One objection to xenotransplantation is that it will require the large-scale breeding, raising and killing of genetically modified pigs. The pigs will need to be raised in designated pathogen-free facilities and undergo a range of medical tests before having their organs removed and being euthanised. As a result, they will have significantly shortened life expectancies, will experience pain and suffering and be subject to a degree of social and environmental deprivation. To minimise the impact of these factors, we propose the (...) following option for consideration—ethically defensible xenotransplantation should entail the use of genetic disenhancementifit becomes possible to do so and if that pain and suffering cannot be eliminated by other means. Despite not being a morally ideal ‘solution’, itismorally better to prevent unavoidable pain until a viable non-animal alternative becomes available. (shrink)

The Netherlands is a small country with many people and much livestock. As a result, animals in nature reservations are often living near cattle farms. Therefore, people from the agricultural practices are afraid that wild animals will infect domestic livestock with diseases like Swine Fever and Foot and Mouth Disease. To protect agriculture (considered as an important economic practice), very strict regulations have been made for minimizing this risk. In this way, the practice of animal farming has been dominating the (...) practices of nature management completely. If, for instance, Foot and Mouth Disease strikes an agricultural area, all wild pigs and cattle living in the nearby nature reservations have to be killed, whether infected or not. This dominant position of one practice over the other has now become problematic. While the morality of the practice of nature management seems to be very different from the morality of agriculture and agriculture has become less important from an economic point of view, the public as well as those involved in nature management no longer seem to accept the dominant position of agriculture. Besides a literature study, we performed a field study with in-depth interviews with experts from both practices to analyze the dynamics of the internal moralities of both practices in the previous century, in order to clarify the contemporary situation. The conclusion was that the traditionally strong position of agriculture is not only weakening; it also appears that the internal values of agriculture are changing. The experts from both sides agreed that, in case of a disease outbreak, it is neither ethically justified nor necessary (because of the estimated low risk of disease transfer) to destroy the animals in nature reservations as a routine preventive measure. This is a major shift in morality. (shrink)

Nanotechnologies that have been linked to the possibility of enhancing cognitive capabilities of human beings might also be deployed to reduce or eliminate such capabilities in non-human vertebrate animals. A surprisingly large literature on the ethics of such disenhancement has been developed in response to the suggestion that it would be an ethically defensible response to animal suffering both in medical experimentation and in industrial livestock production. However, review of this literature illustrates the difficulty of formulating a coherent ethical debate. (...) Well structured arguments for disenhancement can be made on the basis of mainstream views on the basis of ethical obligations to animals, but these arguments have not been persuasive against the moral intuition that disenhancements are unethical. At the same time, attempts to ground these intuitions in a coherent philosophical doctrine have been plagued by logical fallacies and question begging assertions. As such, the debate over animal disenhancement forecasts an enduring conundrum with respect to the core question of transforming the nature of sentient beings, and this conundrum is logically independent of claims that relate either to the distinctive of human beings or to issues deriving from the emphasis on enhancement.

The combination of breeding for increased production and the intensification of housing conditions have resulted in increased occurrence of behavioral, physiological, and immunological disorders. These disorders affect health and welfare of production animals negatively. For future livestock systems, it is important to consider how to manage and breed production animals. In this paper, we will focus on selective breeding of laying hens. Selective breeding should not only be defined in terms of production, but should also include traits related to animal (...) health and welfare. For this we like to introduce the concept of robustness. The concept of robustness includes individual traits of an animal that are relevant for health and welfare. Improving robustness by selective breeding will increase (or restore) the ability of animals to interact successfully with the environment and thereby to make them more able to adapt to an appropriate husbandry system. Application of robustness into a breeding goal will result in animals with improved health and welfare without affecting their integrity. Therefore, in order to be ethically acceptable, selective breeding in animal production should accept robustness as a breeding goal. (shrink)

In recent years, humans’ ability to selectively modify genes has increased dramatically as a result of the development of new, more efficient, and easier genetic modification technology. In this paper, we argue in favor of using this technology to improve the welfare of agricultural animals. We first argue that using animals genetically modified for improved welfare is preferable to the current status quo. Nevertheless, the strongest argument against pursuing gene editing for welfare is that there are alternative approaches to addressing (...) some of the challenges of modern agriculture that may offer ethical advantages over genetic modification; namely, a dramatic shift towards plant-based diets or the development of in vitro meat. Nevertheless, we provide reasons for thinking that despite these possible comparative disadvantages there are important reasons for continuing the pursuit of welfare improvements via genetic modification.

The meteoric rise of CRISPR/Cas9 gene editing technology has ignited discussions of engineering agricultural animals to improve their welfare. While some have proposed enhancing animals, for instance by engineering for disease resistance, others have suggested we might diminish animals to improve their welfare. By reducing or eliminating species-typical capacities, the expression of which is frustrated under current conditions, animal diminishment could reduce or eliminate the suffering that currently accompanies industrial animal agriculture. Although diminishment could reduce animal suffering, there is a (...) widespread intuition that it would be wrong. One attempt to justify this intuition has been to claim that inhibiting the development of species-typical functions is wrong, even if it improves welfare. This has often been couched in terms of violating an animal’s dignity. I argue that the dignity objection to diminishment fails. In the first place, it fails to apply to some of the most troubling cases of diminishment, the creation of so-called animal microencepahlic lumps. In the second place, dignity views misplace the normative relevance of species norms; I argue that considerations from evolutionary biology should lead us to treat species norms - such as the possession of typical capacities - as merely a heuristic for rendering judgments about welfare. But diminishment cases are precisely the cases where the heuristic breaks down, and becomes a bias. I close my discussion with a sketch of my Historical Injustices Approach to animal ethics, and how it may help us vindicate our intuition that diminishment is wrong without appeal to species norms.

Cultured meat is a lab grown product that aims to tackle the cravings of omnivores who struggle to switch to a plant-based diet, while still being friendly to animals and the environment. Possibly, in time, the curiosity to apply this technology towards human meat production will emerge. However, when presented with the thought of eating cultured human meat potential consumers’ reaction greatly varies from pure disgust to indifference to excitement. This instinctive response indicates a lack of preformed judgements towards the (...) topic. Without a clear vision on the possibility of cultured human meat, scattered and uncertain regulations will fail to uphold paramount moral values. The risk is that we would either dig into this option out of excitement, or ban it without convincing motivations. The ethical theories of deontology and consequentialism can be followed to investigate this divisive issue. With an evaluation based on disgust I argue that the deontological perspective is mostly concerned with values of identity and humanness, while with a chain-reaction reasoning I argue that consequentialism would be concerned with health safety, privacy and equality. I conclude that cultured human meat is not acceptable. (shrink)

Some breeding technology applications are claimed to improve animal welfare: this includes potential applications of genomics and genome editing to improve animals’ resistance to environmental stress, to genetically alter features which in current practice are changed invasively, or to reduce animals’ capacity for suffering. Such applications challenge how breeding technologies are evaluated, which paradigmatically proceeds from a welfare perspective. Whether animal welfare will indeed improve may be unanswerable until proposed applications have been developed and tested sufficiently and until agreement is (...) reached on how to conceptualize animal welfare. Moreover, even if breeding technologies do improve animal welfare, they might be objected to on other ethical grounds. Ethical perspectives on earlier animal biotechnologies are relevant for today’s breeding technologies and their proposed applications, but may need reinterpretation. The current paper applies the concept of telos, which previously figured mainly in debates on classical genetic engineering, to genomic selection and genome editing aimed at improving animal welfare. It critiques current accounts of telos and offers an alternative conceptualization that applies to recently proposed applications of breeding technologies. This account rejects both removing the desire to pursue characteristic activities and altering animal bodies in ways that compromise their ability to perform such activities, but conditionally allows increasing robustness against environmental stress. Our account of telos enriches ethical debate on these breeding technology applications by insisting on the connection between the good life, an animal’s constitution, and its activities, thus countering reductive conceptions of welfare.

Martha Nussbaum argues that animals are entitled to a flourishing life according to the norm for their species. Nussbaum furthermore suggests that in the case of dogs, breed norms as well as species norms are relevant. Her theses capture both common intuitions among laypeople according to which there is something wrong with the breeding of “unnatural” animals, or animals that are too different from their wild ancestors, and the dog enthusiast’s belief that dogs departing from the norms for their breed (...) are tragic. I argue that the high diversity of the dog species and the ultimate arbitrariness of breed norms support the thesis that a conception of welfare must be tied to what the individual requires in order to flourish. In the second part of the paper, I discuss the implications that an individualized welfare conception has for the breeding of dogs for conformation shows, for the pet market and for the performance of various tasks for which we need working dogs.

In this paper I look at moral debates about animal disenhancement. In particular, I propose that given the particular social institutions in which such disenhancement will operate, we ought to reject animal disenhancement. I do this by introducing the issue of animal disenhancement and presenting arguments in support of it, and showing that while these arguments are strong, they are unconvincing when we look at the full picture. Viewing animal disenhancement in a context such as high intensity food production, we (...) see that the arguments in support of it fall short of other ethical considerations, leading me to conclude that the moral and pragmatic reasons weigh against animal disenhancement.

The conditions of life of many companion animals and the rate at which they are surrendered to shelters raise many ethical issues. What duties do we have towards the dogs that live in our society? To suggest answers to these questions, I first give four possible ways of looking at the relationship between man and dog: master–slave, employer–worker, parent–child, and friend–friend. I argue that the morally acceptable relationships are of a different kind but bears family resemblances to the latter three. (...) As dogs are beings with an interest in their wellbeing, society has certain duties towards the dogs, which can be translated in legislation. But human beings also have special responsibilities towards the dogs they take into their care. Such responsibilities entail caring for their emotional and physical welfare, but also ensuring a bond of trust, which should not easily be broken. (shrink)

Bernard Rollin argues that it is permissible to change an animal's telos through genetic engineering, if it doesn't harm the animal's welfare. Recent attempts to undermine his argument rely either on the claim that diminishing certain capacities always harms an animal's welfare or on the claim that it always violates an animal's integrity. I argue that these fail. However, respect for animal dignity provides a defeasible reason not to engineer an animal in a way that inhibits the development of those (...) functions that a member of its species can normally perform, even if the modification would improve the animal's welfare.

Articulating the public's widespread unease about animal biotechnology has not been easy, and the first attempts have not been able to provide an effective tool for navigating the moral permissibility of this research. Because these moral intuitions have been difficult to cash out, they have been belittled as representing nothing more than fear or confusion. But there are sound philosophical reasons supporting the public's opposition to animal biotechnology and these arguments justify a default position of resistance I call the Presumption (...) of Restraint . The Presumption of Restraint constitutes a justificatory process that sets out the criteria for permitting or rejecting individual biotechnology projects. This Presumption of Restraint can be overridden by compelling arguments that speak to a project's moral and scientific merit. This strategy creates a middle-of-the-road stance that can embrace particular projects, while rejecting others. The Presumption of Restraint can also serve as a model for assessing moral permissibility in other areas of technological innovation. (shrink)

Genetic engineering evokes a number of objections that are not directed at the negative effects the technique might have on the health and welfare of the modified animals. The concept of animal integrity is often invoked to articulate these kind of objections. Moreover, in reaction to the advent of genetic engineering, the concept has been extended from the level of the individual animal to the level of the genome and of the species. However, the concept of animal integrity was not (...) developed in the context of genetic engineering. Given this external origin, the aim of this paper is to critically examine the assumption that the concept of integrity, including its extensions to the level of the genome and the species, is suitable to articulate and justify moral objections more specifically directed at the genetic engineering of animals.

The Dutch policy objective of a fully sustainable livestock sector without mutilations by 2023 is not compatible with the routine practice of tail docking to minimize the risk of tail biting. To examine farmer attitudes towards docking, a telephone survey was conducted among 487 conventional and 33 organic Dutch pig farmers. “Biting” (of tails, ears, or limbs) was identified by the farmers as a main welfare problem in pig farming. About half of the farmers reported to have no tail biting (...) problems in their own herd. When farmers did report problems, they most often reported figures between 1 and 5 % of the animals. High incidences of tail biting were anticipated when trying to keep undocked pigs. Enrichment materials used in the conventional sector included mainly chains (52–63 % of the farms) and hanging rubber or plastic balls (22–30 %). Straw, sawdust, or wood shavings was hardly provided in conventional pig farming (2–3 %), in contrast to organic farming (88–100 % of farms). Conventional pig farmers feel a curly tail is not very important for sustainable pig farming. They consider enrichment to be less effective and tail docking to be less stressful for them and their piglets than their organic colleagues do. Pig farmers identified climate as a main risk factor for tail biting as opposed to enrichment. The objective of reducing routine tail docking requires solutions for dealing with tail biting problems at the farm level. In this process, transfer of scientific knowledge about enrichment materials and other measures to prevent and cure tail biting is critical, as is a change in farmer attitudes and awareness of the moral issues involved.

Pedigree dog breeding has been the subject of public debate due to health problems caused by breeding for extreme looks and the narrow genepool of many breeds. Our research aims to provide insights in order to further the animal-ethical, political and society-wide discussion regarding the future of pedigree dog breeding in the Netherlands. Guided by the question ‘How far are we allowed to interfere in the genetic make-up of dogs, through breeding and genetic modification?’, we carried out a multi-method case-driven (...) research, reviewing literature as well as identifying the perceptions of pedigree dog breeding of a variety of parties in the Netherlands. We examined what moral arguments and concepts different stakeholders, including breeders, veterinarians and animal protection societies, put forward when considering this question. While welfare arguments were often used as a final justification, we also frequently encountered arguments beyond welfare in practice, in particular the arguments that certain adaptations were unnatural, that they instrumentalised animals, or that they amounted to playing God. We argue that the way these arguments are employed points to a virtue ethical approach, foregrounding the virtue of temperance, as a balance between extreme positions was sought by our respondents in a variety of ways. Moreover, we argue against a rejection of unnaturalness arguments based on the naturalistic fallacy, as philosophers tend to do. We point out that unnaturalness arguments are related to people’s worldviews, including views on the proper human–animal relationship. We argue that such arguments, which we label ‘life-ethical’, should be the subject of more public discussion and should not be relegated to the private sphere. (shrink)

In order to determine whether current (or future) machines have a welfare that we as agents ought to take into account in our moral deliberations, we must determine which capacities give rise to interests and whether current machines have those capacities. After developing an account of moral patiency, I argue that current machines should be treated as mere machines. That is, current machines should be treated as if they lack those capacities that would give rise to psychological interests. Therefore, they (...) are moral patients only if they have non-psychological interests. I then provide an account of what I call teleo interests that constitute the most plausible type of non-psychological interest that a being might have. I then argue that even if current machines have teleo interests, they are such that agents need not concern themselves with these interests. Therefore, for all intents and purposes, current machines are not moral patients. (shrink)
