Systems for evaluation of welfare on dairy farms.

Animal welfare is an essential component of dairy production and several systems exist to evaluate the welfare of dairy cows. Here, we review and compare three well-known systems that operate at farm level from around the world (FARM, Welfare Quality®, and The Code of Welfare) and discuss their advantages and limitations. Despite having some commonalities, the programs evaluate different elements. We also briefly review an emerging system (Integrated Diagnostic Welfare System) that might address some of the shortcomings of the existing systems, especially the possibility of automating the evaluation of animal well-being and identifying any cause of poor welfare. None of the aforementioned systems has been fully validated for their ability to assess animal welfare using independent measurements. The future holds increased attention around the well-being of dairy cows and increased use of sensing technologies. There is an urgent need for dairy welfare evaluation systems that are scientifically validated, holistic, and that can take advantage of the use of sensing technologies to continuously monitor animal welfare.

Not appropriate dinner table conversation? Talking to children about meat production.

Although Australians on average consume large quantities of meat, their attitudes to farm animal welfare are poorly understood. We know little about how farm animal production is discussed in Australian households or how children learn about the origins of meat. This study consisted of an online survey completed by 225 primary carers throughout Australia recruited through social media. Findings include that conversations about the origin of meat were generally stimulated by meal preparation within the home rather than visits to agricultural shows or similar activities. Parents preferred to initiate conversations with children about meat production before they were 5 years of age. Urban parents were more likely than rural parents to reveal that they were conflicted about eating meat and would be more empathetic to children who chose to stop eating meat. Rural parents were more likely than urban parents to feel that children should eat what they are given and that talking about meat is not a major issue. Both groups felt that it was important that children should know where their food comes from. The findings of this study suggest that parental attitudes to meat production and consumption influence conversations about meat origins with children.

Weighing the options for limiting surplus animals.

The unsustainability of many animal programs managed by zoos and aquariums has brought renewed attention to unresolved questions about various management strategies. Solving the "sustainability crisis" for many species will require housing more adults and producing more offspring than there are existing spaces in accredited zoos and aquariums. Careful reproductive management is central to addressing this challenge, but opinions differ about which management strategies are best for an individual, for a species, for an institution, or for a country or region. The primary options for limiting the number of animals that would be surplus to the population are to prevent reproduction or to euthanize. However, there is much misunderstanding about methods for controlling reproduction, in particular about contraceptives and species differences in their effects. Careful weighing of all the options is called for. Lifetime Reproductive Planning may help increase breeding success through careful reproductive management but cannot eliminate production of surplus animals. Limiting reproduction does not address the problem of animals already in the population. Despite best efforts and planning, consistently hitting target numbers for a population may never be achieved. Increasing capacity provides a temporary patch when targets are exceeded, but is not a long-term solution, since each generation potentially produces even more individuals needing even more space. Welfare considerations should be included in discussions of management euthanasia and its alternatives. Such discussions will be most productive if based on full awareness of the advantages and disadvantages of all the options. Zoo Biol. 35:183-186, 2016. © 2016 Wiley Periodicals, Inc.

Survey of U.S. zoo and aquarium animal care staff attitudes regarding humane euthanasia for population management.

The humane euthanasia of animals for population management, or culling, has been suggested as one possible tool for managing animal populations for sustainability, and recent, highly publicized euthanasia of zoo animals in Copenhagen has stimulated global conversation about population management in zoos. We conducted a nationwide survey of U.S. zoo and aquarium personnel, including keepers, managers, and leaders of AZA animal programs, to assess their overall attitudes regarding population management euthanasia. The surveyed populations were generally very aware of the concept of population management euthanasia. Managers and animal program leaders were more supportive of euthanasia than keepers. We found that regardless of role, men were more supportive of euthanasia than women. Those personnel who were aware of instances of population management euthanasia at their institutions before were more supportive of it than those who were not. Support for culling varied with the kind of animal being considered for it, with three general taxon acceptability groupings emerging. Education, tenure in the profession, taxonomic expertise, and whether or not the responder took the survey before or after the Copenhagen events were not strong predictors of attitudes. Overall, the surveyed populations were approximately evenly split in terms of being in favor of euthanasia, not supporting euthanasia, or being unsure. Most responders indicated that they would be more likely to accept culling if more information was provided on its rationale. These results will form the basis for further discussions on the role of humane euthanasia for population management. Zoo Biol. 35:187-200, 2016. © 2016 Wiley Periodicals, Inc.

Training to improve stockperson beliefs and behaviour towards livestock enhances welfare and productivity.

The principle that supervising and managing animals affects farm animal welfare is widely recognised within the livestock industries. However,the manner in which the stockperson affects animal welfare, both directly and indirectly, is probably not fully appreciated. Together with the opportunity to perform their tasks well, stockpeople require a range of well-developed husbandry skills and knowledge to effectively care for and manage farm animals. There are three main factors that can be considered to contribute to a stockperson's work performance: capacity, willingness and opportunity. Capacity includes variables such as skills, health, ability and knowledge, while willingness includes motivation, job satisfaction, attitude to the animals and work attitude, and opportunity includes working conditions, actions of co-workers and organisational policies and rules. This paper briefly reviews the influence of the stockperson on livestock welfare and productivity and the opportunities to improve the stockperson's performance through training. It is clear that there is a continuing need for livestock industries to train their personnel to effectively care for and handle their stock. Underestimating the role and impact of the stockperson will seriously risk the welfare and productivity of livestock. Indeed, the stockperson may be the most influential factor affecting animal handling, welfare and productivity. Furthermore, it is likely that, in the near future, both the livestock industries and the general community will place an increasing emphasis on ensuring the competency of stockpeople to manage the welfare of livestock.

The process of exiting vegetarianism: an exploratory study.

PURPOSE: The experience, reasons, and contexts associated with leaving vegetarianism were explored. METHODS: Interviews were conducted with a convenience sample of 19 ex-vegetarians and 15 continuing vegetarians. RESULTS: Exiting vegetarianism is similar to the process of leaving other important individual identities, including exiting diets containing meat. It is a process, not an event, and partially a response to inconvenience, particularly when the person's table companions were not vegetarians. Major life changes and declines in self-perceived health provided occasions to reassess life choices, including the vegetarian commitment. Ex-vegetarians interpreted their vegetarianism as a transition to a new, healthier diet. Including a comparison group of continuing vegetarians revealed that the ex-vegetarians were more likely to have become vegetarians as a result of concern about the well-being of animals and the environment, not animal rights, a value more difficult to compromise. CONCLUSIONS: Exiting processes show the five central food values of taste, health, time, cost, and social relationships undermine people's commitment to a diet chosen largely for moral reasons.

Could some people be wronged by contracting swine flu? A case discussion on the links between the farm animal sector and human disease.

This paper uses the imaginary case of Gemma, presented initially at the International Swine Flu Conference (London, March 2010), to discuss whether a nurse who disagrees with most ways in which animals are farmed would be wronged if she contracted swine flu. It is argued that the farm animal sector has contributed to the emergence of H1N1 flu, and that the sector in general contributes significantly to the burden of human disease. The aim of this paper is to promote debate on the question as to whether a range of systems used by the farm animal sector survive moral scrutiny in light of these concerns.

The concept of animal welfare at the interface between producers and scientists: the example of organic pig farming.

In organic farming animal welfare is one important aspect included in the internationally agreed organic principles of health, ecology, fairness and care (IFOAM 2006), reflecting expectation of consumers and farmers. The definition of organic animal welfare includes-besides traditional terms of animal welfare-'regeneration' and 'naturalness'. Organic animal welfare assessment needs to reflect this and use complex parameters, include natural behaviour and a systemic view. Furthermore, various parties with seemingly conflicting interests are involved, causing ethical dilemmas, such as the use of nose rings for outdoor sows (impaired animal welfare vs. destruction of humus). Solutions can only be found when foundational concepts are translated and applied to practical situations. On-farm animal welfare assessment and implementation of improvement strategies are increasingly relevant scientific areas. They combine on-farm welfare assessment, identification of key problem areas and connected risk factors. Constant communication between all parties is crucial for success. Animal health and welfare planning is one application of this approach, which was carried out on Austrian organic pig farms as well as organic dairy farms in seven European countries. The projects included welfare assessment, feedback and benchmarking as a tool for communication between farmers, advisors and scientists. Finally goals were set by the farmer and improvement strategies applicable to organic farming were implemented. This included prevention of disease by management strategies instead of routine treatment with pharmaceutical products. It appeared that next to problem structuring, multidisciplinary problem solving demands good communications skills to relate animal welfare science to value reflections.

A history of animal welfare science.

Human attitudes to animals have changed as non-humans have become more widely incorporated in the category of moral agents who deserve some respect. Parallels between the functioning of humans and non-humans have been made for thousands of years but the idea that the animals that we keep can suffer has spread recently. An improved understanding of motivation, cognition and the complexity of social behaviour in animals has led in the last 30 years to the rapid development of animal welfare science. Early attempts to define welfare referred to individuals being in harmony with nature but the first usable definition incorporated feelings and health as part of attempts to cope with the environment. Others considered that welfare is only about feelings but it is argued that as feelings are mechanisms that have evolved they are a part of welfare rather than all of it. Most reviews of welfare now start with listing the needs of the animal, including needs to show certain behaviours. This approach has used sophisticated studies of what is important to animals and has replaced the earlier general guidelines described as freedoms. Many measures of welfare are now used and indicate how good or how poor the welfare is. Naturalness is not a part of the definition of welfare but explains why some needs exist. In recent years, welfare has become established as one of various criteria used to decide on whether a system is sustainable because members of the public will not accept systems that cause poor welfare. The study of welfare has become part of the scientific basis upon which important political decisions are made.

The broiler breeder paradox: ethical, genetic and physiological perspectives, and suggestions for solutions.

1. Due to intensive selection, broiler chickens became the most efficient meat-producing animals because of their fast growth, supported by a virtually unlimited voluntary feed intake. These characteristics cause many problems in the management of broiler breeder hens because of the negative correlation between muscle growth and reproduction effectiveness. 2. This problem, namely the fast muscle growth versus reproduction health paradox, induces a second paradox, acceptable reproduction and health versus hunger stress and impaired welfare, because broiler breeder hens require dedicated programmes of feed restriction (1) to maximise egg and chick production and (2) to avoid metabolic disorders and mortality in broiler breeders. 3. Given that poultry selection is a global large-scale business and chickens are a prolific species, improvement in profit can only be obtained by selecting on feed conversion and/or for higher breast meat percentage, which will intensify the broiler-breeder paradox. 4. New feeding strategies are being studied, but it is questionable if the paradox can be solved by management tools alone. Because breeding and selection are long-term processes, involving animals, farmers, consumers, industry, environment etc., a more sustainable breeding goal needs to be determined by a multidisciplinary approach and an open debate between several actors in the discussion. 5. Using dwarf broiler breeder hens could be one alternative, because dwarf hens combine relatively good reproductive fitness with ad libitum feeding. Another possibility is to accept lower broiler productivity by assigning economic values to welfare and including integrity traits in an extended breeding goal.
