实验动物的环境与福利

实验动物在生物科学研究领域中的应用不断发展,其饲养环境和福利保障的问题已越来越被国际所关注。实验动物的环境与福利不仅是对动物本身的保护,更重要的是对动物试验结果的保证。本文详细论述了大环境（温度、湿度、气流等方面）及小环境（笼具、饲养密度、垫料）对实验动物福利的影响,通过总结国内外的研究概况,旨为我国改善和提高实验动物的福利提出一些思路。     

实验动物福利与人的保护

实验动物学是一门研究实验动物和动物实验的综合性学科。是生命科学研究的基础和支撑条件。随着社会经济的长足发展和生命科学研究的突飞猛进,国际交流与合作的不断加强,实验动物福利倍受人们的关注。进入21世纪后国际上又对从事实验动物饲养管理和动物实验的工作人员的防护问题提出了新的要求,这就要我们必须考虑到人与实验动物如何和谐相处,促进科学发展。既要做到加强动物福利,又要注意人的保护,找到二者之间的平衡点,加快实验动物科学的发展。

Belief in Animal Mind among Spanish Primary School Children

Beliefs concerning the mental experiences of nonhuman animals have been related to how people treat, see, and take care of nonhuman animals. Whereas this issue has been the subject of several studies on adults, few have been conducted with children. Taking advantage of a recently published scale, the Child-BAM questionnaire, we aimed to explore the beliefs in animal minds of Spanish primary school children. The study also considered the effects of a child's age, school year group, gender, and pet ownership on their beliefs in animal mind. The Child-BAM questionnaire, concerning the mental capabilities of eight different species (human, chimpanzee, dog, cow, otter, sparrow, frog, and fish), was distributed at a primary school sited in Cordoba, Spain. A total of 416 participants were included aged between 6 and 13 years. Each child provided scores for animals’ ability to have intelligence, experience pain, fear, happiness, and sadness, and total scores for the eight species were calculated. The results showed that children's beliefs about animal minds differed depending on the type of animal, and that children were more likely to believe in the emotional capacities of animals rather than their cognitive capabilities. Dogs achieved similar scores to humans regarding all capabilities, and higher than any other species, while the cow, fish, and frog generally scored the lowest. Age, school year group, and having a companion animal at home affected beliefs in animal minds, whereas gender had no effect. This study highlights cultural similarities in children's beliefs about animal minds and the potential importance of this variable for future research in child–animal interactions.     

An Evaluation of a Pet Ownership Education Program for School Children

ABSTRACT

Children aged 5 to 6 years are disproportionately susceptible to dog bite attacks relative to the adult population and there is a need to provide them with well-validated education programs to teach correct behavior when interacting with dogs. The main aim of this study was to assess the immediate and longer-term learning outcomes of the Responsible Pet Ownership Program (RPOP), delivered to young Australian children in their preparatory year of primary schooling. A further aim was to investigate the impact of class size on learning outcomes of the RPOP. Children's ability to identify potentially dangerous dogs through canine body language, their knowledge of how to interact with dogs, and their knowledge of aspects of responsible pet ownership were assessed by measuring the immediate (within 2 weeks following the RPOP) and delayed (2 and 4 months post-RPOP) retention of this knowledge. Preparatory-aged children who had participated in the RPOP showed a better capacity to correctly identify emotions in cartoon, photographic, and video depictions of dogs than did those children who had not. In general, this effect did not persist 4 months after completion of the RPOP. In the case of the photographic presentations, children could correctly identify an angry dog, although this had disappeared in the groups that were assessed 2 and 4 months after the program. Children's role-play responses to interacting with a dog and its owner persisted for 4 months after the RPOP. In general, children did not identify dog behaviors that were relevant to the emotions of anger, fear, or happiness that had not been included in the RPOP. This suggests that there is specificity in the knowledge that the children received from the program. Children's knowledge of responsible pet ownership was higher for those who had just been through the program compared with those who had not. There was little evidence of retention of this information 2 and 4 months after instruction. Results suggest that the test measures used are appropriate to assess the effects of the program with young children. That little longer-term retention of information (especially 4 months post-RPOP) was evident indicates the need for follow-up instruction to improve the longer-term learning outcomes of the RPOP.     

The Role of Cognitive Styles and Sociodemographic Characteristics in Consumer Perceptions and Attitudes Toward Nonhuman Animal Welfare

Given the increasing importance of exploring consumers' concerns about the welfare of farmed animals, a survey questionnaire was designed to investigate the role of cognitive styles along with sociodemographic characteristics in consumers' perceptions about nonhuman animal welfare (AW) and their willingness to pay for animal-friendly products. The results revealed that the survey respondents were concerned about AW and had negative perceptions of the way animals were treated. They showed positive attitudes toward some actions to be taken for improving AW and strongly agreed to pay more for animal-friendly products. Consistent with previous studies, results revealed significant associations between sociodemographics and concern toward AW. However, some observed differences were highlighted by cognitive styles rather than by sociodemographic characteristics. These results indicate a significant link between cognitive styles and perceptions and attitudes toward AW, which may outweigh previously found sociodemographic differences and fuel the contemporary debate on AW.     

A Collaborative Model for Managing Animal Hoarding Cases

Companion-animal hoarding is a significant problem in the United States and internationally. Hoarding situations can incubate for years before a case is reported to law enforcement or animal control agencies. According to a survey by Gary Patronek, animal control agencies have estimated there are approximately 3000 reportable cases of animal hoarding annually in the United States. Animal hoarding cases vary in size from fewer than 20 animals to hundreds of animals. Every case of animal hoarding results in suboptimal animal welfare. Wake County, North Carolina, developed a proactive plan for addressing companion-animal hoarding that implemented a team approach to assist animals at risk, hold people accountable, address the mental health component of this problem, and create a more humane community. The plan involved animal control officers, crisis intervention counselors, law enforcement officers, veterinarians, veterinary technicians, and animal rescue partners. This intervention strategy was implemented in 2015, and cases were tracked to document animal outcomes. The conclusion of this experience is that a diverse team approach can best address the animal and human welfare challenges and the environmental concerns associated with animal hoarding.     

Application of the Hands-On Donkey Tool for Assessing the Welfare of Working Equids at Tuliman,Mexico

Equids are still used for diverse chores in Mexico and are essential for the livelihoods of numerous families. Appropriate health and behavior are prerequisites for performing work without affecting welfare. This study aimed to assess the welfare of working equids in Tuliman, applying the hands-on donkey tool. This tool evaluates five dimensions (behavior, body condition score [BCS], wounds, lameness, and other health issues) and was applied to 438 working equids (horses, mules, and donkeys). The Kruskall-Wallis test was applied to investigate differences between species and sex. Donkeys were more common; they also presented more positive behaviors and less lameness (p < 0.05). No differences were found for BCS among species on a scale ranging from 1 to 5 (mean BCS for donkeys = 1.9; mules = 2; and horses = 1.8). Mares had significantly lower BCS (mean = 1.5) than stallions (p < 0.05) and geldings (mean = 1.9). Overall mules had better welfare evaluations. The tool allowed detection of welfare issues in working equids; a practical outcome would be implementing local welfare strategies according to its results.     

Perceptions of Social Responsibility of Prominent Animal Welfare Groups

Nonhuman animal welfare is an increasingly important component of consumer expectations of corporate social responsibility (CSR). The extent to which prominent animal welfare or protection organizations may influence people’s perceptions of food industry CSR may be related to an organization’s perceived social responsibility. Data from an online survey of 300 U.S. residents were used to explore relationships between demographics/lifestyle choices and perceptions of prominent animal welfare organizations (using best–worst scaling methodology). Overall, the American Society for the Prevention of Cruelty to Animals was perceived to be the most socially responsible organization analyzed, followed by the Humane Society of the United States and the American Humane Association (AHA). Results suggest that the perceived social responsibility of animal protection organizations in this study was not strongly linked to personally (financially) supporting them, with 2 exceptions: the perceptions of People for the Ethical Treatment of Animals and AHA. Improved understanding of the perception of animal welfare or protection organizations can inform decision making by organizations interested in furthering animal welfare causes.     

宠物的福利和管理

＂家庭动物＂或＂伴侣动物＂的提法较＂宠物＂而言,更为确切并规范。伴侣动物往往因为种种原因成为城镇的流浪动物,在一定程度上,已经成为社会问题。遗弃宠物的原因尽管多种多样,深层次原因主要还是伦理道德的缺失。流浪动物日益泛滥,正在拷问人类的精神文明,有必要引起全社会的关注。动物福利在当今社会已不仅仅是概念化的一般性号召,一些发达国家出版的动物法典对犬、猫的福利有专题阐述。法典不仅对伴侣动物的各种福利条件作了具体规定,同时还提出了最低标准和最佳方案。本文以犬的食物饲喂、饮水及犬舍的要求为例,逐一介绍。     

Animal Welfare Knowledge,Attitudes, and Practices of Stockpersons in Kenya

The stockpersons handling the transportation of animals between farms and slaughterhouses are rarely assessed for their animal welfare knowledge, attitudes, and practices (KAP). Thus, this investigation presents a unique opportunity to study these interactions. Herein, a cross-sectional survey was carried out among 266 stockpersons in 10 Kenyan livestock markets to determine their animal welfare KAP. The survey questionnaire was based on Kenya’s Regulations for Animal Transport (Act No: CAP. 360-L.N. 119/1984). Mean percentage scores for knowledge, attitudes, and practices were 78.0 ± 14.1, 75.6 ± 16.0, and 64.5 ± 17.6, respectively. From the responses to statements related to animal husbandry, practices of the housing of unfamiliar groups of animals, cooperation with other stakeholders, and stress caused to animals during handling, it was found that stockpersons’ animal welfare KAP was inadequate. Women aged > 50 years or having more than 10 years of experience had significantly higher levels of animal welfare KAP (p < 0.05). In conclusion, although Kenyan stockpersons may score adequately on the parameters of animal welfare knowledge and attitudes, their followed practices are poor, which may possibly be influenced by gender, age, or level of experience.     

Cost-Effectiveness Analysis of Chemical Testing for Decision-Support: How to Include Animal Welfare?

Toxicity testing for regulatory purposes raises the question of test selection for a particular endpoint. Given the public's concern for animal welfare, test selection is a multi-objective decision problem that requires balancing information outcome, animal welfare loss, and monetary testing costs. This paper demonstrates the applicability of cost-effectiveness analysis as a decision-support tool for test selection in a regulatory context such as, for example, the new European chemicals legislation (REACH). We distinguish different decision-making perspectives, in particular the regulator's and chemical industry's perspectives, and we discuss how cost-effectiveness analysis can be applied to test selection from both perspectives. Furthermore, we show how animal welfare goals can be included in cost-effectiveness analyses, and we provide a three-dimensional extension to the standard cost-effectiveness analysis if animal welfare loss cannot be valued in monetary terms. To illustrate how cost-effectiveness analysis works in different settings, we apply our model to a simple case of selecting short-term tests for mutagenicity. We demonstrate that including sufficiently high values for animal welfare induces cost-effective replacements of animal testing. Furthermore, we show that the regulator and chemical companies face different tradeoffs when selecting tests. This may lead to different choices of tests or testing systems.     

Cross-Sectional Study of Characteristics of Owners and Nonowners Surrendering Cats to Four Australian Animal Shelters

Unwanted cats surrendered to nonhuman animal shelters are generally categorized as either “owned” or “stray.” This classification is misleading because “stray” cats may include many “semiowned” cats, for which people provide care but who are not perceived as being owned. This differentiation is important because effective strategies designed to reduce cat admissions to, and euthanasia rates in, shelters rely on accurate information about cat populations contributing to shelter intake; cat semiowners will likely respond to different strategies than people with no relationship with the cats they surrender. People surrendering cats to four Australian animal shelters were surveyed to identify factors associated with perception of ownership. Many self-classified nonowners had fed the cats they surrendered, often for a considerable period of time. The factor most strongly associated with ownership perception was an increasing association time with the cat. These findings confirm that enduring relationships between surrenderers and cats, consistent with cat semiownership, are common for cats surrendered to Australian animal shelters. This finding should be taken into account when planning education messages and cat population management strategies aimed at reducing cat admissions.     

Behaviour as a tool in the assessment of animal welfare

A central issue in animal welfare research is how to assess the welfare state of animals objectively and scientifically. I argue that this issue can be approached by asking two key questions: 1) is the animal physically healthy and 2) does the animal have what it wants? Behaviour is used to answer both of these questions. In the assessment of physical health, it can be used for clinical and pre-clinical diagnosis. In the assessment of what animals want, it has a major role through choice and preference testing. It is particularly important that applied ethologists develop methods for assessing welfare in situ--in the places where concern for animal welfare is greatest such as on farms and in zoos.     

Development of a Canine Care and Welfare Knowledge Scale: Implications for Welfare and Preventing Dogfighting

The objective of this study was to develop a Canine Care and Welfare Knowledge (CCWK) Scale for use in educational intervention development and evaluation and validate the instrument. The study population was 504 children, aged 11 to 19 years old, from Detroit, MI. In this cross-sectional study, exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used for scale development. The EFA and CFA of the CCWK Scale revealed a 2nd-order model with 6 factors to be a good fit of the data (chi-square [df = 269] = 433, p < .05, Comparative Fit Index = .94, Tucker-Lewis Index = .93, root mean square error of approximation = .05) with a Cronbach’s alpha of .78. The scale is valid and reliable to assess the study population’s CCWK.     

影响动物模型MBLUP评定准确性的主要因素

标记辅助最佳线性无偏预测（marker-assisted best linear unbiased prediction,MBLUP）是对动物实施标记辅助选择（marker-assisted selection,MAS）的一种重要方法。通过计算机随机模拟研究了所选性状的遗传力、QTL方差和相邻两个标记间图距3个因素对动物模型MBLUP评定准确性的影响。结果表明,性状的遗传力越高、QTL方差和相邻两个标记间图距越小时,动物模型MBLUP评定的准确性越高;相反,当性状的遗传力较低、QTL方差和相邻两个标记间图距较大时,动物模型MBLUP评定的准确性则较低。     

Assessing the Effectiveness of a Training Program for Interviewing Child Witnesses

Twenty-seven experienced interviewers attended a 10-day training institute designed to provide knowledge and skills for improving investigative interviews with young children. Participants completed pre- and posttraining surveys assessing their knowledge of the scientific evidence regarding memory, suggestibility, and other aspects of children's ability to provide accurate accounts of events during interviews. They also conducted pre- and posttraining interviews with preschool children about 2 previously experienced events. Participants' knowledge about children's abilities and the scientific basis of various interviewing protocols increased significantly after the training. However, training did not have a significant impact on interviewers' questioning styles or the amount of accurate information elicited from the children. Results indicate that successfully translating knowledge into practice requires multiple opportunities for skill practice and feedback.     

The status and issues of the Institutional Animal Care and Use Committee of Seoul National University: from its establishment to the present day

The Institutional Animal Care and Use Committee (IACUC) of Seoul National University (SNU) plays a key role in monitoring and managing the humane use of animals in scientific research. Here, as one of the pioneers of the IACUC in Korea, we reported SNU-IACUC operations and activities including committee establishment and legal formulation, protocol review, and post-approval monitoring of protocols, which the IACUC has undertaken in the last decade. In addition, legal regulations and improvements were also discussed, and encompassed the limited number of committee members and the single IACUC policy in Korea. As of December, 2020, amendments are on the table at the National Assembly. We also emphasized the independent nature of the IACUC in protecting activities, including approval and monitoring animal experiments, and its public role in narrowing the knowledge gap between society and scientists. Thus, the aim of this report is to help society and scientists understand the operations of the SNU-IACUC and its role in animal welfare.
