Selection, acclimation, training, and preparation of dogs for the research setting

Dogs have made and will continue to make valuable contributions as animal models in biomedical research. A comprehensive approach from time of breeding through completion of in-life usage is necessary to ensure that high-quality dog models are used in studies. This approach ensures good care and minimizes the impact of interanimal variability on experimental results. Guidance related to choosing and developing high-quality laboratory dogs and managing canine research colonies is provided in this article. Ensuring that dogs are healthy, well adapted, and cooperative involves good communication between vendors, veterinarians, care staff, and researchers to develop appropriate dog husbandry programs. These programs are designed to minimize animal stress and distress from the postweaning period through the transfer and acclimation period within the research facility. Canine socialization and training programs provided by skilled personnel, together with comprehensive veterinary health programs, can further enhance animal welfare and minimize interanimal and group variability in studies.     

Reduction through education: the insight of a trainer

One of the articles contained within European Council Directive 86/609/EEC states that "Persons who carry out experiments or take part in them, and persons who take care of animals used for experiments, including duties of a supervisory nature, shall have appropriate training". In effect, this article stipulates that only competent individuals are allowed to work with laboratory animals. At least three groups of individuals can be identified with different responsibilities toward experimental animals: animal technicians, scientists, and veterinarians/animal welfare officers. The responsibilities and duties of the individuals within each of these categories differ. This paper focuses on the training of scientists. The scientist designs, and often also performs, animal experiments. Therefore, scientists must be educated to develop an attitude of respect toward laboratory animals, and must be trained so that, if an experiment must be performed with animals, it is designed according to the highest possible scientific and ethical standards. In The Netherlands, the law stipulates that scientists intending to work with animals must have completed a course in laboratory animal science. This compulsory course started in 1986. The Department of Laboratory Animal Science at Utrecht University is responsible for the national coordination of this course. Participants must have an academic degree (at the level of MSc) in one of the biomedical sciences, such as biology, medicine or veterinary medicine. Although the course is an intensive 3-week, 120-hour long course, which covers both technical and ethical aspects of laboratory animal experimentation, it cannot provide full competence. It is designed to provide sufficient basic training and knowledge to enable students to design animal experiments, and to develop an attitude that will be conducive to the implementation of the Three Rs. However, full competence will always require further training that can only be acquired as a result of practical experience gained while working in the field of laboratory animal research. Evaluations subsequent to the course have revealed that more than 98% of the students regard the course as indispensable for all scientists working in a research area where animal experiments are performed. They agree that the course not only contributes to the quality of experiments and to the welfare of animals, but also to a decrease in the number of animals used in experiments.     

Designing Graduate Training Programs in Conservation Medicine—Producing the Right Professionals with the Right Tools

New challenges to human, animal, and ecosystem health demand novel solutions: New diseases are emerging from new configurations of humans, their domestic animals and wildlife; new pressures on once robust and resilient ecosystems are compromising their integrity; synthetic compounds and engineered organisms, new to the natural world, are spreading unpredictably around the globe. Globalization provides opportunities for infectious organisms to gain access to new hosts, changing in distribution and virulence. What type of training should be developed to provide professionals with the right tools to meet these challenges? In this article, we offer recommendations for developing academic programs in conservation medicine. We discuss the need for, and the advantages to, using a conservation medicine approach to address real world situations and present illustrations of how this is applied today. We suggest a core set of skills that are needed in a conservation medicine practitioner, and recommend key considerations for designing new conservation medicine training programs. We review existing programs that offer conservation medicine content, and provide examples of where opportunities exist for those interested in pursuing a conservation medicine career.     

Guidelines for the veterinary care of laboratory animals: report of the FELASA/ECLAM/ESLAV Joint Working Group on Veterinary Care

Veterinary professionals working in partnership with other competent persons are essential for a successful animal care and use programme. A veterinarian's primary responsibilities are defined by their own professional regulatory bodies, but in this area of work there are further opportunities for contribution, which will assist in safeguarding the health and welfare of animals used in research. These guidelines are aimed not only at veterinarians to explain their duties, and outline the opportunities to improve the health and welfare of animals under their care, but also at employers and regulators to help them meet their responsibilities. They describe the desirability for postgraduate education towards specialization in laboratory animal medicine and detail the many competencies necessary to fulfil the role of the laboratory animal veterinarian. They detail the need for veterinary expertise to promote good health and good welfare of animals used in biomedical research during husbandry as well as when under experimental procedures. Regulatory and ethical aspects are covered as are the involvement of the veterinarian in education and training of others working in the animal care and use programme. Managerial aspects, including occupational health and safety, are also areas where the veterinarian's input can assist in the successful implementation of the programme.     

Enrichment and nonhuman primates: "first, do no harm"

Since the 1998 publication of The Psychological Well-Being of Nonhuman Primates by the National Research Council, and the 1991 implementation of the 1985 Animal Welfare Act Amendment, many formal and informal nonhuman primate enrichment programs have been put into practice. Reports of their successes and failures, however, are few. All programs have at least two things in common: (1) They are best when designed and maintained by teams of individuals with species-specific expertise; (2) the members of those teams, the stakeholders, usually include principal investigators, animal care and use committee members, veterinarians, and animal care staff. Discussions in this article address general principles about enrichment, goals of such programs from the perspective of each of the major stakeholders, and recently published sources of related information. These discussions follow the central premise that enrichment should benefit all involved and "First, do no harm."     

50 years of the Institute for Laboratory Animal Research (ILAR): 1953-2003

The history of the Institute for Laboratory Animal Research (ILAR) begins, as does all of laboratory animal science, with the ancient philosophers, anatomists, and physiologists whose work presaged the use of animals in biomedical research and the institutions that arose due to this use. Modern laboratory animal science and medicine began in the late 1940s and early 1950s as five Chicago-area institutions hired veterinarians to manage their animal facilities. Each of these men became instrumental in the founding of the organizations that collectively make up the laboratory animal science and medicine organizations. Nathan Brewer, one of the "Chicago five," was particularly influential in the founding of ILAR. His boss at the University of Chicago, Dr. Paul Weiss, a member of the National Academy of Sciences (NAS), asked him to help establish a committee with the stated purpose of preparing recommendations to the NAS to develop an office to obtain information on sources of supply for research animals. This office became ILAR, and Brewer was chairman of its first report on the diseases of laboratory animals. He was also a founding diplomat and first president of the American College of Laboratory Animal Medicine. This history recognizes the thoughtful and energetic contributions of scientists and veterinarians to ILAR. It provides a 50-year overview of the programs and reports of ILAR and highlights examples where these reports have been adopted by scientists and federal agencies and incorporated into national laws and policies governing the use of animals in research both in the United States and in other countries.     

A primer in epidemiologic methodology

Epidemiology is defined as the study of the distribution and determinants of disease within populations. In addition to the requirements for disease surveillance, epidemiologic methods have numerous applications in laboratory animal science and can reveal important insights into the multifactoral mechanisms of disease, thereby aiding in the design of optimized intervention strategies. Observational approaches to data collection can be used to quantify the role of causal factors under natural circumstances, complementing the value of experimental studies in this field. The meaning and appropriate use of standard measures of disease frequency and exposure-disease relationships are reviewed, along with explanations of bias and confounding. Recommendations for reporting the methods and findings from this type of work in comparative medicine literature are presented. Aspects of model-based approaches to data analysis are introduced, offering further opportunities for gaining needed information from epidemiologic study of problems in laboratory animal medicine and management.     

ACADEMIC VS. INDUSTRIAL PERSPECTIVES ON SENSORY EVALUATION

The current practice of sensory evaluation occurs in two general settings: the academic environment of a university laboratory and within the foods and consumer products industries. Sensory evaluation programs can differ in orientation, objectives, methodology and context, and viewed from the perspective of Brinberg's tripartite validity theory, focusing on experimental, theoretical and empirical paths. Differences in organizational goals and resources between academia and industry result in different uses of panels, statistics and collaborative efforts. Opportunities for advancement of the field of sensory science exist within the framework of academic training of and industrial demand for sensory professionals.     

Veterinary medicine in the 21st century: the challenge of biosecurity

The veterinary profession is presently challenged with developing and maintaining on-farm biosecurity protocols to protect the nation's food supply from acts of bioterrorism, from the growing threat of foreign animal diseases, and from multidrug resistance among pathogenic organisms. This challenge comes at a time when the supply of food animal veterinarians in the United States is progressively in decline, and raises the possibility that the profession is not adequately prepared to fulfill its responsibilities to the health and productivity of the US livestock and poultry populations. Causes of the decline in demand for veterinary services are discussed. They include consolidation of the food animal industries and a trend toward transferring performance of tasks traditionally carried out by veterinarians to the province of lay staff. This development potentially reduces veterinary surveillance of food animal populations. It also runs the risk of delay in recognizing and controlling serious health problems when they arise. Several remedies are proposed, including profound changes in the curriculum for educating food animal veterinarians to serve the consolidated but vulnerable livestock and poultry industries suitably. Also advocated is the initiation of training programs for herdsmen on the symptoms of foreign animal diseases, together with advice on when to call a veterinarian. Significant investment of federal or state resources will be required if these changes are to become reality.     

Training strategies for research investigators and technicians

Training programs for research personnel are discussed as a key resource that must be part of an effective animal care and use program. Because of the legal responsibility to ensure that research staff are qualified to use animals, many institutions have justified the necessity for a training coordinator and/or trainers for their animal care and use programs. Effective training programs for research personnel must meet the needs of the client base (research scientists and staff) so that they are relevant, practical, and timely. To meet these objectives, it is useful to involve the scientific staff in the analysis of their learning needs. To meet a performance standard necessary for quality research, a large percentage of the institutional staff must participate in the training program. Often it is the principal investigators who set the tone for their staff members regarding the importance of receiving training. Garnering support from this client base will create a culture that encourages training and engenders a positive attitude about humane animal care and use. One effective approach is to incorporate nonanimal models as alternatives to live animals to teach humane handling techniques and methods, thereby contributing to refinement, reduction, and replacement (the 3Rs). Also discussed are the necessity of timely feedback from clients, documentation of personnel training for regulatory purposes, and the collection of training metrics, which assists in providing justification for the granting of additional fiscal support for the program. Finally, the compliance procedures and opportunities for essential refresher training are discussed and related to high performance standards, humane animal use, and quality research, all of which contribute to the 3Rs.     

Assessing Youth Perceptions and Knowledge of Ethics at 4-H Horse Shows in Louisiana

Due to the increased awareness of animal welfare issues and sensitized attitudes throughout society, youth animal projects provide a unique opportunity to assess and impact youth understanding and attitudes regarding animal welfare. Animal ethics training is not an uncommon requirement for participants in 4-H livestock programs. However, participants in 4-H horse projects are not universally held to the same standard. The purpose of this study was to assess youth knowledge, attitudes, and confidence in understanding of equine welfare at the 4-H state horse show, as well as to determine the beliefs and observations of unethical practices, and if differences exist between those parameters in youth competitors. The results suggest that 4-H competitors are interested in ethics and believe that unethical behavior rarely occurs within the state 4-H horse project. However, youth report observing common unethical behaviors at the show, suggesting a disconnect between what they believe is unethical and what they actually observe. Educational opportunities exist within these animal projects and should be enhanced to address the gap in understanding.     

A Focused Ethnographic Study of Sri Lankan Government Field Veterinarians’ Decision Making about Diagnostic Laboratory Submissions and Perceptions of Surveillance

The global public health community is facing the challenge of emerging infectious diseases. Historically, the majority of these diseases have arisen from animal populations at lower latitudes where many nations experience marked resource constraints. In order to minimize the impact of future events, surveillance of animal populations will need to enable prompt event detection and response. Many surveillance systems targeting animals rely on veterinarians to submit cases to a diagnostic laboratory or input clinical case data. Therefore understanding veterinarians’ decision-making process that guides laboratory case submission and their perceptions of infectious disease surveillance is foundational to interpreting disease patterns reported by laboratories and engaging veterinarians in surveillance initiatives. A focused ethnographic study was conducted with twelve field veterinary surgeons that participated in a mobile phone-based surveillance pilot project in Sri Lanka. Each participant agreed to an individual in-depth interview that was recorded and later transcribed to enable thematic analysis of the interview content. Results found that field veterinarians in Sri Lanka infrequently submit cases to laboratories – so infrequently that common case selection principles could not be described. Field veterinarians in Sri Lanka have a diagnostic process that operates independently of laboratories. Participants indicated a willingness to take part in surveillance initiatives, though they highlighted a need for incentives that satisfy a range of motivations that vary among field veterinarians. This study has implications for the future of animal health surveillance, including interpretation of disease patterns reported, system design and implementation, and engagement of data providers.     

Conservation medicine and One Health in zoos: Scope,obstacles, and unrecognized potential

Zoo veterinarians and allied professionals have been contributing to conservation medicine (CM) and One Health (OH) activities for more than two decades. Although the Association of Zoos and Aquariums (AZA) considers conservation a key part of its mission, little published material exists about the extent of AZA work in CM/OH or the challenges and opportunities associated with these endeavors. To better understand the current scope of CM/OH in zoos, we surveyed 53 AZA‐accredited institutions from April through October of 2016. We obtained information on CM/OH infrastructure, support for expansion in this area, and strategies to overcome perceived obstacles hindering CM/OH from becoming a core AZA activity. Survey results revealed that while most zoos favor greater investment in CM/OH programs, awareness, and understanding of CM/OH across the broader zoo community and public is lacking. The majority of respondents stated that overcoming this challenge is paramount to attaining support for CM/OH initiatives. In spite of these obstacles, survey respondents highlighted many positive developments in CM/OH. We found that 84% of zoos surveyed are actively engaged in CM/OH activities, and 12% house formal CM/OH programs. Another 8% of respondents said their institutions were developing CM/OH programs. Perhaps most noteworthy, we found that zoo size did not have a significant bearing on the financial amount allocated toward an institution's CM/OH activities. This suggests that all zoos, regardless of size, can make meaningful contributions to the growing movement of CM/OH and help redefine the role of zoos within this movement.

Attitudes toward Animals of Students at Three European Veterinary Medicine Schools in Italy and Spain

The European Veterinary Code of Conduct recognizes the crucial role of veterinarians in improving animal welfare and maintaining its standards. However, several studies have claimed that veterinary students’ attitudes toward animals may worsen as they progress through their academic training. This study aimed to investigate students’ attitudes toward nonhuman animal use in three European veterinary medicine schools (Italy and Spain). For this purpose, 565 veterinary students completed a questionnaire consisting of a range of items grouped into four animal-use categories: “Research,” “Entertainment,” “Utilitarianism,” and “Veterinary Issues.” Items were scored on a 5-point Likert-type scale, with higher scores indicative of higher concern regarding animal welfare. Results showed that the use of animals for “Entertainment” and questions related to “Veterinary Issues” raised the most concern among the veterinary students, while the use of animals for “Research” was of least concern. Moreover, we also examined some potentially confounding factors: age, academic year (first to fifth), gender, previous experience with pets, and university. Female students had a higher concern for animal welfare compared with their male counterparts. Students in their earlier stages of training as veterinarians also exhibited a greater concern for animal welfare compared with those of later academic years. Other factors affecting students’ attitudes toward animal use were the age of the students and the university they were enrolled at. The findings of this study confirm that attitudes toward animal use are not homogeneous and are associated with students’ demographic, educational, and personal characteristics.     

Two pathways — Same destination: Development of educational programs in fish health

Educational programs in fish health have developed in several different settings during the 20th century. Two prominent programs which have played major roles in providing educational opportunities developed independently during the last 40 years yet display numerous similarities in their goals and approaches. One arose primarily from a freshwater fisheries biology perspective while the other found its roots in traditional veterinary medical education. Not surprisingly, their pathways converged in due time. The following articles provide a brief view of the origins, philosophies, and accomplishments of these two particular programs. Other programs exist and still others are needed to fully serve those seeking to become a part of the aquatic animal health field.
