CE DAYTIME SESSIONS
REFINEMENTS IN ANIMAL WELFARE FROM LARGE TO SMALL Kristina Bartley, B.Sc. M.Sc. CLABP 3:00 PM - 3:50 PM | Room 110 B This lecture presents a comprehensive overview of the advancements and refinements in animal welfare practices, spanning from large to small animals. It aims to elucidate the evolutionary journey of animal welfare science and its practical applications, emphasizing the integration of ethical considerations into the care and management of diverse animal species. Beginning with a historical perspective, the lecture will trace the development of animal welfare as a scientific discipline, highlighting key legislative milestones and the influence of societal attitudes towards animals. It will then delve into the specific welfare needs and considerations for large animals such as horses, cattle, and pigs, addressing topics such as housing, nutrition, social needs, and humane handling practices. The discussion will transition to the unique challenges and strategies associated with the welfare of smaller animals, including laboratory rodents, rabbits, and companion animals like dogs and cats. This section will explore the refinement of housing and husbandry practices, environmental enrichment, and the importance of addressing psychological well-being alongside physical health. Interactive case studies and examples of best practices will be integrated throughout the lecture to illustrate the practical application of welfare principles and the positive impact of refinements on animal well-being and scientific outcomes. The session aims to foster a deep understanding of the multifaceted nature of animal welfare, encouraging a proactive approach to welfare enhancement across all sectors involving animals. Targeted at students, researchers, veterinarians, and animal care professionals, this lecture seeks to inspire a commitment to continual improvement in animal welfare practices. UNEXPECTED DEATH OF VETERINARY PATIENTS: A PRACTICAL GUIDE TO COMPLETE NECROPSY FOR THE CLINICAL VETERINARIAN Olga Gonzalez, DVM, Diplomate ACVP 4:30 PM - 5:20 PM | Room 110 B Necropsy procedures can be completed efficiently and timely if a systematic approach is established. This approach will ensure that all organ systems are evaluated grossly and samples collected for histopathology. Obtaining digital photos is helpful for documentation and sharing with the veterinary
transmission modes in humans include transplacental/congenital, ingesting contaminated food, blood transfusion, and organ transplants. T. cruzi can cause lethal acute disease, chronic or reactivating disease in humans, domestic and wildlife species. Like other vertebrate hosts, outdoor-housed chimpanzees, baboons, and rhesus macaques are susceptible to T. cruzi transmission via kissing bug feces, leading to Chagas disease. Myocarditis with intralesional T. cruzi trophozoites resulting in heart failure is the most frequent pathology observed in adult non-human primates. Associated pathologies of heart failure include cardiomegaly, hydropericardium, hydrothorax, ascites, skin edema (facial and scrotal), and systemic manifestations include orchitis, ganglioneuritis, and myositis of the digestive system's muscular layers. Managing an outdoor housed facility remains challenging, requiring aggressive control measures and frequent serological screening. COMPARATIVE PATHOLOGY OF TUBERCULOSIS IN RESEARCH MODELS, DOMESTIC AND WILDLIFE SPECIES Olga Gonzalez, DVM, Diplomate ACVP 2:00 PM - 2:50 PM | Room 110 B Texas Biomedical Research Institute (TxBiomed) has two biosafety level 3 (BSL-3) laboratories focused on developing animal models for Mycobacterium tuberculosis (Mtb). Researchers at TxBiomed study how Mtb replicates and spreads in vivo using rodent and non-human primate models. TxBiomed veterinary pathologists support the high containment program by performing necropsies and generating data detailing the pathology. Necropsy procedures follow established protocols with whole body assessment, and tissue collection lists similar to necropsies performed in a diagnostic setting. Necropsies are performed inside the BSL-3 laboratory with additional safety measures, including specialized personal protective equipment. Rhesus macaques are experimentally infected with Mtb via aerosol or intra-tracheal inoculation. Systemic pathologic markers of Mtb infection of rhesus macaque models are similar to humans, domestic, and wildlife species. These include the following observable features: granulomatous pneumonia with local and systemic dissemination to other vital organs and disease progression. Necropsy findings are critical for validating the qualities of an NHP research model and assessing the effectiveness of interventional strategies.

pathologist if samples are referred to a diagnostic laboratory. Often, toxic causes of animal death have subtle gross lesions; therefore, establishing essential organ and fluid collection for broad toxicologic screening may help pinpoint the cause of death. Risk assessment of zoonotic potential should also be considered. The quality of the sample submitted to the referral laboratory will directly impact the quality of the diagnostic evaluation. Packaging and shipping samples are equally crucial, as formalin fumes may affect cytological specimens, bacterial isolation, and downstream molecular diagnostics. The lecture will demonstrate cases where the systemic necropsy approach helped elucidate the cause of unexpected animal death in the veterinary setting. SATURDAY, SEPTEMBER 28 _______________________________________ NONHUMAN PRIMATE SOCIAL HOUSING SCENARIOS Kristina Bartley, B.Sc. M.Sc. CLABP 9:00 AM - 9:50 AM | Room 110 B Nonhuman primates (NHPs) have been invaluable in advancing our understanding of various aspects of biomedical research, from drug development to infectious disease studies. Social housing of NHPs is a critical aspect of their well-being, as it can significantly impact the validity of experimental outcomes, the animals' psychological health, and ethical considerations. This lecture explores the diverse social housing scenarios for NHPs in biomedical research settings, emphasizing the importance of choosing appropriate housing configurations that align with scientific goals while ensuring the animals' welfare. The lecture will discuss various factors influencing social housing choices, such as species-specific requirements, age, sex, and experimental objectives. It will delve into the advantages and challenges associated with pair, group, and multi-tiered housing systems, as well as the effects of social hierarchy on research outcomes and animal well-being. Additionally, it will address the importance of environmental enrichment and social complexity in promoting NHP psychological health. Ultimately, this lecture aims to provide researchers, animal care professionals, and stakeholders in biomedical research with valuable insights into optimizing nonhuman primate social housing scenarios, fostering scientific rigor, animal welfare, and ethical standards within the field. DEVELOPING ENRICHMENT THAT WORKS: TIPS ON HOW TO CREATE, IMPLEMENT AND EVALUATE NEW AND EXISTING ENRICHMENT/ BEHAVIOR MANAGEMENT PRACTICES IN YOUR FACILITY Kristina Bartley, B.Sc. M.Sc. CLABP 10:30 AM - 11:20 AM | Room 110 B Enrichment plays a pivotal role in enhancing the physical and psychological well-being of animals in captive environments. This lecture provides a comprehensive guide for professionals involved in animal care and management, offering valuable insights into the development, implementation, and evaluation of effective enrichment strategies. The lecture will begin by emphasizing the importance of enrichment in maintaining optimal animal health and behavior. It will then delve into practical tips and strategies for creating innovative and species-specific enrichment programs tailored to the unique needs of animals in your facility. Attendees will gain a deeper understanding of how to incorporate elements of novelty, complexity, and choice into enrichment design, ensuring maximum engagement and satisfaction for the animals. Implementation challenges, budget constraints, and regulatory considerations will also be addressed, helping attendees navigate the practical aspects of enrichment program execution. Furthermore, the lecture will explore ways to involve staff, volunteers, and stakeholders in the enrichment process, fostering a culture of continuous improvement within the facility.
