Effects of confinement and research needs to underpin welfare standards

Although there is no agreement on how to measure animal welfare, how to interpret some of the observed changes in behavior and physiology, and how much confinement of animals is acceptable, this has not stopped animal welfare standards from being set in the form of either voluntary or mandatory recommendations. Notwithstanding that there are gaps in knowledge about a number of farming practices, there is some emphasis by scientists, industry, politicians, and some animal welfare groups for any changes to welfare-related recommendations to be based on scientific evidence. This article discusses the related issues of confinement and its effects on farm animals, research gaps in the field of animal welfare, the development of welfare standards, and whether such standards should be underpinned by science. For some issues there is a general consensus, for example, that animals feel pain and have emotions and that animals' appearance and behavior are used by good farmers to recognize both the ‘normality’ and deviations from normal of their animals. However, these variables are difficult to measure or define. Nevertheless, if issues are considered important to animals' welfare, should difficulty of measurement or definition be a barrier to the creation of legislated standards? Thus, options for legislated standards include either comprehensive standards, some of which may be difficult to measure, similar to current legislation on cruelty to animals, or only a limited number of standards with targets that can be measured, some of which may have less relevance to welfare outcomes.     

Ethical stockmanship

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.     

Farm animal welfare: the five freedoms and the free market

This review addresses the scientific, ethical and economic factors that impact on the welfare of farm animals. Respect for animals within the food chain is considered within the context of an ethical matrix that affords respect according to the principles of wellbeing, autonomy and justice to consumers, farm animals, farmers and the living environment. The welfare of a farm animal depends on its ability to sustain fitness and avoid suffering. The responsibility of the farmer is to make provision for good welfare through good husbandry; he cannot ensure good welfare. Improvements to farm animal welfare can only come about within the context of the forces that drive the free market. In essence, consumers need to afford a greater extrinsic value to farm animals. The costs to farmers of legislation to impose higher animal welfare standards are substantial but the cost to consumers can be very small. The responsibility is therefore on the consumer to convert an expressed desire for higher welfare standards into an effective demand. A promising route to encourage and fulfil this demand is through welfare-based quality assurance schemes with quality control ensured by independent audit. At present, audit protocols are based largely on identification of the elements of good husbandry. Ultimately we need a further independent audit to ensure that the outcome of these perceived elements of good husbandry is, in fact, good animal welfare.     

Animal well-being and animal care

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.     

Protection of farmed camels (Camelus Dromedarius): Welfare problems and legislative perspective

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.     

Organic livestock production in Europe: aims,rules and trends with special emphasis on animal health and welfare

Organic farming in Europe has increased during the last decade but the market share is still relatively low with less than 3% of farmed arable land and an even smaller proportion of farm animal species raised in organic livestock production systems. In many aspects, the biological and ethological needs of animals in organic farming systems are better met than on conventional farms. Emphasis is placed on high standards in product quality, animal health and welfare. However, limitations due to the strict organic rules place high demands on management qualifications. Practical experience shows that organic livestock production is certainly no guarantee of good animal health and welfare. It is suggested to develop quality assurance programmes for process quality assessment to ensure a certain level of management standard. Epidemiological studies are needed to evaluate health risk factors for health and welfare problems in organic livestock production. The concept of organic animal farming can only fulfil the criteria for sustainability, if all requirements on animal health and welfare, together with product quality and ecological soundness, are strongly considered and controlled.     

Animal behavior and well-being symposium: Farm animal welfare assurance: science and application

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.     

Results of a national survey of US veterinary college faculty regarding attitudes toward farm animal welfare

OBJECTIVE: To examine attitudes toward farm animal welfare among veterinary college faculty. DESIGN: E-mail survey. STUDY POPULATION: 157 US veterinary college faculty with large animal or food animal emphasis. PROCEDURE: Veterinarians from 27 US veterinary colleges were contacted via e-mail and asked to complete a 7-page survey relating to farm animal welfare issues. Thirty-one percent of those contacted responded. RESULTS: 71% of respondents self-characterized their attitude toward farm animal welfare as "we can use animals for the greater human good but have an obligation to provide for the majority of the animals' physiologic and behavioral needs." An additional 19% of respondents were more concerned about animal welfare than was indicated by that statement, and 10% were less concerned about farm animal welfare than was indicated by that statement. Significant relationships among demographic variables and attitude scores were observed, including more concerned attitudes among females, those with more liberal political views, and those who cited lower religiosity. No relationship between attitude and age was observed. CONCLUSIONS AND CLINICAL RELEVANCE: Veterinary college faculty have the opportunity to impact many stakeholders within the animal agriculture industries (eg, future veterinarians and policy makers looking for a veterinary science perspective). Results indicated that a considerable level of concern toward farm animal welfare is present in this population. Although the process of change may not be rapid, it is likely that the influence of these respondents will factor heavily into enhancing farm animal welfare.     

Animal welfare: at the interface between science and society

The general concept of animal welfare embraces a continuum between negative/bad welfare and positive/good welfare. Early approaches to defining animal welfare were mainly based on the exclusion of negative states, neglecting the fact that during evolution animals optimised their ability to interact with and adapt to their environment(s). An animal's welfare status might best be represented by the adaptive value of the individual's interaction with a given environmental setting but this dynamic welfare concept has significant implications for practical welfare assessments. Animal welfare issues cannot simply be addressed by means of objective biological measurements of an animal's welfare status under certain circumstances. In practice, interpretation of welfare status and its translation into the active management of perceived welfare issues are both strongly influenced by context and, especially, by cultural and societal values. In assessing whether or not a given welfare status is morally acceptable, animal welfare scientists must be aware that scientifically based, operational definitions of animal welfare will necessarily be influenced strongly by a given society's moral understanding.     

Teaching animal welfare science, ethics, and law to veterinary students in the United kingdom

Teaching veterinary students about animal welfare science, ethics, and law has been identified as a priority of the veterinary curriculum. Suggested content for such a course, the stage at which it should be taught, and possible methods of teaching and assessing the subject have been outlined. Critically, such a course needs to address the quantification of the impact of humans on animals (welfare science), the analysis of our moral obligations (welfare ethics), and knowledge of minimum welfare standards (welfare legislation). A mixture of both teaching methods and assessment techniques is needed to ensure that sufficient skills and knowledge and a deeper understanding are achieved.     

Animal health and animal health care concepts changing over time

The term "animal health", in particular applied to herds and flocks of food animals, needs to be newly defined in the light of the growing societal concerns with modern husbandry systems and animal welfare. This paper deals with a definition of animal health, which is extended to the well being of the animals and to pre-harvest food safety aspects. The future activities of food animal veterinarians have to meet the new demands and societal expectations discussed in this paper.     

Supervision of rabbit husbandry--report of a public health veterinarian

Rabbits are wide spread farm animals and pets, which are kept in the most diverse areas. The evaluation of rabbit husbandries in regard to animal welfare legislation is often complicated by different and contradictory recommendations of various organisations, which should partly be revised. In the following article some regulations and guidelines are discussed. In addition, some aspects for the keeping of rabbits in accordance with their behavioural needs are outlined, some frequent shortcomings regarding the keeping of rabbits are described and possibilities for taking official measures are presented.     

Farm animal welfare research in interaction with society

Over the last 30 years concern about farm animal welfare has increased and has become a public issue in the Netherlands. Public discussion has stimulated research in this field, financed by both government and industry. Dutch society in general and consumers of animal products in particular, want to see high standards of welfare for production animals. Good animal welfare has gradually gained more impact in the total quality concept of the product. This will encourage scientists to continue to analyse the welfare status of animals and to come up with innovative solutions for the remaining problems. At ID-Lelystad much effort is put into farm animal welfare research. This research includes for example, the development of behavioural tests for quantifying and interpreting fear in cattle, investigations into the effects of dietary iron supply and a lack of roughage on behaviour, immunology, stress physiology, and pathology in veal calves, studies of the ontogeny of tail biting in finishing pigs and feather pecking in laying hens as well as evaluation of the welfare effects of automatic milking in dairy cows. The results of these projects contribute to concrete improvements in animal husbandry and expertise and support policy making and legislation. The animal industry as well as retailers should aim at the further implementation of this knowledge and to specify welfare standards to guarantee consumer acceptance of animal production.     

Training and Certification of Farm Animal Care in Teaching and Research Institutions

Fane animal worker training and certification programs are currently not available. Programs are needed for training and certification of farm animal workers in teaching and research facilities at universities and companies and on commercial farms. Consumers support farm animal welfare assurances. Although the focus of this paper is the development of programs for teaching and research institutions, commodity-based assurance programs and laboratory animal worker training programs provide models for future programs that could provide assurance of acceptable farm animal care. The Federation of Animal Science Societies (FASS) training tapes on the use of farm animals in teaching and research are a first step toward the development of a full menu of training products for farm animal care. The FASS Guide for the Care and Use of Agricultural Animals in Agricultural Research and Teaching (Ag Guide) should provide a template for science-based training materials for people who work with farm animals.     

Non-accidental injuries found in necropsies of domestic cats: a review of 191 cases

Animal cruelty is defined as a deliberate action that causes pain and suffering to an animal. In Brazil, legislation known as the Environmental Crimes Law states that cruelty toward all animal species is criminal in nature. From 644 domestic cats necropsied between January 1998 and December 2009, 191 (29.66%) presented lesions highly suggestive of animal cruelty. The main necroscopic finding was exogenous carbamate poisoning (75.39%) followed by blunt-force trauma (21.99%). Cats from 7 months to 2 years of age were the most affected (50.79%). In Brazil, violence is a public health problem and there is a high prevalence of domestic violence. Therefore, even if laws provide for animal welfare and protection, animals are common targets for violent acts. Within a context of social violence, cruelty toward animals is an important parameter to be considered, and the non-accidental lesions that were found are evidence of malicious actions.     

The relativity of ethical issues in animal agriculture related to different cultures and production conditions

Initiatives to incorporate European animal welfare standards in international trade agreements raise issues of ethical relativism: (1) in the Fulani pastoral system the harsh environmental conditions result in a strong mutual dependency of pastoralists and their animals. Thus, animal ethics is vital to ensure the survival of the pastoral family, framed as ethic of securing survival; (2) the magnitude of human intervention, investigated in the Indian smallholder crop-livestock production system keeping oxen for work, determines the farmer's responsibility for adequate handling of animals. The apt anticruelty ethic prohibits deliberate cruelty to animals and neglect; (3) in intensive animal agriculture, such as intensive poultry and pig production in Thailand, the traditional ethical concept is no longer applicable and a new ethic encoded in law that respects the animals' natures is needed; (4) local moralities, as illustrated with the case of the llama system in the Andean highlands, deserve adequate attention independent of the production system. Therefore, the issue of animal welfare should be regarded relative in the global context and a dialogue between the cultures is encouraged to advance ethical concerns in animal agriculture.     

The structure and regulation of the Irish equine industries: Links to considerations of equine welfare

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.     

The process of building a new governmental authority based on public demands for improved animal welfare

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.     

Is dietary choice important to animal welfare?

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.
