Surgical castration of young male piglets is an extremely common husbandry procedure in the United States swine industry, with nearly 100% of males castrated. The procedure is performed primarily to prevent the occurrence of boar taint in the meat and to reduce aggression as the animals age. No research has investigated the impact of surgical castration on the long-term mood states – also known as the affective state – of piglets, but it has been proven to cause both acute and chronic pain that can last up to 4 days, modify piglet behavior, and reduce weight gain. Because of this, feasible approaches for pain alleviation are needed. A hinderance to this is that currently no analgesics are approved for piglets. In addition, we need validated, practical methods to recognize pain in piglets in order to help researchers, veterinarians, and caretakers to identify the need for analgesics. One useful tool for this could be the Piglet Grimace Scale, which has previously been validated in this context, but is not widely applied. The current lack of analgesic use during castration may be cause for concern for consumers, however little is known about the public's knowledge on the industry's practices. Therefore, the thesis' objectives are to (1) assess the impact of surgical castration on pain and affective states, (2) determine people's ability to recognize pain expression after surgical castration, and (3) get insights into public perception of swine industry practices. In Chapter 3, we assessed the impact of surgical castration and practical pain alleviation methods during and after castration on piglets' short and long-term affective states and activity levels. Piglets were surgically castrated, castrated with analgesics, or sham-handled at 3 days of age. Data on piglets' activity (using accelerometers), tails (affective states), and grimaces (pain expression) were collected for 1, 6, and 24 hours after castration treatments while piglets were in their home pens. An attention bias test was then performed in week 1 and 12 to assess anxiety (an affective state). Home pen activity after castration treatments suggested that there was a positive impact of using analgesics. The piglets' behavior (eating) and activity during the attention bias test at week 1 suggest a negative impact of castration on affective states. The differences observed in week 1 were no longer found in week 12, suggesting that any impact of surgical castration at 3 days of age on affective states are no longer detectable at 12 weeks of age. In Chapter 4, through an online survey we investigated the validity and reliability of Piglet Grimace Scale ratings applied by swine industry professionals and the general public, to assess its potential utility in non-research settings. The survey contained a training, followed by 9 piglet images showing facial expressions immediately after castration or sham-handling. Both response groups were able to recognize pain in castrated piglets. However, both response groups overestimated pain experience compared to trained experts, suggesting more training may be necessary. Nevertheless, overall, the scale can be widely applied by veterinarians, industry professionals and even members of the public. In Chapter 5, a survey provided initial insights into public knowledge and perceptions on castration and analgesia use and compared this to industry stakeholders. The results show that knowledge on industry practices was especially lacking for public respondents, but also for a minority of industry respondents, indicating opportunities for education and further research on the topic. / Master of Science / Surgical castration is performed on nearly every male piglet in the United States swine industry. Males are castrated to prevent the occurrence of boar taint and to reduce aggression. Boar taint is the unpleasant odor produced by the skatole and androsterone in the fat when the meat is prepared. It is unclear how this practice impacts piglet's long-term mood states (affective states), but we do know it causes pain, changes in behavior, and reduced productivity. Thus, we need feasible approaches for pain relief. However, there are currently no pain relievers approved for piglets. In addition, we need validated, practical methods to quantify pain in piglets in order to identify the need for pain relief. One useful tool is the Piglet Grimace Scale, which is validated but is not widely applied.

In Chapter 4, an online survey was used to investigate the Piglet Grimace Scale ratings applied by swine industry professionals and the general public.

Standard measures used in animal welfare assessments include animal-based measures obtained by observing animals, resource-based measures obtained by observing facilities, and management-based measures obtained by interviewing farmers and checking records. Animal welfare assessments are composed of a variety of measures and can be very different from each other. The objectives of the research presented in this thesis were to investigate inter-observer reliability of three swine welfare assessment programs (ACA™, PQA Plus®, and Welfare Quality®), and to determine the concordance of rankings across the 3 assessments. All assessments and all types of measures were found to be highly reliable. Moderate concordance was found for the rankings of farms across all three assessments. The lowest ranked farms were correlated, indicating that all assessments identified the farms with the lowest levels of animal welfare. Results of this study can be used to identify the best measures and revise current on-farm animal welfare assessments. / Canadian Swine Research and Development Cluster, a Growing Canadian Agri-Innovation Program – Canadian Agri-Science Cluster Initiative of Agriculture and Agri-Food Canada (AAFC); and the Ontario Pork Council

This thesis moves beyond the traditional approaches of how we ought to treat animals, and instead concentrates on the best strategy for preventing animal suffering in the farming industry. Chapter 1 considers the question of how we can know that animals feel pain, and concludes not only that it is rational to believe that they can, but also that this is a significant fact. Chapter 2 then analyses one possible strategy for helping to prevent animal suffering, namely demi-vegetarianism. For a number of reasons, however, this strategy is found to be flawed, therefore Chapter 3 analyses a second possible strategy, namely vegetarianism, and concludes that this is, in fact, the best strategy for helping to prevent animal suffering in the farming industry.

Welfare for captive animals in laboratory, farm, companion and zoo settings is difficult to assess and subject to interpretation. The perceived needs of animals change over time and according to budget, fashion and policy. The assessment of the value of environmental enrichment for captive animals is hampered by the lack of consistent, quantitative, objective and methodical research. Enrichment devices and other welfare improvement strategies lack long-term assessment or implementation. The concept of cognitive enrichment, or enabling captive animals to use their cognitive abilities to solve problems and meet challenges in their environment, is in the initial stages of development. Preliminary findings indicate that cognitive enrichment seems to be an effective method of improving captive animal welfare. In the research described in this thesis, several welfare measurement techniques including changes in activity budget, stereotypic behaviour and cognitive bias were compared and used to measure the effects of cognitive enrichment upon captive pigeons and dogs in order to obtain a useable cognitive enrichment paradigm that can be extrapolated to many types of captive animals. Key findings were that cognitive enrichment improved captive group-housed pigeon welfare and individually-kennelled dog welfare, indicated by significant changes in activity budget, increases in ‘optimism’, and reduction of stereotypic behaviour in subjects. Subjects used both low-tech and high-tech cognitive enrichments as intended and showed no sign of habituation. It is hoped that these findings will be used to improve captive animal welfare, and that the cognitive enrichment and cognitive bias paradigms developed will add to this field of research.

Master of Science / Department of Psychology / Richard J. Harris / Previous research has indicated that many factors influence the likelihood of using the central or peripheral routes of processing during exposure to a persuasive message, including involvement in the message. Previous research has generally focused on response involvement, which is based on outcome, while the focus of the present study is involvement based on personal investment. In the present study, 229 undergraduates were assessed on their trait empathy toward animals, and attitudes toward animals. They read a strong or weak persuasive message presented by either an attractive or less attractive writer. This design replicated previous findings by Bae (2008) on empathy and attitude change, and extended them by examining them experimentally, with a focus on issue-based involvement, which relies on moral or ego involvement. Participants were tested on several distinct DVs designed to indicate their change in attitude and behavior. Results varied for each DV, with source attractiveness predicting willingness to wear a button and display a bumper sticker, but with trait empathy predicting willingness to adopt a pet and vote to support a petition. The results imply that participants relied on different routes of processing depending on the DV, and that the role of emotion in issue involvement may inform advertisers in ways to effectively increase the likelihood of paying attention to a message.

Thesis (MPhil)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: 1. The purpose of the first chapter was to give a short introduction to the study. Philosophy is the search for wisdom; to know what a virtuous life is and to know what the morally correct thing to do is. Our lifelong relationship with animals, our attitudes towards them and the ways we treat them are some of the issues that beg philosophers to think. An important question in this regard is if it is morally correct to eat meat or should humans become vegetarian. To answer this question the „Animal Liberation‟ argument, as presented by Peter Singer, was critically analyzed. Does this argument balance our concern for animals with human interests? 2. To understand our attitude towards animals, reviews of the Judeo-Christian and philosophical traditions were done in Chapter 2. The different views related to these traditions were also discussed. The Judeo-Christian view is based on the interpretation of Genesis and the idea of human dominion. Philosophical views on the moral status of animals and moral consideration of animals can be classified in three categories namely indirect theories, direct-but-unequal theories and equal moral status theories. 3. The nature and extent of the current beef production debate was discussed in Chapter 3. The most important issues were the environmental impact of beef production, socio-economic and human health concerns as well as ethical issues related to the inhumane treatment of animals. It was then concluded that most attacks on beef production were biased and did not take context into account. 4. The „Animal Liberation‟ argument was critically analyzed from a logical perspective in Chapter 4, 5 and 6 by using the so called FRISCO approach – with emphasis on the Focus of the argument, Reasons given for the conclusion, the quality of Inferences, the Situation or context of the argument as well as the Clarity of the argument. This argument lacks objectivity and rationality. It includes a number of fallacies, false statements and emotional language. Ideas, concepts and principles were not applied consistently. The argument was therefore found to be unsound. 5. In Chapter 7 the conclusion was stated namely that the “animal liberation” approach could not formulate a sound argument for a vegetarian diet. The „Animal Liberation‟ argument was also unable to balance our concern for animals with human interests, in the process compromising human dignity and freedom. However, human attitudes towards animals and the treatment of animals need to be improved. / AFRIKAANSE OPSOMMING: 1. Die doel van die eerste hoofstuk was om ʼn kort inleiding tot die studie te gee. Filosofie is die strewe en soeke na wysheid; om te weet wat ʼn deugsame lewe is, en om te weet wat moreel korrek en aanvaarbaar is. Ons verhouding met diere, ons ingesteldheid teenoor diere, asook die manier hoe ons diere behandel, is slegs enkele van die kwessies wat filosowe dwing om daaroor na te dink. ʼn Belangrike vraag in die verband is die volgende: Is dit moreel aanvaarbaar om vleis te eet, of moet die mens ʼn vegetariese dieet volg? Om hierdie vraag te beantwoord word die “Animal Liberation”-argument, soos aangebied deur Peter Singer, krities ontleed. Is hierdie argument in staat om ons kommer oor die behandeling van diere met menslike belange te balanseer? 2. Om die mens se houding en ingesteldheid teenoor diere beter te verstaan, word ʼn oorsig van die Joods-Christelike en filosofiese tradisies in Hoofstuk 2 gedoen. Die verskillende sienings, wat verband hou met hierdie tradisies, word ook kortliks bespreek. Die Joods-Christelike siening is gebaseer op ʼn spesifieke vertolking van Genesis en die idee van menslike heerskappy. Die filosofiese sienings van die morele status, en gevolglik ook die morele inagneming van diere, kan in drie kategorieë, naamlik indirekte teorieë, direk-maar-ongelyke teorieë en die gelyke-morele-status teorieë, opgedeel word. 3. Die aard en omvang van die beesvleisproduksie-debat word in Hoofstuk 3 bespreek. Die belangrikste kwessies, onderliggend aan hierdie debat, het betrekking op die omgewingsimpak van vleisproduksie, sosio-ekonomiese en menslike gesondheidskwessies, asook etiese kwessies wat verband hou met die onaanvaarbare behandeling van diere. Die gevolgtrekking is dat die meeste aanvalle op vleisproduksie eensydig is en ook nie konteks in ag neem nie. 4. Die “Animal Liberation”-argument word in Hoofstuk 4, 5 en 6 krities ontleed vanuit „n logiese perspektief met behulp van die sogenaamde FRISCO-metode – waarin die klem val op die Fokus van die argument, Redes wat aangevoer word vir die konklusie, die gehalte van die afleidings, die Situasie of konteks van die argument, en die helderheid van die argument. Die gevolgtrekking is dat die argument nie objektief en rasioneel is nie, en gebuk gaan onder denkfoute, vals stellings en emosionele taal. Idees, konsepte en beginsel word ook nie konsekwent toegepas nie. Die argument is dus nie betroubaar nie. 5. In Hoofstuk 7 word die bevinding van die tesis gestel, naamlik dat die “animal liberation” benadering nie „n betroubare argument vir ʼn vegetariese dieet kon formuleer nie. Die argument was ook nie in staat om ons kommer oor diere met menslike belange te balanseer nie, en het in die proses menslike waardigheid en vryheid gekompromitteer. Die mens se houding en behandeling van diere, moet egter verander.

Uppsatsens syfte är att undersöka aktuella mediedebatter om köttkonsumtion ur ett djuretiskt perspektiv. Studien bygger på teorin om karnism och kritisk diskursanalys. Artikelsökningen gjordes genom Mediearkivet Retriever och avgränsades till de fyra största tidningarna i Sverige, Aftonbladet, Dagens Nyheter, Expressen och Svenska Dagbladet, från 2014 fram till idag. Det empiriska materialet bestod av 25 artiklar och ur dessa framkom fem diskurser: köttnormsdiskursen, djurrättsdiskursen, hälsodiskursen, marknadsdiskursen och miljödiskursen. Diskurserna gick ofta in i varandra och hade ofta fler än ett perspektiv. Studiens resultat visade att köttnormsdiskursen är den hegemoniska diskursen. Även om flera av artiklarna förespråkade konsumtion av enbart svenskt och ekologiskt kött, var köttkonsumtion ändå normen. Trots att köttkonsumtionen idag är rekordhög, var de flesta artiklarna oväntat eniga om att köttkonsumtionen måste minska drastiskt för hälsan, miljön och djurens skull. / The essay examines the recent media coverage of meat consumption from an animal ethical perspective. The study is based on the theory of carnism and critical discourse analysis. For the article search Mediearkivet Retriever was used and the search was limited to four main newspapers in Sweden, Aftonbladet, Dagens Nyheter, Expressen and Svenska Dagbladet. The time span was from the beginning of 2014 until today. The essays material consisted of 25 articles and from them five discourses were identified: The meat norm discourse, the animal rights discourse, the health discourse, the market economy discourse and the environmental discourse. The discourses often related to one another and often included more than one perspective. The study showed that the hegemonic discourse is the meat norm discourse. Although many of the articles were in favor of a drastic cut down of meat consumption, and suggested consumption of only Swedish and organic meat, the norm was still to consume meat. Although statistics show very high meat consumption, there seem to be a surprising consensus in the articles that meat consumption must decrease drastically, for health reasons, the environment and for the wellbeing of animals.

Nikola Šubrtová - Legal regulation of veterinary care Abstract My thesis is meant to be a humble attempt to describe rules or law governing animal care and animal protection in Czech Republic and in European Union as well. I tried to look closer at the concept on animal welfare as it reflects in czech legal order. This paper consists of nine chapters and the main laws analyzed in it are Act No. 166/1999 Coll., on veterinary care and Act No 246/1992 Coll., on the protection of animals against cruelty. My special focus was on animal protection during scientific procedures on animals and related regulations.
