实验动物饲养和运输的伦理与福利

本文提出实验动物福利是人类应当给予实验动物的良好条件（正面因素）,主要体现在动物的饲养和运输等过程,以“5F”为基本理论;伦理则是人类给予动物实验处理（负面因素）时应遵循的原则,主要体现在动物实验过程中,以“3R”为基本理论.同时总结了实验动物饲养和运输过程的实际经验,从环境、笼具、垫料、密度、饲料和饮水、社会和行为需要、安乐死、运输等方面,介绍了保障实验动物福利的具体做法.     

Concepts of Animal Welfare in Relation to Positions in Animal Ethics

When animal ethicists deal with welfare they seem to face a dilemma: On the one hand, they recognize the necessity of welfare concepts for their ethical approaches. On the other hand, many animal ethicists do not want to be considered reformist welfarists. Moreover, animal welfare scientists may feel pressed by moral demands for a fundamental change in our attitude towards animals. The analysis of this conflict from the perspective of animal ethics shows that animal welfare science and animal ethics highly depend on each other. Welfare concepts are indispensable in the whole field of animal ethics. Evidence for this can be found by analyzing the structure of theories of animal ethics and the different ways in which these theories employ welfare concepts. Furthermore, the background of values underneath every welfare theory is essential to pursue animal welfare science. Animal ethics can make important contributions to the clarification of underlying normative assumptions with regard to the value of the animal, with regard to ideas about what is valuable for the animal, and with regard to the actions that should follow from the results of animal welfare science.     

Zoo Animal Welfare: The Human Dimension

ABSTRACT

Standards and policies intended to safeguard nonhuman animal welfare, whether in zoos, farms, or laboratories, have tended to emphasize features of the physical environment. However, research has now made it clear that very different welfare outcomes are commonly seen in facilities using similar environments or conforming to the same animal welfare requirements. This wide variation is almost certainly due, at least in part, to the important effects of the actions of animal care staff on animal welfare. Drawing mostly on the farm animal literature, we propose that this “human dimension” of animal welfare involves seven components: (1) positive human–animal interaction, (2) consistency and familiarity of keepers, (3) treating animals as individuals and taking account of their personalities, (4) the attitudes and personalities of keepers, (5) the keepers’ knowledge and experience, (6) the keepers’ own well-being, and (7) the influence of facility design on how keepers and others interact with the animals. We suggest that attention to these human factors provides major scope for improving the welfare of animals in zoos.     

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。     

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。     

Filling the Ark: Animal Welfare in Disasters

ABSTRACT

Populations of feral domestic cats and free-roaming, owned cats have increased throughout the United States, affecting wildlife and public health and warranting attention from a variety of management agencies. The contentious issue of feral cat management requires a greater understanding of public attitudes towards cats and preferences. We used an anonymous internet survey of randomly selected Athens-Clarke County, Georgia households to identify general public perceptions of domestic cats and preferences for cat management. We examined factors that may influence attitudes towards cats, and management including: knowledge about cats, experiences with cats and demographic variables. Results indicate that more residents have positive experiences with feral cats than negative, cat owners have greater knowledge of cats than non-cat owners, and animal welfare or conservation organization membership has a significant effect on attitudes towards cats. A majority of survey respondents agreed that more effective feral cat management is needed yet did not approve of trap-neuter-release (TNR) legislation recently passed in Athens-Clarke County. Logistic regression revealed that residents' attitudes were found to be more important than experiences or knowledge in supporting cat management legislation. Cat sanctuaries were found to be the most acceptable option to reduce feral cat populations (56%), followed by TNR (49%) and capturing and euthanizing cats (44%).     

Livestock Vehicle Accidents in Spain: Causes,Consequences, and Effects on Animal Welfare

Livestock vehicle accidents are rare but involve significant economic, human, and nonhuman farm animal losses. This study obtained information on the characteristics of accidents, the animals involved, and injuries to humans from newspaper reports about livestock vehicle accidents in Spain from January 2000 to December 2008. Most accidents involved pig transport (57%), followed by bovine (30%), poultry (8%), and sheep (5%). Driver mortality was not high (6%), and most accidents (76%) involved only the livestock vehicle, which often was overturned (64%) on a straight road transect (51%). Multivariate analysis of the data suggests 2 types of accidents, depending on the species transported. In the first cluster, 95.3% of the cases involved pig transport with articulated vehicles (60.5%). In the second cluster, 94.4% of the accidents involved small vehicles used for cattle transport (44.4%). The results of this study indicate that the characteristics of livestock vehicle accidents vary according to species. One of the main causes of accidents appears to be driver fatigue, which may be due to several factors such as intense workdays, poorly designed route plans, or high levels of pressure from companies.     

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.
