Report Of A Meeting On Contemporary Topics In Zebrafish Husbandry And Care, Nikki Osborne, Gregory Paull, Adam Grierson, Karen Dunford, Elisabeth M. Busch-Nentwich, Lynne U. Sneddon, Natalie Wren, Joe Higgins, Penny Hawkins
Ichthyology Collection
A meeting on Contemporary Topics in Zebrafish Husbandry and Care was held in the United Kingdom in 2014, with the aim of providing a discussion forum for researchers, animal technologists, and veterinarians from academia and industry to share good practice and exchange ideas. Presentation topics included protocols for optimal larval rearing, implementing the 3Rs (replacement, reduction, and refinement) in large-scale colony management, and environmental enrichment. The audience also participated in a survey of current practice relating to practical husbandry, cryopreservation, and the provision of enrichment.
The Impact Of Tickling Rats On Human-Animal Interactions And Rat Welfare, Megan Renee Lafollette
The Impact Of Tickling Rats On Human-Animal Interactions And Rat Welfare, Megan Renee Lafollette
Open Access Theses
Rats initially fear humans which can lead to negative affect, poor welfare, and difficult handling. Also, modeling and measuring positive affect states in rats can pose an additional challenge. Heterospecific play, or “tickling,” is a handling habituation technique that mimics rat rough-and-tumble play that is being used to study positive affect. It can also be used to reduce fear of human, improve welfare, and elicit a positive affect state. However, current studies implementing the technique in laboratory rats use a wide variety of protocols to achieve differential results. Unlike in laboratory environment, pet store rats experience high levels of novelty …
The Impact Of Sleep Disruption On Mouse Physiology, Behavior, And Welfare, Amanda L. Robinson-Junker
The Impact Of Sleep Disruption On Mouse Physiology, Behavior, And Welfare, Amanda L. Robinson-Junker
Open Access Theses
Laboratory mice are nocturnal, spending most of their daylight hours asleep. But they live in the diurnal world of human investigators and husbandry staff, who primarily work during this rest period. In humans, lack of sleep or sleep that occurs outside the normal circadian sleep period (as in shift work) has adverse effects. These include increased risk of cardiovascular disease, cancer, metabolic disorder, mood disorders, type II diabetes, and obesity. However, it is unknown if mice experience sleep disruption due to these human activities, and, if so, what the adverse effects may be. This is an important question, not only …
Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott
Rescued Goats At A Sanctuary Display Positive Mood After Former Neglect, Elodie F. Briefer, Alan G. Mcelligott
Elodie Briefer, PhD
Moods influence cognitive processes in that people in positive moods expect more positive events to occur and less negative ones (“optimistic bias”), whereas the opposite happens for people in negative moods (“pessimistic bias”). The evidence for an effect of mood on cognitive bias is also increasing in animals, suggesting that measures of optimism and pessimism could provide useful indicators of animal welfare. For obvious ethical reasons, serious poor treatments cannot be easily replicated in large mammals in order to study their long-term effects on moods. In this study, we tested the long-term effects (>2 years) of prior poor welfare …
Acoustic Analysis Of Cattle (Bos Taurus) Mother–Offspring Contact Calls From A Source–Filter Theory Perspective, Mónica Padilla De La Torre, Elodie F. Briefer, Tom Reader, Alan G. Mcelligott
Acoustic Analysis Of Cattle (Bos Taurus) Mother–Offspring Contact Calls From A Source–Filter Theory Perspective, Mónica Padilla De La Torre, Elodie F. Briefer, Tom Reader, Alan G. Mcelligott
Elodie Briefer, PhD
Cattle vocalisations have been proposed as potential indicators of animal welfare. How-ever, very few studies have investigated the acoustic structure and information encoded in these vocalisations using advanced analysis techniques. Vocalisations play key roles in a wide range of communication contexts; e.g. for individual recognition and to help coordinate social behaviours. Two factors have greatly assisted our progress in developing an understanding of animal vocal communication. Firstly, more rigorous call analysis methods allow us to describe the variation in the vocal parameters in unprecedented detail. Secondly, the adoption of the “source–filter theory” of call production links the acoustic structure of …
Aquatic Animals, Cognitive Ethology, And Ethics: Questions About Sentience And Other Troubling Issues That Lurk In Turbid Water, Marc Bekoff
Marc Bekoff, PhD
In this general, strongly pro-animal, and somewhat utopian and personal essay, I argue that we owe aquatic animals respect and moral consideration just as we owe respect and moral consideration to all other animal beings, regardless of the taxonomic group to which they belong. In many ways it is more difficult to convince some people of our ethical obligations to numerous aquatic animals because we do not identify or empathize with them as we do with animals with whom we are more familiar or to whom we are more closely related, including those species (usually terrestrial) to whom we refer …
Animal Welfare And Individual Characteristics: A Conversation Against Speciesism, Marc Bekoff, Lori Gruen
Animal Welfare And Individual Characteristics: A Conversation Against Speciesism, Marc Bekoff, Lori Gruen
Marc Bekoff, PhD
It seems impossible for a human being not to have some point of view concerning nonhuman animal (hereafter animal) welfare. Many people make decisions about how humans are permitted to treat animals using speciesist criteria, basing their decisions on an individual's species membership rather than on that animal's individual characteristics. Although speciesism provides a convenient way for making difficult decisions about who should be used in different types of research, we argue that such decisions should rely on an analysis of individual characteristics and should not be based merely on species membership. We do not argue that the concept of …
Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere
Cephalopods Are Best Candidates For Invertebrate Consciousness, Jennifer A. Mather, Claudio Carere
Animal Sentience
Insects might have been the first invertebrates to evolve sentience, but cephalopods were the first invertebrates to gain scientific recognition for it.
Culture, Reform Politics, And Future Directions: A Review Of China’S Animal Protection Challenge, Peter J. Li, Gareth Davey
Culture, Reform Politics, And Future Directions: A Review Of China’S Animal Protection Challenge, Peter J. Li, Gareth Davey
Peter J. Li, PhD
Incidents of animal abuse in China attract worldwide media attention. Is China culturally inclined to animal cruelty, or is the country’s development strategy a better explanation? This article addresses the subject of animal protection in China, a topic that has been ignored for too long by Western China specialists. A review of ancient Chinese thought asks whether China lacks a legacy of compassion for animals. The article then considers how China’s reform politics underlie the animal welfare crisis. Through its discussion of the welfare crisis impacting nonhuman animals in China, this paper sheds light on the enormity of the country’s …
Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li
Exponential Growth, Animal Welfare, Environmental And Food Safety Impact: The Case Of China’S Livestock Production, Peter J. Li
Peter J. Li, PhD
Developmental states are criticized for rapid “industrialization without enlightenment.” In the last 30 years, China’s breathtaking growth has been achieved at a high environmental and food safety cost. This article, utilizing a recent survey of China’s livestock industry, illustrates the initiating role of China’s developmental state in the exponential expansion of the country’s livestock production. The enthusiastic response of the livestock industry to the many state policy incentives has made China the world’s biggest animal farming nation. Shortage of meat and dairy supply is history. Yet, the Chinese government is facing new challenges of no less a threat to political …
On-Farm Qualitative Behaviour Assessment Of Dairy Goats In Different Housing Conditions, Lilia Grosso, Monica Battini, Françoise Wemelsfelder, Sara Barbieri, Michela Minero, Emanuela Dalla Costa, Silvana Mattiello
On-Farm Qualitative Behaviour Assessment Of Dairy Goats In Different Housing Conditions, Lilia Grosso, Monica Battini, Françoise Wemelsfelder, Sara Barbieri, Michela Minero, Emanuela Dalla Costa, Silvana Mattiello
Françoise Wemelsfelder, PhD
This study reports the results of the first investigation on the use of Qualitative Behaviour Assessment (QBA) in dairy goats, using a fixed-list of descriptors specifically developed for this species. It aimed to verify whether QBA can be reliably used by observers with different backgrounds to differentiate between the emotional states of goats kept under different environmental conditions. Two trained observers simultaneously assessed 16 dairy goat farms (8 “Housed” (H) farms, where animals were observed in free stall pens, and 8 “Pasture” (P) farms, where animals were observed in open ranges), using a list of 16 QBA descriptors that were …
Qualitative Assessment Of Animal Behaviour As An On-Farm Welfare-Monitoring Tool, Françoise Wemelsfelder, Alistair B. Lawrence
Qualitative Assessment Of Animal Behaviour As An On-Farm Welfare-Monitoring Tool, Françoise Wemelsfelder, Alistair B. Lawrence
Françoise Wemelsfelder, PhD
There is a growing need to monitor the health and welfare of farm animals, and to develop methods which do so efficiently and reliably. A crucial problem with current methods is the integration of separate measurements taken during farm visits into accurate judgements of an animal’s overall welfare state. This paper proposes that the qualitative assessment of animal behaviour may serve as an integrative methodology which could guide the interpretation of other, more detailed welfare measurements. Recent research has demonstrated qualitative behaviour assessment to be reliable and repeatable under controlled experimental conditions. The paper concludes with a discussion of ways …
How Animals Communicate Quality Of Life: The Qualitative Assessment Of Behaviour, F. Wemelsfelder
How Animals Communicate Quality Of Life: The Qualitative Assessment Of Behaviour, F. Wemelsfelder
Françoise Wemelsfelder, PhD
The notion ‘quality of life’ (QoL) suggests that welfare in animals encompasses more than just an absence of suffering; it concerns the quality of an animal’s entire relationship with its environment, of how it lives its life. Judgements of such quality are based on the integration of perceived details of how animals behave over time in different contexts. The scientific status of such judgements has long been ambiguous, but in recent decades has begun to be addressed by animal scientists. This paper starts with a brief review of qualitative approaches to the study of animal behaviour, which tend to address …
Are Domestic Pigs (Sus Scrofa Domestica) Able To Use Complex Human-Given Cues To Find A Hidden Reward?, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell
Are Domestic Pigs (Sus Scrofa Domestica) Able To Use Complex Human-Given Cues To Find A Hidden Reward?, Christian Nawroth, Mirjam Ebersbach, Eberhard Von Borell
Social Cognition Collection
Understanding human-animal interactions in livestock production systems is crucial for improving animal welfare. It is therefore of general interest to investigate how livestock animals obtain information from humans. By using an object-choice paradigm, we investigated whether domestic pigs (n = 4) are able to use a variety of human-given cues, such as different pointing gestures, to find a hidden food reward. In Experiment 1, an experimenter pointed towards a baited location in front of the pig while the extent of the protrusion of his hand from the upper body was varied. Pigs had problems using pointing gestures that did not …

Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom
Considering Animals’ Feelings: Précis Of Sentience And Animal Welfare (Broom 2014), Donald M. Broom
Animal Sentience
The concept of sentience concerns the capacity to have feelings. There is evidence for sophisticated cognitive concepts and for both positive and negative feelings in a wide range of nonhuman animals. All vertebrates, including fish, as well as some molluscs and decapod crustaceans have pain systems. Most people today consider that their moral obligations extend to many animal species. Moral decisions about abortion, euthanasia, and the various ways we protect animals should take into account the research findings about sentience. In addition, all animal life should be respected and studies of the welfare of even the simplest invertebrate animals should …
Linking Animal Ethics And Animal Welfare Science, Sue Donaldson, Will Kymlicka
Linking Animal Ethics And Animal Welfare Science, Sue Donaldson, Will Kymlicka
Animal Sentience
Broom (2014) argues that theories of animal ethics need to be better informed by the findings of animal welfare science. We agree, but argue that animal welfare science in turn may need to ask different questions. To date it has largely assumed that society will continue to treat domesticated animals as a caste group that exists to serve us, and that animal welfare is to be improved within that legal and political framework. We offer an alternative model of human-animal relations, and discuss what kind of animal welfare science it would require.
How Welfare Biology And Commonsense May Help To Reduce Animal Suffering, Yew-Kwang Ng
How Welfare Biology And Commonsense May Help To Reduce Animal Suffering, Yew-Kwang Ng
Animal Sentience
Welfare biology is the study of the welfare of living things. Welfare is net happiness (enjoyment minus suffering). Since this necessarily involves feelings, Dawkins (2014) has suggested that animal welfare science may face a paradox, because feelings are very difficult to study. The following paper provides an explanation for how welfare biology could help to reduce this paradox by answering some difficult questions regarding animal welfare. Simple means based on commonsense could reduce animal suffering enormously at low or even negative costs to humans. Ways to increase the influence of animal welfare advocates are also discussed, focusing initially on farmed …
What’S The Common Sense Of Just Some Improvement Of Some Welfare For Some Animals?, Liv Baker
What’S The Common Sense Of Just Some Improvement Of Some Welfare For Some Animals?, Liv Baker
Animal Sentience
The goal of Animal Welfare Science to reduce animal suffering is commendable but too modest: Suffering animals need and deserve far more.
Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan
Is Sentience Only A Nonessential Component Of Animal Welfare?, Ian J.H. Duncan
Animal Sentience
According to Broom (2014), animal welfare is a concept that can be applied to all animals, including single-celled organisms that are obviously not sentient. Such a stance makes it difficult to draw a connection between welfare and sentience, and that is the book’s downfall. Some excellent points are made about sentience and there are very good discussions on animal welfare. However, unless sentience is considered the essential component of welfare, any attempt to link the two phenomena will be unsuccessful — and that, indeed, is the case with this book.
Animal Welfare And Animal Rights, M.E. Rolle
Animal Welfare And Animal Rights, M.E. Rolle
Animal Sentience
This overview of Broom’s book, Sentience and Animal Welfare (2014), considers the role the book could play in the animal rights debate. In a thoroughly researched and objectively presented text, Broom lays out information that could place doubt in the minds of decision-makers. By highlighting not just the ways animals resemble humans, but also the ways humans resemble animals, Broom shines a light on a solidly grey area in the animal rights debate.
