Evaluation Of Animal-Based Indicators To Be Used In A Welfare Assessment Protocol For Sheep, Susan E. Richmond, Françoise Wemelsfelder, Ina Beltran De Heredia, Roberto Ruiz, Elisabetta Canali, Cathy M. Dwyer

Françoise Wemelsfelder, PhD

Sheep are managed under a variety of different environments (continually outdoors, partially outdoors with seasonal or diurnal variation, continuously indoors) and for different purposes, which makes assessing welfare challenging. This diversity means that resource-based indicators are not particularly useful and, thus, a welfare assessment scheme for sheep, focusing on animal-based indicators, was developed. We focus specifically on ewes, as the most numerous group of sheep present on farm, although many of the indicators may also have relevance to adult male sheep. Using the Welfare Quality® framework of four Principles and 12 Criteria, we considered the validity, reliability, and feasibility of …

Risk Assessment Of Catch And Release, Rolf Erik Olsen, Tor Fredrik Næsje, Trygve Poppe, Lynne Sneddon, John Webb

Lynne Sneddon, PhD

The report was produced during most of 2009, and gives a state of art overview of current knowledge on the effects of catch and release practices on these fish species’ welfare, using accessible and peer reviewed published literature as basis for the assessment. Anecdotic and non-published reports have been used to a limited extent as they are regarded as untested or containing unverified statements. The Panel on Animal Health and Welfare discussed the full report in a meeting on the 9th of December, and gave its support to the conclusions drawn by the ad hoc-group. The report has concentrated on …

Pain In Farm Animals, L. U. Sneddon, Michael J. Gentle

Lynne Sneddon, PhD

This review will address how we can measure pain in farm animals and discuss the major causes of acute pain and also chronically painful conditions, and finally make suggestions for future improvements. Pain is a relatively difficult concept to define since it comprises both a physiological sensory and a psychological or emotional component. Pain is the subjective interpretation of nerve impulses induced by a stimulus that is actually or potentially damaging to tissues. The sensation of pain is a response to a noxious stimulus and should elicit protective motor (e.g. withdrawal reflex, escape) and vegetative responses (e.g. cardiovascular responses, inflammation). …

Equine Welfare As A Mainstream Phenomenon, Bernard E. Rollin

Bernard Rollin, PhD

The 20th century has witnessed a bewildering array of ethical revolutions, from civil rights to environmentalism to feminism. Often ignored is the rise of massive societal concern across the world regarding animal treatment. Regulation of animal research exists in virtually all Western countries, and reform of “factory farming” is regnant in Europe and rapidly emerging in the United States. In 2012, a series of articles in The New York Times focused welfare attention squarely on the horse industry. Opponents of concern for animals often dismiss the phenomenon as rooted in emotion and extremist lack of appreciation of how unrestricted animal …

When Too Much Isn’T Enough: Does Current Food Production Meet Global Nutritional Needs?, Krishna Bahadur Kc, Goretty M. Dias, Anastasia Veeramani, Clarence J.

Sustainably feeding the next generation is often described as one of the most pressing “grand challenges” facing the 21st century. Generally, scholars propose addressing this problem by increasing agricultural production, investing in technology to boost yields, changing diets, or reducing food waste. In this paper, we explore whether global food production is nutritionally balanced by comparing the diet that nutritionists recommend versus global agricultural production statistics. Results show that the global agricultural system currently overproduces grains, fats, and sugars while production of fruits and vegetables and protein is not sufficient to meet the nutritional needs of the current population. Correcting …

Perceptions Of On-Farm Emergency Slaughter For Dairy Cows In British Columbia, Katherine E. Koralesky, David Fraser

David Fraser, PhD

Some jurisdictions permit on-farm emergency slaughter (OFES) as one end-of-life option for dairy cows and other animals that cannot be transported humanely but are deemed fit for human consumption. Anecdotal reports suggest that OFES is controversial among dairy industry professionals, but to date their perceptions of OFES have not been studied systematically. Twentyfive individual interviews and 3 focus groups with 40 dairy producers, veterinarians, and other professionals in British Columbia, Canada, revealed positive and negative perceptions of OFES influenced by (1) individual values, (2) the perceived operational legitimacy of OFES, and (3) concern over social responsibility and public perception of …

Use Of On-Farm Emergency Slaughter For Dairy Cows In British Columbia, Katherine E. Koralesky, David Fraser

David Fraser, PhD

On-farm emergency slaughter (OFES), whereby inspection, stunning, and bleeding occur on the farm before the carcass is transported to a slaughterhouse, is permitted in some jurisdictions as a means to avoid inhumane transportation while salvaging meat from injured animals. However, OFES is controversial and its use for dairy cows has been little studied. Inspection documents for 812 dairy cows were examined to identify how OFES was used for dairy cows in British Columbia, Canada, over 16.5 mo. Producers used OFES for dairy cows aged 1 to 13 yr (median of 4 yr). Leg, hip, nerve, spinal, foot, and hind-end injuries …

Management Of Cull Dairy Cows—Consensus Of An Expert Consultation In Canada, Jane Stojkov, G. Bowers, M. Draper, Todd Duffield, P. Duivenvoorden, M. Groleau, Deb Haupstein, R. Peters, Jane Pritchard, C. Radom, N. Sillett, W. Skippon, H. Trépanier, David Fraser

David Fraser, PhD

Many cull dairy cows enter the marketing system and travel to widely dispersed and specialized slaughter plants, and they may experience multiple handling events (e.g., loading, unloading, mixing), change of ownership among dealers, and feed and water deprivation during transport and at livestock markets. The objectives of this study were to describe the diverse management of cull dairy cows in Canada and establish consensus on ways to achieve improvements. A 2-day expert consultation meeting was convened, involving farmers, veterinarians, regulators, and experts in animal transport, livestock auction, and slaughter. The 15 participants, recruited from across Canada, discussed regional management practices …

Public Attitudes To Housing Systems For Pregnant Pigs, E. B. Ryan, David Fraser, Daniel M. Weary

David Fraser, PhD

Understanding concerns about the welfare of farm animals is important for the development of socially sustainable production practices. This study used an online survey to test how views on group versus stall housing for pregnant sows varied when Canadian and US participants were provided information about these systems, including access to scientific papers, YouTube videos, Google images, and a frequently-asked-questions page (S1 Appendix). Initial responses and changes in responses after accessing the information were analyzed from Likert scores of 242 participants and from their written comments. Participants were less willing to accept the use of gestation stalls after viewing information …

Effect Of Sand And Wood-Shavings Bedding On The Behavior Of Broiler Chickens, S. J. Shields, J. P. Garner, J. A. Mench

Sara Shields, PhD

The purpose of this study was to determine the effect of 2 different bedding types, sand and wood shavings, on the behavior of broiler chickens. In experiment 1, 6 pens were divided down the center and bedded half with sand and half with wood shavings. Male broilers (10/pen) were observed by scan sampling at 5- or 12-min intervals throughout the 6-wk growth period during the morning (between 0800 to 0900 h), afternoon (1200 to 1500 h), and night (2300 to 0600 h). There was a significant behavior x substrate x week interaction during the day (P < 0.0001) and at night (P < 0.0002). Drinking, dustbathing, preening, and sitting increased in frequency on the sand side but decreased on the wood shavings side during the day, as did resting at night. In general, broilers performed a greater proportion of their total behavioral time budget on the sand (P < 0.0001) as they aged. Broilers used the divider between the 2 bedding types to perch; perching behavior peaked during wk 4. In experiment 2, male broilers were housed in 8 pens (50 birds/pen) bedded only in sand or wood shavings. Bedding type had no effect on behavioral time budgets (P = 0.8946), although there were age-related changes in behavior on both bedding types. These results indicate that when given a choice, broilers increasingly performed many of their behaviors on sand, but if only one bedding type was provided they performed those behaviors with similar frequency on sand or wood shavings.

A Decade Of Progress Toward Ending The Intensive Confinement Of Farm Animals In The United States, Sara Shields, Paul Shapiro, Andrew N. Rowan

Sara Shields, PhD

In this paper, the Humane Society of the United States (HSUS) farm animal protection work over the preceding decade is described from the perspective of the organization. Prior to 2002, there were few legal protections for animals on the farm, and in 2005, a new campaign at the HSUS began to advance state ballot initiatives throughout the country, with a decisive advancement in California (Proposition 2) that paved the way for further progress. Combining legislative work with undercover farm and slaughterhouse investigations, litigation and corporate engagement, the HSUS and fellow animal protection organizations have made substantial progress in transitioning the …

Sex Differences In The Herding Styles Of Working Sheepdogs And Their Handlers, Erin Kydd, Paul Mcgreevy

Paul McGreevy, PhD

Working sheepdog trials test the attributes of dogs as well as the dogmanship and stockmanship skills of handlers. They generally include standard elements such as outrun, lift, fetch, drive, shed, pen and single to test all facets of the work that dogs perform on a farm. While both male and female handlers participate, these trials are traditionally dominated by male handlers. Both male and female dogs compete on equal terms within the same events. Drawing data from files (n = 60) downloaded from YouTube, the current study explores whether behaviours of dogs and their handlers during sheepdog trials differ between …

Using The Five Domains Model To Assess The Adverse Impacts Of Husbandry, Veterinary, And Equitation Interventions On Horse Welfare, Paul Mcgreevy, Jeannine Berger, Nic De Brauwere, Orla Doherty, Anna Harrison, Julie Fiedler, Claudia Jones, Sue Mcdonnell, Andrew Mclean, Lindsay Nakonechny, Christine Nichol, Liane Preshaw, Peter Thomson, Vicky Tzioumis, John Webster, Sarah Wolfensohn, James Yeates, Bidda Jones

Paul McGreevy, PhD

The aim of this study was to conduct a series of paper-based exercises in order to assess the negative (adverse) welfare impacts, if any, of common interventions on domestic horses across a

broad range of different contexts of equine care and training. An international panel (with professional expertise in psychology, equitation science, veterinary science, education, welfare, equestrian coaching, advocacy, and community engagement; n = 16) met over a four-day period to define and assess these interventions, using an adaptation of the domain-based assessment model. The interventions were considered within 14 contexts: C1Weaning; C2 Diet; C3 Housing; C4 Foundation training; C5 …

Ranking Of Production Animal Welfare And Ethics Issues In Australia And New Zealand By Veterinary Students, Amelia Cornish, Andrew D. Fisher, Teresa Collins, Chris Degeling, Rafael Freire, Susan J. Hazel, Jennifer Hood, Jennifer K.F. Lloyd, Clive J.C. Phillips, Kevin J. Stafford, Vicky Tzioumis, Paul Mcgreevy

Paul McGreevy, PhD

The importance of animal welfare and ethics (AWE) within the veterinary education should reflect community concerns and expectations about AWE, and the professional demands of veterinary accreditation on the first day of practice (or ‘Day One’ competences). Currently, much interest and debate surrounds the treatment of production animals, particularly around live export. To explore the attitudes to AWE of veterinary students in Australia and New Zealand, a survey was undertaken to (i) understand what students consider important AWE topics for initial production animal competence; and (ii) ascertain how these priorities correlated with gender, area of intended practice and stage-of-study. The …

Uncaging New Zealand's Sows: Scrutinizing Farrowing Crates, Andrew Knight

Andrew Knight, PhD

This 13,000 word report was published by SAFE (a leading NZ animal advocacy organisation). It documents the welfare problems experienced by around 15,000 New Zealand sows annually, who are confined within metal cages barely larger than their own bodies, in a practice claimed to decrease piglet mortality. It was delivered to NZ’s Primary Production Select Committee along with SAFE’s own submission in June 2018. The Committee was reviewing a 112,844 signature petition to Parliament (the largest in 5 years), which requested a ban on sow farrowing crates.

Does The Seal Licensing System In Scotland Have A Negative Impact On Seal Welfare?, Laetitia Nunny, Fritha Langford, Mark P. Simmonds

Mark P. Simmonds, OBE

This study examined the licensing system that permits seal shooting in Scotland, which was established under Part 6 Conservation of Seals of the Marine (Scotland) Act 2010. Four approaches were used: data were collated and analyzed from both the Scottish Government and Scottish Marine Animal Stranding Scheme; a survey was sent to current license holders and informal interviews were conducted with key stakeholder types. Between February 2011 and the end of October 2015, 1229 gray seals, and 275 common seals were reported shot under license to the Scottish Government. The numbers of seals reported as shot has reduced year-on-year since …

Turning Science Into Policy: The Case Of Farm Animal Welfare In Canada, David Fraser

David Fraser, PhD

Implications

• Development of farm animal welfare standards in Canada has evolved significantly over 35 yr in terms of process, leadership, and the role of science.
• Key elements of the current process include: 1) influential producers and producer organizations that see the benefit of having science-informed standards, 2) a credible coordinating body to ensure that a well-defined process is followed in developing standards, and 3) trusted scientists who are engaged in relevant research and willing to participate.
• The process benefits from having a distinct and defined role for the scientists, specifically to analyze relevant science and identify conclusions that are scientifically …

Valuable Behavioural Phenotypes In Australian Farm Dogs, P. D. Mcgreevy, C. M. Wade, E. R. Arnott, J. B. Early

Paul McGreevy, PhD

This report presents findings regarding the ways to optimise the performance of livestock working dogs in Australia. The methods available to optimise dog performance include both environmental and genetic factors. The objectives of this study were to identify objective measures of desirable behavioural phenotypes in Australian livestock working dogs and explore genetic parameters of these 'quality of working life' traits within the Kelpie breed. The document reports on genotyping that reveals gene-behaviour associations and describes heritability estimates that underpin a database for potential estimated breeding value (EBV) calculations.

General Principles For The Welfare Of Animals In Production Systems: The Underlying Science And Its Application, David Fraser, Ian J.H. Duncan, Sandra A. Edwards, Temple Grandin, Neville G. Gregory, Vincent Guyonnet, Paul H. Hemsworth, Stella M. Huertas, Juliana M. Huzzey, David J. Mellor, Joy A. Mench, Marek Špinka, H. Rebecca Whay

David Fraser, PhD

In 2012, the World Organisation for Animal Health adopted 10 ‘General Principles for the Welfare of Animals in Livestock Production Systems’ to guide the development of animal welfare standards. The General Principles draw on half a century of scientific research relevant to animal welfare: (1) how genetic selection affects animal health, behaviour and temperament; (2) how the environment influences injuries and the transmission of diseases and parasites; (3) how the environment affects resting, movement and the performance of natural behaviour; (4) the management of groups to minimize conflict and allow positive social contact; (5) the effects of air quality, temperature …

Attitudes Of Canadian Citizens Toward Farm Animal Welfare: A Qualitative Study, Jeffrey M. Spooner, Catherine A. Schuppli, David Fraser

David Fraser, PhD

As part of a larger project to determine if there are animal-welfare-related values shared by some commercial food–animal producers and non-producers in Canada, open-ended, semi-structured interviews were conducted to elicit opinions about animal welfare among 24 urban and rural residents not involved in commercial animal production. All participants possessed a self-described interest in food animal well-being and were therefore assumed to represent the views of Canadian non-producers most apt to engage in efforts to shape the animal welfare policies of governments and businesses. Participants described animal welfare in moral or ethical terms, expressed virtually unanimous support for animals having access …

Attitudes Of Canadian Beef Producers Toward Animal Welfare, J. M. Spooner, C. A. Schuppli, D. Fraser

David Fraser, PhD

Commercial beef production in western Canada involves raising cows and calves on large tracts of grassland, plus grain-based ‘finishing’ of animals in outdoor feedlots. This study used open-ended, semi-structured interviews to explore views on animal welfare of 23 commercial beef producers in this system. Although wary of the term ‘animal welfare’, participants understood the concept to encompass three well-known elements: (i) basic animal health and body condition; (ii) affective states (comfort, contentment, freedom from hunger or thirst); and (iii) the ability to live a ‘natural’ life. Participants attached importance to protecting animals from natural hardships (extreme weather, predators), yet many …

Attitudes Of Canadian Pig Producers Toward Animal Welfare, Jeffrey M. Spooner, Catherine A. Schuppli, David Fraser

David Fraser, PhD

As part of a larger study eliciting Canadian producer and non-producer views about animal welfare, open-ended, semi-structured interviews were used to explore opinions about animal welfare of 20 Canadian pig producers, most of whom were involved in confinement-based systems. With the exception of the one organic producer, who emphasized the importance of a ‘‘natural’’ life, participants attached overriding importance to biological health and functioning. They saw their efforts as providing pigs with dry, thermally regulated, indoor environments where animals received abundant feed, careful monitoring and where prospective disease outbreaks could be minimized and controlled. Emphasis was also placed on low-stress …

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 …

Diversity Of Behaviour During Novel Object Tests Is Reduced In Pigs Housed In Substrate-Impoverished Conditions, Françoise Wemelsfelder, Marie Haskell, Michael T. Mendl, Sheena Calvert, Alistair B. Lawrence

Françoise Wemelsfelder, PhD

Modern intensive farming conditions lack the diversity of substrates present in more natural environments and offer young animals fewer opportunities for interaction. Evidence exists that this may affect the organization of interactive patterns of behaviour, but shifts in behavioural diversity have not been measured directly. We investigated the effect of the substrate in the home pen on the diversity of behaviour in young growing pigs, Sus scrofa. Over 5 months, 26 pigs were housed singly in either substrate-impoverished (SI) or substrate-enriched (SE) conditions. Once every month we recorded the behaviour of these pigs in detail both in the home pens …

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 …

Flooring And Driving Conditions During Road Transport Influence The Behavioural Expression Of Cattle, Catherine A. Stockman, Teresa Collins, Anne L. Barnes, David Miller, Sarah L. Wickham, David T. Beatty, Dominique Blache, Françoise Wemelsfelder, Patricia A. Fleming

Françoise Wemelsfelder, PhD

This study examined whether observers could distinguish between cattle that were exposed to various road transport conditions: Experiment 1 compared a manipulated flooring treatment (non-grip flooring, NG) with a control transport event (grip flooring, G) and Experiment 2 compared a manipulated driving style (stop-start driving, SS) with a control transport event of smooth, continuous (C) driving. The behavioural expression of cattle was assessed through the process of Qualitative Behavioural Assessment (QBA), and these assessments were tested for correlation with various physiological parameters. Fourteen Angus steers were assessed. Blood samples were collected immediately before and after transport, and heart rate and …

Experience In Substrate-Enriched And Substrate-Impoverished Environments Affects Behaviour Of Pigs In A T-Maze Task, Michael Mendl, Hans W. Erhard, Marie Haskell, Françoise Wemelsfelder, Alistair B. Lawrence

Françoise Wemelsfelder, PhD

Previous research showed that pigs reared in substrate-impoverished conditions performed a smaller proportion of their total behavioural repertoire in their home pens (showed lower behavioural diversity), than pigs reared in substrate-enriched conditions. This study examined whether these differences were the result of fundamental changes in behavioural organisation. A T-maze task was used to test the hypothesis that substrate-impoverished pigs are prone to develop fixed, unvarying behaviour which may underlie their reduced behavioural diversity. They were predicted to be poorer at reversing previous response patterns in the maze, and less able to alter their behaviour in response to a novel (distracting) …

Welfare Assessment: Correlations And Integration Between A Qualitative Behavioural Assessment And A Clinical/Health Protocol Applied In Veal Calves Farms, Marta Brscic, Françoise Wemelsfelder, Elena Tessitore, Flaviana Gottardo, Giulio Cozzi, Cornelis G. Van Reenen

Françoise Wemelsfelder, PhD

This study is aimed at finding correlations and possible integration among Qualitative Behavioural assessment (QBA) and a specific protocol of clinical/health evaluation. Both welfare assessment methods were based on direct animal observation and were applied in 24 Italian veal calves farms at 3 weeks (wks) of rearing. Principal component analysis (PCA) summarized 20 QBA descriptors on two main components (PC1 and PC2) with eigenvalues above 4 and explaining 29.6 and 20.3% of the variation respectively. PCA on residuals obtained after correcting for housing condition yielded highly similar results, indicating that the rearing environment of the calves was not an important …
