Animals need sufficient space to ensure physical health and to permit the performance of important behaviors. The effects of spatial restriction will increase with duration of confinement. In addition, diurnal rhythms are relevant. Animals may often require only sufficient space to rest comfortably but, at certain periods, additional space will be required for the performance of comfort, foraging, social or exploratory behavior. The spatial needs of unassuming animals such as chickens and rodents have been assessed using many approaches. First, animals can be housed at relevant allowances and a broad range of measures of health, behavior, physiological status and immune function taken to assess overall welfare. Second, the behavior of animals can be observed after spatial restriction is removed. A significant rebound in behavior performance would indicate that this behavior was being prevented by confinement. Third, the strength of animals' choices for additional space can be examined. Evidence from all three approaches showed that the extreme spatial confinement experienced by laying hens in conventional battery cages resulted in poor welfare, helping to secure a phase-out of conventional cages in Europe by 2012. It has been more difficult to establish optimum space allowances for species kept under less extreme restriction, such as laboratory mice and rats. No consistent effects on welfare were found when inbred and outbred mice were housed at 60, 100 or 167 cm2/mouse. In contrast, sleep disruption was increased when young rats housed were housed at higher stocking densities. Finally, assessment of optimum spatial allowance (stocking density) for animals housed in large groups, is complicated by complex interactions between enclosure size and group number.  相似文献

Since the establishment of the Exhibited Animals Protection Act, 1986 in New South Wales (NSW), a number of standards have been developed to help regulate the animal exhibition industry, to improve the industry's professionalism and to satisfy society's desire for exhibited animals to be cared for appropriately. The task of setting such standards is a difficult one. Due to the diversity of animals and the complexities of their needs, the process in NSW depends on regulators consulting with 2 major interest groups: the animal exhibition industry and the animal welfare lobby. Both groups claim to have animals' interests at heart but there are also differences of opinion between the groups and within each group. Science-based information that could assist in solving such disputes is often unavailable. This review of the standards creation process in NSW shows that something akin to the wisdom of Solomon is often required. The NSW regulators have addressed the deficiency of information about captive animal spatial requirements by considering the space required to carry out particular behaviors. A recent conflict over space requirements for zoo elephants is used to illustrate this approach. Other agencies involved in setting standards for exhibited animals can benefit from the NSW experience as they face similar difficulties. Interest groups, with a greater appreciation of the process, will hopefully support the acquisition of more science-based information.  相似文献

Public and consumer pressure for assurances that farm animals are raised humanely has led to a range of private and public animal welfare standards, and for methods to assess compliance with these standards. The standards usually claim to be science based, but even though researchers have developed measures of animal welfare and have tested the effects of housing and management variables on welfare within controlled laboratory settings, there are challenges in extending this research to develop on-site animal welfare standards. The standards need to be validated against a definition of welfare that has broad support and which is amenable to scientific investigation. Ensuring that such standards acknowledge scientific uncertainty is also challenging, and balanced input from all scientific disciplines dealing with animal welfare is needed. Agencies providing animal welfare audit services need to integrate these scientific standards and legal requirements into successful programs that effectively measure and objectively report compliance. On-farm assessment of animal welfare requires a combination of animal-based measures to assess the actual state of welfare and resource-based measures to identify risk factors. We illustrate this by referring to a method of assessing welfare in broiler flocks. Compliance with animal welfare standards requires buy-in from all stakeholders, and this will be best achieved by a process of inclusion in the development of pragmatic assessment methods and the development of audit programs verifying the conditions and continuous improvement of farm animal welfare.  相似文献

OBJECTIVE: To provide a rational framework for the scientific assessment of welfare and to use this framework to assess the welfare implications of issues relevant to the Australian egg industry. PROCEDURE: A well-accepted approach to the assessment of animal welfare, based on assessing how well the animal is adapting, is described. This approach is used to consider the welfare implications of issues such as space, perches, nest boxes, dust baths, abrasive strips and non-cage housing systems. CONCLUSIONS: The role of science in the welfare debate is to provide biological facts and thus it is important to separate welfare and ethics. The welfare of an animal in response to a housing system or husbandry procedure can be assessed by evaluating how much has to be done by the animal in order to cope and the extent to which the coping attempts are succeeding. Using this approach there is evidence for improved welfare from increasing space in cages, based on reduced aggression, corticosterone concentrations and mortalities and increased production, and for incorporating perches, based on the reduction in injuries at depopulation. Similar evidence for the inclusion of dust baths and nest boxes is lacking. The data on abrasive strips are equivocal with recommendations from overseas for their inclusion, whereas some local data have shown an increase in mortality can occur. Similarly, the data on non-cage systems are equivocal. The data on bone strength suggest improved fitness in non-cage systems, the data on stress suggest fitness may be better, similar or worse in non-cage systems, and the limited data on immunology suggest fitness may be worse in non-cage systems than in conventional cages.  相似文献

Scientific interest in farm animal welfare has grown rapidly in recent years because consumers increasingly demand that farm animals are reared, transported, and slaughtered in a humane way. Additionally, nutrition emerges as an important aspect of welfare since in most codes of recommendations for the welfare of animals, adequate nutrition is one of the primary requirements to be satisfied. We submit that in many cases domestic animals are provided with diets that, even when abundant and nutritious, are not necessarily adequate to foster the welfare of animals. The monotonous diets fed in confinement (total mixed rations) and on pasture (monocultures) often contain excesses of nutrients, nutrient imbalances, and toxins that adversely influence animal welfare. How much of any food an animal can eat will depend on the other foods it consumes, because at the biochemical level, nutrients and toxins interact one with another—nutrients with nutrients, nutrients with toxins, and toxins with toxins. Food intake and preference also depend on differences in how individual animals are built morphologically and how they function physiologically, and marked variation is common even among closely related animals relative to the needs for nutrients and tolerance to toxins. An integral part of an animal's ability to meet its particular nutritional requirements and consume substances that improve health depends on having a variety of foods available so each animal can select a diet that best meets its homeostatic needs. Food choice may also offer animals a means to cope with toxins, as certain food combinations have the potential to ameliorate the negative effects of toxins. We suggest that the availability of alternatives may not only contribute to maintain homeostasis but also reduce levels of stress. Thus, food choice is necessary for individual animals to have freedom to express their normal behaviors. We contend this freedom enables the uniqueness of individuals to be manifest, thereby promoting animal welfare and performance and increasing profitability of the people who manage animals.  相似文献

Sweden has a long history of detailed and progressive legislation related to animal welfare for laboratory, farm and companion animals. Previously, these issues have been the responsibility of the Swedish Board of Agriculture (SBA). As a growing proportion of the public opinion and the political establishment felt that the animal welfare related issues were not given proper attention at the SBA, a political decision was recently made to separate animal housing, management and welfare from the SBA and create an independent Animal Welfare Agency. This Agency was formally launched on January 1st 2004. The government has commissioned the Agency to improve animal welfare by evaluating, enforcing and developing legislation. The agency should consider scientific evidence when writing new legislation. Also, the Agency incorporates an external Animal Welfare Council, which, among other things, discusses ethical aspects in relation to existing or proposed legislature. The new Agency must deal with a diversity of public expectations. Animal rights groups have high expectations regarding new and stricter legislation, for example related to fur animals, while some farmers fear that production aspects may be completely lost in discussions about improving welfare standards for farm animals.  相似文献

To know how to care for animals, one must understand their needs. Physiologic and safety needs of farm animals are reasonably well fulfilled. Behavioral needs have yet to be determined and used as bases for animal care. The concept of the welfare plateau is important for the design and operation of facilities for agricultural animals. Current issues in the care of farm animals include standard agricultural practices, stockmanship and the human-animal bond, and standards of design for animal-production equipment.  相似文献

In the last years animal welfare has assumed an increasing interest in our society, influencing legislation to enact many provisions aimed at the protection of animals. Along with increased consumer awareness of the need to maintain ethically acceptable conditions of raised animals, scientists too have begun to investigate the conditions of animal welfare, the tools for its evaluation and for its improvement. Although there are many advances in knowledge, much remains to be investigated concerning many species considered "minor", that is, camels and dromedaries. Dromedaries, recently, have attracted the interest of some breeders following the results of studies concerning the nutritional and therapeutic properties of their products ‐ milk in particular ‐ that make them ideal for some particular categories of consumers, such as diabetics, obesity sufferers, lactose‐intolerant subjects, menopausal women and so on. Considering their use in dairy husbandry, dromedaries are reared under intensive and/or semi‐intensive systems with the resulting emergence of specific needs, which should be fulfilled in order to have appropriate welfare. This paper's purpose is to give practical elements in order to find out dromedary welfare standards, promoting a comprehensive set of regulations on welfare, care and protection of this animal.  相似文献

Dental, oral, and maxillofacial diseases are some of the most common problems in small animal veterinary practice. These conditions create significant pain as well as localized and potentially systemic infection. As such, the World Small Animal Veterinary Association (WSAVA) believes that un- and under treated oral and dental diseases pose a significant animal welfare concern. Dentistry is an area of veterinary medicine which is still widely ignored and is subject to many myths and misconceptions. Effective teaching of veterinary dentistry in the veterinary school is the key to progression in this field of veterinary medicine, and to the improvement of welfare for all our patients globally. These guidelines were developed to provide veterinarians with the information required to understand best practices for dental therapy and create realistic minimum standards of care. Using the three-tiered continuing education system of WSAVA, the guidelines make global equipment and therapeutic recommendations and highlight the anaesthetic and welfare requirements for small animal patients. This document contains information on common oral and dental pathologies, diagnostic procedures (an easily implementable and repeatable scoring system for dental health, dental radiography and radiology) and treatments (periodontal therapy, extractions). Further, there are sections on anaesthesia and pain management for dental procedures, home dental care, nutritional information, and recommendations on the role of the universities in improving veterinary dentistry. A discussion of the deleterious effects of anaesthesia free dentistry (AFD) is included, as this procedure is ineffective at best and damaging at worst. Throughout the document the negative effects of undiagnosed and/or treated dental disease on the health and well-being of our patients, and how this equates to an animal welfare issue, is discussed.  相似文献

The objective of this review is to consider the ethics of stockmanship, particularly from the perspective of the nature and extent of the duties of stockpeople to their farm animals. It will consider what science tells us about the impact of stockmanship on the animal, particularly the welfare of the farm animal. The effects of human-animal interactions on the stockperson will also be considered, since these interactions affect the work performance and job satisfaction of the stockperson and thus indirectly affect animal welfare. Animal ethics is broader than animal welfare and includes economic as well as philosophical, social, cultural and religious aspects. This paper is predicated on the view that farm animals can suffer, and that animal suffering is a key consideration in our moral obligations to animals. Housing and husbandry practices affect farm animal welfare and thus farmers and stockpeople have a responsibility to provide, at minimum, community-acceptable animal housing and husbandry standards for their animals. The farmer's or stockperson's attitudes and behaviour can directly affect the animal's welfare and thus they also have a responsibility to provide specific standards of stockmanship for these animals. However, research suggests that the behaviour of some stockpeople is not as correct as it might be. Such situations exemplify the inevitably unequal human - domestic animal relationship, and this inequality should be considered in analysing the boundary between right and wrong behaviour of humans. Thus ethical discussion, using science and other considerations and involving stockpeople, livestock industries, government and the general public, should be used to establish and assure acceptable stockperson competencies across the livestock industries. Training programs targeting the key attitudes and behaviour of stockpeople presently offer the livestock industries good opportunities to improve human-animal interactions.  相似文献

OBJECTIVE: To provide an integrated view of relationships between assessment of animal welfare. societal expectations regarding animal welfare standards, the need for regulation, and two ethical strategies for promoting animal welfare, emphasising farm animals. APPROACH: Ideas in relevant papers and key insights were outlined and illustrated, where appropriate, by New Zealand experience with different facets of the welfare management of farm animals. CONCLUSIONS: An animal's welfare is good when its nutritional, environmental, health, behavioural and mental needs are met. Compromise may occur in one or more of these areas and is assessed by scientifically-informed best judgement using parameters validated by directed research and objective analysis in clinical and practical settings. There is a wide range of perceptions of what constitutes good and bad welfare in society, so that animal welfare standards cannot be left to individual preferences to determine. Rather, the promotion of animal welfare is seen as requiring central regulation, but managed in a way that allows for adjustments based on new scientific knowledge of animals' needs and changing societal perceptions of what is acceptable and unacceptable treatment of animals. Concepts of 'minimal welfare', representing the threshold of cruelty, and 'acceptable welfare', representing higher, more acceptable standards than those that merely avoid cruelty, are outlined. They are relevant to economic analyses, which deal with determinants of animal welfare standards based on financial costs and the desire of the public to feel broadly comfortable about the treatment of the animals that are used to serve their needs. Ethical strategies for promoting animal welfare can be divided broadly into the 'gold standard' approach and the 'incremental improvement' approach. The first defines the ideal that is to be required in a particular situation and will accept nothing less than that ideal, whereas the second aims to improve welfare in a step-wise fashion by setting a series of achievable goals, seeing each small advance as worthwhile progress towards the same ideal. 'Incremental improvement' is preferred. This also has application in veterinary practice where the professional commitment to maintain good welfare standards may at times conflict with financial constraints experienced by clients.  相似文献

Departments of animal sciences must be relevant to a society in which a small number of people can raise almost all the food animal products needed. The declining number of people involved in animal agriculture has decreased enrollment of students interested in food animals in many departments of animal science. However, several departments welcomed students from a diverse background and began research on animals other than food animals. In many states, the undergraduate enrollment is made up primarily of students interested only in companion animals. A benefit of this is that we have recruited new students into animal agriculture and they have gone on to excellent careers. We have a new challenge now: how to maintain and expand the efforts in teaching, research, and outreach of companion animal science. Departments wishing to expand in teaching have examples of successful courses and curricula from other departments. Some departments have expanded their teaching efforts across their own university to teach about pets to a wider audience than their own majors; other departments can follow. In research, a small number of faculty have been able to establish extramurally funded projects on pets, including horses. But it will be difficult for more than a handful of departments to have a serious research effort in dogs, cats, birds, fish, or exotic animals. Departments will have to make a concerted effort to invest in such endeavors; joint ventures with other universities and colleges of veterinary medicine (or medicine) will probably be required. Funding sources for "traditional" efforts in nutrition, reproduction, and physiology are small and inconsistent; however, with the progress of the equine, canine, and feline genome projects, there should be opportunities from federal funding sources aimed at using animal models for human health. In addition, efforts in animal behavior and welfare can be expanded, perhaps with some funding from private foundations or animal-supportive organizations.  相似文献

Colleges and universities have an obligation to teach the basis of animal husbandry and welfare and must prepare students so that they can respond effectively to challenges by proponents of the animal welfare and animal rights movements. Veterinary curricula must now contain formal instruction in professional ethics and humane stewardship of animals for accreditation by the American Veterinary Medical Association. It is helpful if students have an understanding of farm animal behavior, stress physiology and methods of assessing welfare prior to learning about the animal welfare/rights movement's philosophies and issues. A review of early judicial practices, "classical" Judeo-Christian philosophy, the philosophy of Rene Descartes, Jeremy Bentham, Albert Schweitzer, and current philosophers and the entertainment media places the movements in perspective. Students should be familiar with such concepts as the mind-body controversy, equality of suffering, self-awareness or intelligence, and speciesism. After acquiring an appreciation of the basics, a knowledge of the issues facing animal agriculture and the arguments for and against each issue are necessary. Graduates of colleges of agriculture need to realize the potential effects the movements can have and take the initiative to improve the image of animal agriculture.  相似文献

Ideas within the animal welfare science arena have evolved continuously throughout the last 30 years, and will continue to do so. This paper outlines some of these developments. These included reformulation of the five freedoms concept into the five domains of potential welfare compromise. This accommodated weaknesses in the former by distinguishing between the physical/functional and the mental factors that contribute to an animal's welfare state. This development reflected a rising scientific acceptance that the mental experiences of animals were legitimate foci for study and highlighted that what the animal itself experiences represents its welfare status. Initially, most concepts of animal welfare emphasised predominantly negative subjective experiences, such as thirst, hunger and pain, and negative affective states or feelings including anxiety, fear and boredom, but today positive experiences or emotions such as satiety, vitality, reward, contentment, curiosity and playfulness are also considered to be important. During the same period, the focus shifted from evaluating the impacts of individual mental subjective experiences or emotions towards seeking a more comprehensive, multifactorial understanding. The five domains concept was specifically designed to achieve this. Subsequent notions about quality of life (QoL) had the same objective, and emphasised the importance of positive experiences. However, some approaches to QoL assessment relied heavily on empathetic speculation about what animals may experience subjectively and this raised concerns about inappropriate anthropomorphic projections. Such pitfalls may be minimised when informed personnel rigorously apply objectively based methodologies to QoL assessments limited to a short time frame. It is clear that both formal and somewhat less formal QoL assessments of this type are already used to guide decision-making about the ongoing care and therapeutic management of animals on a daily basis. However, application of the recently introduced concepts of 'a life not worth living', 'a life worth avoiding', 'a life worth living' and 'a good life' is problematical, because extending the assessment time scale to the whole of life is attended by a number of as yet unresolved difficulties. Accordingly, their value in the practical management of animals is limited so that, at present, reliance on the minimum standards and recommendations for best practice outlined in codes of practice or welfare will continue to be necessary and worthwhile. Nevertheless, these concepts have value in providing a contextual theme that strongly focuses attention on the promotion of a lifelong QoL with an overall balance that is positive.  相似文献

The paper discusses central moral issues raised by the applications of advanced biotechnology to animal agriculture and introduces the major ethical concepts and principles of animal bioethics. It is argued that biotechnology enables human beings to transform animals according to human needs, which blurs the boundary between humans and non-human animals in moral and biological sense. The more humans change animals, the more responsible humans are for the welfare of the animals and the greater their moral obligations. The paper introduces the main ethical approaches to animal welfare, traces the philosophical roots of animal ethics in the Judeo-Christian tradition and discusses the views of classical and contemporary ethicists such as Kant, Bentham, Mill, Peter Singer and Tom Regan. The paper explores the concept of animal welfare, suffering and rights, and the values behind Animal Liberation. Special attention is given to the animal welfare issues posed by cloning, genetic engineering and patenting of living organism. For each technology, actual or potential risks to animal welfare are identified and their moral implications are outlined. It is noted that the traditional moral principles of animal welfare, animal interests and animal rights are inadequate as means for evaluating the morality of certain advanced technologies because the technologies can change the animals in profound ways that make animal awareness too limited to give rise to claims about welfare, interests or rights. The principle of animal integrity is endorsed as an alternative better suited for evaluating the morality of advanced biotechnology.  相似文献

Blood collection from small exotic pocket pets can be difficult to achieve. The individual collecting the blood must know both the anatomy and behavior of the species to obtain suitable amounts of blood for diagnostic testing. Given the animals' small size, it is often difficult to collect large volumes of blood. A clinician serious in developing an exotic small mammal practice should understand the limitations of blood sample collection and the risks involved with the procedure. Unlike domestic animals, these pets are often not comfortable with being handled and are often prone to induced complications when presented to a veterinary clinic and restrained for examination. For some cases, the clinician will have to determine if the risk of getting the sample is better achieved by anesthetizing the patient, and if doing so will have a detrimental effect on the animal. One will also need to consider the effect of the anesthetic versus the stress the restraint may have on the blood results.  相似文献

Veterinarians in the United States and abroad are faced with growing public concern for the welfare of animals, particularly those in production. To prepare veterinarians to exert the leadership expected by the public and industry, steps should be taken to provide instruction in animal welfare at veterinary colleges. The ultimate goal is to offer courses in animal welfare in a consistent manner on a global scale, utilizing existing expertise in an efficient and cost-effective manner. Given the intense curricula of veterinary schools and the scarcity of instructors trained in animal welfare, a nontraditional approach is needed to educate veterinary students in the United States and abroad in animal welfare. Michigan State University (MSU) is developing a graduate-level, online interactive course in animal welfare assessment. The course will approach the topic of animal welfare education from a holistic, multidisciplinary standpoint (encompassing ethics, economics, and behavior) and address issues important to the general public and the international community. The MSU course will draw on renowned international animal welfare experts, allowing students to receive high-quality education that would be difficult in any other circumstance. The course will bridge an important gap in the veterinary curriculum and offer a complete and congruous education in animal welfare to veterinarians worldwide. The MSU course will also serve as a model for collaboration in content assembly and course delivery, by using technology to leverage global expertise in the interests of educational equity. In addition to innovative technology, such as the use of Web-collaboration software to create the course, a variety of media that enable students to interact with the material will also be incorporated throughout the course. Thus, the course will not only utilize the Internet to provide access to high-quality material, but will also require the active participation of the student, which is needed for effective learning.  相似文献

The equine industries in Ireland are vibrant and growing. They are broadly classified into two sectors: Thoroughbred racing, and sports and leisure. This paper describes these sectors in terms of governance, education and training in equine welfare, and available data concerning horse numbers, identification, traceability and disposal. Animal welfare, and specifically equine welfare, has received increasing attention internationally. There is general acceptance of concepts such as animal needs and persons' responsibilities toward animals in their care, as expressed in the 'Five Freedoms'. As yet, little has been published on standards of equine welfare pertaining to Ireland, or on measures to address welfare issues here. This paper highlights the central role of horse identification and legal registration of ownership to safeguard the health and welfare of horses.  相似文献
