and life expectancy in specific ways. Failure of these methods to recognize other dimensions of value has led to calls for methods to include additional values that are associated with the healthcare treatments but not captured directly by quality-adjusted life-years. This article seeks to provide methodologically sound ways to incorporate additional health-related outcomes, focusing on budget-constrained healthcare systems, in which using standard welfare economics methods are often eschewed. MethodsThe analysis develops standard extra-welfarist approaches to maximizing aggregate health, subject to fixed-budget constraints, using Lagrange multiplier methods. Then, additional valuable health-related outcomes, eg, reduced caregiver burden, real option value, and market- and non-market productivity are introduced. The article also introduces a social welfare function approach to illuminate how disability, disease severity and other equity-related issues can be incorporated into complete welfare measures. ResultsResulting analysis, fully developed in an Appendix in Supplemental Materials found at https://doi.org/10.1016/j.jval.2024.02.005 and summarized in the main text, show that understanding how average and marginal healthcare costs increase with output and how health augments “additional values” provides ways to assess willingness to pay for them in these fixed-budget situations. ConclusionsIn budget-constrained healthcare systems, only from actual budget allocations can values both of health itself and “additional values” be inferred. These methods, combined with methodologically sound social welfare functions, demonstrate how to move from “health” to “welfare” in measuring the value of increased healthcare use.

Mouse and Rat Anesthesia and Analgesia.

Anesthesia and analgesia play pivotal roles in ethically and humanely using animal models in research, especially concerning mice and rats. These rodent species, extensively utilized in scientific investigations due to their genetic resemblance to humans, serve as invaluable tools for studying diseases and testing treatments. Proper anesthesia and analgesia not only prioritize animal welfare but also heighten experimental validity by minimizing stress-induced physiological responses. Recent years have seen remarkable advancements in anesthesia for mice and rats. The focus has shifted away from the 'one size fits all' toward tailoring anesthesia protocols, considering factors like age, strain, and the nature of the experimental procedure. The use of inhalation agents such as isoflurane and sevoflurane is often preferred due to their rapid induction and recovery characteristics, allowing precise control over anesthesia depth. However, refinements in injectable anesthetic agents also provide researchers the flexibility to select suitable agents based on study requirements. Additionally, progress in analgesic techniques has led to effective pain management strategies for these rodents. Common analgesics such as nonsteroidal anti-inflammatory drugs (NSAIDs), opioids, and local anesthetics are administered to alleviate pain and discomfort. However, standard practice also involves continuous monitoring of animals' behavior and physiological parameters, ensuring timely adjustments in analgesic regimens for optimal pain relief without compromising experimental outcomes. By integrating tailored anesthesia and analgesia protocols into the experimental design, researchers uphold high animal welfare standards while obtaining reliable scientific data. This contributes significantly to advancing medical knowledge and therapeutic interventions with reproducible results. Published 2024.

Quantitative and Qualitative Evaluation of Plant Intake in Laying Hens: n-Alkanes as Predictive Fecal Markers for Dietary Composition Assessment

The shift in animal welfare standards towards free-range housing for laying hens in the EU has raised questions about changes in dietary composition. Accurate assessment of outdoor plant material intake is crucial for effective feeding strategies. This study introduces an approach using n-alkanes as markers to determine plant intake in laying hens, involving n-alkane recovery rate assessment, discriminant analysis and linear equation-solving for both qualitative and quantitative assessment, respectively, considering systematic n-alkane combinations. Two diets: a standard commercial diet and a diet incorporating 1% alfalfa were tested. Chemical analyses showed an altered n-alkane profile due to alfalfa inclusion, resulting a recovery rates ranging from 30–44% depending on the n-alkane type and diet. Statistical analysis revealed significant differences in recovery rates among the different alkanes for the same diets and between the diets for the same alkane, together with an interaction between n-alkane carbon chain length and initial concentration in the diet. The method accurately predicted plant inclusion, with a slight overestimation (2.80%) using the combination C25-C29-C33. Accurate qualitative classification of the animals based on fecal n-alkanes profiles was observed. The study successfully demonstrated the utility of n-alkanes for estimating dietary composition, providing a non-invasive approach for future free-range studies.

Commercial Egg Replacers in Pound Cake Systems: A Comprehensive Analysis of Market Trends and Application.

Replacing eggs without influencing pound cakes' texture, appearance, and taste is challenging. Ovalbumin, the major protein in egg white, contributes to the structures of cakes by providing SH Groups that form a firm gel during baking. However, there is a shift in the consumers' behaviour regarding health, well-being, animal welfare standards, and environmental concerns. To meet upcoming trends and consumer needs, 102 egg replacement products were launched globally to the best of the authors' knowledge, with 20 of them advertised as suitable for baking applications. Ten locally available commercial egg replacers with a range of protein contents were chosen and applied in a pound cake model system to evaluate their functionality by evaluating cake and cake batter quality. Three different categories of egg replacements were chosen: replacers containing no protein (R1-R3), a low amount of protein (1-10 g/100 g; R4-R5), and a high amount of protein (>10 g/100 g; R6-R10). Those were compared to three control cakes containing powdered whole egg, fresh egg, and liquid whole egg. All the analysed egg replacers significantly differed from the control cakes, including low-protein egg replacement R4. Despite R4 achieving the highest specific volume (1.63 ± 0.07 mL/g) and comparable texture values, none of the examined egg replacers compared favourably with the egg control cakes regarding appearance, physical and textural properties, and nutritional value.

Hybrid governance and welfare standards for broiler chickens raised for human consumption

AbstractThis article examines the welfare standards that govern the lives of chickens raised for meat in Australia and the United Kingdom. While ‘meat chickens’ are subject to a wide range of welfare interventions, we focus on the development and implications of the ‘private’ standards which are the most significant determinants of meat chicken welfare in these jurisdictions: the RSPCA Approved Farming Scheme in Australia and the Red Tractor Chicken Assurance Scheme in the United Kingdom. While the jurisdictions appear to have a similar regime that favours private regulation, differences in the origins and governance of these systems can be identified, offering insights into the use of hybrid regulation in areas associated with the welfare of non‐human animals. The similarities and differences in these countries point to the importance of individual relationships, as well as supply chain power in the adoption of private standards as a response to comparatively unstructured community concerns about welfare (Australia) and welfare and food safety (United Kingdom). While hybridity as a form of new public governance can be seen to facilitate innovative and varied responses to state devolution, the article concludes the overarching anthropocentrism of policymakers and the policy sciences explains a closed, incremental, and conservative form of practice in this area. Observations of the wider ‘animal turn’ in the social sciences are recommended to consider future systems of hybrid regulation that are not centred on anthropocentrism and more fully expand hybridity's participatory promise.Points for practitioners Hybrid governance can focus on the use of hybrid organisational design and/or hybrid regulatory practice; each has very different characteristics and their respective use is often a function of local conditions and situations. Hybrid standards‐making systems need to be open to public participation in development and implementation (oversight), or risk capture and moral hazard. Public policy is largely predicated on strong anthropocentrism, which can be addressed through the use of critical rather than simple pluralism to expand the number of interests captured in regulatory practices.

End of the Cage Age? A Study on the Impacts of the Transition from Cages on the EU Laying Hen Sector

This paper’s main objective is to assess the impacts of the ban on cages for housing laying hens, planned by the European Commission to raise animal welfare standards beyond the level set in the current legislation. The farm-level economic assessments of the ban were carried out in three stages: farm surveys and expert consultations, farm-level analyses, and aggregation to the EU-27 egg production sector. Four scenarios were constructed. All financial estimates were conducted with fixed prices from the year 2021 for which the reference scenario was built. Alternative hen-housing systems were barn (Voliera), free range, and organic. Until now, more than 50% of laying hens in the EU have already been transferred to alternative systems. The remaining part is subject to the transition. The basic assumptions included a reduction in yields due to the required lower densities and specifics of the production systems. A factor strongly differentiating the scenarios is likelihood of exists form the sector, as declared in the survey by many farmers, mainly those reaching retirement age without successors and keeping relatively small flocks of hens. The introduction of the ban will cause a decrease in egg production, varying between the scenarios. Substantial investments will be required within the range of 2–3.2 billion EUR, depending on the scenario.

Monitoring welfare indicators of rainbow trout (Oncorhynchus mykiss) in a commercial organic farm: Effects of an innovative diet and accelerometer tag implantation

To meet the growing demand for aquatic products, the aquaculture sector is expanding, including organic aquaculture. One of the main challenges in this industry is the development of suitable fish feeds. EU regulations have made recommendations, including the incorporation of fishmeal from organic aquaculture trimmings. However, the use of such fish meal may pose issues due to lower protein content and elevated phosphorus concentrations that could conflict with national environmental regulations. Thus, there is a pressing need for innovative research to formulate environmentally friendly feeds for organic aquaculture. This study aims to evaluate the feasibility of utilizing an innovative organic feed derived from trimmings (substitution of 64.3% of dietary fish meal trimmings with fishmeal protein concentrate from trimmings) for rainbow trout (Oncorhynchus mykiss). This study assessed the impact of this innovative diet on rainbow trout welfare over a two-month period in real-farming conditions, using: (i) growth parameters, (ii) external morphological damages, (iii) swimming activity, used as a proxy for energy expenditure, and (iv) blood and liver health and welfare indicators. Given that fish swimming activity was evaluated using surgically implanted accelerometer tags, we also investigated the potential adverse effects of implanting these tags on fish welfare. Our findings indicate that accelerometer implantation did not significantly affect fish welfare, but a 18.6% reduction in specific growth rate was shown in tagged fish compared to their non-tagged counterparts. Importantly, the innovative diet did not impair health and welfare indicators of blood and liver or lead to external morphological abnormalities. An increased energy expenditure in fish fed the innovative diet compared to those on a control diet was, however, shown, but there was no observable impact on growth performance. The use of this innovative diet may offer a viable solution to reduce the release of soluble phosphorus into the environment while maintaining appropriate standards for fish growth and welfare in organic conditions. Nevertheless, long-term consequences should be explored.

Animal welfare during transport, evolution, and perspectives of European Union Legislation and Policy.

In the one health approach, which summarizes the concept that human, animal, and plant health are interdependent and linked to the ecosystems in which they exist, animal welfare assumes an important role. In addition, the Farm to Fork Strategy of the European Union recognizes animal welfare as an essential component. Transport of animals involves a number of issues related to welfare. Animals are subjected to continuous stress, not only during transit on vehicles, vessels, trains, or airplanes, but also during loading and unloading operations. The handling and transport conditions have improved from basic and relatively rudimentary systems, with elements to attenuate the discomfort of animals having been gradually introduced, especially for long-distance transport. Despite several improvements in animal welfare standards during transportation there are still pressing issues in current EU legislation which deserve reviewing. Recently, several scientific opinions on animal welfare, including during transport, have been published by the European Food Safety Agency, following requests by the European Commission. In addition, the European Court of Auditors published its last report focused on animal welfare during transport. These reports underline the need to review current legislation governing the topic and highlight a number of outstanding issues in the European Union and in Third Countries. This article summarizes the history and current status of this complex issue.

Result of Human-induced Hybridization--Cat Born with Genetic Defect

Advancements in genetic science have facilitated the creation of popular cat breeds like the Scottish Fold and Munchkin, often admired for their distinct physical features and affable personalities. While these innovations mark a significant stride in the domain of genetic manipulation, they are not devoid of controversy, often giving rise to pressing ethical concerns. This arises primarily due to the potential health issues that such breeds might inadvertently inherit, coupled with diminished survival skills should they find themselves in the wild. Moreover, this pursuit of desired traits sometimes overshadows the imperative of ensuring robust animal welfare standards. As humanity delves deeper into the realms of genetic science, striking a harmonious balance between technological progression and safeguarding the intrinsic rights and well-being of these animals becomes increasingly pivotal. This underscores the compelling need for ethical responsibility in steering genetic advancements, fostering a future where technology serves as a boon rather than a bane in the evolutionary narrative of these beloved feline companions.
