Chemical safety in animal care,use, and research

Chemical safety is an essential element of an effective occupational health and safety program. Controlling exposures to chemical agents requires a careful process of hazard recognition, risk assessment, development of control measures, communication of the risks and control measures, and training to ensure that the indicated controls will be utilized. Managing chemical safety in animal care and use presents a unique challenge, in part because research is frequently conducted in two very different environments--the research laboratory and the animal care facility. The chemical agents specific to each of these environments are typically well understood by the employees working there; however, the extent of understanding may not be adequate when these individuals, or chemicals, cross over into the other environment. In addition, many chemicals utilized in animal research are not typically used in the research laboratory, and therefore the level of employee knowledge and proficiency may be less compared with more routinely used materials. Finally, the research protocol may involve the exposure of laboratory animals to either toxic chemicals or chemicals with unknown hazards. Such animal protocols require careful review to minimize the potential for unanticipated exposures of the research staff or animal care personnel. Numerous guidelines and regulations are cited, which define the standard of practice for the safe use of chemicals. Key chemical safety issues relevant to personnel involved in the care and use of research animals are discussed.     

Fish research and the institutional animal care and use committee

Fish represent the most diverse group of animals in the vertebrate phylum. The more than 25,000 species are characterized by an array of anatomical, biochemical, physiological, and behavioral repertoires. For this reason, it is difficult to develop a comprehensive guideline on the care and use of fishes. Institutional animal care and use committees (IACUCs) meet the challenge of ensuring adequate fish welfare using guidelines (Animal Welfare Act [AWA] and Public Health Service [PHS] Policy and their guides) derived mainly from the care and use of mammalian species, which may not be optimal for regulating fish research, teaching, or extension activities. Discussion focuses on various issues that often confront IACUCs in meeting regulatory requirements while assuring proper fish welfare. Issues include questions concerning animal tracking and inventory, utilization of fisheries bycatch, facility inspections in remote locations, and euthanasia. Common sense solutions appropriate for field and laboratory fish activities are suggested, which should help investigators, IACUCs, and regulatory agencies meet PHS and AWA objectives.     

Using obese mouse models in research: special considerations for IACUC members, animal care technicians, and researchers

The mouse is the animal most commonly used to study the underlying causes of and treatments for obesity. The author reviews many of the issues that should be considered by all involved in research with mice expressing this phenotype, and describes some procedures exclusive to obesity research.     

动物个性研究进展

"个性"是指不同时空条件下动物种群个体间行为的稳定差异。大量的理论和实验性研究表明,个性差异在动物界普遍存在,其是种群多度和分布、物种共存及群落构建的重要驱动因子。介绍了动物个性的概念、分类及衡量指标,将前人测量个性类型的方法加以总结;随后介绍了动物个性的生态学意义,尤其是个性对动物生活史策略、种群分布与多度、群落结构和动态、生态系统功能和过程以及疾病与信息传播等的影响。在此基础上,进一步分析了在人类活动增加等全球变化背景下,动物个性如何调控动物个体行为、种群和群落动态对这些环境变化的响应。阐述了动物个性的形成与维持机制,并对未来的研究方向进行了展望。     

Agricultural (nonbiomedical) animal research outside the laboratory: a review of guidelines for institutional animal care and use committees

Challenges and published guidelines associated with appropriate care and use of farm animals in agricultural research conducted outside the laboratory are briefly reviewed. The Animal Welfare Act (Title 9 of the 2000 Code of Federal Regulations), which regulates the care and use of agricultural animals in biomedical research, does not include livestock and poultry used in agricultural research. Farm animal research funded (and thereby regulated) by the US Public Health Service is further discussed in the National Research Council's 1996 Guide for the Care and Use of Laboratory Animals. However, neither of these guidelines adequately addresses the unique attributes of research and teaching designed to improve production agriculture. That information is contained in the Guide for the Care and Use of Agricultural Animals in Agricultural Research and Teaching (the Ag Guide), published by the Federation of Animal Science Societies in 1999. The Ag Guide provides excellent general recommendations for agricultural animal research. It serves as an invaluable resource for institutional animal care and use committees, which attempt to balance the welfare of farm animals and the needs of those working to improve animal agriculture.     

Rating vs. coding in animal personality research

Animal personality research has become increasingly popular over the past few decades. The two main methods used to examine individual differences in animals are rating and coding. The rating method involves human scoring of an animal's behavioral tendencies along various behavioral dimensions, such ratings are typically based on the human rater's experience with the animal. The coding method also requires humans to score an animal's behavior, but differs in that the scoring is based on the animal's immediate behavior in a specific context. This brief report describes the use of both the rating and coding methods to examine personality within a group of 10 Garnett's bushbabies (Otolemur garnettii). The results indicated that individual personalities do exist in bushbabies, but also suggested that the rating method is heavily influenced by the rater's experience with an animal. Consequently, it is important that the nature of the rater's interactions with the target animals be considered when using the rating method to assess animal personality.
